Vehicle Surroundings Display Integrating Map and LiDAR Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle surroundings information displaying systems only provide a limited range of surroundings information, primarily focusing on short-distance overhead images, which does not offer a comprehensive view of the vehicle's environment.
Innovation Solution
A system that combines a map image, a vehicle mark, an overhead image, and surroundings information to generate a display image on a panel, using sensors like LiDAR to gather point group data for distance information, allowing for a broader range of surroundings to be displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If only overhead images are displayed based on camera images, then the display system is simple, but the range of surroundings information is limited to short distances
Solution Approach 1:
The patent combines multiple information sources (map image, overhead image, and surroundings information image) into a single integrated display. The map image provides the base layer showing the vehicle and its location, the overhead image is superimposed to show the immediate surrounding area, and the surroundings information image is overlaid to display distance information from the vehicle. This merging of multiple data sources expands the effective display range without requiring separate display systems.
Solution Approach 2:
The patent adds a new dimension to the display by incorporating distance information from the vehicle into the visual representation. By using point group data that indicates distances from the vehicle and creating a surroundings information image, the system transforms 2D overhead view into a multi-layered display that encodes 3D spatial information, effectively expanding the perceivable range.
2Loss of information
If multiple data sources are combined to expand display range, then the range of surroundings information is improved, but the device complexity increases
Solution Approach 1:
The patent divides the information display into distinct segments or layers: the map image showing vehicle location, the overhead image showing immediate surroundings, and the surroundings information image showing distance data. Each segment processes and displays specific types of information independently, then they are composited together. This segmentation allows comprehensive information display while managing complexity through modular processing.
