Engineering Contradiction Analysis
1Measurement precision
If square colored surfaces are used as synthetic elements in current camera systems, then the display can be generated quickly, but the elements are not aligned with the actual environment making it difficult for drivers to assess distances
Solution Approach 1:
The patent creates a virtual copy of the real environment by mapping three-dimensional sensor data (from LiDAR, cameras, or ultrasonic sensors) into a virtual space that replicates the actual surroundings. This virtual copy includes virtual objects corresponding to real objects, allowing the intersection line to accurately represent distance and spatial relationships, thereby solving the distance assessment problem while maintaining environmental fidelity.
Solution Approach 2:
The patent transitions from two-dimensional synthetic elements (square colored surfaces) to three-dimensional virtual objects in a virtual space. By creating a three-dimensional landscape with virtual objects that have spatial dimensions and positions matching the real environment, the system enables accurate distance assessment through the intersection line's position and orientation in 3D space, rather than relying on flat 2D representations.
2Reliability
If a three-dimensional virtual landscape with movable virtual surfaces is created, then a realistic and intuitive representation is achieved, but the computational complexity and processing requirements increase
Solution Approach 1:
The patent employs a multi-functional computing unit that performs sensor data processing, three-dimensional virtual landscape generation, virtual element creation and animation, intersection line calculation, and video sequence generation within a single integrated system. This universal approach consolidates multiple functions into one device, managing computational complexity through integration while achieving reliable and accurate environment representation.
Solution Approach 2:
The patent pre-establishes a virtual space framework and virtual objects before generating the final display. By creating the three-dimensional virtual landscape structure in advance and pre-defining virtual elements that will move along predetermined paths, the system prepares computational templates that reduce real-time processing requirements, thereby managing complexity while maintaining representation accuracy.
3Ease of operation
If synthetic elements are superimposed on video images, then drivers can estimate remaining distance, but the elements are not aligned with the actual environment reducing intuitiveness
Solution Approach 1:
The patent creates accurate virtual copies of real environmental objects in a virtual space, where each virtual object corresponds to a real object detected by sensors. The intersection line is generated based on the relationship between virtual elements and virtual objects, preserving the spatial and contextual information of the real environment. This copying approach maintains environmental context accuracy while providing intuitive distance estimation for drivers.
Solution Approach 2:
The patent transitions from two-dimensional synthetic elements superimposed on video images to three-dimensional virtual elements in a virtual space that accurately represent real-world objects. This dimensional enhancement allows the intersection line to convey spatial relationships and distance information that are geometrically accurate and intuitively understandable, preserving environmental context while improving driver interface intuitiveness.
