追踪色块程序关掉白平衡后,开盖启动程序时随机出现三种不同的色调
-
import sensor, image, time color_lab=[(4, 27, -13, 9, -8, 11)]#black sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QVGA) sensor.skip_frames(time = 2000) sensor.set_auto_gain(False) sensor.set_auto_whitebal(False) clock = time.clock() while(True): clock.tick() img = sensor.snapshot().lens_corr(strengh=1.8,zoom=1.0) for blob in img.find_blobs(color_lab,merge=True,area_threshold=200,pixel_threshold=1000): img.draw_rectangle(blob.rect())#draw a rectangle img.draw_cross(blob.cx(),blob.cy()) print(blob.code())
请在这里粘贴代码

sensor.set_auto_whitebal(False),要添加第二个参数的。

同理,sensor.set_auto_gain你也得改。
