我也没有训练啥网络，就是用着用着打不开了

在user里面也找不到openmv文件夹，自己创建一个之后安装里面也没有东西，每次都是打开这个页面就闪退

这个返回的line_all值到底是什么？

,这个权重到底影响的是啥？

@kidswong999 就是这样写和我们从阈值编辑器里复制过来的区别和各个功能

这样写和直接从阈值编辑器复制过来有啥区别？

red_threshold_LAB=(29, 76, -21, 78, 7, 66)#in LAB color space for finding blobs在LAB颜色空间中寻找斑点
green_threshold_LAB=(50,80,-50,-30,-10,10)
red_threshold_RGB= (200,256,0,150,0,150)  #in RGB color space for finding edges
green_threshold_RGB=(-1,70,80,256,60,256)

由于该设备有问题，Windows 已将其停止。 (代码 43)

我也想知道，插个眼

机器人巡线里的例子

跟踪一条黑线。使用[(128,255)]来跟踪白线。

GRAYSCALE_THRESHOLD = [(0, 64)]
#设置阈值，如果是黑线，GRAYSCALE_THRESHOLD = [(0, 64)]；
#如果是白线，GRAYSCALE_THRESHOLD = [(128，255)]
这个是巡线小车的，

sensor.reset()
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framesize(sensor.QQVGA)
sensor.skip_frames(time=2000)
sensor.set_auto_gain(False)  # must be turned off for color tracking
sensor.set_auto_whitebal(False)  # must be turned off for color tracking
clock = time.clock()

这个设置中

threshold = [53, 238]

阈值为啥设置成这样，
为啥阈值是两个值，改变这两个值对灰色有啥影响吗？

@kidswong999 协议没啥标准，就是串口通信，有时候算法组合起来不知道怎么发送数据给飞控

@scdg 太难了，有的地方就感觉不知道咋写了

如何发角度值给飞控，和如何判断
