Hello Hbaba,
> I'm doing the 90 deg setup now and the results are poor in a variety of ways.
What item are you scanning? Is it recognizable? Is it distorted? Is there a lot of unknown or unwanted stuff cluttering the scan?
What camera are you using? Can you setup AGC for Peak rather than the more common Average? If not, can you set the exposure time very low so that the laser is visible while the background is black?
If camera is upside down, did you select mirror and flip options in the Mach3 camera setup? If not, calibration is screwy and I have no idea what that does to the math. If not sure, post a screen shot with your calibration bar in place right after you calibrate.
Try scanning your calibration bar. Does the point cloud look like a square bar? If so, can you determine the size of the square bar from the point cloud?
Can you post some of your results?
Some stuff that would be informative:
Photo of your camera/laser setup.
Screen shot of probe video on Mach3.
Output (text file) from a scan that you are not happy with.
JPEG file showing views from various angles from MachCloud or other software.
> Do you have any before/after scans to share that came out well?
Not sure what you mean by "before/after" but I only have that one good scan of the key. I do have one of a penny but it does not show enough detail to say that it is anything but a disc.
My only probe is out of my hands at the moment. Should be able to do more next week when I get it back or maybe make another probe if I find time.
BTW, another camera that looks promising is the Playstation "Eye Toy". It does not have Peak AGC but does have the ability to turn AGC off and set exposure time very short. Not short enough to black out the background so it works better with house lights out or at least very dim.
