或者使用现有过滤器的方法？这样你就可以从鱼眼镜头或双鱼眼镜头(如理光Theta)中获取视频,并直接将equirectangular实时输出到像RTMP这样的东西？

我使用开放框架将双鱼眼视频(从ricoh theta S相机接收)转换为equirectangular格式(适用于iOS应用程序).

双鱼眼图像样本:

equirectangular图像样本:

我使用下面的着色器:

    vec2 revUV = texCoordVarying.st;
    if (texCoordVarying.x <= 0.5) {
        revUV.x = revUV.x * 2.0;
    } else {
        revUV.x = (revUV.x - 0.5) * 2.0;
    }

    revUV *= …
