Hikvision II QR Code Calibration Board Product Features: Micron-level high precision, high contrast, non-reflective, clear and easy to identify, High precision (with a maximum accuracy of 1um),supports multi-format drawing customization Applicable scenarios: Machine vision calibration (security, film and television, medical, camera, drone camera, photography studio, scientific research instruments, and other equipment) Substrate: The substrate for the QR code calibration

Checkerboard Calibration Board The Checkerboard Calibration Board is one of the most widely used tools for camera and vision system calibration. Its high-contrast black and white square pattern allows precise corner detection, enabling accurate intrinsic and extrinsic parameter estimation. This ensures effective correction of lens distortion and reliable alignment of multi-camera or camera-to-robot systems. Manufactured with strict tolerances on durable materials such as

Irregular-Shaped Calibration Target The alien calibration board (asymmetric circular grid calibration board) is a high-precision visual calibration tool that combines the advantages of both checkerboard and ordinary circular grid calibration boards. It is one of the three mainstream calibration boards supported by OpenCV. Product Features: Non-planar visual system calibration, multi-view camera calibration, and calibration for irregular shapes such as circles, polygons, and

Large Scale 3D Calibration Board The large-sized 3D calibration board is a core calibration tool in fields such as machine vision, 3D reconstruction, and autonomous driving, which can achieve precise calibration of spatial coordinate systems and ensure measurement and imaging accuracy. 1. Core Features:Supporting various substrates such as glass, ceramics, and metals, the highest accuracy can reach ± 0.001mm, and some large-sized specifications can reach 800 × 960mm or even

Black Background White Dot Calibration Board / Photolithography White Film The photolithography white film dot array calibration plate is made using semiconductor level photolithography exposure and development technology, with high stability optical grade PET/PC white film as the core substrate. The surface is formed with high-precision white dot array and directional positioning marks by photolithography, which solves the problem of traditional glass calibration plates

Film Ruler Film Ruler is essentially a high-precision optical reference tool,commonly used for dimensional inspection,alignment calibration and accuracy verification.In simple terms,it can be understood as a"transparent ruler with precise scales",but its precision and manufacturing process are far superior to ordinary rulers.
