我只是使用测距拓展板，看看TOF的准确度怎么样，为什么老是报这个错误，连接是没有问题的，先是有数据然后就报错

from machine import I2C
from vl53l1x import VL53L1X
import time

i2c = I2C(2)
distance = VL53L1X(i2c)

while True:
    print("range: mm ", distance.read())
    time.sleep_ms(50)

我的是OPENMV4PLUS，想寻电线，使用VGA像素，为什么找出的是线段这个样子，哪里做的不对

def Line_Find_Fit(img):
    for l in img.find_lines(roi=Middle_Roi, threshold=800, y_stride=20, theta_margin=10, rho_margin=10):
        if ((l.theta() >= min_degree) and (l.theta() <= max_degree)):#and (l.length() >= 20)
            img.draw_line(l.line(), color = (255, 0, 0))
            best_line = l
            PoleAndLine.Line_flag = 1
            PoleAndLine.Line_y = (best_line.y1() + best_line.y2())/2
            print(PoleAndLine.Line_y)
            return best_line
        else:
            PoleAndLine.Line_flag = 0

@kidswong999 可能好一点了，但还是感觉偏暗

下面是用手机拍的

@kidswong999 是硬件的问题吗

@kidswong999

@kidswong999 跑例程就是这样的效果

# Hello World Example
#
# Welcome to the OpenMV IDE! Click on the green run arrow button below to run the script!

import sensor, image, time

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):
    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
               

感觉过头了，白天好一些，色块经常都不灵，openmv4就感觉还正常



实际灯挺亮的
下面是openmv4的图像

代码里面白平衡，曝光什么的也开了，没什么效果
plus就这样的吗，还是我哪里做的不对
