# HelloOrbbec

功能描述：用于演示SDK初始化、獲取SDK版本、獲取設備型號、獲取設備序列號、獲取固件版本號、SDK釋放資源，并通過(guò)ESC_KEY鍵退出程序

> 本示例基于C++ Low Level API進(jìn)行演示

打印SDK的版本號，SDK版本號分為主版本號，副版本號和修訂版本號

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

首先需要創(chuàng )建一個(gè)Context，用于獲取設備信息列表和創(chuàng )建設備

ob::Context ctx;

查詢(xún)已經(jīng)接入設備的列表

auto devList = ctx.queryDeviceList();

//獲取接入設備的數量
if(devList->deviceCount() == 0) {
    std::cerr << "Device not found!" << std::endl;
    return -1;
}

創(chuàng )建設備

//創(chuàng )建設備，0表示第一個(gè)設備的索引
auto dev = devList->getDevice(0);

獲取當前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;
    }

設置當前preset

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

接下來(lái)就可以獲取和這個(gè)設備相關(guān)的信息：設備信息、設備的名稱(chēng)、獲取設備的pid, vid, uid、設備的固件版本號、設備的序列號

//獲取設備信息
auto devInfo = dev->getDeviceInfo();

//獲取設備的名稱(chēng)
std::cout << "Device name: " << devInfo->name() << std::endl;

//獲取設備的pid, vid, uid
std::cout << "Device pid: " << devInfo->pid() << " vid: " << devInfo->vid() << " uid: " << devInfo->uid() << std::endl;

//獲取設備的固件版本號
auto fwVer = devInfo->firmwareVersion();
std::cout << "Firmware version: " << fwVer << std::endl;

//獲取設備的序列號
auto sn = devInfo->serialNumber();
std::cout << "Serial number: " << sn << std::endl;

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

獲取支持的傳感器列表

//獲取支持的傳感器列表
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;
    }
