1. A computer implemented method for point-to-point measurement of image data, the method comprising: receiving an indication of a pair measurement points within an input image frame; determining a 3D spatial coordinate for each of a plurality of points along a measurement line defined by the pair of measurement points; filtering the 3D spatial coordinates associated with the measurement line to account for outliers; mapping the pair of measurement points to a pair of predicted points based on a function of the filtered 3D spatial coordinates; determining a distance between the pair of predicted points; and storing the distance to a memory in association with the pair of measurement points.
