Environment Map Accuracy for Autonomous Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for estimating the self-position and orientation of autonomously traveling movable apparatuses face challenges in accuracy due to the material of surrounding objects, particularly materials like glass and translucent plastic that cause significant measurement errors in environment mapping.
Innovation Solution
An information processing apparatus that creates an environment map by acquiring material distribution and sensor measurement values, predicts measurement errors based on material types, and excludes sensor measurement values with high errors to improve map accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If construction data is used as an environment map at a construction site, then an environment map can be created for self-position estimation, but the accuracy of the map is low depending on the material of surrounding objects
Solution Approach 1:
The patent segments the environment map creation process by material type. It identifies and separates measurement data based on the material characteristics of surrounding objects (glass, translucent plastic, etc.), then applies material-specific processing rules to exclude or weight data appropriately, thereby improving overall map accuracy while accounting for material-dependent measurement reliability
Solution Approach 2:
The patent changes the parameter of measurement reliability by introducing material-type as a conditioning variable. It dynamically adjusts the trustworthiness of measurement data based on the identified material type of surrounding objects, allowing the system to compensate for known material-specific sensor errors in self-position estimation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The proposed solution enhances the accuracy of environment mapping and self-position estimation during autonomous travel by effectively mitigating measurement errors caused by certain materials, leading to more reliable navigation.
Implementation Method 1
a measurement value measured by a sensor disposed on the movable apparatus

AI summary
In an information processing apparatus that creates a map of an environment in which a movable apparatus moves, a material distribution in an environment in which the movable apparatus moves is acquired, a measurement value measured by a sensor disposed on the movable apparatus is acquired, and a map of the environment is creating based on the measurement value and the material distribution.
