Hello, I'm working with Player/Stage for two weeks, and I've started with simple example, Wander, Avoid Obstacle with sonar... I'm working with versions: Player 2.1.2 y Stage 2.1.0. Last days I was testing some examples from Jennifer Owen' tutorial "How to Use Player/Stage" and others, and I'm getting trouble with Blobfinder. I don't know why this element doesn't work. I was testing with c++ example from Jennifer Owen' tutorial, making changes recommended for older versions, and robot was unable to view any colors. I was using "playerv" for view what the robot was sensing by blobfinder, and it doesn't detect anything. Also, I was testing with java client example and I could confirm that blobfinder doesn't work. In the example, three object with three different colors was in the map, and robot should detect this object using blobfinder. I think this is a bug for blobfinder, for the versions I'm using. However, I'm going to write the section in cfg and inc files for two example: Jennifer Owen' tutorial Example Robot INC file: define p3at_eyes ptz ( blobfinder ( # Número de colores que deteca la cámara channel_count 2 # Color que detecta la cámara Channels [ "orange" "red" ] # Parámetros de la cámara image [260 220] #Resolución range_max 10.00 ) ptz [0 0 160] ) And then in the same file p3at_eyes() CFG file: driver ( name "stage" provides [ "position2d:0" "sonar:0" "blobfinder:0"] model "r0" ) Example for Java Cliente CFG file: driver ( name "stage" provides ["position2d:0" "blobfinder:0" "sonar:0" ] model "robot1" ) WORLD file: # create a robot pioneer2dx ( name "robot1" color "red" pose [0 -5 0] ptz ( ptz [0 0 180.0] blobfinder ( channel_count 3 channels [ "red" "green" "blue" ] range_max 5 ) ) ) Can anyone help me????? Thank you in advance. |
