Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular safety systems require multiple dedicated lenses to detect lane departure and obstacles, increasing fabrication costs and limiting the ability to simultaneously detect panoramic images and barriers, as no wide-angle lens can effectively support all four technical characteristics.
Innovation Solution
A dynamic lane line detection system using a vehicular image integration unit with four wide-angle lenses and a signal receiving device to transform distorted images into planar images, automatically switching safety devices based on vehicular signals for effective lane departure warning and obstacle detection without dedicated lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple dedicated lenses are used for lane detection and obstacle detection, then detection accuracy is improved, but device complexity and fabrication cost increase
Solution Approach 1:
The patent applies universality by enabling wide-angle lenses to perform multiple functions: capturing panoramic images, detecting lane lines, and identifying obstacles. The image processing system analyzes single images or image sequences from these wide-angle lenses to detect various features, eliminating the need for separate dedicated lenses for each function.
Solution Approach 2:
The patent merges multiple detection functions (panoramic imaging, lane detection, obstacle detection) into a single integrated system using wide-angle lenses. The image processing unit combines image data from the same lens for different detection purposes, reducing the total number of lenses required while maintaining detection capabilities.
2Reliability
If multiple dedicated lenses are used for different safety devices, then detection capability is improved, but fabrication cost increases
Solution Approach 1:
The wide-angle lenses are designed to serve multiple safety detection functions simultaneously. The same lens captures images used for panoramic views, lane line detection, and obstacle identification, reducing the total lens count and associated fabrication costs while maintaining comprehensive detection capability.
3Adaptability or versatility
If four wide-angle lenses are integrated into a single system, then detection versatility is improved, but image processing complexity increases
Solution Approach 1:
The image processing is segmented into distinct functional modules: panoramic image generation, lane line detection, and obstacle detection. Each module processes specific features from the wide-angle lens images independently, managing complexity through functional decomposition while maintaining versatile detection capabilities.
4Area of stationary object
If wide-angle lenses are used for panoramic detection, then detection coverage is improved, but lane line detection accuracy deteriorates due to image distortion
Solution Approach 1:
The system changes processing parameters by analyzing image sequences rather than single static images. It detects lane lines by tracking their movement and positional changes across multiple frames, compensating for wide-angle distortion through temporal analysis and motion-based recognition rather than relying solely on geometric precision in single distorted images.

AI summary
A dynamic lane line detection system and method is disclosed herein. Four wide-angle lenses are respectively arranged at four sides of a vehicle and capture distorted images. A vehicular image integration unit transforms the distorted images into an ordinary planar image and presents the planar image on an image display device together with an image of lane lines as information of lane departure warning for the driver. The system undertakes moving obstacle detection, around view monitor, or parking assistant according to images captured by four wide-angle lenses and the gearshift signal, speed signal, turning angle signal received by a vehicular signal receiving device. The present invention uses the wide-angle lenses and the vehicular image integration unit to effectively integrate lane departure information with a panoramic image, whereby to decrease the economical burden of the vehicle buyer and reduce the volume of hardware.
