Abstract

When studying 3D objects, one of the important properties of practical significance is to calculate volume. Calculating of the volume can be used for a lot of applications in many brands such as: in designing drainage systems for roads; in dredging the waterway traffic; in digging and filling engineering constructions; in mining in the design, inventory for management and exploitation of minerals; in calculating the volume of civil engineering,… Recently there have been some reseaches which gave different solutions to solve this problem by TIN model. However, by studying the methods mentioned above, these solutions are complex in calculating and are not optimized, the data collection process must be followed by some definite conditions. This paper gives a method for calculating the volume in the general case for 3D objects with any shape. According to this method, the caculated process becomes simple, the organization of field work is flexible, multiple ways and not complicated.
