# 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 import time import pyb sensor.reset() sensor.set_pixformat(sensor.RGB565) # 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())
