Camera Position Calibration Using Vehicle Visual Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems require manual training and re-training when moved to a new location, which is time-consuming and inefficient.
Innovation Solution
A monitoring system that automatically determines the position of a camera based on known details of the area to be monitored and the position of assets within the field of view, using visual indicators like QR codes or barcodes on moving vehicles to calibrate the camera's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual training is used to train the camera on what objects to monitor, then the camera can be trained to monitor specific areas, but the training process takes multiple days to complete
Solution Approach 1:
The patent replaces manual mechanical training operations with an automated computer vision system. The system uses image processing algorithms to automatically identify routes, vehicles, and areas of interest, eliminating the need for manual operator training that takes multiple days. The automated system processes visual data from the camera to generate monitoring parameters without human intervention.
2Adaptability or versatility
If the camera is moved to a new location, then the camera can monitor different areas, but the camera requires re-training
Solution Approach 1:
The patent implements a self-service calibration system where the camera automatically determines its own position and training parameters using visual indicators in the environment. When moved to a new location, the camera captures images, detects visual indicators (QR codes, barcodes, or natural features), and autonomously calculates its position and generates appropriate monitoring parameters without requiring operator re-training.
3Extent of automation
If visual indicators like QR codes or barcodes are used on moving vehicles, then the camera position can be automatically calibrated, but the system complexity increases
Solution Approach 1:
The patent introduces visual indicators (QR codes, barcodes, or natural visual features) as intermediary elements that facilitate automatic camera calibration. These indicators serve as mediators between the camera system and the environment, providing recognizable reference points that the computer vision system can detect and use to calculate camera position and orientation without complex direct measurement systems.

AI summary
A method of operating a monitoring system may include receiving details of an area to be monitored, and receiving one of a) position details of an asset moving within a field of view of the area to be monitored, or b) position details of a camera configured to monitor the area. The method may include determining one of c) a position of the camera responsive to receiving the position details of the asset moving within the field of view of the area; or d) a position of the asset moving within the field of view responsive to receiving the position details of the camera.
