Abstract

A nail shape extraction system and method, a storage medium, a nail tip, and a manufacturing system for the nail tip are provided. The nail shape extraction system uses a cyclic processing device for point cloud extraction and/or flattening. The cyclic processing device includes a point cloud acquisition module configured to convert point cloud data into a point cloud list and a point cloud processing module configured to perform a cyclic action on points in the point cloud list under a determination condition to obtain a new point cloud list. The point cloud processing module includes a pushing unit, a selection unit, an action unit, an elimination unit, and a circulation unit for promoting the selection unit, the action unit, and the elimination unit to act cyclically.

Dependent claims

A nail shape extraction system based on point clouds, comprising a cyclic processing device for processing point clouds, wherein the cyclic processing device comprises:

a point cloud acquisition module configured to acquire point cloud data, convert the acquired point cloud data into a point cloud list, and output the point cloud list;
and
a point cloud processing module connected to the point cloud acquisition module, and configured to perform a cyclic action on points in the point cloud list output by the point cloud acquisition module to obtain a new point cloud list;
the point cloud processing module comprises:
a pushing unit connected to the point cloud acquisition module, and configured to acquire the point cloud list output by the point cloud acquisition module and push all the points in the point cloud list into an empty to-be-acted point list;
a selection unit connected to the pushing unit, and configured to select one point from the to-be-acted point list as a current to-be-acted point and search for all neighboring points of the current to-be-acted point under a set condition;
an action unit connected to the selection unit, and configured to select neighboring points meeting an action condition from the neighboring points, classify the neighboring points to select a growing action or a flattening action and then push the neighboring points meeting the action condition into the point cloud list and the to-be-acted point list;
an elimination unit connected to the action unit, and configured to mark the current to-be-acted point as an acted point and eliminate the acted point from the to-be-acted point list;
and
a circulation unit connected to the selection unit, the action unit and the elimination unit, and configured to promote the selection unit, the action unit and the elimination unit to act cyclically until the to-be-acted point list is emptied to obtain the new point cloud list.

7 more elements

A nail shape extraction system based on point clouds, comprising a step of cyclic processing of point clouds, wherein the step of cyclic processing comprises:

S1:
acquiring point cloud data, converting the acquired point cloud data into a point cloud list and outputting the point cloud list, by a point cloud acquisition module;
and
S2:
establishing an empty to-be-acted point list, performing, by a point cloud processing module, a cyclic action on points in the point cloud list output by the point cloud acquisition module, and obtaining a new point cloud list;
S2 comprises:
S21:
acquiring the point cloud list output by the point cloud acquisition module and pushing all the points in the point cloud list into the empty to-be-acted point list, by a pushing unit, such that the point cloud list is emptied;
S22:
selecting one point from the to-be-acted point list as a current to-be-acted point and searching for all neighboring points of the current to-be-acted point under a set condition, by a selection unit;
S23:
selecting neighboring points meeting an action condition from the neighboring points, classifying the neighboring points to select a growing action or a flattening action and then pushing non-acted neighboring points meeting the action condition into the point cloud list and the to-be-acted point list, by an action unit;
S24:
marking the current to-be-acted point as an acted point and eliminating the acted point from the to-be-acted point list, by an elimination unit;
and
S25:
selecting another point from the to-be-acted point list as a new current to-be-acted point, and repeating S22-S24 by a circulation unit until the to-be-acted point list is emptied to obtain the new point cloud list.
