Electronic device and method for measuring point cloud of object

An electronic device, comprising:

• a storage device;
• at least one processor;
• and
• one or more modules that are stored in the storage device and executed by the at least one processor, the one or more modules comprising:
• a point-cloud obtaining module that obtains an original point-cloud of an object from the storage device;
• a point filtering module that filters discrete points from the original point-cloud, determines a first sub-point-cloud and a second sub-point-cloud from the filtered point-cloud, and creates an updated point-cloud of the object based on the first sub-point-cloud and the second sub-point-cloud;
• a reference figure obtaining module that determines points to be fitted from the updated point-cloud, and fits a figure according to the determined points;
• the reference figure obtaining module further determines a reference figure according to the fitted figure;
• a point selecting module that determines a first point having a maximum curvature from the first sub-point-cloud, and determines a second point having the maximum curvature from the second-point-cloud;
• a calculating module that calculates a gap width and a gap height of the updated point-cloud of the object according to the first determined point, the second determined point, and the reference figure;
• and
• a measurement result output module that displays the gap width and the gap height on a display device of the electronic device.

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

• obtaining an original point-cloud of the object from a storage device of the electronic device;
• filtering discrete points from the original point-cloud, determining a first sub-point-cloud and a second sub-point-cloud from the filtered point-cloud, and creating an updated point-cloud of the object based on the first sub-point-cloud and the second sub-point-cloud;
• determining points to be fitted from the updated point-cloud, and fitting a figure according to the determined points;
• determining a reference figure according to the fitted figure;
• determining a first point having a maximum curvature from the first sub-point-cloud, and determining a second point having the maximum curvature from the second-point-cloud;
• calculating a gap width and a gap height of the updated point-cloud of the object according to the first determined point, the second determined point, and the reference figure;
• and
• displaying the gap width and the gap height on a display device of the electronic device.
