Engineering Contradiction Analysis
1Productivity
If traditional camera calibration methods are used for mobile machines, then calibration can be performed, but the process is inefficient and lacks standardized approach
Solution Approach 1:
The net is pre-configured with location markers at predetermined positions before calibration begins. This preliminary arrangement eliminates the need for complex real-time positioning during calibration, allowing operators to simply place targets on the pre-marked locations, thereby improving efficiency while maintaining simplicity
Solution Approach 2:
The calibration system is divided into distinct components: the net with location markers, the calibration targets with identifiable indicia, and the camera system. This segmentation allows each component to be optimized independently and simplifies the overall calibration process by breaking it into manageable steps
2Measurement precision
If calibration targets are positioned without a standardized layout, then setup is flexible, but calibration accuracy is compromised
Solution Approach 1:
The net comes pre-configured with location markers at predetermined positions that define the standardized layout. This preliminary setup ensures that when calibration targets are placed on these markers, they automatically achieve the correct standardized arrangement, guaranteeing calibration accuracy without requiring complex configuration steps
Solution Approach 2:
The location markers on the net serve as self-aligning guides that automatically indicate the correct positions for calibration targets. The system is self-configuring in the sense that the predetermined layout on the net inherently provides the standardized arrangement needed for accurate calibration, eliminating the need for external alignment tools or complex setup procedures

AI summary
A camera calibration tool for calibrating one or more cameras of a mobile machine comprising calibration targets and a net. Each of the calibration targets comprises identifiable indicia. The net is adapted to be coupled to the mobile machine. The net has one or more configurations that define predetermined target locations, with location markers, in a predetermined layout. The calibration targets are positioned respectively at the predetermined target locations in the predetermined layout to calibrate the one or more cameras by use of the calibration targets.
