Calibration Target Mount for Stereo Camera Systems

Product Specifications

Technical details and manufacturing context for Calibration target mount

Definition

A precision mounting component within a Stereo Camera Array that provides stable, repeatable positioning of calibration targets (such as checkerboards or dot patterns) during camera calibration procedures. It ensures the target remains fixed at known distances and orientations relative to the camera pair, enabling accurate calculation of intrinsic and extrinsic camera parameters. The mount is typically constructed from aluminum alloy (grade 6061-T6) or stainless steel, offering a balance of rigidity, corrosion resistance, and weight. It features a load capacity of 5–20 kg, positioning accuracy of ±0.05 mm (per ISO 230-2), flatness of 0.02 mm (per ISO 1101), and operates within -10 to 50 °C and 10–90% relative humidity (non-condensing). The mount provides ingress protection rated IP54–IP65 (per IEC 60529) for industrial environments. Surface finish is Ra 1.6 (per ISO 1302) to minimize reflections. Mounting interfaces include M6–M12 threads (per ISO 965) for tripod or frame attachment. The weight of the mount itself ranges from 1.5 to 3.0 kg depending on configuration. This component is essential for ensuring the accuracy of stereo vision systems in applications such as robotics, autonomous vehicles, and industrial inspection. It is a passive mechanical part, requiring no power or electronics. The mount is designed for repeated use, with maintenance limited to cleaning and checking for wear or deformation. For specific applications, users must verify that the mount's specifications meet their requirements, and confirm compliance with relevant standards with the legal manufacturer or supplier.

Working Principle

The mount physically secures the calibration target using clamps, brackets, or magnetic attachments. It maintains the target's position during calibration sequences, allowing cameras to capture multiple images of the target from different angles. This stable reference enables software algorithms to compute camera lens distortion, focal length, and stereo alignment parameters. The mount's rigid construction and precise machining ensure that the target remains planar and at a known orientation, which is critical for accurate calibration. The mounting interface allows for integration with tripods or frames, and the adjustable features enable fine positioning. The mount is designed to be robust and repeatable, with tolerances that ensure consistent results across multiple calibration sessions.
