Abstract: A method of optimizing measurement paths analyzes one or more measurement points for each of the measurement elements of a product and generates relation arrays, each of the relation arrays storing the name and the one or more measurement points of one measurement element. The method selects a measurement point which is the nearest to the origin of an coordinate system of the product, computes distances between the measurement points from the selected measurement point using the relation arrays, and orders the measurement points according to the computed distances to generate a first ordered array. The method generates an optimal measurement path according to the first ordered array.

Abstract: A method of optimizing measurement paths computes a minimum bounding box for the measurement elements on a product, and computes a capturing range of a lens of a measurement machine. The method divides the minimum bounding box into M*N partitions according to the capturing range, and assigns a number to each of the M*N partitions. The method puts the number of a partition which exclusively encloses a measurement element into a first array, and puts a number set that includes the numbers of the partitions which all enclose a measurement element into a second array, and lists the numbers of the partitions in order according to the first array and the second array to generate a measurement path.
