  • Patent number: 12183040
    Abstract: The panoramic surround view system in the vehicle can control the projection device of the vehicle to project the preset pattern on the ground around the vehicle, acquire the plurality of target photographs including the preset pattern, and generate the target calibrating data of the surround view cameras according to the plurality of target photographs, so that the surround view cameras of the panoramic surround view system can be calibrated by using the target calibrating data to obtain the panoramic surround view image. Therefore, when the user needs to re-calibrate the calibrating data of the image splicing of the panoramic surround view system of the vehicle, the calibrating process can be completed by only by using the projection device of the vehicle, without using a special calibrating site and equipment, thus simplifying the calibrating operation steps and saving time.

  • Publication number: 20230192086
    Abstract: A reversing control method and system and a vehicle, which relate to the technical field of vehicles. In the method, after receiving a reversing instruction for a vehicle, a first reversing trajectory of the vehicle can be acquired; the vehicle can be controlled to reverse according to the first reversing trajectory, such that a driver does not need to control the vehicle, thus avoiding tedious operation by the driver; during a reversing process the first reversing trajectory can be adjusted according to first environmental obstacle information of the vehicle, to acquire a second reversing trajectory; and the vehicle is then controlled to reverse according to the second reversing trajectory. Thus, the danger caused by environmental obstacles during a reversing process may be avoided, and potential safety hazards in process of reversing a vehicle are eliminated.
