Abstract

Techniques are described for calibrating an AR device having a camera, an antenna, an EDM device, and a display. First and second distances to first and second points are captured using the EDM device. First and second camera images containing the first and second points are captured using the camera. First and second 2D screen coordinates for the first and second points on the display are determined using the first and second camera images. First and second 3D surface points for the first and second points are computed based on the first and second 2D screen coordinates and the first and second distances. A position of the EDM device is computed using a 3D vector formed between the first and second 3D surface points. A camera-to-antenna offset is computed based on the position of the EDM device and a known antenna-to-EDM offset.
