摘要： This application provides a lane line tracking method and apparatus. The method includes: obtaining a first prediction value, where the first prediction value is used to indicate a lane line model in a vehicle coordinate system, and is obtained through prediction by using motion information of an autonomous driving vehicle at a prior moment; obtaining first detection information, where the first detection information includes a pixel of a lane line in an image coordinate system at a current moment; determining a first mapping relationship based on the first prediction value and the first detection information, where the first mapping relationship is used to indicate a real-time mapping relationship between the image coordinate system and the vehicle coordinate system; and determining a second prediction value based on the first mapping relationship, where the second prediction value is used to indicate a correction value of the first prediction value. A real-time mapping relationship between two coordinate systems is obtained by using a prediction value and detection information, so that impact of road surface changes and the like can be eliminated, to improve accuracy of lane line tracking. In addition, the method does not need to be based on a plane assumption and a lane line parallel assumption, so that the method is more universal.

摘要： This application provides an apparatus and a method for implementing data synchronization during neural network inference, relates to an artificial intelligence (Artificial Intelligence, AI) field, and specifically relates to neural network inference technologies. The apparatus includes: a memory, configured to store a first feature map; and a neural-network processing unit NPU, configured to: obtain the first feature map from the memory, where the first feature map includes M blocks, and M is a positive integer; separately perform, in an asynchronous manner, inference computation at at least two layers of a neural network model on the M blocks to obtain M inference results, where the asynchronous manner means that data synchronization is not performed on an intermediate result obtained after inference computation at one layer of the neural network model is performed on each block, and inference computation at a next layer continues to be performed on the intermediate result; and perform data synchronization on the M inference results to obtain synchronized data. Because the NPU performs data synchronization only after completing inference computation at the at least two layers of the neural network model, a quantity of data synchronization times in a neural network inference process is relatively small, and less data migration overheads are generated.

摘要： This application discloses a method and an apparatus for passing through a barrier gate crossbar by a vehicle, and relates to the field of autonomous driving, to resolve a problem of how a vehicle passes through a barrier gate crossbar in an autonomous driving mode. The method includes: A vehicle collects data of a plurality of to-be-detected barrier gate crossbars around the vehicle by using a sensor mounted on the vehicle, and transmits the data of the plurality of to-be-detected barrier gate crossbars to a processor; the processor determines data of a target barrier gate crossbar from the data of the plurality of to-be-detected barrier gate crossbars based on a pose of the target barrier gate crossbar, where the target barrier gate crossbar is a barrier gate crossbar of a lane on which the vehicle is located; and the processor determines a status of the target barrier gate crossbar based on the data of the target barrier gate crossbar, and controls, based on the status of the target barrier gate crossbar, the autonomous driving vehicle to pass through the target barrier gate crossbar.

摘要： This application discloses a positioning method, a related apparatus, and a related device, which may be applied to vehicle self-driving in the artificial intelligence field, and specifically relates to a vehicle positioning method. The method includes: A positioning device corrects a low-precision first pose by using N first geometric features extracted from first point cloud data collected by a point cloud collection apparatus, to obtain a high-precision second pose. Compared with point cloud data in the prior art, in embodiments of this application, a geometric feature with a small data volume is used for positioning, to greatly reduce a data operation amount, so that time consumption of vehicle positioning is less, and real-time performance of positioning is good.

摘要： The invention relates to a data processing system and a date processing method. The data processing system is configured to perform a hardware transactional memory (HTM) transaction. The data processing system comprises a byte-addressable nonvolatile memory for persistently storing data and a processor being configured to execute an atomic HTM write operation in connection with committing the HTM transaction by writing an indicator to the nonvolatile memory indicating the successful commit of the HTM transaction.
