Hi. I have follow your suggestion but I still can't display any blob on playerv.And when I change camerav4l mode from "YUV420P" to "RGB24" the server display: fg_grab(): failed to capture frame: Invalid argument. How can test blobfinder? Can you send your config file to me? Note:My camera haven't any problem.I can display image by videoplayer program. Thank you. --- Nils Ole Tippenhauer <no...@gm...> wrote: > Here's what I did to get the blobfinder to work: > > 1) add a cameracompress driver to the player server > 2) view the stream from this camera interace with > the videoplayer > software from the 3rd party section on the player > website > 3) capture a camera picture from that program, turn > it into YUV (I used > Gimp+ a plugin for that) > 4) measure the YUV values of the object in the > converted picture and > estimate if its different enough from its > environment > 5) write those values in the color.txt (its YUV at > the thresholds) > > then it worked for me, took ages and some source > code reading to find > out that the thresholds are in YUV > > > hope that helps > > Ole > -- > Nils Ole Tippenhauer > Exchange research student > PAMI lab, University of Waterloo > pami.uwaterloo.ca > > > > Thanomsak Agganapanya wrote: > > Hi > > I trying to use CMVision driver for detect > yellow > > object.I place yellow object in front of my > logitech > > quickcam.When I run playerv and subscribe > blobfinder I > > can't see anything on playerv window. what happen? > > > Here is my config file: > > driver > > ( > > name "camerav4l" > > provides ["camera:0"] > > port "/dev/video1" > > size [320 240] > > mode "YUV420P" > > source 0 > > ) > > driver > > ( > > name "cmvision" > > provides ["blobfinder:0"] > > requires ["camera:0"] > > colorfile ["color.txt"] > > ) > > And this is my color.txt: > > [Colors] > > (00,00,00) 0.000000 'Yellow' > > [Thresholds] > > (170:200,185:220,85:115) > > > > > > > > > > > ____________________________________________________ > > Start your day with Yahoo! - make it your home > page > > http://www.yahoo.com/r/hs > > > > > > > > > ------------------------------------------------------- > > SF.Net email is sponsored by: Discover Easy Linux > Migration Strategies > > from IBM.
