Abstract: The present disclosure provides a method for constructing a three-dimensional solid model with a geometric error and a computer-readable storage medium. The method includes: S10: obtaining an ideal geometric solid model of a component; S20: constructing a geometric error model for a surface of the component by use of geometric error data of the surface of the component; and S30: replacing a corresponding surface in the ideal geometric solid model with the geometric error model to obtain a three-dimensional solid model with a geometric error. The method for constructing a three-dimensional solid model provided by examples of the present disclosure integrates a geometric error of a component with a CAD model, so as to obtain a three-dimensional solid model with a geometric error, which describes a regular appearance characteristic of a real surface of the component macroscopically, and also reflects an irregular geometric error shape characteristic of the surface of the component microscopically.

Abstract: Systems and methods for the collection, verification, and maintenance of point of interest information are provided. One example system includes a plurality of mobile collection devices respectively operated by a plurality of human collectors. Each of the mobile collection devices uploads to one or more intermediate servers information describing one or more attributes of a plurality of points of interest. The system includes a mobile verification device that receives, from the one or more intermediate servers, information uploaded by a first mobile collection device and provides an indication of an accuracy associated with the information received from the first mobile collection device. The system includes the one or more intermediate servers. The system includes one or more production servers. The information uploaded by the first mobile collection device is transcribed from the one or more intermediate servers to the one or more production servers.
