Stereo Camera Array for 3D Pattern Scanners

Product Specifications

Technical details and manufacturing context for Stereo Camera Array

Definition

Within a 3D Pattern Scanner, the Stereo Camera Array serves as the primary optical sensing module. It consists of precisely calibrated cameras arranged in a specific geometric configuration to simultaneously capture multiple 2D images of a target object or pattern. By analyzing the parallax differences between these synchronized images, the system reconstructs detailed 3D surface geometry, depth maps, and spatial relationships, forming the foundational data for subsequent pattern analysis, measurement, and digital modeling processes.

The array typically includes 2 to 8 cameras with a baseline distance (distance between optical centers of adjacent cameras) ranging from 50 to 200 mm. Frame synchronization accuracy is maintained within ±0.1 microseconds to ensure consistent capture across all cameras. The field of view overlap between adjacent cameras is 60–90%, which is critical for accurate depth computation. Each camera offers a resolution of 5–12 megapixels and supports frame rates from 30 to 120 fps, depending on the application's need for capturing fast-moving objects versus bandwidth constraints.

Constructed with optical-grade glass lenses, an aluminum alloy housing, CMOS/CCD image sensors, and precision mounting brackets, the array is designed for industrial environments. It operates within a temperature range of -10°C to 50°C and has an ingress protection rating of IP54–IP65 (per IEC 60529) to resist dust and water. Power consumption is 5–15 W for all cameras and the processing unit. Interfaces include GigE and USB3.0 for data transfer and control. The weight ranges from 1.5 to 4.0 kg, depending on the number of cameras and housing material. Lens mounts are available in C and CS types for compatibility with standard lenses.

All listed parameters are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application. The array is a component intended for integration into a complete scanning system; it is not a standalone product. Proper calibration and configuration are essential for achieving accurate 3D reconstruction.

Working Principle

The Stereo Camera Array operates on the principle of stereoscopic vision and triangulation. Multiple cameras with known positions and orientations capture synchronized images of the same scene. Image processing algorithms then identify corresponding points across these images. By calculating the disparity (positional difference) of these matched points and applying geometric calibration data, the system computes precise 3D coordinates for each point, effectively transforming 2D pixel data into a 3D point cloud or depth map that represents the scanned object's surface topology.

Frequently Asked Questions

What is the typical number of cameras in a Stereo Camera Array?

The array typically contains 2 to 8 cameras, depending on the configuration and application requirements. The exact number should be confirmed with the manufacturer for the specific model.

What is the baseline distance and why is it important?

The baseline distance is the distance between optical centers of adjacent cameras, ranging from 50 to 200 mm. It affects depth accuracy and the field of view overlap. Larger baselines generally improve depth resolution but may reduce overlap.

What interfaces are available for data transfer?

The array supports GigE and USB3.0 interfaces for data transfer and control. The choice depends on the integration requirements and data bandwidth needs.

What is the operating temperature range?

The array operates within -10°C to 50°C. Outside this range, image quality may degrade. Always verify the specific model's environmental specifications with the manufacturer.
