Autonomous Object Learning for Robot Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for a robot to learn objects in its environment require manual marking and prior knowledge of the object's appearance or motion, making it difficult to distinguish between the object and the robot's hand, and necessitate frequent corrections in geometry models when the environment or robot arm changes.
Innovation Solution
An information processing device and method that estimates the foreground state of an image using actual observations and updates background and foreground visibility models, allowing the robot to learn objects autonomously without prior knowledge, and adapt to changes in the environment or robot configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual marking and prior knowledge of object appearance are used, then object identification is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The robot performs autonomous learning of object appearance without external marking or prior knowledge input. The system automatically extracts and stores visual features of objects during interaction, enabling the robot to identify objects independently based on its own observations rather than relying on pre-provided information.
Solution Approach 2:
The system incorporates feedback loops where the robot observes the consequences of its actions on objects, uses this information to refine its understanding of object appearance, and continuously improves its recognition accuracy. This iterative learning process allows the robot to adapt to new objects without manual intervention.
2Measurement precision
If geometry model is used to distinguish hand and object, then object recognition is improved, but adaptability deteriorates when environment or robot configuration changes
Solution Approach 1:
The system dynamically adjusts its object recognition models based on real-time observations and changes in the environment. When the robot detects changes in its own configuration or the environment, it updates its geometric models and appearance data accordingly, allowing continuous adaptation without requiring manual model correction.
Solution Approach 2:
The robot autonomously monitors and adapts its own geometry model based on observations of its hand and object interactions. The system self-corrects by comparing expected versus actual observations and adjusting its internal models, eliminating the need for external intervention when configuration changes occur.
3Productivity
If image trimming based on motion is used, then learning efficiency is improved, but measurement precision deteriorates due to difficulty in distinguishing hand and object
Solution Approach 1:
The system segments the image into multiple regions based on learned object appearance characteristics and spatial relationships. By dividing the image into distinct segments corresponding to different objects and the hand, the system can accurately identify and extract object regions even when motion-based methods struggle to distinguish between the hand and object boundaries.

AI summary
An information processing device includes: a foreground state estimating unit configured to estimate a foreground state of an image using an actual image which is an image to be actually observed; and a visible model updating unit configured to update a background visible model which is visibility of the background of an image and a foreground visible model which is visibility of the foreground using an estimation result of the foreground state.
