Assignee: BEIJING BAIDU NETCOM SCIENCE TECHNOLOGY CO., LTD.
Field: Measurement (Instruments)
Classification: CPC B  G | IPC B  G

Claim 3:
4. An apparatus for processing map data applied to an autonomous driving system comprising at least one processor, at least one sensor communicatively connected with the at least one processor, a memory communicatively connected with the at least one processor;
the memory stores instructions executable by the at least one processor;
wherein the at least one processor, when running the instructions stored in the memory, is enabled to:
control an input interface to input initial positioning data collected by the at least one sensor to obtain fused positioning data, wherein the initial positioning data is data collected by multiple sensors in a data collecting unit without offset processing, and the initial positioning data and the fused positioning data are data in a first coordinate system;
perform the offset processing on the fused positioning data to obtain offset positioning data, wherein the offset processing comprising encrypting data in the first coordinate system to data in a second coordinate system by means of a one-way mapping;
acquire image data and radar data collected by the at least one sensor;
acquire a map in the second coordinate system;
control the input interface to input the image data, the radar data, the map in the second coordinate system, and the offset positioning data to the at least one processor to obtain the relative positioning data, wherein the at least one processor is configured for map matching processing;
correct the offset positioning data according to the relative positioning data to obtain target positioning data, wherein the target positioning data is data in the second coordinate system; and
determine a position of a vehicle corresponding to the autonomous driving system according to the target positioning data.
