Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive equipment and manual data editing are used for high-precision map production, then map production accuracy is improved, but production cost increases and efficiency decreases
Solution Approach 1:
The patent uses sensor data from vehicle-mounted devices to create reference maps that copy real-world environmental information. These reference maps serve as templates for generating final high-precision maps, eliminating the need for expensive manual surveying equipment while maintaining accuracy through automated data collection and processing
Solution Approach 2:
The patent replaces manual mechanical surveying and data editing processes with automated sensor-based systems. Vehicle-mounted sensors automatically collect environmental data, and servers automatically process and fuse this data to generate maps, substituting manual labor with automated electronic systems that are both cheaper and more efficient
2Measurement precision
If manual data editing is used for map production, then map production accuracy is improved, but production cost increases
Solution Approach 1:
The system enables self-service map production where vehicle-mounted devices automatically collect sensor data and servers automatically process this data to generate reference maps. This eliminates the need for expensive manual data editing while maintaining accuracy, as the automated system performs quality control and map generation without human intervention
Solution Approach 2:
The patent creates reference maps by copying environmental information from sensor data collected by vehicle-mounted devices. These reference maps serve as accurate templates that can be used to generate final high-precision maps without requiring expensive manual surveying or editing operations
3Measurement precision
If traditional map collection methods are used, then map production accuracy is maintained, but data collection cost increases and update frequency decreases
Solution Approach 1:
The patent enables continuous map updates by having vehicle-mounted devices continuously collect sensor data during normal vehicle operation. This continuous data collection allows the system to maintain and update maps in real-time as vehicles traverse different areas, ensuring high accuracy while enabling frequent updates without stopping vehicle operations
Solution Approach 2:
The system creates updated reference maps by copying current environmental information from continuously collected sensor data. This allows maps to be updated frequently to reflect current conditions while maintaining position accuracy, as the automated copying process can operate continuously without disrupting vehicle operations

AI summary
The invention proposes a method and an apparatus for processing a map, an electronic device, a medium and a vehicle. The method includes: obtaining a plurality of reference maps from vehicle-mounted devices; determining map elements included in the plurality of reference maps and a first element position where each map element is located; and obtaining a target map by fusing the map elements in the plurality of reference maps based on the first element position where each map element is located. The accuracy of the map element position is improved and the consistency between the target map and the real world is then ensured. The cost of data collection and making a map is reduced, the efficiency of making a map and update frequency may be effectively improved, enhancing the timeliness of the map.
