有谁知道如何在 IDS 相机上正确配置 Mono12 模式?
我尝试了 is_SetColorMode 方法,将每像素的 BITES 设置为 12,将每像素的 BYTES 设置为 2,依此类推。它不能那么好。
最后,我在 IDS uEye Cockpit 中完成了一个配置文件,保存了它,现在用于在 python 代码的开头设置相机。它也没有帮助。
我现在遇到的问题是我得到的图像是在两个~2056*2056(芯片大小)的数组中引入的。发生这种情况是因为我每个像素有 2 个字节。但我不知道如何将其正确转换为正常图像。
此外,即使在默认的 Mono8 模式下,我看到的图片也与我在 IDS 应用程序中看到的不同。
这是代码(我也可以给出配置文件):
