Vehicle Observation Control for Conflicting Object Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing observation devices struggle to provide clear and appropriate notifications to vehicles when multiple detection devices yield conflicting recognition results for objects in the observation area, leading to driver confusion.
Innovation Solution
An observation device comprising multiple detection devices and a controller that determines a unified notification recognition result by combining and processing the recognition results from these devices, using decision tables to ensure consistent and attention-grabbing notifications based on object type, speed, and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple detection devices are used to recognize objects, then the reliability of object detection is improved, but the complexity of processing recognition results increases
Solution Approach 1:
The patent segments the recognition result processing by dividing objects into different categories (pedestrian, vehicle, animal, other) and applying different notification strategies to each category. This segmentation allows the system to handle complex multi-device recognition results in a structured manner, improving reliability without overwhelming complexity.
Solution Approach 2:
The patent performs preliminary classification of recognition results before final notification. The controller pre-processes recognition results by categorizing objects and determining notification priorities in advance, which simplifies the subsequent notification process and reduces the complexity of real-time decision-making.
2Measurement precision
If multiple detection devices are used to recognize objects, then the accuracy of object recognition is improved, but the confusion in notification information increases
Solution Approach 1:
Instead of notifying drivers of all possible recognition results from multiple devices (which would cause confusion), the patent inverts the approach by selecting and prioritizing the most critical recognition results. The system notifies drivers of high-priority objects first, and only notifies of lower-priority objects if high-priority objects are not detected, thereby maintaining notification clarity while utilizing multiple detection devices for improved accuracy.
Solution Approach 2:
The patent applies different notification qualities to different object categories. Critical objects like pedestrians and vehicles receive immediate, prominent notifications, while less critical objects like animals receive notifications only when no critical objects are detected. This local differentiation of notification quality maintains information clarity while leveraging multiple detection devices for comprehensive accuracy.
3Speed
If notification is issued based on single detection device result, then the response speed is improved, but the reliability of notification is reduced
Solution Approach 1:
The patent performs preliminary processing of recognition results from multiple detection devices, categorizing objects and determining notification priorities before the actual notification is issued. This pre-processing step enables the system to quickly determine what to notify about without sacrificing reliability, as the heavy lifting of analyzing multiple recognition results is done in advance.
Solution Approach 2:
The patent segments the notification process into different priority levels and object categories. By organizing recognition results into structured categories with assigned priorities, the system can rapidly retrieve and notify about the most critical objects without needing to process all recognition results in detail, thus maintaining both speed and reliability.

AI summary
Provided are an observation device and an observation method that can issue an appropriate notification to a vehicle even when recognition results of multiple detection devices are different from each other. An observation device (5) is configured to issue a notification to a vehicle. The observation device (5) includes a first detection device (50-1), a second detection device (50-2), and a controller (53). The first detection device (50-1) is configured to recognize an object present in an observation area. The second detection device (50-2) is configured to recognize the object present in the observation area. The controller (53) is configured to determine a notification recognition result based on a combination of a recognition result for the object produced by the first detection device (50-1) and a recognition result for the object produced by the second detection device (50-2), the notification recognition result being a recognition result for the object to be included in the notification.
