A calibration system is described that includes a calibration target having one or more calibration objects, a head mounted display (HMD), and a rendering engine configured to render, based on an estimated pose of the HMD, respective virtual calibration objects in a viewing area of the HMD at respective locations corresponding to the one or more calibration objects visible in the viewing area, wherein the HMD is configured to output the virtual calibration targets. The calibration system further includes an image capture system configured to capture image data comprising images of the viewing area of the HMD, and a calibration engine configured to compute, from the image data, difference data comprising respective distances between the one or more calibration objects and the respective, corresponding virtual calibration objects.
