Methods for detecting and measuring cracks in the lining of a container are also in the scope of the subject matter disclosed. Such methods include steps of fitting a polygonal mesh through a cloud of data points using a controller, the polygonal mesh having a resolution specified by a user and the cloud of data points being collected by a scanning device connected to the controller by measuring distances from the scanning device to a plurality of points on the surface of the lining material of the container; and fitting a minimum surface through the cloud of data points using the controller, wherein the crack is detected by a portion of the polygonal mesh containing a group of polygons that extends past the minimum surface beyond a threshold distance and the crack is measured by calculating a plurality of dimensions of the group of polygons.
