Integrated thermal camera
Hi,
When can we get an integrated thermal camera to a laser scanner? Who will be the first one to release this?

Re: Integrated thermal camera
Why would you want it internal? Consider the size and cost of what you are asking and there is no way it would make economic sense. Flir is a well known leader in thermal camera technology so the laser scanning companies can't be expected to start developing their own thermal technology unless there is a lot of $$ to be made.
Riegl and Z+F have both demonstrated thermal integration and it works very well from what I can tell.

Re: Integrated thermal camera
Well i guess it does not matter where the technology comes from, but I would like to see the thermal camera built inside the scanner. If there is a thermal camera inside the Cat mobile phone, I guess they could put it inside a laser scanner also?

Re: Integrated thermal camera
Help me out here...why the need to be inside the scanner? Are you doing thermal scanning exclusively? The resolution of thermal cameras is terribly low and the cost of a high resolution thermal system is about as much as a scanner.

Re: Integrated thermal camera
I am not an expert on this area, but I think it would be nice to be able to swap between intensity, rgb and thermal view. I guess a few years ago someone could have asked why do you need a digital camera inside the scanner to make rgb color scans.

Re: Integrated thermal camera
I would go one step further and say why not a complete hyperspectral imaging system. The answer is always the same...hard to justify for cost. I think a simple RGB camera is easy enough as the sensors have been mass marketed to death. Thermal...not so much. There are low cost systems that you can attached to your iPhone, but they are very low resolution and the sensitivity isn't so great. In any case, if it interests you, there have been previous posts here by Jonathan Coco about how to integrate thermal images from a handheld Flir camera to a Focus scanner...pretty cool stuff.

Re: Integrated thermal camera
Ok, thanks for the info.
I found out that the Cat S60 phone is using Flir Lepton imager which has a resolution of 80x60 (4800) pixels:

If it would be used like the rgb camera in the Focus e.g. which takes 85 images this would give a total resolution of 408000 pixels (or little less) to the panoramic thermal images.

Re: Integrated thermal camera
Thanks Eugene, I was just about to chime in, but you pretty much answered this the same way I would have.
Echoing what you said, the cheap thermal sensors are to low in resolution to provide much useful detail at range. You could still obtain some useful information about close things, but it would look more or less like a irregular pixelated blob pasted on top of a highly detailed high resolution scan. Marko, even if the Lepton sensor could be used in place of the color camera in the Focus you would not achieve 408000 pixels as a good part of every image is thrown away due to the fact that the body of the scanner is in large portions of the image. See video here:http://www.laserscanningforum.com/forum ... 651#p18651
The Z+F T-cam is really quite elegant from what I have seen, but they could possibly integrate a thermal sensor next to the other camera on the back of the mirror if they really wanted to which would make the RGB and thermal picture sequences simultaneous. Other manufacturers with the color camera integrated in the body behind numerous optics would have to re-think the way the integrate the sensor as thermal cameras cannot see through glass.
Enough of my blabbering here though, if you really want to know what I think and have the fortitude to read what is possibly the longest single post on this forum then enjoy:http://www.laserscanningforum.com/forum ... =10#p37691
