为什么我第一次识别红色成功后第二次再识别屏幕的色彩变绿了好多
-
对啊你可以吧他删了也可以
-
你给我一个可以运行出故障的代码。

我需要怎么操作才能出现“我第一次识别红色成功后第二次再识别屏幕的色彩变绿了好多”的现象？
-
sensor初始化应该放在一开始，而不应该循环重新设置。
sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time = 2000) sensor.set_auto_gain(False) sensor.set_auto_whitebal(False) sensor.set_auto_exposure(False, 1500)#这里设置曝光时间
-
@kidswong999 就放在fun这函数外面是吗
-
放在最开始，也就是import下面
-
@kidswong999 但是在while想改对于的参数呢
-
改参数和sensor初始化有什么关系？
-
@kidswong999 第一次识别到红色，然后继续识别图像以及卡主了
-
@13542749802 是不是需要重新初始化啊，我重新初始化就不会
-
和初始化没关系。感光元件只需要开机初始化一次。
-
@kidswong999 那为什么识别到红色，图像就停止了呢
-
@13542749802 你要提供你的代码。
