hy i would like to start working with image processing toolbox, but I cant install the winvideo driver for my Acer s3 391 built in webcam. {I tried also my old usb web cams, but in the windows 10 device manager cant find the driver for these (genius videocam slim usb 2, lg an vc300 al,...)} I also installed the usb cam driver with matlab 2016a command>>supportPackageInstaller
When i type: imaqhwinfo
InstalledAdaptors: {'dcam'}
MATLABVersion: '9.0 (R2016a)'
ToolboxName: 'Image Acquisition Toolbox'
ToolboxVersion: '5.0 (R2016a)'
also when imaqhwinfo('dcam')
AdaptorDllName: 'C:\MATLAB\SupportPackages\R2016a\toolbox\imaq\supportpackages\dcam\ad…'
AdaptorDllVersion: '5.0 (R2016a)'
AdaptorName: 'dcam'
DeviceIDs: {1x0 cell}
DeviceInfo: [1x0 struct]
When I want to try out this code: http://www.mathworks.com/matlabcentral/fileexchange/28757-tracking-red-color-objects-using-matlab
I get the error:
Error using videoinput (line 188) The DEVICEID is not a valid identifier. See IMAQHWINFO(ADAPTORNAME).
Error in redObjectTrack (line 7) vid = videoinput(camera_name, camera_id, format);
because the code use winvideo or other driver...I put in the the *getCameraInfo function manualy the paramters. Like this:
function [camera_name, camera_id, resolution] = getCameraInfo(a) info = imaqhwinfo info2 = imaqhwinfo('dcam') camera_name = 'dcam' % camera_info = info2.DeviceInfo camera_info = {[1]} camera_id = {[1]} resolution = { 'YUY2_320x240' }
