Vehicle Camera Speed Bump Detection Using License Plate Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle navigation systems fail to accurately identify speed bumps in real-time, especially if the navigation data is outdated, and may misidentify or fail to detect speed bumps without clear patterns.
Innovation Solution
A vehicle equipped with a camera and controller that analyzes image data from the camera to identify changes in the height of a front vehicle's license plate over time, using reference image data to determine the presence and position of speed bumps, and adjusts driving speed accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation data is used to identify speed bumps, then speed bump information can be obtained, but the information may not be accurate when navigation is not updated in real-time
Solution Approach 1:
The system uses the camera to continuously capture images of the road ahead and compares detected speed bump patterns with navigation data, creating a feedback loop that verifies and corrects speed bump information in real-time, ensuring accuracy even when navigation data is not freshly updated
Solution Approach 2:
The vehicle's own camera system performs the speed bump detection function, making the system self-sufficient for real-time detection without relying solely on external navigation updates, thereby eliminating the dependency on navigation update timing
2Reliability
If pattern analysis of images is used to identify speed bumps, then real-time detection is possible, but speed bumps without clear patterns or with erased patterns cannot be identified
Solution Approach 1:
The system combines multiple detection approaches (pattern recognition, height analysis, and navigation data correlation) into a single universal detection framework, allowing the camera system to identify speed bumps through various methods depending on pattern clarity, thereby improving reliability without requiring separate specialized systems
3Measurement precision
If multiple detection methods are combined to improve speed bump identification accuracy, then detection reliability improves, but system complexity increases
Solution Approach 1:
The patent merges pattern recognition, height measurement, and navigation data into a unified speed bump detection system where the camera captures images that are processed through multiple analysis methods simultaneously, combining these detection approaches to achieve precise speed bump identification and positioning while managing system complexity through integrated processing

AI summary
A vehicle may include a camera; a storage; and a controller electrically connected to the camera and the storage. The controller may be configured to obtain a front image of the vehicle from the camera by controlling the camera, in a response to obtaining the front image, to identify image data corresponding to a license plate of a front vehicle positioned in front of the vehicle from the front image, to identify a decrease in a distance between the vehicle and the front vehicle based on the image data and reference distance information corresponding to at least one reference image data of at least one reference license plate stored in the storage, to identify a change in height of the license plate of the front vehicle based on the image data, and based on the decrease in the distance between the vehicle and the front vehicle and the change in height of the license plate of the front vehicle, to identify a speed bump located in front of the vehicle.
