Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional object alarm devices alert drivers to all detected objects, leading to potential overlook of high-risk targets due to excessive alarm information.
Innovation Solution
An object alarm device with a detecting unit, selecting unit, and alarm information generating unit that identifies and prioritizes still objects with a high contact possibility, minimizing alarm information by selectively alerting the driver to the most critical objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the object alarm device alarms the driver of all detected objects, then the driver is informed of all objects, but the driver may overlook high-risk target objects due to excessive alarm information
Solution Approach 1:
The alarm device segments detected objects into different categories (moving objects and still objects) and applies different alarm strategies to each category. Moving objects trigger alarms while still objects do not, unless they meet specific risk criteria. This segmentation allows the system to reduce overall alarm information while maintaining awareness of critical targets.
Solution Approach 2:
The device applies different alarm characteristics to different object types. Moving objects receive standard alarm treatment, while still objects are evaluated based on additional factors such as vehicle trajectory and contact possibility. This localized quality adjustment ensures that alarm information is tailored to the specific risk profile of each object category.
2Ease of operation
If the device reduces alarm information to only critical objects, then driver attention is improved, but the system complexity increases due to object classification requirements
Solution Approach 1:
The alarm system dynamically adjusts its behavior based on the type of detected object. The selecting unit changes the alarm generation criteria depending on whether the object is moving or still, allowing the system to adapt its complexity level to the specific situation rather than maintaining fixed complex classification logic for all cases.
Solution Approach 2:
The device changes the alarm generation parameters based on object characteristics. For moving objects, the system uses standard detection parameters, while for still objects, it modifies parameters to evaluate contact possibility with the vehicle trajectory. This parameter adaptation reduces the need for complex classification systems while maintaining selective alarm capability.

AI summary
There is provided an object alarm device and an object alarm method, which can surely alarm a driver of a high-risk target object. The object alarm device according to the embodiment includes a detecting unit, a selecting unit and, an alarm information generating unit. The detecting unit detects one or more objects from images captured on a movable body. The selecting unit selects a moving object and a still object from among the objects detected by the detecting unit, in which the still object has a contact possibility with the movable body. The alarm information generating unit generates alarm information on the objects selected by the selecting unit.
