# 深度工作模式示例-DepthWorkMode

支持的设备： Gemini 330系列，Gemini 2系列相机，Astra 2系列相机

功能描述：演示转换深度工作模式操作。

>本示例基于C++ High Level API进行演示

创建Pipeline, 获取设备

// Create a pipeline with default device
ob::Pipeline pipe;

// Get the device inside the pipeline
auto device = pipe.getDevice();

检查是否支持工作模式转换

// Check whether the camera depth working mode is supported, currently (December 5, 2022) only the Gemini2 binocular camera supports the depth working mode
if(!device->isPropertySupported(OB_STRUCT_CURRENT_DEPTH_ALG_MODE, OB_PERMISSION_READ_WRITE)) {
    pressKeyExit("Current device not support depth work mode!");
    return -1;
}

获取深度工作模式列表

// Query the current camera depth mode
auto curDepthMode = device->getCurrentDepthWorkMode();
// Get the list of camera depth modes
auto depthModeList = device->getDepthWorkModeList();
std::cout << "depthModeList size: " << depthModeList->count() << std::endl;
for(uint32_t i = 0; i < depthModeList->count(); i++) {
    std::cout << "depthModeList[" << i << "]: " << (*depthModeList)[i];
    if(strcmp(curDepthMode.name, (*depthModeList)[i].name) == 0) {
        std::cout << "  (Current WorkMode)";
    }

    std::cout << std::endl;
}

设置深度工作模式

// Let the user choose a mode, then switch
if(depthModeList->count() > 0) {
    uint32_t index = 0;
    std::cout << "Please input the index from above depthModeList, newIndex = ";
    std::cin >> index;
    if(index >= 0 && index < depthModeList->count()) {  // legitimacy check
        device->switchDepthWorkMode((*depthModeList)[index].name);

        // Check whether the mode changes after the display is switched
        curDepthMode = device->getCurrentDepthWorkMode();
        if(strcmp(curDepthMode.name, (*depthModeList)[index].name) == 0) {
            std::cout << "Switch depth work mode success! currentDepthMode: " << curDepthMode << std::endl;
        }
        else {
            std::cout << "Switch depth work mode failed!" << std::endl;
        }
    }
    else {
        std::cout << "switchDepthMode faild. invalid index: " << index << std::endl;
    }
}
