A method for determining the volume of a three-dimensional object

The invention discloses a method for calculating the volume of a three-dimensional object, which comprises the following steps: S1, recovering the three-dimensional space coordinates of the surface ofa target curved object from a two-dimensional image; S2, dividing the target object into planar pieces; S3, calculating the area of the planar patch; S4, integrating the plane slice to obtain the volume of the target object. The invention has strong robustness for calculating the volume of the three-dimensional target object, and is suitable for the cases of known discrete point coordinates of the surface of the target object, irregular target object and the like. 本发明公开了种三维物体体积的计算方法，包括S1由二维图像恢复目标曲物体表面的三维空间坐标；S2分割目标物体成平面片；S3计算平面片的面积；S4对平面片进行积分，得到目标物体体积，本发明对于三维目标物体体积的计算鲁棒性强，适用于已知目标物体表面的离散点坐标、目标物体不规则等情况。
