Solution Overview

Problem

Existing UAV systems cannot reliably specify the orientation of mobile devices in imaging data, especially when speeds are high, making collision avoidance challenging without considering the orientation of obstacles.

Innovation Solution

An information processing device and method that acquires and analyzes imaging data to specify the orientation of mobile devices, including their moving direction, movable direction, and expected direction, using features like propellers or cameras, and predicts their future position and orientation for collision avoidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If imaging data is analyzed to specify orientation of mobile devices, then collision avoidance capability is improved, but processing complexity and time consumption increase

Engineering Contradiction:

Improvecollision avoidance capabilityVSAvoidprocessing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The orientation specification process is segmented into distinct steps: detecting characteristic points on the mobile device, determining the orientation based on these points, and then using this information for collision avoidance. This segmentation makes the complex processing more manageable and efficient.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary analysis of imaging data to specify the orientation of mobile devices before collision avoidance decisions are made. By pre-determining orientations and positions, the system prepares critical information in advance, enabling faster and more reliable collision avoidance responses.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If orientation specification is performed for high-speed moving objects, then collision avoidance reliability is improved, but measurement and detection difficulty increases

Engineering Contradiction:

Improvecollision avoidance reliabilityVSAvoidorientation detection difficulty

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system utilizes characteristic points or features on the mobile device that can be reliably detected in imaging data. By focusing on these distinct features rather than the entire device, the system can accurately determine orientation even when the device is moving at high speeds.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent replaces complex mechanical tracking systems with image processing-based orientation detection. By analyzing the position of characteristic points in imaging data, the system can determine device orientation without requiring sophisticated mechanical sensors or tracking infrastructure.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
