Blind Spot Detection Using Occluding Area Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems fail to appropriately notify drivers of blind spots due to reliance on occluding ratios, leading to unnecessary disturbances and inefficiencies in alerting drivers to occluded objects.
Innovation Solution
An information processing apparatus with a determination unit and output control unit that identifies occluded objects within a blind spot and outputs relevant information, utilizing sensors and image processing to determine the presence of occluded objects and control the output of alerts, ensuring accurate and timely notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification is performed based on occluding ratios, then the system can provide blind spot information, but the notification accuracy deteriorates and causes unnecessary disturbances
Solution Approach 1:
The patent changes the notification parameter from occluding ratio to occluding area. Specifically, it notifies the driver when the occluding area exceeds a predetermined threshold (e.g., 0.5 square meters), rather than using a ratio-based metric. This parameter change enables more accurate blind spot detection and reduces false notifications, directly resolving the contradiction between notification accuracy and unnecessary disturbances.
2Loss of information
If the system notifies all occluded objects, then comprehensive blind spot information is provided, but driver disturbance increases
Solution Approach 1:
The patent applies local quality by evaluating each occluded object individually based on its occluding area. Instead of uniform notification for all occluded objects, the system selectively notifies only those objects whose occluding area exceeds the predetermined threshold. This localized evaluation approach ensures comprehensive information about significant blind spot objects while filtering out minor obstructions that would cause unnecessary disturbance.
3Measurement precision
If notification threshold is lowered to increase detection sensitivity, then more blind spot objects are detected, but false alerts increase
Solution Approach 1:
The patent establishes an appropriate notification threshold for occluding area that balances detection sensitivity and alert accuracy. By using area-based measurement with a predetermined threshold (e.g., 0.5 square meters), the system achieves both high sensitivity in detecting relevant blind spot objects and high reliability in avoiding false alerts, resolving the contradiction between detection sensitivity and alert accuracy.

AI summary
An information processing apparatus according to an embodiment includes a determination unit and an output control unit. The determination unit determines whether a particular part related to a type of an object is included in a blind spot of an object of interest. The output control unit outputs output information when it is determined that the part is included in the blind spot.
