Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detection devices in autonomous systems may output erroneous results if not operating normally, posing a risk for accidents, as existing methods lack effective means to determine their operational status in real-time.
Innovation Solution
A method and device that compare positional data of objects detected by a primary detection device with a calibrated reference detection device, extracting a common object within a predetermined time range to assess the primary device's normal operation, and output signals for calibration or safety protocols as needed.

Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If detection devices are used in autonomous systems, then detection capability is improved, but reliability deteriorates because the devices may output erroneous results when not operating normally
Solution Approach 1:
The patent introduces a determination device as an intermediary component that mediates between the detection device and the autonomous system. This determination device continuously monitors the operational status of the detection device by analyzing detection results and comparing them against expected patterns, thereby providing a reliability layer that separates the detection function from the control system and prevents erroneous results from causing accidents.
Solution Approach 2:
The patent implements a feedback mechanism where the determination device continuously analyzes detection results and provides feedback about the operational status of the detection device. When abnormal detection results are identified, the system generates alerts or warnings to indicate potential failures, enabling real-time monitoring and response to maintain system reliability without compromising detection capability.
2Reliability
If real-time determination of detection device status is implemented, then safety is improved, but device complexity increases
Solution Approach 1:
The determination device is designed with multi-functionality to reduce overall system complexity. It performs multiple tasks including analyzing detection results, determining operational status, generating safety alerts, and providing feedback to the autonomous system. By consolidating these functions into a single universal component rather than separate specialized systems, the patent achieves real-time safety monitoring without proportionally increasing device complexity.

AI summary
A determination method includes: obtaining first information indicating positions and shapes of one or more objects detected by a first detection device, and second information indicating positions and shapes of one or more objects detected by a second detection device determined in advance as a reference detection device; extracting a reference object that is a common object from the one or more objects detected by the first detection device and the one or more objects detected by the second detection device based on the first information and the second information, the common object being detected by the detection devices with a time difference within a predetermined range; comparing a position of the reference object indicated by the first information to the position of the reference object indicated by the second information; and determining whether the first detection device is operating normally.
