# Keypoints Drawing # # This example shows off drawing keypoints on the OpenMV Cam. Usually you call draw_keypoints() # on a keypoints object but you can also call it on a list of 3-value tuples... import sensor, image, time, pyb sensor.reset() sensor.set_pixformat(sensor.GRAYSCALE) # or GRAYSCALE... sensor.set_framesize(sensor.QVGA) # or QQVGA... sensor.skip_frames(time = 2000) clock = time.clock() while(True): clock.tick() img = sensor.snapshot() for i in range(20): x = (pyb.rng() % (2*img.width())) - (img.width()//2) y = (pyb.rng() % (2*img.height())) - (img.height()//2) rot = pyb.rng() % 360 r = (pyb.rng() % 127) + 128 g = (pyb.rng() % 127) + 128 b = (pyb.rng() % 127) + 128 # This method draws a keypoints object or a list of (x, y, rot) tuples... img.draw_keypoints([(x, y, rot)], color = (r, g, b), size = 20, thickness = 2, fill = False) print(clock.fps())
