Vehicle Camera Alignment Correction Using Ground Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles manufactured without camera correction lead to mismatch issues between adjacent images in the around view system, requiring separate correction operations that can be inconvenient and prone to errors.
Innovation Solution
A method and device that utilize a processor and cameras to receive pattern information, calculate parameters based on vehicle trajectory, and correct camera alignment using pattern members disposed on the ground, allowing for in-manufacture and on-the-go camera correction without additional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If camera correction is not performed during vehicle manufacturing, then the vehicle can be shipped quickly without additional correction steps, but the adjacent images in the around view system will be mismatched causing customer complaints
Solution Approach 1:
The patent performs camera correction as a preliminary action during the vehicle manufacturing process before the vehicle is shipped to the customer. The correction is integrated into the manufacturing workflow, using pattern members placed on the ground and captured by cameras to calculate and adjust camera parameters, ensuring accurate image alignment is established before delivery.
Solution Approach 2:
The system uses the vehicle's own cameras to capture pattern information and perform self-correction during manufacturing. The cameras mounted on the vehicle circumference capture images of pattern members, and the processor automatically calculates correction parameters and adjusts camera alignment without requiring external correction equipment or manual intervention.
2Ease of operation
If separate camera correction operations are required after vehicle shipment, then customers can receive vehicles immediately, but additional correction steps increase customer inconvenience and potential for error
Solution Approach 1:
The patent performs camera correction as a preliminary action during the vehicle manufacturing process before the vehicle is shipped to the customer. The correction is integrated into the manufacturing workflow, using pattern members placed on the ground and captured by cameras to calculate and adjust camera parameters, ensuring accurate image alignment is established before delivery.
3Measurement precision
If additional correction devices are used for camera alignment, then correction accuracy can be improved, but the device complexity and cost increase
Solution Approach 1:
The system uses the vehicle's own cameras to capture pattern information and perform self-correction during manufacturing. The cameras mounted on the vehicle circumference capture images of pattern members, and the processor automatically calculates correction parameters and adjusts camera alignment without requiring external correction equipment or manual intervention.
Solution Approach 2:
The patent makes the vehicle's existing cameras serve a dual function: their primary function for normal operation and an additional function for self-correction by capturing pattern member images. This eliminates the need for separate correction devices, as the same cameras perform both operational and calibration tasks.

AI summary
A method for correcting a camera by using a plurality of pattern members placed on the ground of a vehicle enables receiving pattern information of a plurality of pattern members by using a plurality of cameras disposed on the circumference of a vehicle being driven, calculating a first parameter on the basis of the pattern information, calculating trajectory information of the vehicle by using the pattern information, and calculating a second parameter by correcting the first parameter on the basis of the trajectory information of the vehicle.
