Object Detection Identicality Determination for Nearest Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple object detectors are used, accurate determination of identicality between objects detected by different detectors can be impossible, leading to false identification of the nearest object ahead, especially when one detector detects multiple objects in a direction and another detects a single object in the same direction.
Innovation Solution
An object detection apparatus with a first detector, a second detector, and an identicality determiner that determines object identicality by setting a predetermined distance criterion based on the distance to the nearest object ahead, considering the detection accuracy of each detector, to ensure accurate identification of the nearest object even when detectors differ in the number of objects detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple object detectors are used to detect objects in the same direction, then the detection coverage and reliability are improved, but the accuracy of determining object identicality deteriorates when detectors report different numbers of objects
Solution Approach 1:
The patent introduces a third detector as an intermediary to mediate between the first and second detectors. This third detector provides additional detection data that helps resolve conflicts when the first and second detectors report different numbers of objects. By comparing detection results from all three detectors, the system can more accurately determine object identicality and identify the nearest object ahead, thus maintaining high reliability while improving identicality determination accuracy.
2Adaptability or versatility
If one detector detects multiple objects while another detects a single object in the same direction, then the detection versatility is improved, but the ease of determining which objects are identical deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where detection results from multiple detectors are continuously compared and validated. When the first and second detectors report different numbers of objects, the system uses feedback from the third detector and iterative comparison to resolve the discrepancy. This feedback loop automatically handles the complexity of matching objects across detectors with different detection counts, maintaining detection versatility while simplifying the determination process through automated conflict resolution.
3Reliability
If multiple detectors are used to ensure the nearest object is detected without fail, then the detection reliability is improved, but the complexity of the identicality determination system increases
Solution Approach 1:
The patent segments the identicality determination process into distinct stages: first comparing detection results from the first and second detectors, then using the third detector to resolve conflicts when object counts differ, and finally determining the nearest object based on validated data. This segmentation of the determination process into manageable steps reduces system complexity while maintaining high reliability for nearest object detection through the coordinated use of multiple detectors.

AI summary
In an apparatus for detecting and determining identicality of at least one object present within a region around a subject vehicle to be monitored, having a first detector adapted to detect the at least one object, a second detector adapted to detect the at least one object, and an identicality determiner adapted to determine whether the at least one object detected by the first and second detectors are identical, it is configured that the identicality determiner determines that, when the first detector detects the objects in a plural number in a first direction and the second detector detects the object in a single number in a second direction that is same as the first direction, one among the objects ahead and nearest to the subject vehicle detected by the first detector and the object detected by the second detector are identical.
