Question

我需要对每个原始帧进行一些处理并将其显示在预览中。这是我正在使用的代码（在Kotlin中）：

                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

我最终得到了一个奇怪的带有很多绿色像素的rgb框架。

根据文档，原始图像（通过ImageFormat.RAW_SENSOR）是16位单通道，多位。我可能会丢失一些东西，因为仅在CV_16UC1垫中分配字节缓冲区并将其转换为RGB不起作用。另外，即使对于线性色彩空间，最终的框架似乎也太暗。我将不胜感激！

有不同的拜耳样式布局，并且不知道相机的布局，我想您错了。 Opencv通过左上角的前两种颜色对其进行引用：cv::COLOR_Bayer BG 2BGR

在opencv中，使用不同的标志来支持这些标志：

cv::COLOR_BayerRG2BGR
cv::COLOR_BayerGR2BGR
cv::COLOR_BayerGB2RGB

...等完整列表可在此处找到：https://docs.opencv.org/3.1.0/de/d25/imgproc_color_conversions.html

您可以尝试研究平台的Bayer布局，也可以尝试直到它起作用。祝你好运！

如何使用OpenCV在Android中将原始图像转换为RGB？
