In the step of automatically adjusting the size of the drawing so that the drawing corresponds to the construction space using an image (S250), the size of the drawing projected in proportion to the ratio of the drawing area and the construction space area in the image of the construction space on which the drawing is projected is determined. Can be adjusted. As an example, in the image obtained in step S240, the size of the drawing to be projected later is increased by increasing the size of the drawing projected to the construction space by the ratio of the enlarged drawing image to the corner of the construction space image. It can be adjusted to fit the size of the project. In addition, as another embodiment, by calculating the ratio of the area of the construction space image to the drawing image on the image obtained in step S240, the size of the drawing projected to the construction space is increased by the calculated ratio, so that the drawing to be projected later is in the construction space.

First, the drawing size adjustment method (S250a) according to an embodiment of the present invention includes the step of detecting an edge of a drawing image on a photographed image (S251), as shown in FIG. 3, and the edge of the detected drawing image is Enlarging the drawing image to correspond to the corner of the image of (S253) and increasing the size of the drawing by the enlarged ratio (S255).

In the step of detecting the edge 411 of the drawing image on the captured image 400 (S251), the drawing image edge 411 is detected in the drawing image 410 within the area of the space-time image 430. As an embodiment, the edge 411 of the drawing image may be detected using a color value for each coordinate of the captured image 400. As an embodiment, detecting color value information for each coordinate from image data of the photographed image 400, and detecting coordinates of the upper, lower, left and right ends of an area corresponding to the RGB value of a preset laser irradiation color Thus, the coordinates of the corners of the drawing image can be detected. In addition, as another embodiment, from the color value information for each coordinate obtained from the photographed image 400, a coordinate value at a boundary where an RGB value is different may be detected as the drawing image edge 411. In this case, even when the RGB value of the irradiation color of the laser irradiation unit is not set, there is an advantage of being able to detect the edge 411 of the drawing image.

As an embodiment, the step (S253) of enlarging the drawing image 410 so that the edge 411 of the detected drawing image corresponds to the edge 430 of the image in the construction space (S253) is the drawing image edge detected in the step S251 ( It may include matching the coordinate values of the upper, lower, left and right ends corresponding to 411) to the coordinate values of the upper, lower, left and right corresponding to the space-time image corner 431, respectively.

In step S252 of detecting an area corresponding to the drawing image 610 on the captured image 600 (S252), the area of the drawing image 610 within the area of the space-time image 630 is detected. As an example, the area of the drawing image 610 may be detected using color values for each coordinate of the captured image 600. As an embodiment, detecting color value information for each coordinate from image data of the captured image 600, and detecting the coordinates of the upper, lower, left and right ends of an area corresponding to the RGB value of a preset laser irradiation color Accordingly, the area of the drawing image 610 may be detected. In addition, as another embodiment, the area of the drawing image 610 may be detected from a coordinate value at a boundary where an RGB value varies from color value information for each coordinate obtained from the captured image 600. In this case, there is an advantage in that the area of the drawing image 610 can be detected even when the RGB value of the irradiation color of the laser irradiation unit is not set.

As an embodiment, calculating the ratio of the area of the space-time image 630 to the area of the detected drawing image 610 (S254) includes the upper, lower, and left edges of the area of the drawing image 610 detected in step S252. And the coordinate values of the right end and the coordinate values of the upper, lower, left and right ends of the space-time image 630 area. As an example, the area of the drawing image 610 area and the coordinate values of the top, bottom, left and right ends of the space image 630 area according to the coordinate values of the top, bottom, left and right ends of the drawing image 610 area. By calculating the area of the space-time image 630 according to each, the ratio can be obtained.

In another embodiment, the ratio of the area of the construction space image 630 to the area of the detected drawing image 610 is the size of the area corresponding to the drawing image 610 as shown in FIG. It can be calculated by area distribution. That is, in the case of FIG. 6, the ratio of the area of the space-time image 630 to the area of the detected drawing image 610 may be calculated as 1:9.

In the step of expanding the size of the drawing by the calculated ratio (S255), the size of the drawing projected on the construction space may be enlarged by the ratio of the area of the construction space image 630 to the area of the drawing image 610 calculated in step S254. have. That is, in the case of FIG. 6, since the ratio of the area of the construction space image 630 to the area of the drawing image 610 is 1:9, the size of the drawing projected on the construction space may be enlarged and adjusted by 9 times. In this way, by adjusting the size of the drawing projected on the construction space according to the ratio of the drawing image 610 and the construction space image 630 on the photographed image 600, the drawings projected on the construction space automatically correspond to the construction space. Can be adjusted.

As shown in FIG. 7, the size-adjusted drawing 720 may be projected to match the size of the construction space 710. In this case, at least one of color, brightness, shape, line thickness, and line type may be differently output from the components 721, 722, and 723 of the drawing. As an example, as shown in FIG. 7, different line thicknesses of the first configuration 721, the second configuration 722, and the third configuration 723 may be output for each configuration of the drawing. In this case, it is possible to intuitively indicate that the work order is the order of the first configuration 721, the second configuration 722, and the third configuration 723 by outputting the line thickness of the components to become thinner according to the work order of the drawing. . Accordingly, there is an effect of preventing an operator's mistake and reducing working time. In addition, when the additional information for each configuration of the drawing is input in step S220 of FIG. 2, the additional information 725 input for each configuration of the drawing may be combined with the drawing and projected onto the construction space. For example, as the additional information, a work order for each configuration of a drawing, a name or a serial number of a work target configuration, a material, etc. may be entered. Accordingly, even if the operator is a beginner, there is an advantage of being able to work easily.
