WHOAREU (Motion detection with a webcam)

Intrigued · Post by **Intrigued** » Thu Oct 13, 2005 4:01 am

It's sometimes, now, capturing images to a folder (to the Desktop I've chosen, coo'!). I believe the Max sensitivity needs to be cranked up a good ways still. At least that's what it seems to be the problem now, on my system.

SCRATCH THIS POST (I left it up so that I can explain a point).

If the lighting is to low... the capture's do not happen. Now, I just had my cam turned to the ceiling a few feet from where a ceiling fan with 5 lights are on burning all at either 60 (or 1 at 40) watts. So, there should be enought light to activate the captures, but it seems not. As when I moved it so that my face was showing but the lights where in the capture area.. BANG! It works great!

Can this be handled in code or it's a Web cam thing? (I have a cheap $40 laptop unit).

I think a better motion detection is needed. But, for now, I have posted a new version with a big corrected failure.

Also I have changed the method of change of sensitivity and copy webcam image method (Without #WM_CAP_EDIT_COPY)

Remember to configure your webcam to 320*240 and 24 bits

Now it's not capturing any, no matter how much light (incandescent bulbs) I shed onto the camera, or how little.

But, the resizing and positioning of the capture area seems to work. Well it allows for both actions with no crashing now.

I incremented too much the sensibility and a variable.w was converted to negative value.... sorry.... and ... solved

Hmm, all I'm seeing is a black screen.

Please, ensure to configure your webcam to 320*240 and 24 bits

It is. I can see my image in the "Capture Zone Config" but not on the main screen.

Yes, I changed the Copy Method for capture the webcam image to memory... I'll try to return to old method (#WM_CAP_EDIT_COPY ) And test it

zikitrake · Post by **zikitrake** » Sat Oct 15, 2005 3:35 pm

Ok, I replaced the new Image Copy Method to the old method.

Please, test it and tell me

Works again!

The application now crashes on me at times, when it begins Start Monitoring activities. And, it's not sensitive enough still.
