Abstract: This application provides a parameter calibration method and apparatus, which may be applied to calibration of an intrinsic parameter and an extrinsic parameter of an image shooting device. According to the method and apparatus, with a position of a calibration pattern fixed, a position and an angle of the image shooting device relative to the calibration pattern are accurately adjusted by changing a pose parameter of the image shooting device, so that the image shooting device photographs the calibration pattern at each given position and angle relative to the calibration pattern, to obtain at least one shooting result. The shooting result can correspond to coordinate in a pixel coordinate system and a world coordinate system, so that accuracy of an intrinsic parameter and an extrinsic parameter is correspondingly calculated.

Abstract: A sensor detection method, a sensor detection apparatus, and a vehicle are provided. The method may be applied to the sensor detection apparatus. The method includes: a sensor detection apparatus obtains data collected by a plurality of sensors; the sensor detection apparatus extracts a feature from data collected by each of the plurality of sensors, to obtain a plurality of pieces of feature data; the sensor detection apparatus fuses the plurality of pieces of feature data to obtain fused data; and the sensor detection apparatus performs inference on the fused data to obtain clean status information of each of the plurality of sensors. According to embodiments of this application, accuracy of detecting a clean status of a sensor can be improved.

Abstract: The present disclosure relates to a device for verifying estimated depth information. The device obtains an image of a scene, wherein the image comprises at least one object of interest having a set of points, obtains a height information for at least one point from the set of points of the object of interest, and estimates a first depth information for the at least one point, based on the obtained height information and detects a corresponding position of the at least one point in the obtained image. The device further receives, from another device, a second depth information for the at least one point, and determines a validity of the estimated second depth information, based on determining a measure of dissimilarity between the first depth information and the second depth information for the at least one point.
