    Skip to content. This will open up the calibration window which will highlight the checkerboard, you will not see any images in the calibration window until a checkerboard is present: Dual Checkerboards New in D Starting in Diamondback, you will be able to use multiple size checkerboards to calibrate a camera. If you wish to calibrate your cameras, this step should be done after setting up ROS and running voxl-configure-cameras. You can print an acircles card from here. We also use a 6x7 checkerboard with 50mm spacing. New in noetic For fisheye type cameras this package uses equidistant distortion model with the name equidistantaccording to documentation. If you are getting an error that a package can't be found.

    This repository contains the custom ROS package my_camera_calibration. It is used to calibrate a usb_camera or other camera specified by the user using the ROS.If you are not using a webcam, then you will need to modify the camera.

    For fisheye type cameras this package uses equidistant distortion model but names it as fisheye.

    Calibration Results After the calibration is complete you will see the calibration results in the terminal and the calibrated image in the calibration window: The sidebar will show the measured accuracy and dimensions of the checkerboard square, in the above case the checkerboard square was mm with an accuracy of 0.

    This tutorial uses a 8x6 checkerboard with mm squares a well lit 5m x 5m area clear of obstructions and check board patterns a stereo camera publishing left and right images over ROS if you want to use two independent cameras as a stereo camera, you must make sure the images have identical time stamps NOTE : Checkerboard size refers to the number of internal corner, as described in the OpenCV documentation i.
