Vehicle Position-Based Important Region Specification

Solution Overview

Problem

Existing methods for setting important regions in videos taken by cameras are inadequate, particularly when the vehicle's traveling direction is uncertain or the video is blurred, leading to inappropriate region specification.

Innovation Solution

An important region specification system that acquires vehicle position information and specifies important regions within the camera's image-capturable area based on this information, notifying an image processing apparatus to enhance image quality and object recognition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a region is set based on the traveling direction of the vehicle, then the region specification is simplified, but the region cannot be appropriately set when the traveling direction is uncertain

Engineering Contradiction:

Improveregion specification simplicityVSAvoidregion specification accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces an important area specification unit as an intermediary component that receives both vehicle position information and video data. This unit independently determines important areas based on position data without requiring interpretation of vehicle direction from video, thus resolving the contradiction by decoupling the region specification process from uncertain direction detection while maintaining simplicity and improving reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the video processing into independent functional units: video acquisition, position information acquisition, important area specification, and image processing. The important area specification unit operates independently using position information, separating the region determination function from the video analysis function, thereby ensuring accurate region specification regardless of video clarity or direction uncertainty

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If region setting relies on video analysis, then visual context is utilized, but the region cannot be appropriately set when the video is blurred

AI summary

In order to appropriately specify an important image region in a video, an important region specification system (1) includes: an information acquisition means (11) for acquiring position information of a vehicle; an important region specification means (12) for specifying an important region in an image-capturable region of a camera based on the position information of the vehicle; and an important region notification means (13) for notifying an image processing apparatus, which processes an image taken by the camera, of the important region.
