Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reflectors are applied to the moving body for object detection, then detection reliability is improved, but convenience is deteriorated
Solution Approach 1:
The invention extracts and removes the reflectors (markers) from the detection system. Instead of requiring external markers on objects, the system uses natural features and geometric constraints of the objects themselves for detection, thereby improving convenience while maintaining detection reliability through alternative means
Solution Approach 2:
The detection system enables objects to be detected using their own inherent features rather than requiring additional markers. The object's own geometry, edges, and natural characteristics serve as the detection basis, eliminating the need for external reflectors and improving ease of operation
2Measurement precision
If conventional marker-based detection is used, then object detection accuracy is improved, but system complexity is increased
Solution Approach 1:
The invention removes the marker application step and marker detection algorithms from the system. By using only the object's natural features and geometric constraints, it simplifies the overall system while maintaining detection accuracy through alternative geometric reasoning
Solution Approach 2:
The detection system becomes universal by working with any object that has detectable geometric features, without requiring specific markers. The same detection algorithm can handle various objects based on their inherent geometry, reducing system complexity while maintaining broad applicability

AI summary
To improve convenience in an image processing device that detects entry of a moving object into a target area. The image processing device includes an entry detection unit. The entry detection unit of the image processing device detects the entry of the object into a detection target area on the basis of identification information in the detection target area. The detection target area in the entry detection unit is an area in which the object is to be detected. The specific area in the entry detection unit is information about a part of the object in the detection target area.
