Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera calibration requires significant processing and is often unnecessary, making it inefficient to perform regularly.
Innovation Solution
An image processing apparatus that decides whether camera calibration is necessary by comparing images captured at different times and using known objects to determine if calibration parameters need to be updated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera calibration is performed regularly to maintain accurate 3D position and orientation relationships, then measurement precision is improved, but productivity deteriorates due to significant processing time and power consumption
Solution Approach 1:
The patent changes the calibration frequency parameter from regular intervals to event-driven timing. Calibration is triggered only when specific conditions are met (impact detection, temperature change, or lapse of time exceeding threshold), transforming the calibration process from a continuous high-cost operation to a selective low-cost operation while maintaining measurement accuracy when needed
Solution Approach 2:
The system performs self-diagnosis to determine whether calibration is needed by automatically analyzing sensor data (accelerometer, temperature sensor) and image data (known object detection). This self-service mechanism eliminates the need for manual calibration decisions and enables intelligent, condition-based calibration scheduling that balances accuracy with processing efficiency
2Reliability
If camera calibration is performed frequently to account for changes due to impact, temperature, and time, then reliability is improved, but loss of time increases due to repeated processing
Solution Approach 1:
The system performs preliminary monitoring of conditions (impact, temperature, time) continuously in the background without executing full calibration processing. By pre-identifying when calibration conditions are met through sensor thresholds and timers, the system prepares for calibration only when necessary, reducing unnecessary processing time while maintaining reliability
Solution Approach 2:
The patent implements periodic checking of calibration conditions through timers and continuous sensor monitoring, but executes full calibration processing only when conditions warrant it. This periodic monitoring approach maintains system reliability by regularly assessing camera relationship stability while minimizing time loss through selective execution of intensive processing

AI summary
The present disclosure relates to an image processing apparatus, an image processing method, and a program that permit decision as to whether or not calibration of images is necessary.A decision section decides, using a current image captured by a camera and a past image captured by the camera, whether or not it is necessary to calibrate images captured by the camera. The present disclosure is applicable, for example, to a vehicle-mounted camera system that includes an automobile vehicle, two cameras, mounted to a front roof of the automobile vehicle such that imaging regions overlap, and an image processing apparatus, and so on.
