# 流对齐处理单元-AlignFilterViewer
支持设备: Gemini 330系列相机,例如:Gemini G335
功能描述:演示传感器数据流同步对齐的操作,显示对齐后的图像,并通过ESC_KEY键退出程序
>本示例基于C++ hign Level API进行演示
创建pipeline
ob::Pipeline pipe;
开启color流
auto colorProfiles = pipe.getStreamProfileList(OB_SENSOR_COLOR);
if(colorProfiles) {
colorProfile = colorProfiles->getVideoStreamProfile(1280, OB_HEIGHT_ANY, OB_FORMAT_RGB, 30);
}
config->enableStream(colorProfile);
开启深度流
auto depthProfiles = pipe.getStreamProfileList(OB_SENSOR_DEPTH);
std::shared_ptr
if(depthProfiles) {
depthProfile = depthProfiles->getVideoStreamProfile(640, OB_HEIGHT_ANY, OB_FORMAT_Y16, 30);
//depthProfile = std::const_pointer_cast
}
config->enableStream(depthProfile);
设置对齐模式
/* Config depth align to color or color align to depth.
OBStreamType align_to_stream = OB_STREAM_DEPTH; */
OBStreamType align_to_stream = OB_STREAM_COLOR;
ob::Align align(align_to_stream);
开启pipeline
pipe.start(config);
获取帧数据
auto colorFrame = frameSet->colorFrame();
auto depthFrame = frameSet->depthFrame();
进行对齐处理
aif(align_to_stream == OB_STREAM_COLOR) {
app.resize(colorFrame->width(), colorFrame->height());
}
else {
app.resize(depthFrame->width(), depthFrame->height());
}
关闭pipeline
pipe.stop();
