Vehicle Image Processing for Parking Block Contact Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems may fail to prevent contact between a vehicle and parking blocks due to considerations only of the block's height, neglecting variations in vehicle load and ground clearance.
Innovation Solution
An image processing system that includes a processor configured to detect obstacles, determine ground clearance, assess potential contact between the vehicle and obstacles, and output warnings to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If vehicle control is performed considering only the height of the parking block, then the control system is simple, but the reliability of preventing contact between the vehicle body and parking block deteriorates
Solution Approach 1:
The system performs preliminary detection of ground clearance and parking block height before contact occurs. The image processing unit captures images and calculates ground clearance in advance, allowing the system to predict potential contact situations before they happen, enabling preventive action rather than reactive control.
Solution Approach 2:
The system introduces an intermediary calculation process that considers both the parking block height and the vehicle's ground clearance. By calculating the difference between these two parameters, the system creates a safety margin indicator that mediates between the simple block height measurement and the complex vehicle state, providing a reliable basis for contact prevention.
2Reliability
If ground clearance detection is added to obstacle detection, then the reliability of contact prevention is improved, but the device complexity increases
Solution Approach 1:
The system merges the obstacle detection function with the ground clearance detection function into a single image processing unit. By using the same camera and image processing algorithms for both purposes, the system avoids duplicating detection hardware, thereby reducing overall device complexity while maintaining improved reliability through comprehensive measurement.
Solution Approach 2:
The image processing unit is designed with multi-functionality, serving both to detect obstacles (parking blocks) and to measure ground clearance. This universal component performs multiple functions using the same hardware resources, eliminating the need for separate detection systems and reducing overall system complexity.

AI summary
Provided is an image processing system that is capable of preventing contact between an obstacle and a movable apparatus regardless of the state of the movable apparatus, comprising an obstacle information acquisition unit configured to detect a position and a height of an obstacle in a traveling direction of a movable apparatus, a ground clearance detection unit configured to detect the ground clearance, which is the height from the ground surface in the traveling direction of the movable apparatus to the movable apparatus, a contact determination unit configured to determine whether or not the movable apparatus and the obstacle will come into contact with each other in the traveling direction of the movable apparatus based on the position and height of the obstacle and the ground clearance, and a warning output unit configured to output a warning in a case in which it has been determined by the contact determination unit that contact will occur.
