我试图通过 Kinect 深度相机隔离单个玩家。我正在打开一个NUI_IMAGE_TYPE_DEPTH_AND_PLAYER_INDEX
流来处理播放器/深度信息。我用来绘制玩家的代码是这样的:
if (LockedRect.Pitch != 0 ) {
USHORT* curr = (USHORT*) LockedRect.pBits;
const USHORT* dataEnd = curr + ((width/2)*(height/2));
index = 0;
while (curr < dataEnd && playerId != 0) {
USHORT depth = *curr;
USHORT realDepth = NuiDepthPixelToDepth(depth);
BYTE intensity = 255;
USHORT player = NuiDepthPixelToPlayerIndex(depth);
// Only colour in the player
if (player == playerId) {
for (int i = index; i < index + 4; i++)
dest[i] = intensity;
}
else {
for (int i = index; i < index + 4; i++)
dest[i] = 0;
}
index += 4;
curr += 1;
}
}
dest
是一个 OpenGL 纹理。
我遇到的问题是player
当第二个人进入框架时变量会发生变化,并导致在纹理中绘制的人成为新人。
