{"product_id":"opencv-calibration-board","title":"OpenCV calibration board","description":"\u003cp class=\"MsoNormal\"\u003e\u003cspan lang=\"EN-US\"\u003eThe 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 glass, metal, or composites, the board provides excellent stability and repeatability. Compatible with popular vision libraries like OpenCV and Halcon, it is commonly applied in robotics, 3D reconstruction, industrial automation, and machine vision applications requiring high calibration accuracy.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan lang=\"EN-US\"\u003eProduct Features: Clear pattern corners, high precision, high contrast\/non-reflective, High precision (with a maximum accuracy of 1um),supports diversified customization\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan lang=\"EN-US\"\u003eApplicable scenarios: Machine vision calibration (security, film and television, medical, cameras, drone cameras, photography studios, scientific research instruments, and other equipment)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan lang=\"EN-US\"\u003eBase material: The base material of the checkerboard calibration board is optional, and different base materials (such as glass, ceramic, film, aluminum plate, etc.) can be customized according to different usage scenarios, environments, and accuracy requirements.\u003c\/span\u003e\u003c\/p\u003e","brand":"我的商店","offers":[{"title":"Default Title","offer_id":45257206988823,"sku":null,"price":1000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/4678\/3511\/files\/1.png?v=1782981233","url":"https:\/\/dfstore.net\/products\/opencv-calibration-board","provider":"我的商店","version":"1.0","type":"link"}
