Innovation Solution
A three-dimensional depth perception apparatus with a synchronized trigger module, MIPI receiving/transmitting module, and multiplexing core computing module that allows selection between monocular and binocular structured light depth perception modes, enabling flexible operation and real-time high-resolution depth map generation through pre-processing, block matching disparity computation, and post-processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If monocular mode is used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The system dynamically switches between monocular and binocular modes based on application requirements. The processor can adaptively select the appropriate depth perception mode, allowing the device complexity to be adjusted while maintaining the capability for high precision when needed.
2Measurement precision
If binocular mode is used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The depth perception processor is designed to perform multiple functions - it can operate in both monocular and binocular modes, and can process both structured light patterns and natural images. This multi-functionality allows a single device to provide high precision depth measurement when needed while maintaining simplicity for basic applications.

AI summary
A three-dimensional depth perception apparatus includes a synchronized trigger module, an MIPI receiving/transmitting module, and a multiplexing core computing module, a storage controller module, a memory, and an MUX selecting module. The synchronized trigger module is for generating a synchronized trigger signal transmitted to an image acquiring module; the MIPI receiving/transmitting module is for supporting input/output of the MIPI video streams and other formats of video streams; the multiplexing core computing module is for selecting a monocular structured or a binocular structured light depth perception working mode. The apparatus flexibly adopts a monocular or binocular structured-light depth sensing manner, so as to leverage the advantages of different modes: the MIPI in, MIPI out working manner is nearly transparent to the user, so as to facilitate the user to employ the apparatus, directly obtaining the depth graph.
