Provided are an apparatus and a method capable of verifying at high frequency whether a sensor is capable of calculating a normal distance and capable of implementing high-frequency sensor calibration. The apparatus calculates a distance between a host vehicle and an external vehicle or a distance between the host vehicle and an infrastructure as distance data D1 calculated by the host device based on a detection value of a sensor such as a stereo camera, receives a distance between devices calculated by the external device as distance data D2 calculated by the external device from the external device, and transmits the received distance data D2 to the host device. The distance data D1 calculated by the device is compared with the distance data D2 calculated by the external device, and whether the sensor can measure the correct distance value is determined based on the comparison result. If it is determined that the sensor cannot measure the correct distance value, a sensor calibration process or a fault detection process is performed.
提供了一种能够高频率地验证传感器是否能够计算正常距离并且能够实现高频传感器校准的设备和方法。所述设备基于诸如立体相机之类的传感器的检测值计算本车与外部车辆之间的距离或者本车与基础设施之间的距离作为本设备计算的距离数据D1,从外部设备接收由外部设备计算的设备之间的距离作为外部设备计算的距离数据D2,将本设备计算的距离数据D1与外部设备计算的距离数据D2进行比较,并且基于比较结果确定传感器是否能够测量出正确距离值。如果确定传感器不能够测量出正确距离值,则执行传感器校准处理或故障检测处理。
