1. A scanning control method, comprising:
controlling a scanner to preliminarily scan a to-be-scanned object according to a predetermined path to obtain a scanned model of the to-be-scanned model;
determining a watertight model of the to-be-scanned object according to the scanned model;
determining second predetermined positions of the scanner corresponding to respective first predetermined positions of the to-be-scanned object according to the watertight model and the respective first predetermined positions, wherein each of the second predetermined positions is on a scanning plane perpendicular to a plane where a rotating carrier bearing the to-be-scanned object is located, and the scanning plane is a two-dimensional plane on which the scanner is able to move; and
controlling the scanner to scan, at part of the second predetermined positions, the to-be scanned object at the corresponding first predetermined positions until a three-dimensional model is obtained;
wherein determining the second predetermined positions according to the watertight model and the respective first predetermined positions comprises:
determining geometric centers of the watertight mode corresponding to the respective first predetermined positions; determining one or more scanning spherical surfaces of the to-be-scanned object according to the geometric centers and the respective first predetermined positions; and determining the second predetermined positions according to the one or more scanning spherical surfaces and the scanning plane of the scanner;
or,
determining boundary lines of multiple longitudinal sections corresponding to the watertight model and parallel to a height direction of the to-be-scanned object according to the scanning plane and the respective first predetermined positions; and determining the second predetermiend positions according to the boundary lines.
