Abstract

A point cloud measuring system includes client computers (1), an application server (2) and a database (3). The client computers communicate with the application server, and enable uses to perform needed operations. The database stores data generated and used by the system. The application server includes: a point cloud fitting module (200) for fitting selected point clouds into an object; a coordinate system creating module (201) for creating a coordinate system; a measurement object creating module (202) for creating a measurement object according to particular objects selected by the user; a measuring module (203) for measuring the measurement object in the coordinate system; and a measurement data outputting module (204) for outputting measurement data on the measurement object, and determining whether the measurement data meet with design requirements by comparing the measurement data with corresponding design dimensions of the measurement object. A related method is also disclosed.

Dependent claims

A point cloud measuring system for automatically and accurately measuring point clouds, the system comprising a plurality of client computers and an application server, wherein:

the client computers are for providing user interfaces enabling users to communicate with the application server;
and to perform needed measuring operations for point clouds;
and
the application server performs the function of measuring point clouds, the application server comprising:
a library, comprising:
a point cloud fitting module for fitting point clouds selected by a user through a user interface of any one of the client computers into an object;
a measurement object creating module for creating a measurement object according to objects selected by the user;
a measuring module for measuring the measurement object and obtaining measurement data on the measurement object;
and
a measurement data outputting module for outputting the measurement data, and determining whether the measurement data meet with design requirements by comparing the measurement data with design dimensions of the measurement object.
a measurement step storing module for storing measurement steps of measuring the measurement object in a database, in order to make the steps of measuring the measurement object available for measuring a same measurement object in future;
and
an error detecting module for determining in real time whether any error occurs when utilizing any of the modules of the library, and advising the user of an error that occurs.
