Blob Detection and uart transport
import sensor, image, time
from pyb import UART
import jsonFor color tracking to work really well you should ideally be in a very, very,
very, controlled enviroment where the lighting is constant...
#red_threshold = (32, 77, -69, 96, 19, 64)
#green_threshold = (9, 100, -22, -83, 11, 125)
#blue_threshold = (27, 95, -43, 18, -7, -72)red_threshold = (96, 12, 26, 103, 64, -114)
green_threshold = (100, 3, -13, -66, 49, -29)
blue_threshold = (100, 0, 70, -80, -65, -4)You may need to tweak the above settings for tracking green things...
Select an area in the Framebuffer to copy the color settings.

我运行这个代码没有出现错误。
请提供你的OpenMV硬件版本,固件版本,和IDE的版本。

只是有时会出现报错,有时不会
硬件是Openmv m3
