AW: image-acquisition package install

[Dominic Bitter]

Hello Kire,

thanks for the code.

 

I have a Matlab script from a colleague which (if i remeber it right) is able to get live images from USB cams.

Sadly i can’t get a Matlab license for me there.

If it can help you i can ask him on Monday and send you the file.

Dominic,

 

I am busy implementing webcam support on Windows.

I based it on the interface described by the webcam package of matlab

https://nl.mathworks.com/help/supportpkg/usbwebcams/index.html

 

It is currently in a very early and rough stage. No help yet, very dirty code, etc. I only managed to get it working today, but it can already obtain images. Also Brightness, backlight etc, can be set. No resolution control at the moment.

Once I have everything working, I might try and integrate it in the img-acq package.

 

>> pkg load webcam
>> webcamlist
ans =
{
  [1,1] = VGA Webcam
  [2,1] = HD 720P Webcam
}
>> cam=webcam(1);
warning: This is work in progress, be prepared for segfaults
warning: called from
    webcam at line 8 column 15
>> cam.get()
ans =

  scalar structure containing the fields:

    Name = VGA Webcam
    Resolution = 640x480
    AvailableResolutions =
    {
      [1,1] = 640x480
      [2,1] = 640x360
    }
    Brightness = 0
    Contrast =  32
    Hue = 0
    Saturation =  64
    Sharpness =  4
    Gamma =  221
    WhiteBalance = auto
    BacklightCompensation = off
    Exposure = auto

imshow(cam.snapshot);
