Vehicle Object Detection with Pose Prediction Beyond View Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection systems face reduced tracking accuracy when the object moves out of the capture view angle, affecting distance, position, and pose detection.
Innovation Solution
An object detection device comprising a distance detection portion, position detection portion, pose detection portion, and prediction portions that utilize stereo image capture and intervehicle communication to accurately detect and predict the position and pose of objects regardless of view angle or distance, switching between actual detection and prediction results based on object visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image analysis is used to detect orientation and speed of preceding vehicle, then tracking accuracy is improved when object is within view angle, but tracking accuracy deteriorates when object moves out of capture view angle
Solution Approach 1:
The system performs preliminary action by predicting the future position and pose of the preceding vehicle using detected state information (orientation, speed) before the vehicle actually moves out of the capture view angle. This prediction enables the system to maintain tracking accuracy even when the object is no longer visible in the current frame.
Solution Approach 2:
The patent introduces an intermediary mechanism by using state information (orientation, speed, position) as a mediator between direct image analysis and position prediction. When the object moves out of view, this intermediary state information allows the system to continue tracking through prediction rather than direct observation.
2Device complexity
If only image capture device is used for detection, then device complexity is reduced, but detection reliability deteriorates when object is at various distances and view angles
Solution Approach 1:
The patent applies universality by designing a multi-functional detection system that can operate in multiple modes: direct image analysis when the object is within view angle, and prediction-based tracking when the object moves out of view. This universal system maintains high detection reliability across various distances and view angles without requiring multiple specialized devices.
