First calibration example - Corner extraction, calibration,
additional tools
This section takes you through a complete calibration example based on
a total of 20 (and 25) images of a planar checkerboard.
This example lets you learn how to use all the features of the toolbox:
loading calibration images, extracting image corners, running the main
calibration engine, displaying the results, controlling accuracies,
adding and suppressing images, undistorting images, exporting
calibration data to different formats... This example is highly
recommended for someone who is just starting using the toolbox.
� Download the calibration images all at once calib_example.zip
(4461Kb zipped) or one by one, and store the 20 images into a
seperate folder named calib_example.
� From within matlab, go to the example folder calib_example
containing the images.
� Reading the images:
Click on the Image names button in the Camera calibration tool
window. Enter the basename of the calibration images (Image)(输入图
像名字，除了序号外的名字) and the image format (tif)(格式).
All the images (the 20 of them) are then loaded in memory (through
the command Read images that is automatically executed) in the
variables I_1, I_2 ,..., I_20. The number of images is stored in
the variable n_ima (=20 here).
The matlab window should look like this:
