Abstract: A method of correcting distance distortion to improve detection accuracy of a Light Detection and Ranging (LiDAR) according to one embodiment of the present disclosure includes acquiring measurement data for detecting a target by the LiDAR, estimating a range of a distance offset through comparison between the measurement data and reference data, estimating the distance offset based on a correlation coefficient between the measurement data and the reference data in the range of the distance offset, and correcting the measurement data using the estimated distance offset.

Abstract: Provided are a light wave detection and ranging (LiDAR) sensor, an operating method thereof, and a vehicle including the LiDAR sensor. The LiDAR sensor is configured to detect surroundings of a vehicle, and includes a transmitter configured to generate light and transmit the light to an object, a receiver configured to receive light reflected from the object, and a signal processor configured to detect the object by processing a signal of the light received by the receiver, wherein the object is detectable both at a long distance and a short distance, and when the object is detected at the short distance, the transmitter outputs light while gradually reducing an intensity of the light, compared to when the object is detected at the long distance, and the signal processor determines reflectivity for a cell included in a sensor on the basis of an activation maintenance time or an activation frequency in the cell according to the signal while the intensity of the received signal of the light is reduced gradually.

Abstract: Disclosed herein is a driving assistance apparatus including a memory storing a program for determining a state of a LIDAR and a processor configured to execute the stored program, wherein the processor is further configured to compare data about a first reception signal received firstly after light is output from the LiDAR with reference data, and determine that the LiDAR is contaminated when an error between the data about the first reception signal and the reference data is greater than a threshold.
