例程讲解99-Tests->fps帧率测试

# 帧率测试例程
import sensor, image, time

sensor.reset() # Initialize the camera sensor.
sensor.set_framesize(sensor.QQVGA) # or sensor.QQVGA (or others)
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_colorbar(True)   # 启用颜色条输出

clock = time.clock() # Tracks FPS.
for i in range(0, 600):
    clock.tick() # Track elapsed milliseconds between snapshots().
    sensor.snapshot() # Capture snapshot.

print("FPS:", clock.fps())
