detect xy-position of points in a picture

stonebiter User Web-site Posted: 08 Aug 2006 18:59 • Complain to moderator   • User info Can I use VisionLab to determine the xy-coordinates of good visible points (red points) on a surface of about 1m x1m ? Reference-points for x0, y0 and xmax, ymax could be positioned on the surface . There is no movement but a desired accuracy of 1mm . I never worked with picture recognition nor video capturing before - so I'm probably wrong here ?. Thanks Harald

I just discovered that there ware postings unanswered :-( . i know I should have checked earlier. I am not sure what you mean by this one. You can work with individual pixels in VisionLab. You can use the TVLGenericFilter for that. Please e-mail me at mitov@mitov.com for details if you have problems. With best regards, Boian Mitov
