Hello,
with the purpose of being able to track elements in sight of a cam by virtue of their color, I would like to use and explore the possibilities of pdp_ctrack. While this does work with prerecorded video (avi) i am unable to try it with live video, cause pdp_v4l gives and error. See below what happens when trying to send [open /dev/video0< to [pdp_v4l].
pdp_v4l: opening /dev/video0 pdp_v4l: cap: name UVC Camera (046d:0802) type 1 channels 1 maxw 640 maxh 480 minw 48 minh 32 pdp_v4l: picture: brightness 32896 depth 0 palette 0 pdp_v4l: channel 0 name Camera 1 type 2 flags 0 pdp_v4l: switched to channel 0 pdp_v4l: cant change to norm 0 error: pdp_v4l: no method for 'type'
Does anyone know if this is a matter of buying a better cam? Now using a Logitech very simple usb webcam. Or do i need to load/install a certain driver, or send other messages to [pdp_v4l]? My purpose is to get coordinates (and possibly size) of colored elements. I want to be able to track different elements simultaneously, and be able to calculate distance. Maybe a combination with size would also allow me to calculate distance in 3 dimension. Then to use the data for conditional sounds (tonal and/or atonal). Any help appreciated!
Bye, Menno.
