Stereo Camera Orientation Control for Remote Mobile Object Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for mobile objects, especially flying objects, face limitations in providing a wide field of view and flexibility in image capture direction, leading to insufficient information for operators, especially in confined or obstacle-rich environments, and fail to simulate a real-time, intuitive control experience.
Innovation Solution
A remote control system equipped with a stereo camera, camera control unit, posture detecting unit, and display unit that allows the camera's image pickup direction to be adjusted based on the operator's line of sight, providing a stereoscopic view by synthesizing camera images with background images and including position information, enabling the operator to have a real-time, intuitive control experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-dimensional camera is fixed on the mobile object with forward direction sighting, then the structure is simple and stable, but the field of view is limited and cannot obtain images in multiple directions
Solution Approach 1:
The patent applies the dynamics principle by making the camera movable rather than fixed. The camera can rotate and tilt to change its sighting direction, allowing it to capture images in multiple directions (forward, backward, left, right, upper, lower) while maintaining a relatively simple overall system structure. This dynamic adjustment capability resolves the contradiction between limited field of view and system complexity.
2Loss of information
If the camera direction is fixed in forward direction, then the device structure is simple, but sufficient information cannot be obtained in confined places or places with many obstacles
Solution Approach 1:
The camera is designed with dynamic directional adjustment capability, allowing it to rotate and tilt to capture images in various directions. This enables the system to obtain sufficient operation information in confined places or places with many obstacles by directing the camera toward relevant areas, while keeping the control system relatively simple through automated or manual directional control.
3Adaptability or versatility
If a fixed three-dimensional camera is used, then the system is simple to operate, but the operator cannot obtain images in wider range needed for flying objects with higher degree of freedom
Solution Approach 1:
The camera system incorporates dynamic directional adjustment that can be controlled remotely, allowing the operator to capture images in a wider range necessary for flying objects with higher degree of freedom. The dynamic control capability enables adaptability to different operational needs while maintaining ease of operation through intuitive control interfaces.
4Adaptability or versatility
If the camera is fixed on the mobile object, then the mounting structure is simple, but the operator cannot change image pickup direction to suit the will of the operator
Solution Approach 1:
The camera mounting system is designed with dynamic adjustment capabilities, allowing the camera to rotate and tilt to change its pickup direction according to operator needs. This dynamic mounting structure enables versatile image capture directions while maintaining relative simplicity through standardized control mechanisms.

AI summary
A remote control system comprises a mobile object, a remote controller for remotely controlling the mobile object, and a storage unit where background images to simulate a driving room or an operation room of the mobile object are stored. The mobile object has a stereo camera, a camera control unit for controlling image pickup direction of the stereo camera, and a first communication unit for communicating information including at least images photographed by the stereo camera. The remote controller has a second communication unit for communicating to and from the first communication unit, a control unit for controlling the mobile object, and a display unit for synthesizing at least a part of the images photographed by the stereo camera and the background images and for displaying the images so that a stereoscopic view can be displayed.
