Adaptive Projection Surface for Vehicle Surround View Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surround view systems for vehicles suffer from distortions in the projection of environmental data when the perspective changes, particularly when virtual camera positions differ from actual camera perspectives.
Innovation Solution
The solution involves adding the 3D form of recognized objects to the projection surface of the surround view system, allowing for a more accurate and distortion-free representation of the vehicle environment by adapting the projection surface to include detailed, perspective-corrected environmental data.

Engineering Contradiction Analysis
1Manufacturing precision
If environmental data is projected onto a fixed projection surface, then the system structure is simple, but distortions occur when perspective changes
Solution Approach 1:
The projection surface is transformed from a fixed static structure to a dynamic adaptive surface that automatically adjusts its shape based on detected objects. The system calculates a new projection surface shape for each detected object and applies it accordingly, allowing the surface to adapt to different environmental conditions and perspective requirements without manual intervention.
Solution Approach 2:
The system changes the geometric parameters of the projection surface dynamically. When an object is detected, the evaluation unit calculates new parameters (shape, orientation, position) for the projection surface and transforms the environmental data accordingly. This parameter adaptation allows accurate projection without requiring a complex fixed structure.
2Manufacturing precision
If the projection surface is adapted to include 3D object shapes, then projection quality improves, but processing complexity increases
Solution Approach 1:
The system performs self-adjustment by automatically detecting objects and independently calculating the appropriate projection surface parameters. The evaluation unit processes the environmental data, identifies objects, determines their 3D shapes, and automatically adapts the projection surface without external control. This autonomous operation reduces the need for complex external processing systems.
Solution Approach 2:
The system performs preliminary detection and characterization of objects before projection. By pre-identifying objects and calculating their 3D shapes in advance, the system prepares the projection surface parameters ahead of time, allowing for efficient and accurate projection without requiring complex real-time processing during the actual projection operation.
