What if you use my panel.jpg, it's 640x480Sorry gordon77's example code gives me errors - I must have done it wrong, copied OP's LED jpg to panel.jpg:Code:
/usr/lib/python3/dist-packages/numpy/lib/function_base.py:518: RuntimeWarning: Mean of empty slice. avg = a.mean(axis, **keepdims_kw)/usr/lib/python3/dist-packages/numpy/core/_methods.py:192: RuntimeWarning: invalid value encountered in scalar divide ret = ret.dtype.type(ret / rcount)Traceback (most recent call last): File "/home/pi/my_project/g77-opencv.txt", line 182, in <module> cv2.putText(img,str(int(average)), (points[box+1] + 130, points[box] + 10 ), cv2.FONT_HERSHEY_SIMPLEX, 0.4, (100, 100, 100),1)ValueError: cannot convert float NaN to integer
I found the panel uses red, amber and green leds so working on an updated version...
