Solution Overview

Problem

Existing technologies fail to accurately accumulate and deform the shape of a projection surface when detecting moving objects in the periphery of a moving body, leading to inaccuracies in map information generation.

Innovation Solution

An information processing device that initializes and updates a detection range in map information using sensor data, incorporating first and second peripheral position information to generate accurate map information, which is then used to appropriately deform the projection surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If position information is accumulated along the trace of a moving object detected by sensor, then the detection range covers the movement path, but the map information becomes inaccurate due to including transient moving objects

Engineering Contradiction:
Improvedetection rangeVSAvoidmap information accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent applies dynamics by making the map information update mechanism adaptive - it dynamically adjusts between accumulating position information (when objects are stationary) and replacing position information (when objects are moving). The system detects whether detected objects are moving or stationary and changes the accumulation strategy accordingly, allowing the map information to be dynamically updated based on the movement state of detected objects.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If position information of moving objects is accumulated continuously, then the detection coverage increases, but the projection surface deformation becomes inappropriate due to inaccurate map data

Engineering Contradiction:
Improveposition information volumeVSAvoidprojection surface deformation accuracy
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent extracts and separates the position information of moving objects from the map information accumulation process. By detecting whether an object is moving or stationary, the system extracts only the position information of stationary objects for accumulation, while excluding or replacing position information of moving objects. This separation ensures that the map information used for projection surface deformation contains only stable, accurate spatial data.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the system detects and accumulates all detected position information, then comprehensive spatial data is obtained, but the map information quality deteriorates due to inclusion of transient objects

Engineering Contradiction:
Improvedetection comprehensivenessVSAvoidmap information reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements feedback by continuously monitoring the movement state of detected objects and using this information to adjust the map information update strategy. The system detects whether an object is moving or stationary, and based on this feedback, decides whether to accumulate or replace position information in the map data structure. This feedback mechanism ensures that only reliable position information from stationary objects is accumulated, while position information from moving objects is handled differently to maintain map reliability.

Inventive Principle:
Principle #23Feedback

AI summary

In one aspect, an information processing device includes a map information generation unit. The map information generation unit initializes a range related to detection by a sensor mounted on a moving body in map information including first peripheral position information that is information of a position of an object located in a periphery of the moving body, and adds second peripheral position information acquired from the sensor to the range.
