Shape detection method, shape detection system, and program

A shape detection system for detecting a shape of an object, the system comprising:

• a three-dimensional point group data acquisition unit that acquires three-dimensional point group data from the object by a sensor;
• a three-dimensional point group data display unit that displays the three-dimensional point group data in a display area of a terminal;
• a two-dimensional image data acquisition unit that acquires the display area, in which the three-dimensional point group data is displayed, as two-dimensional image data;
• and
• an image analysis unit that performs image analysis on the two-dimensional image data to determine whether size or length of feature points of a predetermined color generated by densely packing point groups within the two-dimensional image data is equal to or greater than a predetermined value, and that detects a predetermined shape of the object based on an image analysis result.

A non-transitory computer-readable medium having computer-executable codes stored thereon, which, when executed by a processor, make a computer execute a shape detection method for detecting a shape of an object, the shape detection method, comprising:

• acquiring data indicating three-dimensional point group data from the object by a sensor;
• displaying the three-dimensional point group data in a display area of a terminal;
• acquiring the display area, in which the three-dimensional point group data is displayed, as two-dimensional image data;
• and
• performing image analysis on the two-dimensional image data to determine whether size or length of feature points of a predetermined color generated by densely packing point groups within the two-dimensional image data is equal to or greater than a predetermined value, and detecting a predetermined shape of the object based on an image analysis result.
