创建您的第一个相机利用
这个急剧入门将援手你急剧使用Orbbec SDK，，，，，构建你的第一个相机利用法式必要用到以下函数：
queryDeviceList()
deviceCount()
getDevice()
getDeviceInfo()
firmwareVersion()
serialNumber()
connectionType()
getSensorList()
getSensor()
先决前提
衔接Orbbec设备。 。。。。。。。
下载并装置Orbbec SDK。 。。。。。。。
头文件
蕴含Orbbec SDK的重要头文件
```cpp
#include <iostream>
#include "utils.hpp"
#include "libobsensor/ObSensor.hpp"
#include "libobsensor/hpp/Error.hpp"
```
查找Orbbec设备
首先，，，，，我们必要查抄您的推算机衔接了几多个Orbbec设备。 。。。。。。。使用函数来检索衔接的设备。 。。。。。。。
// Create a Context.
ob::Context ctx;
// Query the list of connected devices
auto devList = ctx.queryDeviceList();
if (devList->deviceCount() == 0) {
std::cerr << "Device not found!" << std::endl;
return -1;
}
若是检测到设备，，，，，您能够持续接见其信息和传感器。 。。。。。。。
接见设备信息
获取设备列表后，，，，，打开第一个设备并检索一些根基信息，，，，，好比设备名称和固件版本。 。。。。。。。
auto dev = devList->getDevice(0);
auto devInfo = dev->getDeviceInfo();
std::cout << "Device name: " << devInfo->name() << std::endl;
std::cout << "Firmware version: " << devInfo->firmwareVersion() << std::endl;
// By getting the serial number of the device
auto sn = devInfo->serialNumber();
std::cout << "Serial number: " << sn << std::endl;
// By getting the connection type of the device
auto connectType = devInfo->connectionType();
std::cout << "ConnectionType: " << connectType << std::endl;
列出传感器
接下来，，，，，通过获取传感器列表并打印每个传感器类型。 。。。。。。。
// Get the list of supported sensors
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;
}
}
谬误处置
在你的利用法式中蕴含谬误处置是很沉要的。 。。。。。。。Orbbec SDK提供了具体的异常，，，，，能够捕获以相识在执行过程中产生了什么谬误。 。。。。。。。
```cpp
catch(ob::Error &e) {
std::cerr << "Error: " << e.getMessage() << std::endl;
return -2;
}
```
