摘要： A method for calibrating image distortion, apparatus, electronic device, and computer readable storage medium are disclosed. The method for calibrating image distortion includes: obtaining an original image captured by a camera; calculating a deformation degree of foreground objects when the original image includes the foreground objects; and performing a distortion calibration and a spherical projection on the original image to obtain a target image when the deformation degree of the foreground objects is greater than a predetermined threshold. The method for calibrating image distortion provided by the disclosure can realize fast distortion calibration of ultra-wide-angle image with low computational complexity and obtain better calibration effect.

摘要： An external parameter calibration method for an image acquisition apparatus is disclosed. The method includes acquiring images from images acquired by the image acquisition apparatus. The images contain reference objects acquired by the image acquisition apparatus during the driving of the vehicle. The reference objects in the images are divided into a number of sections along a road direction in which the vehicle is located, and reference objects in each of the sections are fitted into straight lines. Pitch angles and yaw angles of the image acquisition apparatus are determined based on vanishing points of a straight line in each of the sections. The sequences of the determined pitch and yaw angles are filtered. Straight portions in the road from the filtered sequences of pitch and yaw angles are obtained. Data of the pitch angles and yaw angles corresponding to the straight portions are stored to a data stack.

摘要： The present disclosure relates to a method for inter-core communication of a multi-core processor, a processor, an inter-core communication system and a computer readable storage medium. The method for inter-core communication comprises: receiving a communication request sent by an initiating core for communication with receiving cores; and instructing, on the basis of the communication request, the initiating core to communicate with the receiving cores by using a delivery message to invoke interfaces of services in the receiving cores; wherein the delivery message is service-oriented and corresponds to the interfaces of the services in the receiving cores. According to the method for inter-core communication of the present disclosure, services built in various systems can interact in a uniform and universal manner by means of the service-oriented delivery message. Therefore, the portability of application programs located on different cores can be improved, and the development difficulty is reduced.
