Electronic device and method for measuring point cloud of an object

An electronic device comprising:

• a processor;
• and
• a storage device that stores one or more programs and, when executed by the at least one processor, cause the at least one processor to:
• obtain a point cloud of an object from a storage device of the electronic device;
• construct a triangular mesh surface based on the point cloud;
• determine triangles of the triangular mesh surface;
• store the triangles in a queue;
• determine a reference plane according to the triangles stored in the queue;
• establish a three dimensional (3D) object coordinate system according to the reference plane;
• calculate 3D object coordinates of points in the point cloud in the 3D object coordinate system;
• determine measurement elements of a profile of the point cloud;
• determine points in the point cloud corresponding to each of the measurement elements;
• fit each of the measurement elements in the 3D object coordinate system according to the 3D object coordinates of the determined points corresponding to each of the measurement elements;
• and
• calculate a distance and an angle of two fit measurement elements.

A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a method for measuring point cloud, wherein the method comprises:

• obtaining the point cloud of the object from a storage device of the electronic device;
• constructing a triangular mesh surface based on the point cloud;
• determining triangles of the triangular mesh surface and storing the triangles in a queue;
• determining a reference plane according to the triangles stored in the queue;
• establishing a three dimensional (3D) object coordinate system according to the reference plane, and calculating 3D object coordinates of points in the point cloud in the 3D object coordinate system;
• determining measurement elements of a profile of the point cloud;
• determining points in the point cloud corresponding to each of the measurement elements;
• fitting each of the measurement elements in the 3D object coordinate system according to the 3D object coordinates of the determined points corresponding to each of the measurement elements;
• and
• calculating a distance and an angle of two fit measurement elements.
