Abstract
A three-dimensional scan system and an operating method thereof are provided. Embodiments of the present disclosure provide a method and a three-dimensional scan system for analyzing property information of an object from at least one image obtained by imaging an object to which light is projected, and automatically changing the color of a light source projecting light to the object based on the analyzed property information.
Claims15
A three-dimensional scan system comprising:
- a light projector configured to project red (R) light, green (G) light, or blue (B) light to an object;
- an image capturer configured to obtain at least one image of the object by imaging the object to which the R light, the G light, or the B light is projected by the light projector;
- a data analyzer configured to obtain a color histogram representing a cumulative distribution ratio of a number of image pixels having each of R color, G color, or B color by analyzing color information of the at least one image;
- and
- a controller configured to:
- identify a color having a greatest cumulative distribution ratio of image pixels among R, G, or B, by analyzing the color histogram, and
- control the light projector to change a color of a light, from among the R light, the G light, or the B light, corresponding to the identified color having the greatest cumulative distribution ratio of the image pixels.
An operating method of a three-dimensional scan system, the operating method comprising:
- projecting, by using a light projector of the three-dimensional scan system, red (R) light, green (G) light, or blue (B) light to an object;
- obtaining at least one image of the object by imaging the object to which the R light, the G light, or the B light is projected by the light projector;
- analyzing property information of the object from the obtained at least one image;
- and
- changing a color of the light source projecting light to the object based on the analyzed property information,
- wherein the analyzing of the property information comprises:
- obtaining a color histogram representing a cumulative distribution ratio of a number of image pixels having each of R color, G color, or B color by analyzing color information of the at least one image, and
- identifying a color having a greatest cumulative distribution ratio of image pixels among the R, G, or B, by analyzing the color histogram, and
- wherein the changing of the color of the light source comprises changing a color of the light, from among the R light, the G light, or the B light, corresponding to the identified color having the greatest cumulative distribution ratio of the image pixels.
A non-transitory computer-readable recording medium having a program recorded thereon, which includes at least one instruction for performing an operating method of a three-dimensional scan system by using a computer, the operating method comprising:
- projecting, by using a light projector of the three-dimensional scan system, red (R) light, green (G) light, or blue (B) light to an object;
- obtaining at least one image of the object by imaging the object to which the R light, the G light, or the B light is projected by the light projector;
- analyzing property information of the object from the obtained at least one image;
- and
- changing a color of the light source projecting light to the object based on the analyzed property information,
- wherein the analyzing of the property information comprises:
- obtaining a color histogram representing a cumulative distribution ratio of a number of image pixels having each of R color, G color, or B color by analyzing color information of the at least one image, and
- identifying a color having a greatest cumulative distribution ratio of image pixels among the R, G, or B, by analyzing the color histogram, and
- wherein the changing of the color of the light source comprises changing a color of the light, from among the R light, the G light, or the B light, corresponding to the identified color having the greatest cumulative distribution ratio of the image pixels.
