Referring to FIG. 1 , the auto tee-up apparatus 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 100 . It includes a tee-up unit 150 . Here, the component for performing 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 the present 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 dark room in order to obtain a clear image for inspecting a golf ball crack.

That is, when the inside of the auto tee-up device 100 is painted with black matte, light is absorbed and the amount of reflection is minimized, and accordingly, 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 is no longer present on the upper part of the golf tee, the golf ball is again supplied to the upper part of the golf tee. Accordingly, 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 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 light to obtain an optimal image of the golf ball, and the brightness control of the light 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, infrared, and the like, and may include a plurality of light source devices.

For example, when the brightness is adjusted by the lighting unit 120 and the golf ball is not in a state in which light is not cast or a shadow is not formed in the golf ball, the camera unit 140 may photograph the golf ball to obtain an image. have.

Such a camera unit 140 may be implemented as one or more cameras, or may be implemented to perform repeated shooting at the same angle and position as a motion control camera. In addition, it is natural that it may be implemented by simply photographing a still image with one camera.

In addition, the camera unit 140 may take 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 or not there is a crack in the image in which the edge detection is completed.

Specifically, the processor 130 determines whether there is a crack based on the image captured by the camera unit 140 , and 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 requires image processing for the image captured by the camera unit 140 , and may determine whether there is a crack in the image on which the image processing has been performed.

And, after the presence of cracks is determined by the processor 130, the auto tee-up unit 150 may raise the golf ball located on the golf tee by using the ball screw. Specifically, the auto tee-up unit 150 may drive the motor to operate the ball screw, and accordingly, the golf tee on which the golf ball is located and the panel on which the golf tee is fixed may be moved upwardly.

On the other hand, the above-described image processing may be performed by the processor 130 , and specifically, the processor 130 pre-processes the acquired image to adjust the brightness and contrast of the image, performs grayscale conversion, and performs edge in the pre-processed image. may be detected, a transformation to increase sharpness may be performed, and the presence or absence of a crack may be determined in the image based on the detected edge.

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

In addition, the processor 130 may perform gray scale conversion on the acquired image to remove a difference due to color, remove unnecessary light and dark areas, and clearly distinguish a boundary between a surrounding background and a golf ball.

In addition, the processor 130 may extract an edge, that is, a contour, by executing 230 an edge detection algorithm from the preprocessed image.

Then, the processor 130 performs the transformation 240 to increase the sharpness on the extracted outline, and finally extracts the outline with high sharpness and accuracy to complete edge detection.

In addition, the processor 130 determines (250) whether there is a crack with respect to the detected edge.
