Solution Overview
Problem
Panoramic surrounding view systems in vehicles suffer from distortion issues in constructed three-dimensional models, making it difficult for users to accurately identify surrounding objects and judge distances, thereby increasing driving risks.
Innovation Solution
A method for constructing a 3D panoramic view model involves identifying target objects in environment images, determining coordinates in multiple coordinate systems, and applying correction parameters to eliminate distortion, resulting in a more accurate representation of the vehicle's surroundings.

Engineering Contradiction Analysis
1Reliability
If a three-dimensional model is constructed from camera images to simulate the environment around the vehicle, then users can better understand the surrounding environment, but the constructed objects in the model are prone to distortion making it difficult to accurately identify objects and judge distances
Solution Approach 1:
The patent replaces traditional geometric construction methods with a physics-based approach using bird's-eye view images as reference. Instead of relying solely on mathematical coordinate transformations that cause distortion, the system uses actual captured images from above to guide the construction of three-dimensional models, substituting mechanical geometry with optical reference data.
Solution Approach 2:
The patent introduces bird's-eye view images as an intermediary reference between the camera images and the three-dimensional model construction. These intermediate images serve as a bridge that provides accurate spatial relationships and object positions, mediating the transformation from raw camera data to the final three-dimensional representation without direct geometric distortion.
2Manufacturing precision
If multiple coordinate systems are used to represent the same spatial information, then the representation becomes more complex, but this enables more accurate coordinate transformation and distortion correction
Solution Approach 1:
The patent segments the coordinate representation into multiple distinct coordinate systems, each optimized for specific purposes. Instead of using a single complex coordinate system, the method divides the spatial representation into camera coordinate system, bird's-eye view coordinate system, and world coordinate system, allowing each to handle specific transformation tasks independently and more accurately.

AI summary
A method for constructing a 3D panoramic view model is provided using a vehicle-mounted device. The method includes identifying a target object in an environment image, and determines first coordinates of the target object in a first coordinate system corresponding to the environment image. The environment image is converted to an aerial view, and second coordinates of the target object are determined in a second coordinate system corresponding to the aerial view. A third coordinate of the target object is determined in a third coordinate system. A fourth coordinate of the target object is determined in a fourth coordinate system, and an initial distance is determined between the target object and a vehicle. A target distance is determined and a target 3D panoramic view model of the vehicle is constructed according to the target distance and the environment image. The method improves the safety of users driving.
