摘要： A method for checking a boundary line graph using a computing device. The computing device adds a segment line between two adjacent endpoints of the boundary line graph, if the two adjacent endpoints are not connected using the segment line. The computing device removes the segment lines of the endpoints corresponding to intersection points, if the number of the intersection points is not equal to the number of the endpoints. The computing device changes label characters of the endpoints to be arranged in a predetermined order, if an order of the label characters of the endpoints is not a predetermined order according to the boundary line vector.

摘要： A method outputs measurement data automatically using an electronic device. The method obtains measurement data of feature elements from a two dimensional (2D) image of a measured object, determines a type of measurement applied to each feature element, obtains feature elements from planes of a three dimensional (3D) image of the measured object, and maps each of the obtained feature elements in the 3D image to the 2D image. The method further obtains sequential marked numbers from the 2D image, determines a feature element which is nearest to any marked number from the mapped feature elements, determines an output axis for each of the determined feature elements, and outputs measured results and measurement codes of the determined feature elements by reference to the measurement data, the type of measurement and the output axis of each determined feature element.
