Therefore, the definition should be made based on the contents throughout this specification.

1 is a block diagram showing the configuration of an auto tee-up device having a golf ball crack inspection function according to an embodiment of the present invention.

Referring to FIG. 1, an auto tee-up device 100 having a golf ball crack inspection function according to an embodiment of the present invention includes a supply unit 110, a lighting unit 120, a processor 130, a camera unit 140, and an auto tee-up unit. It includes a tee-up unit 150. Here, the component that performs the golf ball crack inspection function is mainly included in the auto tee-up device 100, but in some cases, it may be installed outside the auto tee-up device 100 as a separate inspection device.

In addition, the auto tee-up device 100 may be mainly implemented with a steel material or a reinforced plastic material, but the material is not limited thereto.

In this specification, it will be described on the premise that the component performing the golf ball crack inspection function is included in the auto tee-up device 100, and in particular, the component performing the golf ball crack inspection function is included in the auto tee-up device 100. If included, the inside of the auto tee-up device 100 may be designed and manufactured as a black matte darkroom in order to obtain a clear image for golf ball crack inspection.

That is, when the inside of the auto tee-up device 100 is painted in a matte black color, light is absorbed and the amount of reflection is minimized, and thus the camera unit 140 can acquire a clear image of the golf ball.

On the other hand, the supply unit 110 may sequentially supply the golf ball to the top of the golf tee. The sequential supply means that after supplying the golf ball to the upper part of the golf tee, when the golf ball no longer exists on the upper part of the golf tee, the golf ball is supplied to the upper part of the golf tee again. Therefore, the supply unit 110 waits without supplying the golf ball to the top of the golf tee when the golf ball is present on the top of the golf tee.

Accordingly, a golf ball detection sensor for detecting whether a golf ball is present on the golf tee may be provided inside the auto tee-up device 100 .

In addition, the lighting unit 120 may emit light by adjusting the brightness of the golf ball located above the golf tee. The lighting unit 120 adjusts the brightness of the lighting to obtain an optimal image of the golf ball, and the brightness control of the lighting is implemented by a dimming unit to be described later.

The lighting unit 120 may be implemented with various types of light sources such as LED, halogen, and infrared light, and may include a plurality of light source devices.

Meanwhile, the camera unit 140 may acquire an image by photographing the golf ball in a state in which the brightness is adjusted by the lighting unit 120 .

For example, when the brightness is controlled by the lighting unit 120 and no shadow is cast on the golf ball or no shadow is formed on the golf ball, the camera unit 140 may acquire an image by photographing the golf ball. have.

The camera unit 140 may be implemented as one or more cameras, or may be implemented to repeatedly take pictures at the same angle and position like a motion control camera. Also, it is natural that it may be implemented by simply capturing a still image with a single camera.

In addition, the camera unit 140 may capture an image of the golf ball using light of various wavelengths such as visible light and infrared light.

Meanwhile, the processor 130 may pre-process the image acquired through the camera unit 140 to detect an edge, and determine whether a crack is present in the edge-detected image.

Specifically, the processor 130 determines whether or not there is a crack based on an image captured through the camera unit 140, but determines whether or not there is a crack in the golf ball itself being photographed live through the camera unit 140. It's not about judging.

Accordingly, the processor 130 needs to perform image processing on an image captured through the camera unit 140, and can determine whether or not there are cracks in the image on which such image processing has been performed.

Then, after the presence or absence of a crack is determined by the processor 130, the auto tee-up unit 150 may lift the golf ball located on the golf tee by utilizing a ball screw. Specifically, the auto tee-up unit 150 may operate a ball screw by driving a motor, and accordingly, the golf tee on which the golf ball is located and the panel on which the golf tee is fixed may move upward.

Meanwhile, the above-described image processing may be performed by the processor 130. Specifically, the processor 130 pre-processes the obtained image to adjust the brightness and contrast of the image, performs gray scale conversion, and performs edge , it is possible to perform conversion to increase sharpness, and to determine the presence or absence of cracks in the image based on the detected edges.

First, as described above, the image acquisition process 210 is performed through the camera unit 140 in a state where the shadow or contrast is not displayed on the golf ball by adjusting the lighting brightness through the lighting unit 120 .

The acquired image may be a moving image or a still image. The processor 130 may perform a preprocessing process 220 of adjusting brightness and contrast of the acquired image. Specifically, the processor 130 may make the obtained image relatively invisible by adjusting the brightness and contrast for an area where there is a prominent light and dark area on the image or a relatively dark or bright area is displayed conspicuously. have.

Further, the processor 130 may perform gray scale conversion on the obtained image to remove color differences, remove unnecessary light and dark areas, and clearly distinguish the boundary between the surrounding background and the golf ball.

In addition, the processor 130 may extract an edge, ie, an outline, by executing an edge detection algorithm 230 in the preprocessed image.

Then, the processor 130 performs conversion 240 to increase the sharpness of the extracted contour line, and finally extracts the contour line with high sharpness and accuracy to complete edge detection.

In addition, the processor 130 determines (250) whether or not there is a crack with respect to the detected edge.

Here, the dimming unit 160 may adjust the brightness of the lighting unit 120 . Specifically, the dimming control modulates the frequency width and the pulse width to adjust the amount of light emission, and unlike the analog method, it is possible to accurately control the amount of light emission.

For example, controlling the brightness of a light through pulse width modulation such as PWM control.

Then, the processor 130 controls the brightness of the lighting unit 120 by performing dimming control through the dimming unit 160, and while adjusting the brightness in this way, the golf ball image is captured through the camera unit 140. It is possible to remove foreign substances appearing on the surface of the
