WebCam Data

[DanL]

I have run in to a big problem the X and Y are the same as the aspect size but Z is coming out as just over 3 meter in depth I change x to 200 it goes down to 1 M

Dan:

  Wow, those are pulling out nicely.. just lower your scale slider, it should lower back to a reasonabel pull, I aim for about 150 as a good scale.. but it varies from data to data set..

yer they are better than my laser scanner can do I will try that

[DanL]

Hi art moving the slider down to 1 leaves not a very good image, having it set to 2.5 is a lot better but it has a 80 mm curve ever negative or image it`s all the same.

so the scale of negative to image is good

but the curve is way to much the whole image will be curved cutting the side of helps a little bit.

I have tried a flat black back ground it make`s it worse bigger curve.

A flat white back ground is better, between black and white is 200 mm

it would be good if you can reduce the Gradient scale so if its at 10 it would be 1/4 or less of what it is now but keeping the image just as good or have it how it was in the last version I tried the one on your site had barely any curve to wear there was a flat back ground sorry to be a pain

picks 1 is negative, 1 on gradient scale pick 2 is negative, 2.5 on gradient scale, picks 1a, 2a is image same setting`s 

threshold is 0.1, zero noise gradients is un ticked, ambient correction same, fullres resolution is 176 x 144 yuy2--format 2

been playing with the web cam on my laptop the differences from the webcam in a box to the one on the laptop is massive everything comes out fine with the webcam on my laptop.

I thinks it just that there is no back ground noise in the box so the changes you made are to much if the webcam has no back ground noise and is in a box I will try having the web cam sitting on my laptop to see what happens I will post those latter

[DanL]

here is a pick done with my webcam sitting on my laptop I have background lights on so its not the best but it half the depth of doing it in my scanner box with the Gradient scale at 3

Dan:

  Also, look closely at the images, any chance the timing is off on the scanner box? The photo is actually taken at the end of the flash cycle, not at the beginning. When the screen flashes the one side, you have
to be pretty carefull about when exactly that photo is taken.
  I guess I really need to put out a trigger just in case for people like yourself that can use external
processes.. But your right, it could just be your images are too good.. Of course, you dont need to use Gearotic at all for taking of the pictures, so long as you save them in alphabetical order so the
reconstruction knows which is which..
 
    In the fall when I revisit the 3dfromwebcam, Ill get some images from you and analyse why
their so strong. Ive moved on to a new investigation now that will keep me busy till the fall,
so we'll discuss this in more detail then. The new 3d will be released than as well.

Thx

ok sweet I will play with what is there now and just fart around with it I might try a infinity wall so there is not a background for the cam to pick up I will do a negative and positive to see what happens, it a bloody good program.

I whacked the slider to the max`s it was very very deep 6 m but what was at the end was really sharp and clean.

I will post picks if the infinity wall works and its just a second screen in the box and its just a cheap webcam with auto focus and zoom.

thank you for another one of your cool products and letting me play with it

Dan:

  Excellent, let us know how it works out.

hi art I have gone back to the dev version of gearotic I could not get anything useful out of the version you sent me with out being 100 mm plus deep I played for quite a long time everything I tried somethings helped some not.

I think the problem is the webcam I am using compered to what you have mines a Genius FaceCam 1020.

I have it set to 640 x 480 YUY2
250ms
Confidence is around 100
Gradient Scale 1.50
pedestal closure ticked (what ever it for)

pick attached I got a new program for the web cam I have and can zoom in and pan with it.

so it is better than any other program for scanning I have now
