Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle safety cameras face limitations in distance measurement accuracy, control reliability, and recognition rate, particularly in providing convenience for drivers unfamiliar with driving, leading to potential traffic accidents due to degraded object recognition during running.
Innovation Solution
A vehicle safety control apparatus using two cameras, one with a narrow angle lens for vertical component recognition and another with a wide angle lens for horizontal component recognition, along with an image processing unit, recognition unit, and storage unit to enhance image recognition and storage of relevant data for improved safety control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single camera is used for vehicle safety control, then cost and size are reduced, but distance measurement accuracy and control reliability are degraded
Solution Approach 1:
The patent combines a narrow-angle camera and a wide-angle camera into a unified vehicle safety control system. The narrow-angle camera captures distant objects with higher precision, while the wide-angle camera captures broader scenes including closer objects. The image processing unit fuses data from both cameras, achieving accurate distance measurement across all ranges without requiring complex stereo vision algorithms.
Solution Approach 2:
The dual-camera system serves multiple functions simultaneously: the narrow-angle camera provides precise distance measurement for far objects, the wide-angle camera provides broad scene coverage and detects close objects, and together they enable comprehensive object detection, distance measurement, and collision warning across the entire field of view.
2Measurement precision
If a stereo camera is used to improve control performance and reduce vertical distance measurement error, then measurement accuracy is improved, but field of view is narrowed
Solution Approach 1:
The patent merges the advantages of narrow-angle and wide-angle cameras by using both simultaneously. The narrow-angle camera provides precise vertical distance measurement similar to stereo cameras, while the wide-angle camera compensates for the limited field of view by capturing broader scenes. The image processing unit integrates data from both cameras to achieve both precision and wide coverage.
3Device complexity
If a single camera is used for all safety control functions, then device complexity is reduced, but recognition rate for current objects during running is degraded
Solution Approach 1:
The patent combines narrow-angle and wide-angle cameras to achieve high recognition rates for moving objects. The narrow-angle camera provides stable, high-resolution images of distant objects, while the wide-angle camera captures objects entering the field of view and provides context. The image processing unit fuses these inputs to maintain high recognition accuracy during vehicle motion.
4Device complexity
If one camera is used for control without redundancy, then device complexity is reduced, but control reliability is degraded
Solution Approach 1:
The patent combines narrow-angle and wide-angle cameras to provide functional redundancy. If one camera fails or provides insufficient data, the other can compensate to maintain basic safety functions. The image processing unit is configured to handle data from both cameras and can operate with reduced performance if one camera is unavailable, ensuring continued control reliability.

AI summary
A vehicle safety control apparatus using cameras includes a first camera configured to photograph a current object at at least one of a narrow angle and a straight angle during running, a second camera configured to photograph the current object at a wide angle during the running, an image processing unit configured to perform image processing on first current object image data captured by the first camera and second current object image data captured by the second camera, a recognition unit configured to recognize the first and second current object image data on which the image processing unit has performed the image processing, a storage unit configured to cause the recognized data to match preset reference object-specific data and separately store the data matching the preset reference object-specific data; and a control unit configured to receive the recognized data and deliver a storage command to the storage unit.
