Abstract: Provided are an on-board data processing method, an electronic device and a storage medium, which relates to a field of artificial intelligence technology, and in particular, to fields of Internet of Things, autonomous parking, automatic driving and the like. The on-board data processing method includes: comparing collected user behavior data with on-board data, to obtain difference data used to characterize scene data that is related to user behavior and not included in the on-board data; reporting the difference data; and updating the on-board data by using a downloaded data package obtained through the difference data, in response to a data update operation. By adopting the method, the accuracy of driving in the automatic driving scene may be improved.

Abstract: The present disclosure provides a method and apparatus for processing three dimensional graphic data, a device, a storage medium and a product, relating to a field of artificial intelligence, in particular to a field of autonomous driving. The specific implementation is: receiving a data compression request for a target graphic element in a three dimensional electronic map, and obtaining at least one vertex data corresponding to the target graphic element; extracting a global coordinate matrix with a shared attribute in the at least one vertex data; extracting local coordinate data with a private attribute respectively corresponding to the at least one vertex data; and sending, in response to a graphic drawing request for the target graphic element, the global coordinate matrix and the local coordinate data respectively corresponding to the at least one vertex data to a graphic display device.
