Robot Camera Control Using SLAM for Target Object Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of object recognition in robotic systems depends on the quality of captured images, and existing technologies face challenges in focusing on specific subjects when multiple objects at different distances are present in the same image.
Innovation Solution
A control device that generates a map of the surroundings using sensor data from a moving object and controls a camera's focus and angle of view based on the positional relation between the object and the camera, ensuring the target object is in focus and appears large, utilizing simultaneous localization and mapping (SLAM) technology.

Engineering Contradiction Analysis
1Loss of information
If a camera captures an image of multiple subjects at different distances, then the image contains information about all subjects, but the recognition accuracy decreases because it is difficult to identify which subject to focus on
Solution Approach 1:
The system performs preliminary actions by generating a map of the environment and identifying the target object before image capture. The control device uses sensor data to create a spatial map, determines which object is the target, and then controls the camera to focus on that specific target. This preliminary identification and positioning enables the camera to capture images with the target in focus, thereby maintaining high recognition accuracy while preserving information about multiple subjects in the scene.
2Measurement precision
If the camera focuses on a distant target object, then the target object appears larger and clearer, but nearby objects become out of focus and less visible
Solution Approach 1:
The system applies local quality by optimizing the image capture parameters specifically for the target object's location and characteristics. Based on the map information and target object position, the control device adjusts the camera's focus distance and angle of view to ensure the target object is captured with high clarity and appropriate size. This localized optimization for the target object enables precise focus and clear imaging of the distant target while accepting that nearby objects may be out of focus, as they are not the primary subject of interest.

AI summary
The present technology relates to a control device, a control method, and a program that enable capturing an image suitable for use in image processing such as recognition of a target object. A control device according to an embodiment of the present technology generates a map including a target object existing around a moving object on the basis of output from a sensor provided on the moving object, and controls drive of a camera provided on the moving object that captures an image of the target object on the basis of a relation between a position of the target object and position of the moving object on the map. The present technology can be applied to a robot capable of acting autonomously.
