# HelloOrbbec

功能描述：用于演示SDK初始化、获取SDK版本、获取设备型号、获取设备序列号、获取固件版本号、SDK释放资源，并通过ESC_KEY键退出程序

> 本示例基于C++ Low Level API进行演示

打印SDK的版本号，SDK版本号分为主版本号，副版本号和修订版本号

std::cout << "SDK version: " << ob::Version::getMajor() << "." << ob::Version::getMinor() << "." << ob::Version::getPatch() << std::endl;

首先需要创建一个Context，用于获取设备信息列表和创建设备

ob::Context ctx;

查询已经接入设备的列表

auto devList = ctx.queryDeviceList();

//获取接入设备的数量
if(devList->deviceCount() == 0) {
    std::cerr << "Device not found!" << std::endl;
    return -1;
}

创建设备

//创建设备，0表示第一个设备的索引
auto dev = devList->getDevice(0);

获取当前preset信息

auto devicePresetList = dev->getAvailablePresetList();
auto devicePreset     = dev->getCurrentPresetName();
std::cout << "Available preset list: " << std::endl;
for(uint32_t i = 0; i < devicePresetList->count(); i++) {
    auto name = devicePresetList->getName(i);
    if(std::string(name) == std::string(devicePreset)) {
        std::cout << "\t" << name << " (current preset)" << std::endl;
    }
    else {
        std::cout << "\t" << name << std::endl;
    }

设置当前preset

auto newPreset = "High Accuracy";
if(devicePresetList->hasPreset(newPreset)) {
    dev->loadPreset(newPreset);
    std::cout << "Current preset is changed to " << newPreset << std::endl;
}

接下来就可以获取和这个设备相关的信息：设备信息、设备的名称、获取设备的pid, vid, uid、设备的固件版本号、设备的序列号

//获取设备信息
auto devInfo = dev->getDeviceInfo();

//获取设备的名称
std::cout << "Device name: " << devInfo->name() << std::endl;

//获取设备的pid, vid, uid
std::cout << "Device pid: " << devInfo->pid() << " vid: " << devInfo->vid() << " uid: " << devInfo->uid() << std::endl;

//获取设备的固件版本号
auto fwVer = devInfo->firmwareVersion();
std::cout << "Firmware version: " << fwVer << std::endl;

//获取设备的序列号
auto sn = devInfo->serialNumber();
std::cout << "Serial number: " << sn << std::endl;

// By getting the connection type of the device
auto connectType = devInfo->connectionType();

获取支持的传感器列表

//获取支持的传感器列表
std::cout << "Sensor types: " << std::endl;
auto sensorList = dev->getSensorList();
for(uint32_t i = 0; i < sensorList->count(); i++) {
    auto sensor = sensorList->getSensor(i);
    switch(sensor->type()) {
    case OB_SENSOR_COLOR:
        std::cout << "\tColor sensor" << std::endl;
        break;
    case OB_SENSOR_DEPTH:
        std::cout << "\tDepth sensor" << std::endl;
        break;
    case OB_SENSOR_IR:
        std::cout << "\tIR sensor" << std::endl;
        break;
    case OB_SENSOR_IR_LEFT:
        std::cout << "\tIR Left sensor" << std::endl;
        break;
    case OB_SENSOR_IR_RIGHT:
        std::cout << "\tIR Right sensor" << std::endl;
        break;
    case OB_SENSOR_GYRO:
        std::cout << "\tGyro sensor" << std::endl;
        break;
    case OB_SENSOR_ACCEL:
        std::cout << "\tAccel sensor" << std::endl;
        break;
    default:
        break;
    }

控制台结果输出如下：
