Abstract
Provided is a lidar device for a vehicle including an optical transmitter configured to transmit an outgoing optical signal, an optical receiver configured to receive a plurality of return optical signals incident in different directions, at least one temperature sensor configured to identify a temperature of the lidar device, and a processor operatively coupled with the optical transmitter, the optical receiver, and the at least one temperature sensor. The processor is configured to control the optical transmitter to transmit the outgoing optical signal configured to detect an object, receive an object optical signal, reflected by the object, through the optical receiver, identify a temperature of the lidar device through the temperature sensor in response to the identifying of intensity of the object optical signal being less than reference intensity, and adjust a bandpass of an optical filter of the optical receiver based on the temperature of the lidar device.
