Unlike traditional vision systems that rely on PCs or cloud servers, embedded vision emphasizes low latency, low power consumption, high reliability and edge intelligence – making it the core technological pillar for autonomous perception in robotics, drones, intelligent surveillance, industrial inspection and edge AI devices.

As AI computing power shifts to the edge, embedded vision is evolving from a passive “capture+transmit” model to an active “capture+process+decide” intelligent paradigm. This transformation places new demands on vision hardware: beyond excellent image quality, it must achieve seamless collaboration with edge computing platforms (such as Jetson, RK3588, Raspberry Pi, etc.) under multiple constraints including form factor, power consumption, interface compatibility, and environmental robustness.

Against this backdrop, stereo vision modules and ultra-thin board-level cameras have become the two most core and edge-optimized hardware forms in embedded vision. Stereo modules endow machines with depth perception – ideal for SLAM navigation, obstacle avoidance, and 3D metrology; board-level cameras, with their extreme miniaturization and low power consumption, provide a highly integrated vision interface for space-constrained mobile devices.

I. Stereo Modules – Endowing Machines with Stereoscopic Vision

Stereo vision mimics the human visual system by capturing the same scene from two different viewpoints and computing depth from disparity. MindVision's stereo camera modules are purpose-built for stereoscopic vision and depth sensing, available in both USB3.0 and GigE interface series.

Key Advantages

• Microsecond-level hardware synchronization: Supports continuous, software-trigger, and hardware-trigger operating modes; both left and right images are automatically synchronized with synchronization error in the microsecond range. This ensures strict left-right alignment, delivering clear depth maps even in fast-motion scenes, avoiding ghosting and depth-calculation errors caused by sync drift.
• Flexible customization: Sensor board size can be customized per customer requirements; FPC cable length is replaceable; baseline is adjustable. For close range (<2m), a 5-10cm baseline is recommended; for long range (5-10m), 20-30cm is suggested. MindVision supports on-demand customization.
• Lossless RAW output: Supports 8-bit, 12-bit and 16-bit lossless grayscale output, preserving complete image data for AI algorithms. Unlike UVC-based stereo modules on the market, MindVision employs a dedicated SDK that supports higher pixel counts with no theoretical upper resolution limit – better suited for mid-to-high-end 3D applications.
• Rich interfaces and expansion: Modules reserve 2 RS232 ports, 1 GPIO, 1 strobe output, and 1 hardware trigger input, all customizable. The on-board RS232 can be used to control other components, simplifying system design and reducing cost.
• Cross-platform compatibility: Provides dedicated SDK and drivers supporting Windows, Linux, ARM Linux, and macOS, fully compatible with MindVision's single-camera SDK. Supports development languages including C/C++/C#/VB6/VB.NET/Delphi/Java/Labview, with abundant demos; compatible with vision software such as Halcon, VisionPro, and OpenCV.

III. Typical Application Scenarios

Scenario 1: Autonomous Mobile Robot SLAM Navigation and Obstacle Avoidance

Task Description: AGVs/AMRs or service robots use visual odometry (VIO) and SLAM for autonomous localization and navigation. They must capture environmental features in real time, compute poses quickly, and identify obstacles for collision avoidance.

Why choose a stereo module: Stereo modules naturally provide disparity-based depth information, delivering dense depth maps without additional structured light or LiDAR. MindVision's microsecond-level synchronization ensures strict left-right alignment, giving VIO/SLAM algorithms high-accuracy depth data. The 130fps high frame rate handles rapid rotation and movement, while the global shutter eliminates motion distortion, making feature-point extraction more reliable during fast motion.

Typical Configuration: MV-MSU133GC/M2-T stereo module + NVIDIA Jetson Orin / RK3588 edge computing platform. The reserved GPIO and trigger inputs synchronize fill-lights or encoders. The product has been successfully deployed in ROS-based robot navigation systems and visual SLAM projects.

Value: No external depth sensor needed – a single stereo module simultaneously handles localization, mapping and obstacle avoidance, significantly reducing system cost and power consumption.

Scenario 2: Industrial 3D Metrology and Defect Inspection

Task Description: On production lines, perform 3D dimensional measurement, surface defect detection, or assembly verification on workpieces – requiring high precision, high repeatability, and fast response.

Why choose a stereo module or high-resolution board-level camera: For 3D profiling, a stereo module (or stereo structured-light module) captures workpiece point-cloud data in a single shot via disparity. MindVision's stereo products support lossless RAW output, preserving full image data for high-precision 3D reconstruction.
