Autonomous Route Generation Using 3D Intersection Point Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile apparatuses struggle to recognize and navigate through intersections from different directions due to varying captured images, leading to inefficient route generation and increased movement to learn autonomous paths.
Innovation Solution
An information processing apparatus with a registration unit and a route generation unit that registers and generates routes based on first and second point information, utilizing a communication terminal to transmit user operation information and teach points, allowing the mobile apparatus to recognize intersections as the same place even when approached from different directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile apparatus uses image recognition based on front-back direction only, then the system complexity is reduced, but the apparatus cannot recognize intersections when approached from different directions
Solution Approach 1:
The patent applies dimensionality change by transitioning from 2D image recognition to 3D spatial coordinate-based recognition. Instead of relying solely on image patterns from front-back directions, the system introduces three-dimensional coordinate information (north-south, east-west, up-down directions) to represent spatial positions. This allows the mobile apparatus to recognize intersections from any approach direction by comparing spatial coordinates rather than just image patterns, thereby improving adaptability while managing system complexity through mathematical coordinate transformations.
2Manufacturing precision
If the mobile apparatus learns routes by actual movement through all points, then the route accuracy is improved, but the time and movement required for route generation increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a coordinate system and registering spatial information of all points in the environment before actual route execution. The system performs preliminary mapping by recording three-dimensional coordinates of intersections and destinations in advance, creating a virtual spatial model. When generating routes, the system directly calculates optimal paths using these pre-registered coordinates without requiring the mobile apparatus to physically traverse and learn each point sequentially, thereby significantly reducing route learning time while maintaining high accuracy.
3Loss of information
If the mobile apparatus traverses extensively to learn the environment, then the completeness of route information is improved, but the movement distance and energy consumption increase
Solution Approach 1:
The patent applies mechanics substitution by replacing physical traversal with computational methods. Instead of using mechanical movement to collect environmental information, the system employs coordinate geometry and spatial mathematics to represent and process environmental data. The mobile apparatus uses three-dimensional coordinate systems to model the environment, allowing complete spatial information to be obtained through coordinate registration and mathematical calculations rather than extensive physical exploration, thereby reducing energy consumption while maintaining information completeness.

AI summary
An information processing apparatus (50) includes a registration unit (501, 56) and a route generation unit (501, 54). The registration unit (501, 56) registers first point information being information on the first point that is a specific position of the mobile apparatus (10) moving according to a user operation and is taught by a point teaching unit (32, 301, 7062, 7065, 7122, 7125) as being to be included in a route for autonomous movement of the mobile apparatus (10). The registration unit (501, 56) registers second point information being information on a second point that is obtained based on the first point. The route generation unit (501, 54) generates the route based on the first point information and the second point information registered by the registration unit (501, 56).
