Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blind spot detection devices on vehicles cannot detect moving objects in front of the side view mirrors, leading to driving risks due to unknown blind spots.
Innovation Solution
An electronic side view mirror warning system with cameras mounted on the front of the vehicle to capture side images of the front wheels, a processor for image recognition, and a display device to issue warnings based on driving road conditions and obstacles, enhancing safety by actively detecting and alerting the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If blind spot detection devices are mounted on side view mirrors to detect objects at the rear, then the driver can obtain information on whether there are objects on the sides of the vehicle, but the system cannot detect moving objects in front of the side view mirror
Solution Approach 1:
The patent transitions from rearward-facing detection to forward-facing detection by changing the spatial orientation of the camera. The camera is mounted on the front of the vehicle to capture images of the front wheel area, enabling detection in a previously uncovered forward blind spot zone.
Solution Approach 2:
The system uses a multi-functional integrated approach combining camera capture, processor-based image recognition, and driver warning capabilities. The same system architecture can detect both road conditions and obstacles, providing universal monitoring functionality.
2Reliability
If cameras are mounted on the front of the vehicle to capture side images of front wheels, then the system can detect moving objects in front of the side view mirror, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical blind spot monitoring systems with an optical-based camera and electronic image processing system. The processor analyzes captured images to detect obstacles and road conditions, substituting mechanical complexity with electronic intelligence.
Solution Approach 2:
The system creates visual copies of the forward blind spot area by capturing images with the camera and processing them to generate detectable representations of obstacles and road conditions, allowing the driver to see what would otherwise be invisible.
3Loss of information
If the processor performs image recognition processing using texture and image feature databases, then the system can identify road conditions and obstacles, but the processing complexity increases
Solution Approach 1:
The system performs preliminary action by pre-storing texture and image feature databases in the processor before actual detection is needed. This allows the processor to quickly compare captured images against known patterns, reducing real-time processing complexity while maintaining high detection accuracy.
Solution Approach 2:
The patent changes parameters by transforming raw image data into recognizable patterns through image recognition processing. The system analyzes texture, color, and structural parameters of captured images to identify road conditions and obstacles, converting complex visual information into actionable detection results.
Data Source
AI summary
An electronic side view mirror warning system includes two cameras, a processor, and a display device. The cameras are mounted on both sides of a front of a vehicle to capture side images of front wheels. The processor is disposed in a cab and stores textures and first image features of road conditions, and second image features of objects. The processor can receive the side images and perform image recognition processing on the side images using the textures, the first image features, and the second image features to obtain a driving road condition information of the vehicle. The display device is disposed in the cab, and can receive and display side images and issue a warning signal. When the driving road condition information indicates that there is a risk within an expected driving range of the vehicle, the processor controls the display device to issue the warning signal.
