Engineering Contradiction Analysis
1Area of stationary object
If automatic monitoring using cameras is used for recognizing objects in the terminal, then the monitoring coverage is improved, but the recognition precision of object positions and occupied spaces deteriorates
Solution Approach 1:
The patent introduces an intermediary processing system that bridges the gap between camera monitoring and precise position recognition. The server receives images from multiple cameras, processes them through object recognition algorithms, and generates precise position information about objects in the terminal. This intermediary processing layer transforms the raw visual data into structured, precise position information that can be used for autonomous navigation and collision avoidance.
Solution Approach 2:
The patent replaces traditional mechanical or manual monitoring methods with an automated computer vision system. Instead of relying on physical sensors or human operators to detect object positions, the system uses image processing algorithms to automatically identify and track objects, their positions, and their occupied spaces throughout the terminal environment.
2Measurement precision
If the apparatus recognizes occupied spaces of multiple objects including autonomous yard tractors and external vehicles, then the safety distance determination accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal object recognition system that can identify and track multiple types of objects (autonomous yard tractors, external vehicles, containers, and other obstacles) using the same camera network and processing algorithms. The system treats all objects uniformly by detecting their positions and calculating their occupied spaces, regardless of their specific type or function. This multi-functional approach improves safety distance determination without requiring separate specialized systems for each object type.
Solution Approach 2:
The patent segments the complex task of safety distance determination into distinct processing steps: image capture, object detection, position identification, occupied space calculation, and safety distance computation. By dividing the overall system into these functional segments, the complexity is distributed and managed more effectively, allowing each component to focus on a specific aspect of the problem while contributing to the overall safety determination.
