In-Vehicle Sensor Fusion Display for Object Identification Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems fail to accurately display objects detected by multiple sensors, leading to incorrect identification of separate objects as the same due to differences in detection precision, resulting in inappropriate drive-assisting control in vehicles.
Innovation Solution
An information generation device that acquires sensor information from multiple sensors, determines if objects are in the same area, and generates distinct display information styles to differentiate between detected objects based on predetermined conditions, such as position, direction, and speed, ensuring accurate representation of objects as either separate or the same.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple sensors are used to detect objects, then detection coverage is improved, but object identification accuracy deteriorates due to differences in detection precision
Solution Approach 1:
The patent segments the object identification process by creating distinct display styles for different identification outcomes. The determination unit divides objects into two categories: those satisfying the predetermined condition (identified as the same object) and those not satisfying it (identified as different objects). This segmentation allows the system to handle multiple sensor inputs differently based on their detection results, resolving the contradiction between comprehensive detection and accurate identification.
Solution Approach 2:
The patent applies local quality by assigning different display styles to different identification results. When objects are identified as the same, a first display style is applied; when identified as different objects, a second display style is applied. This localized differentiation in display treatment allows the system to maintain accurate object identification while utilizing multiple sensors with different detection precisions.
2Measurement precision
If objects detected by multiple sensors are displayed separately, then detection precision is maintained, but information accuracy deteriorates due to incorrect identification of same objects as different
Solution Approach 1:
The patent implements feedback through the determination unit that evaluates whether detected objects satisfy the predetermined condition for being identified as the same object. This feedback mechanism uses detection precision as input and produces identification accuracy as output, allowing the system to adjust its display behavior based on the reliability of sensor detections. The feedback loop ensures that objects correctly identified as the same are displayed appropriately, preventing information loss.
Solution Approach 2:
The patent changes the display parameter (display style) based on the determination result. When the predetermined condition is satisfied, the system changes to a first display style indicating same objects; when not satisfied, it uses a second display style indicating different objects. This parameter change in display representation maintains the relationship between detection precision and identification accuracy, resolving the contradiction.
3Ease of operation
If objects are displayed in a unified style, then display simplicity is improved, but object differentiation capability deteriorates
Solution Approach 1:
The patent applies local quality by using different display styles for different identification outcomes. The display control unit locally adjusts the display representation based on the determination result: unified display style for objects identified as the same, differentiated display style for objects identified as different. This localized approach maintains both display simplicity and object differentiation capability.
Solution Approach 2:
The patent segments the display approach into two distinct styles based on object identification results. This segmentation allows the system to maintain simplicity for confirmed same objects while providing differentiation capability when objects are identified as different, resolving the contradiction between display simplicity and differentiation capability.

AI summary
An information generation device comprises a processor that acquires sensor information indicating a measurement result of a detection target area from each of a plurality of sensors having the detection target area that is common to the plurality of sensors, that determines whether or not each of the plurality of sensors detects an object existing in the same predetermined area on the basis of a plurality of pieces of the sensor information acquired, and that generates first display information for separately displaying the object that is detected by each of the plurality of sensors in a case where a determination result is positive and a predetermined condition for determining whether or not a plurality of the objects detected by the plurality of sensors are the same object is not satisfied, and generates second display information for displaying the object detected by each of the plurality of sensors in a display style different from a display style of the first display information in a case where the determination result is positive and the predetermined condition is satisfied.
