Tangram Vision + OpenCV
Exclusive OpenCV Offer
Buy One, Get One Free
Purchase one MetriCal Basic Credit Bundle (15 credits) and get a second bundle free; that's 30 credits total. Use your credits to perform sensor calibrations with MetriCal's professional calibration platform. Your purchase also helps support OpenCV's mission to advance computer vision technology.
Offer available to first-time MetriCal users only. One-time offer, redeemable once per customer.
A Natural Pair
OpenCV is the backbone of computer vision worldwide, powering everything from academic research to production robotics. Tangram Vision brings production-grade calibration technology that goes far beyond what's available through traditional tools.
Through this partnership, MetriCal is now available to the OpenCV ecosystem with an exclusive offer. We're making professional multi-sensor calibration accessible to every computer vision practitioner.
What is MetriCal?
Multi-Sensor Calibration
Calibrate cameras, LiDARs, IMUs, and navigation systems simultaneously in one workflow.
Production-Grade Results
Sub-pixel reprojection error and sub-millimeter precision across all modalities.
Sensor Agnostic
Works with Intel RealSense, FLIR, Velodyne, Ouster, Bosch, VectorNav, and more.
Fast and Repeatable
Results in seconds, not hours. Consistent quality across your entire fleet.
Built for OpenCV Workflows
MetriCal is a professional calibration platform that goes far beyond cv::calibrateCamera(). Use the camera models you already know, migrate from tools you already use, and get results you can use immediately.
Native Support
OpenCV Camera Models
MetriCal natively supports opencv-radtan and opencv-fisheye intrinsics models. Use the same distortion parameters your OpenCV code already expects.

Migration
Kalibr to MetriCal
Already using Kalibr? MetriCal maps directly from Kalibr's pinhole-radtan and pinhole-equi models. Migrate your calibration workflow with zero friction.
Pipeline Ready
Drop-In Results
MetriCal outputs calibration parameters your OpenCV pipeline already consumes, including per-pixel lookup tables compatible with OpenCV's remap function for image rectification.
