Using Triangle-region Method to Measure Stockpile's Volume

In the volume calculation of stockpile by using computer-aided measuring technique, a new volume calculation method is introduced. It includes six steps which are purifying and standardizing raw data, getting partial derivative of data points, building triangle grid, surface fitting of triangle region, cal-culation triangle region volume, calculation volume of stockpile. Based on this algorithm, an application system is developed, and it is testified valid and practical by analyzing instances.
