Vehicle Attitude Detection Using Target Reference and Position Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing techniques for calibrating and detecting the attitude and position of multiple detectors on vehicles are time-consuming and cumbersome, especially when dealing with different types of detection systems, which affects the accuracy of driver assistance and autonomous driving systems.
Innovation Solution
An attitude/position detection system that includes targets and a change mechanism to adjust the vehicle's position relative to these targets, allowing the attitude/position detection device to maintain the vehicle's position for a predefined period and use detection results from targets to efficiently detect the attitude/position of each detector, thereby improving detection accuracy and reducing the time required for calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple detectors are calibrated using existing techniques, then detection accuracy can be improved, but the calibration process becomes time-consuming and cumbersome
Solution Approach 1:
The system performs preliminary positioning by moving the vehicle to a predetermined position before calibration begins. The attitude/position detection device then maintains this position for a predefined period to establish a stable reference frame, allowing subsequent detector calibration to proceed more efficiently without repeated repositioning
Solution Approach 2:
The attitude/position detection device serves multiple functions: it detects the position of targets, determines vehicle attitude, maintains vehicle positioning, and provides reference data for multiple detector calibrations. This multi-functional approach eliminates the need for separate calibration procedures for each detector type
2Measurement precision
If different types of detection systems are calibrated separately, then each system can be optimized, but the overall calibration process becomes cumbersome and time-consuming
Solution Approach 1:
The system combines multiple detector calibrations into a single integrated process. The attitude/position detection device provides a unified reference framework that simultaneously calibrates various detector types (cameras, LIDAR, radar) by comparing their readings against the maintained vehicle attitude and target positions, eliminating the need for separate calibration procedures

AI summary
In an attitude/position detection system for detecting an attitude/position of at least one detector mounted to a vehicle, at least one target is used to detect the attitude/position of the at least one detector. A change mechanism is configured to change a position of the vehicle relative to the at least one target. An attitude/position detection device is configured to control the change mechanism to maintain the position of the vehicle relative to the at least one target for a predefined period of time, and detect the attitude/position of the at least one detector using a result of detection of the at least one target by the at least one detector.
