Camera Calibrator

Estimate geometric parameters of a single camera

Description

The Camera Calibrator app allows you to estimate camera intrinsics, extrinsics, and lens distortion parameters. You can use these camera parameters for various computer vision applications. These applications include removing the effects of lens distortion from an image, measuring planar objects, or reconstructing 3-D scenes from multiple cameras.

Open the Camera Calibrator App

  • MATLAB® Toolstrip: On the Apps tab, under Image Processing and Computer Vision, click the app icon.

  • MATLAB command prompt: Enter cameraCalibrator.

Programmatic Use

expand all

cameraCalibrator opens the Camera Calibrator app, which enables you to compute parameters needed to remove the effects of lens distortion from an image.

cameraCalibrator(imageFolder,squareSize) invokes the camera calibration app and loads calibration images from the imageFolder. The squareSize input must be a scalar in millimeters that specifies the size of the checkerboard square in the calibration pattern.

cameraCalibrator(sessionFile) invokes the app and loads a saved camera calibration session. Set the sessionFile to the name of the saved session file. The name must include the path to the MAT file containing the saved session.

cameraCalibrator CLOSE closes all open apps.

Introduced in R2013b
