Abstract: The present disclosure provides a method for measuring a sensing range of a vehicle, a device and a medium, and relates to a technical field of automatic driving. The method includes: determining a target road side unit to be measured according to a road side unit identifier; when it is detected that the vehicle receives a road-side message from the target road side unit, determining vehicle positioning information of the vehicle when the road-side message is received; and determining a sensing range of the vehicle to the target road side unit in a target lane in which the vehicle travels according to the vehicle positioning information.

Abstract: A method, an apparatus, a computer device and a storage medium for autonomous driving determination are proposed. The method includes: obtaining information about a driving scenario of an autonomous vehicle when a preset trigger condition is met; comparing the information about the driving scenario with an autonomous driving capability of the autonomous vehicle; determining, according to a comparison result, whether the autonomous vehicle is adapted to employ an autonomous driving mode in the driving scenario. The technical solution of the present disclosure may be applied to improve the safety of the vehicle and the user.

Abstract: A method and apparatus for calibrating a camera are provided. A specific embodiment of the method includes: acquiring an image-point cloud sequence, the image-point cloud sequence including at least one group of an initial image and point cloud data collected at a same time, the initial image being collected by a camera provided on an autonomous vehicle and the point cloud data being collected by a radar provided on the autonomous vehicle; determining target point cloud data of initial images corresponding to groups of image-point cloud in the image-point cloud sequence; and matching the target point cloud data with the corresponding initial images in the image-point cloud sequence to determine a correction parameter of the camera.
