Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a static projection surface is used for texture projection, then the system structure is simple, but the displayed objects are highly distorted and form disruptive artifacts
Solution Approach 1:
The patent transforms the static projection surface into a dynamic adaptive projection surface that adjusts its geometry based on detected object characteristics. The projection surface is continuously adapted to match the real environment geometry, eliminating distortion artifacts while maintaining system simplicity through algorithmic control.
Solution Approach 2:
The patent changes the geometric parameters of the projection surface dynamically based on sensor data and object detection results. By adjusting projection parameters according to the actual environment, the system achieves high display accuracy without requiring complex hardware modifications.
2Ease of operation
If a static projection surface is used, then the system is easy to operate, but obstacles are displayed with distortion and unclear representation
Solution Approach 1:
The patent implements a feedback mechanism where sensor data and object detection results are continuously used to adjust the projection surface parameters. This closed-loop control automatically optimizes the display accuracy for obstacle representation without requiring manual intervention, maintaining ease of operation while achieving high precision.
3Power
If texture projection is performed on a static surface, then the processing is computationally simple, but the displayed image contains disruptive artifacts
Solution Approach 1:
The patent applies dynamic adaptation of the projection surface to eliminate artifacts while maintaining computational efficiency. By adjusting the projection geometry to match the actual environment, the system preserves image quality without requiring excessive processing power for complex rendering operations.
Data Source
AI summary
The invention relates to a camera surround view system for a vehicle, comprising at least one vehicle camera which supplies camera images that are processed by a data processing unit in order to generate an image of the surroundings, said image of the surroundings being displayed on a display unit. The data processing unit re-projects textures, which are detected by the vehicle camera, on an adaptive re-projection surface, which is similar to the area surrounding the vehicle, said re-projection surface being calculated on the basis of sensor data provided by vehicle sensors. The data processing unit adapts the re-projection surface depending on a position and an orientation of a virtual camera.
