Positive and negative laser scanner.

laser Discussion scanner.

I have been using and researching the laser scanner since 2003 since my stay in Sweden, doing my final project laser scanner. With the creation of the company GAVLE: Heritage Documentation Graphics 've seen up close as the laser scanner is a myth to some and a false promise for others, but, frankly, few see a true picture of this instrument in various fields that this instrument can be applied. Here's why this humble contribution.

could talk history and progress of the laser scanner in recent years, as have been many and have created some engineers archaic ideas about this technology as files that are too large and can not be handled well, or have no output to CAD, which is a very expensive technology ... so how are you and other assertions are completely false several today ...

Arremangémonos. A file in a scanner can be taken with weight varies, depending on the resolution and the laser mark, but more importantly they are perfectly manageable by current software. A project large, with photo texture and triangulation can be about 4GB .. ie, any hard disk you could stand, 3GB of RAM is more than what is needed to process all these data. What you can not ask all these data is to manage all the properties photorealistic and triangulation with commonly used software such as AutoCAD ... should pave the way for export. But yes, exit to CAD!

can export the entire file ... if you want, but more normal is that the user is lost in the maremagnum points and despair in trying to move ... the optimum is to separate what you want and pass it to CAD ... if you want to measure crashes, do the sections in the LS software and export to DXF CAD, if you raised, you make an orthophoto and export to CAD as an image, if you want only certain points, clean the LS software left over to export to DXF and the points you want ... and so on. It is not about killing flies with cannon fire.

Is it expensive laser scanner?

Of course it's expensive aircraft, but the service that goes profitable thousands of transport companies daily throughout the world. Something about the laser scanner, 'could you pick up in 1 hour a square of 900m2 with a total station or photogrammetry, with all the details of facades, textures and geometries of 6 millimeters? the answer is obviously No! hence the reason that the myth of expensive than the LS has more bark than bite. I work with Laser Scanner for 7 years and I can assure that work out profitable, if you know you do with it and not use the laser for everything and in any way. This point is very large and complex to explain, but the profitability of the laser is based on several points: the extension and complexity of work, architectural, archaeological requirements (or industrial, mining or other applications), the merger and optimization of results with other techniques and, finally, I would say is essential expertise and knowledge of engineering technology-operator that uses it. But I insist that, generally, and with a good approach and knowledge, the LS is profitable.

What aspects negative is the laser scanner?

seem that everything is good in this instrument, but it is not. Firstly I refuse to name the negative side there are hidden areas, because the problem is that of all existing capture techniques, what is not does not appear and that is the case with the laser, photogrammetry and with the tape, if you will excuse the irony.

What I see as negative is that the laser scanner itself is nothing. Accurate total station for georeferencing models and to perform the relevant quality control: it scans the union of accumulating errors and these should be checked and corrected, if necessary, using a non-prism Total Station (speaking of architectural heritage) .

Another negative aspect is that the achievement texture is still at an early stage ... if we are lucky and the day is cloudy, the light conditions are homogeneous and can be used built-in camera LS, if known ... that it is normal to have it. But if not, projecting shadows on the facades are made of lifting a spectacle of lights and shadows and impossible to present ... so the solution is two possibilities: one is shooting another day with favorable light conditions, with a camera and ortoproyectarla semimétrica metric or on the point cloud ... this tedious work and not always easy. And the second solution is photogrammetry using control points the same LS georeferenced. In either case ... more work, if you want to present is a good project.

Why so much information?

I have met many people asking what it requires as much information as the LS capture. Well, it may be that most jobs do not require so much information, so this statement is true, but the example I can think of moving, I repudiated the camera phones, Internet connections of these, etc ... things that I never will use and I was needed. I resisted the consumerist vortex until I had no choice and I gave it away to start a new contract ... I still use it yet, but I'll bring everyone. This example is a collation of information overload ... if not need, do not use it, if you need it, use it, not much more to tell, because if the technology is profitable for a project, but give you much more than what you ask, that's not a problem, if information is no problem when using it, as in this case. But allow me to one final explanation for the use and optimization of this information in the following point:

Orthophotography obtained from a survey with a laser scanner.

Why the laser scanner and not other techniques?



First I did not disown the other techniques, in fact, whenever I use photogrammetry and topography to merge with the LS. But call the attention of architects and developers work to restore the architectural and archaeological heritage to know use the full potential of the laser at different phases of the work:



1 º do a survey before the monument is a practice still booming, but not by all, much less. And that's because they are unaware that you can save this action. You can save by looking at the survey areas to remodel, and plan to measure them accurately, perform calculations and material timings tighter. That would cheapen the work. And with the laser scanner ...







2 º the excess of information that we discussed in the previous point, would not make any trouble if the philosophy of the data obtained by the laser was different: I mean that this information is used throughout the restoration process, not only in the preliminary work and planning, but used to go consulting crashes, volumetric necessary consultations and 3D measurements unforeseen during the development of the work, etc. The architect may find here a very useful tool to monitor the development of the work. If the survey has been carried out with photogrammetry and total station is more than possible that no data were taken in such detail and with the foresight that all queries resolved after the architect, and with these techniques is that surveys develop from specific points and the laser scanner is a mass trapping technique.







3 º can serve and serve, to make presentations and virtual animations. something needed to sell the work for reuse in advertising or include interpretive centers, internet, etc. Also photogrammetry and 3D design software with 3D Studio Max or Blender) can do this too, but with an ability to traverse or smaller mesh and therefore less realistic.




......................
Finally, I have nothing else to bet on this new technology with suitable reserves and always with the knowledge necessary to make this a tool that provides a real service and complete the works of architectural and archaeological restoration.

nothing else, I hope you support has resulted from this short article and do not hesitate to write me with any questions or queries. Pedro Ortiz

Who are the culprits of the global crisis

I disastri di una finanza che distribuisce ricchezza senza produrla saranno pagati dai più weak. From the Republic, January 12, 2009 (mpg)

says Giovanni Sartori: "2009 will be the first year - I fear - a perfect economic storm. A storm that lasts as long as we're not going to understand how the money comes, what does wealth. " (Corriere della Sera, December 31) ... And I'm afraid that I was right. Then
accused the left of the responsibility to have misrepresented the issue by putting the issue of wealth distribution to the problem of wealth creation. Now, if it comes to this crisis, it seems to me that, for once, the "left" is innocent.
God only knows if the left has made fatal errors. Dented to the point of staying and lead us to rely on his critics not to fire on the ambulance. It's true. At a time when it had a favorable political balance of power, forced sometimes to wage demands (even if you have to qualify: In some cases, as in our present, an increase in wages is imposed because of the crisis).
But since this is the storm in which we find ourselves, I think it goes without saying that it was packaged in America by a right-wing government, in compliance with a policy that could not be more disegualitaria. The next European type, which implicitly refers Sartori, America does not even exist and therefore must be paid for not having committed the crime.
But there's more. The charge that Sartori moves to the left is perfectly suited to the right "liberal." What is, in fact, the "special film" of the crisis if not what to have for years distributed wealth exist? On three separate but converging planes.

At the global level, America has lived and still live with resources far superior to those that produce, funded by Asian savings of sobriety and realizing the parable of the rich debtor. In terms of the national economy the high pressure fuel, which has so far maintained its claim to high levels, is based on a huge debt of American families, with good Peace of Max Weber, have long ceased to spare. What quell'indebitamento which originated from the U.S. crisis, if not wealth distributed without being produced?
Finally, on the enterprise, large enterprise, the Corporation, what are the gains of the endless American managers, their fabulous salaries, their stock options, their settlements monumental, if not advantageous position: differences between market values \u200b\u200bthat they themselves are able to influence and actual values? This is also distributed wealth without being produced. Sartori
fought long and valiantly against the irresponsible proliferation of criminal conviction that population suffering hunger to death millions of innocent children. They can not escape the disasters of a finance based on the proliferation of irresponsible borrowing.
Finance has many merits. It provides liquidity to savings and investment. It helps, if managed with prudence, to cover the risks of investing, More. Within certain limits, even its "bets" may encourage investment decisions that are made. Within certain limits, which were swept away irresponsibly creating this latest crisis.

have sometimes been accused of "finanzobia. If it were up to me, it was said, there would not even check. No, I said and I repeat. The allowance we would be. There would be no bad checks.

remains the exemplary Sartori's statement on the need to understand how the money comes, what does wealth. Above all, and I think you will agree with me, the real wealth, not imaginary. And not at the expense of the innocent. It has been said that the debt goes to inordinate burden of our posterity. And Woody Allen said: What's wrong? After all, what did the posters for us? But it is not true. When the bubbles burst, and inevitably break out in our time are the contemporaries to pay. First, those who have been enriched with non-produced wealth, and then taken away from other: the unemployed, defrauded investors, taxpayers have to solve problems that others have created.

CONSOLIDATION OF THE MONUMENT.
The company played in Gavle three-dimensional enclosure of the citadel
The study will help us understand how it is to prevent possible riesgos.Las laser images are captured and are very accurate.

Gavle emeritense company yesterday began work for an archaeological and architectural survey of the Arab castle site in three dimensions. To do this they are using 3D Laser Scanner apparatus with an accuracy of 6 mm. difference and a texture comparable to those of high-definition photography.
The director of the company, Pedro Ortiz, said that this method get a three dimensional model of the enclosure of the citadel "with great precision."

Once captured the site in three dimensions can be managed and measured in the computer and is very helpful in making studies of potential crashes, knowing the conditions you may have and possible interventions to be carried out.

The lifting of the enclosure is conducting intramural and extramural, including towers, turrets, towers flanking and santiaguista convent.

This action in the Arab castle has been entrusted to the company Resgal Gavle, winner of the competition held by the Ministry of Culture to strengthen damaged areas of the fortress, built in the ninth century.

Among the works undertaken so far within this project, which is funded by the Ministry of Culture under the supervision of a multidisciplinary team of archaeologists, engineers and architects, highlights the underpinnings of the towers, the injected mortar fluid in the paintings and the protection of upland areas with impervious mesh.
also is engaged in the alcazarejo, which will open to the public and will be the gateway for tourists to gain access to the citadel.
