Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The recognition accuracy and range of binocular stereo vision devices are limited due to fixed lens spacing and hardware limitations, particularly affecting the distance between the two lenses, leading to suboptimal performance when objects are close or far from the lenses.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the distance between the two lenses is fixed, then the device structure is simple, but the recognition range and accuracy are limited
Solution Approach 1:
The patent applies the dynamics principle by making the distance between the two acquisition units adjustable rather than fixed. The adjustment mechanism allows the baseline distance to be dynamically changed based on the depth distance of the measured object, enabling the system to adapt to different measurement scenarios and improve recognition accuracy across various ranges.
Solution Approach 2:
The patent implements parameter changes by varying the baseline distance (distance between lenses) according to the depth distance of the measured object. The processing unit calculates the standard distance based on depth information and generates control signals to adjust the baseline parameter, thereby optimizing recognition accuracy for objects at different distances.
2Adaptability or versatility
If the distance between the two lenses is increased, then the recognition range is extended, but the device size increases
Solution Approach 1:
The adjustment mechanism enables the baseline distance to be dynamically extended or reduced based on measurement requirements. When measuring distant objects, the baseline can be extended to increase recognition range. When measuring close objects or when portability is needed, the baseline can be reduced, thus avoiding permanent increase in device size while maintaining adaptability.
Solution Approach 2:
The adjustment mechanism is divided into independent functional components including the first acquisition unit, second acquisition unit, adjustment mechanism, sensor, and processing unit. This segmentation allows the baseline distance to be modified without redesigning the entire device structure, enabling flexible adaptation to different measurement ranges while maintaining a compact overall design.
3Measurement precision
If the baseline distance is adjusted for different depth distances, then recognition accuracy improves, but the adjustment mechanism complexity increases
Solution Approach 1:
The system implements feedback by using the sensor to acquire the depth distance of the measured object, the processing unit to calculate the standard baseline distance based on this depth information, and then generating control signals to adjust the baseline accordingly. This closed-loop feedback mechanism automates the adjustment process, improving recognition accuracy without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The adjustment mechanism operates autonomously based on depth distance information from the sensor and calculation from the processing unit. The system self-adjusts the baseline distance without external intervention, performing the optimization automatically based on real-time measurement conditions, thereby simplifying the overall control complexity.
