光源扩展板和拍照代码共同运行会出现卡顿,有没有什么改进方法?代码如下
-
import sensor, image, time
import time
from pyb import Pin, Timerlight = Timer(2, freq=50000).channel(1, Timer.PWM, pin=Pin("P6"))
light.pulse_width_percent(10) # 控制亮度 0~100
sensor.reset() # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA) # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000) # Wait for settings take effect.
clock = time.clock() # Create a clock object to track the FPS.while(True):
time.sleep_ms(200)
clock.tick() # Update the FPS clock.
img = sensor.snapshot() # Take a picture and return the image.
print(clock.fps()) # Note: OpenMV Cam runs about half as fast when connected
# to the IDE. The FPS should increase once disconnected.

卡顿是因为你在死循环里time.sleep_ms(200),删了就行。
