Abstract: Provided are a high-precision map data collection method and apparatus, an electronic device, and a storage medium, relating to the field of data processing technology and, in particular, to the field of self-driving technology. The solution includes acquiring high-precision map data collected by a data collection device at a target time; and determining the satellite navigation system time corresponding to the target time and establishing an association between the high-precision map data and the satellite navigation system time.

Abstract: A method of processing map data, an electronic device, and a storage medium, which relate to a field of a computer technology, in particular to fields of intelligent transportation technology, image processing technology, etc. The method of processing the map data includes: processing sensor data for a traffic object to obtain point cloud data for the traffic object, where the sensor data includes image data; obtaining mesh data based on the point cloud data; processing the image data based on an association between the mesh data and the image data, so as to obtain processed image data; and obtaining the map data for the traffic object based on the processed image data.
