| titleOfInvention | Point-to-point distance measurement in 3D camera images |
| abstract | Systems and methods are used to determine point-to-point distances from 3D image data. In some embodiments, the two measurement points, eg, specified by the user, represent endpoints on the object of interest within the image frame. Assuming that all points located between these endpoints also belong to the object of interest, additional 3D data associated with points located along the measurement line defined by the measurement points can be employed to provide robust distance measurements. In some embodiments, a global least squares fit is performed, eg, by Robust Principal Component Analysis (RPCA), to identify linear structures within the set of 3D coordinates on the survey lines. In some exemplary embodiments, a minimum covariance determinant (MCD) estimator of the covariance matrix of the data is computed for highly robust estimates of multivariate location and multivariate dispersion. |
