Generate PDF camera calibration patterns for OpenCV, Matlab Computer Vision Toolbox, and a large number of photogrammetry software packages. We propose directly inferring camera calibration parameters from a single image using a deep convolutional neural network. For a 50mm lens, that would be at least 2.5 meters. In this section, the camera calibration procedure is broken down into steps and explained. Choose your camera in the list, and you'll see the view from the camera in the area to the left. 500 500 500 500 500 500 500 500 500 500 500 277.8 277.8 277.8 777.8 472.2 472.2 777.8 /Name/F6 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 963 379.6 963 638.9 963 638.9 963 963 For better understanding, we have also included an example of Pixhawk (IMU) and ZED camera (stereo camera) calibration procedure.
