10 | | - |
11 | | -- **Recording count**变量的框设置为数值1，因为我们每次只需拍一张图片，用作python程序的输入来处理图片。 |
12 | | - |
13 | | -- 点击**Start**开始拍照，拍照的流程如下： |
14 | | - - 判断是否启动相机实例，只有存在实例的情况下进入`while`循环，进行照片的获取、记录和保存。 |
15 | | - - 在`while`循环中，首先判断相机是否已经在记录当中且已经记录了至少一张图片，如果为真的话则停止记录，清除缓存，再打开相机记录；为假的话则直接打开相机记录。 |
16 | | - - 接着延迟200ms，处理所有的当前在消息队列中的Windows消息。 |
17 | | - - 再次判断相机是否已经在记录或者至少记录了一张图片，为真时进入以下流程：从缓冲区获取已记录的照片的列表，将照片保留，清除缓存，释放已分配内存。 |
18 | | - - 接着再一次停止记录，关掉图片获取，打开图片获取（此时已执行完`while`循环内的内容）。 |
19 | | - |
20 | | -- 由于每次存的图片命名是相同的，每次新图片会强制覆盖旧图片，而机械臂收回到相机范围外停留时间远大于每次拍照时间，所以python处理的最新图片不会有机械臂的影响 |
