C 示例代码-Hello Orbbec

# 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

 

首先获取并打印当前SDK版本

printf("SDK version: %d.%d.%d\n", ob_get_major_version(), ob_get_minor_version(), ob_get_patch_version());

 

创建一个Context,用于获取设备信息列表和创建设备

ob_error*   error = NULL;
ob_context* ctx   = ob_create_context( &error );

 

查询已经接入设备的列表,从而获取列表内设备数量,并通过索引号0创建获取列表内第一个设备

ob_device_list* dev_list = ob_query_device_list( ctx, &error );
int dev_count = ob_device_list_device_count(dev_list, &error);
if(dev_count == 0) {
    printf("Device not found!\n");
    return -1;
}
ob_device* dev = ob_device_list_get_device(dev_list, 0, &error);

 

接下来就可以获取和这个设备相关的信息了

//获取设备信息
ob_device_info* dev_info = ob_device_get_device_info(dev, &error);

//获取设备名称
const char* name = ob_device_info_name(dev_info, &error);

//获取设备的pid, vid, uid
int pid = ob_device_info_pid(dev_info, &error);
int vid = ob_device_info_vid(dev_info, &error);
int uid = ob_device_info_uid(dev_info, &error);

//通过获取设备的固件版本号
const char* fw_ver = ob_device_info_firmware_version(dev_info, &error);

//通过获取设备的序列号
const char* sn = ob_device_info_serial_number(dev_info, &error);

//获取支持的传感器列表
ob_sensor_list* sensor_list = ob_device_get_sensor_list(dev, &error);

//获取传感器数量
int count = ob_sensor_list_get_sensor_count(sensor_list, &error);
for(int i = 0; i < count; i++)
{
    ob_sensor_type sensor_type = ob_sensor_list_get_sensor_type(sensor_list, i, &error);
    switch (sensor_type)
    {
      case OB_SENSOR_COLOR:
          break;
        case OB_SENSOR_DEPTH:
          break;
        case OB_SENSOR_IR:
          break;
    }
}

 

释放资源,退出程序。

//销毁sensor list
ob_delete_sensor_list(sensor_list, &error);
//销毁device info
ob_delete_device_info(dev_info, &error);
//销毁device
ob_delete_device(dev, &error);
//销毁device list
ob_delete_device_list(dev_list, &error);
//销毁context
ob_delete_context(ctx, &error);
