lecture depuis camera avec dc1394

mon probleme quand je compile le grogramme il connait pas fonction de bibliotheque comme (dc1394_cameracapture camera; raw1394handle_t handle; nodeid_t * camera_nodes) merci ------------------------- #include #include #include #include #include #define IMAGE_FILE_NAME "image" #define IMAGE_FILE_EXT ".pgm" void write_pgm(char *path, unsigned char *image_lum, int H, int W) { FILE *input=fopen(path,"wb"); if(!input) { printf("Can't open file %s\n",path); exit(1); } fprintf(input, "P5\n%d %d 255\n", W, H); fwrite(image_lum,1, H*W ,input); fclose(input); } dc1394_cameracapture camera; raw1394handle_t handle; nodeid_t * camera_nodes; void setup_camera() { int numNodes; int numCameras; /* Open ohci and asign handle to it */ handle = dc1394_create_handle(0); if (handle==NULL) { fprintf( stderr, "Unable to aquire a raw1394 handle\n\n" ); exit(1); } /* get the camera nodes and describe them as we find them */ numNodes = raw1394_get_nodecount(handle); camera_nodes = dc1394_get_camera_nodes(handle,&numCameras,1); fflush(stdout); if (numCameras<1) { fprintf( stderr, "no cameras found :(\n"); dc1394_destroy_handle(handle); exit(1); } printf("working with the first camera on the bus\n"); if( camera_nodes[0] == numNodes-1) { fprintf( stderr, "\n" "Sorry, your camera is the highest numbered node\n"); dc1394_destroy_handle(handle); dc1394_free_camera_nodes(camera_nodes); exit( 1); } /*setup capture */ if (dc1394_dma_setup_capture(handle, camera_nodes[0], 0, /*channel*/ FORMAT_VGA_NONCOMPRESSED, MODE_640x480_MONO, SPEED_400, FRAMERATE_30, 8, 1, NULL, &camera) != DC1394_SUCCESS) { fprintf( stderr,"unable to setup camera-\n" "check line %d of %s to make sure\n" "that the video mode,framerate and format are\n" "supported by your camera\n", __LINE__,__FILE__); dc1394_release_camera(handle,&camera); dc1394_destroy_handle(handle); dc1394_free_camera_nodes(camera_nodes); exit(1); } /* have the camera start sending us data*/ if (dc1394_start_iso_transmission(handle,camera.node) !=DC1394_SUCCESS) { fprintf( stderr, "unable to start camera iso transmission\n"); dc1394_release_camera(handle,&camera); dc1394_destroy_handle(handle); exit(1); } } void stop_camera() { if (dc1394_stop_iso_transmission(handle,camera.node)!=DC1394_SUCCESS) printf("couldn't stop the camera?\n"); /* Close camera */ dc1394_release_camera(handle,&camera); dc1394_destroy_handle(handle); } int main(int argc, char *argv[]) { FILE* imagefile; quadlet_t myq; /* d'abord initialiser la camera */ setup_camera(); char name[20]; char strnum[5]; int k; unsigned char * image; /* capturer quelques frames */ for(k = 1; k < 5; k++) { dc1394_dma_single_capture(&camera); //strcpy(name,argv[1]); strcpy(name,IMAGE_FILE_NAME); sprintf(strnum,"%04d",k); strcat(name,strnum); strcat(name,IMAGE_FILE_EXT); printf("%s\n",name); /* (unsigned char *)camera.capture_buffer est un pointer vers l'image * qu'on a capture */ write_pgm(name,(unsigned char *)camera.capture_buffer,480,640); image = (unsigned char *)camera.capture_buffer; /* toujours liberer la frame quand on n'en a plus besoin */ dc1394_dma_done_with_buffer(&camera); } /*stopper et desalouer la camera */ stop_camera(); return 0; }
