Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display technologies fail to accurately represent the locations and shapes of objects near the vehicle due to distortion in three-dimensional images, making it difficult for drivers and passengers to identify nearby pedestrians, buildings, or other vehicles.
Innovation Solution
A processor modifies a three-dimensional mesh based on the actual locations of detected objects using sensors like cameras, radar, or lidar modules to generate an accurate 3D image by calculating distances and azimuths, selecting or generating meshes that correctly represent the objects relative to the vehicle.

Engineering Contradiction Analysis
1Area of stationary object
If a three-dimensional image is generated using conventional projection methods, then the viewing angle is expanded, but the accuracy of object location and shape representation deteriorates due to distortion
Solution Approach 1:
The patent applies dynamics by making the projection surface deformable rather than fixed. The projection surface dynamically adjusts its shape based on detected object positions, allowing it to accommodate objects at various distances and angles. This dynamic adaptation resolves the contradiction by enabling both expanded viewing coverage and accurate object representation simultaneously - the surface expands to cover more area while maintaining proper geometric relationships for precision.
Solution Approach 2:
The patent changes the geometric parameters of the projection surface based on object detection data. By modifying the surface configuration according to object positions, distances, and angles, the system optimizes the projection for each specific scenario. This parameter adjustment allows the system to maintain measurement precision across different viewing conditions while expanding the effective viewing angle through adaptive surface deformation.
2Device complexity
If the projection surface is fixed, then the device complexity is reduced, but the adaptability to different object positions and distances deteriorates
Solution Approach 1:
The projection surface transitions from a static structure to a dynamic one that can be deformed based on object positions. This dynamic capability enables the surface to adapt to various object configurations without requiring multiple fixed surfaces or complex mechanical adjustment mechanisms. The deformation is controlled through computational methods, maintaining relatively simple device structure while achieving high adaptability.
Solution Approach 2:
The patent introduces an additional degree of freedom by allowing the projection surface to deform in three-dimensional space. This dimensional flexibility enables the surface to conform to objects at different distances and angles without requiring complex mechanical structures. The surface can be imagined as a flexible membrane that adapts its shape, providing versatile object coverage while keeping the overall device architecture relatively simple.

AI summary
Provided is an apparatus for generating an image, the apparatus including a processor configured to detect at least one object near a vehicle by using a result of sensing a surrounding area of the vehicle, determine a direction and a distance from the vehicle to the detected at least one object, and generate an image of the surrounding area of the vehicle based on the determined direction and distance. Therefore, the apparatus may accurately express a shape of the object and a relative location between the vehicle and the object on a three-dimensional (3D) image of the surrounding area of a vehicle.
