Hi Eric, Are you talking about the Camera Calibrator app in the Computer Vision System toolbox? If so, then unfortunately it only works with checkerboard images. However, under the hood the app calls the estimateCameraParameters function, and that you can use with any calibration pattern.. Camera calibration - checkerboard . cameraMarking steps: 1. Make a checkerboard (the size of each grid can be measured), it is best to print it out and paste it on a flat surface (if it doesn't work, use the black and white checkerboard method I just demonstrated) 2. According to the checkerboard , collect 10-20 pictures and extract the corner points. The calibration estimates the intrinsic parameters of a camera. For example, compute the motion of the camera, or compute a regulation of the point. Let's see how we calibrate in Matlab. We are going to use what is called the calibration toolbox. Download it or create your own. Mount your pattern on a flat, rigid surface. Take images of your checkerboard target in various orientations and distances. Download photos to compute and pick the above images that are in focus. Automatically detect the target and compute the parameters using provided examples.

I have a picture with a 4x4 object of known siye inside. I do not know the cameraParams. Is it possible to estimate them using 4 points sampled from the image (imagepoints) and 4 points in world coordinates from the object (world points). I do not have a checkerboard. Calibration is only as accurate as the calibration target used. Use laser printed targets only to validate and test. Proper mounting of calibration target and camera. In order to minimize distortion and bow in larger targets, mount them either vertically, or laying flat on a rigid support. Consider moving the camera in these cases instead..
