Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D camera devices have a limited range of three-dimensional effects due to a fixed distance between twin cameras, restricting the clarity and quality of 3D images.
Innovation Solution
A three-dimensional sensing device with a movable second camera driven by a mechanism that adjusts its position relative to a fixed first camera, allowing for a larger range of depth sensing by overlapping fields of view, facilitated by a driving member and distance sensing unit to capture images from slightly different angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between twin cameras is fixed, then the device structure is simple, but the range of three-dimensional effects is narrow
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed camera distance into an adjustable one. The second camera is mounted on a movable platform that can shift along the optical axis under motor control, enabling the baseline distance between the two cameras to be dynamically adjusted. This allows the device to adapt to different depth sensing requirements while maintaining a relatively simple overall structure through automated control mechanisms.
2Measurement precision
If the distance between twin cameras is fixed, then the device structure is stable, but the clarity and quality of 3D images is limited
Solution Approach 1:
The patent implements parameter changes by allowing the baseline distance between cameras to be adjusted according to different depth sensing requirements. The movable platform enables continuous adjustment of the second camera's position along the optical axis, changing the spatial parameter of camera separation. This parameter adjustment optimizes the parallax effect for different object distances, thereby improving 3D image clarity and expanding the depth sensing range.
3Adaptability or versatility
If the second camera position is adjustable, then the range of depth sensing is extended, but the device complexity increases
Solution Approach 1:
The patent reduces mechanical complexity by replacing manual adjustment mechanisms with an automated motor-driven system. The movable platform is equipped with a motor that automatically positions the second camera according to control signals, eliminating the need for complex manual adjustment mechanisms. This substitution maintains the extended depth sensing range while simplifying the overall device structure through automated control.

AI summary
A three-dimensional image-capturing device includes a first camera, a second camera, a driving member and a sensing member. The second camera is at one side of the first camera and is capable of being moved laterally by the driving member. After depth-sensing and establishing orientations in an image, the driving member is able to drive the second camera to move relative to the first camera, to change a distance between the first camera and the second camera. Such relative movement allows a greater range of three dimensionality for face recognition and other purposes.
