Green information providing method using photo and terminal {GREEN INFORMATION PROVIDING METHOD USING PICTURE AND TERMINAL THEREOF}

The present invention relates to a method for providing green information using a photo and a terminal thereof, and more particularly, to generate green information by three-dimensional image of a green picture by image-based modeling, and to actually green picture taken by the green information and the golfer. The present invention relates to a green information providing method and a terminal using a photo for displaying green information from a golf ball to a hole cup by matching patterns extracted from each other.

The golf market is largely divided into the US and Europe, and in Asia, as the economy of China grows and the national income increases, the golf population is increasing. Has declined and entered recession, golf experts say.

On the other hand, Putting Green is an area where golf balls are inserted into the hole cups with an average of two strokes by rolling the golf balls onto the grass on the mat where the hole cups are formed.

In the case of putting in golf, it is necessary to accurately grasp the inclination of the lie or the green on the green and hit the golf ball in the appropriate strength and direction to put the golf ball into the hole cup.

Therefore, putting has been considered the most important factor in a golf game because the impact on the score is so large that golfers step back a few steps behind the ball to figure out the lie between the golf ball and the hole cup before putting on the green. Sit down or observe the slope of the green, almost level with eye level.

At this time, in order to determine the intermediate inclination between the golf ball and the hole cup, it may be observed from the left or right side, may also be observed from the back or the rear of the hole cup, and grasping the fine lie around the hole cup is also essential for accurate putting.

In addition, the professional golfer rounds the course with the caddy in advance, and the caddy frequently grasps the characteristics of each hole to make a yard book, and provides the golfer with help information during the actual game. In this case, it is difficult to receive this help information, and the ability to read the green slope makes the process of putting a golf ball into a hole cup on a putting green very difficult.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

It should be noted that the same elements among the drawings are denoted by the same reference numerals and symbols as much as possible even though they are shown in different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In addition, when a part is said to "include" a certain component, this means that it may further include other components, except to exclude other components unless otherwise stated.

1 is a flowchart of a method for providing green information according to an embodiment of the present invention, and FIG. 2 is an exemplary view of a green for explaining FIG. 1.

The green information providing method according to the present invention largely comprises an original DB acquisition process (S102-S112), a user's actual information acquisition process (S114-S116), a matching process (S118), and a display process (S220).

First, in the process of acquiring the original DB, one or more photo zones (4) are designated by setting a position where the whole of the putting green can be photographed around the putting green (1) while showing the shape and feature points of the putting green. (S102).

The green 1 is photographed using the camera in the designated photo zone 4 so that the green edge 6, the green surrounding bunker 5, and the like enter (S104).

At this time, in order to detect the image depth of the real object (green), which is information for acquiring a 3D image, parallel stereoscopic imaging and cross-visual stereoscopic imaging are performed or drawn using a single camera. 1) Shoot.

Or by using Terrestrial LiDAR (Terrestrial Light Detection And Ranging) surveying equipment, the laser beam is emitted to the surveying object (green), and the return time and phase difference are calculated to calculate the position information and image information of the object (green). Acquire combined three-dimensional spatial information.

The green picture is stored in a computer or the like, and an image program is executed to remove additional images such as hole positions, golf tools (for example, the flagpole of the hole cup), and other human shapes to generate a pure green image (S106).

Next, three-dimensional green information is acquired by post-processing image-based modeling such as simplifying the pure green image, rotating the simplified pure green image, and adjusting the height (S108).

That is, green information is generated by imaging in three dimensions by image-based modeling which reconstructs three dimensions in a manner of detecting the depth of the real object from a two-dimensional green photograph.

At this time, the depth of the three-dimensional object and the three-dimensional image according to the depth may be calculated from at least two images based on the parallel stereoscopic method or the cross-visual stereo method, and the image obtained from one camera may be processed separately. It can also be 3D imaging.

For example, in the parallel-vision stereo system, when two lens projection center lines are placed in parallel, an image of the same object point is placed on an epipolar line generated by the object point (a line formed by two lens centers and an image plane). In this case, the depth of the real object may be sensed by the distance between the lens center and the focal length and the distance between the projection objects in the image plane through the two lenses.

In the next 3D green information, feature points such as green edges and bunkers surrounding the green and a pattern of a specific area are extracted and stored together with the 3D green information (S110).

This feature point extraction utilizes face recognition and fingerprint recognition techniques to perform binarization and thinning, and finally to extract feature point data.

In addition, after converting the image of the three-dimensional green information into a binary image, the pattern is extracted from the feature region of the binary image.

In this case, the pattern may be extracted from the region of the extracted feature point in the image of the 3D green information.

After the three-dimensional green information is stored in the original DB built in the green information providing server (not shown) through these steps, the green information providing server 10 is connected to the green information providing terminal 10 to display the three-dimensional green information of a specific golf course. Download and save.

When the golf ball 2 is located on the green 1 when the golfer is rounded by the user's actual information acquisition process, the golfer moves to any one or more photo zones of the designated photo zone 4 to the green information providing terminal 10. The green 14 is photographed using the provided camera 14 so that the green edge 6, the golf ball 2, the hole cup 3, the bunker 5 around the green, etc. are represented (S112).

After removing additional images such as golf tools and other human shapes from the actual green picture, feature points such as the green edge 6 and the green surrounding bunker 5 and patterns of specific areas are extracted (S114).

In this case, the feature point may be extracted first, and then the pattern of the feature point region may be extracted.

The golf ball 2 and the hole cup 3 are identified in the actual green picture to generate the position information of the golf ball 2 and the hole cup 3 (S116).

In the next matching process, the pattern extracted from the 3D green information and the pattern extracted from the green picture taken by the golfer are compared and matched to each other, thereby matching the positions of the golf ball 2 and the hole cup 3. After extracting to a relative value, it is converted to an absolute position and displayed on an image of 3D green information (S118).

After displaying the entire image of the 3D green information in the display process, the 3D green information from the golf ball 2 to the hole cup 3 is displayed on the display unit 18 of the green information providing terminal 10. (S120).

In this case, the distance between the golf ball 2 and the hole cup 3 and the slope and the left and right inclination may be displayed on one side of the display unit 18, and three-dimensional green information is displayed from the golf ball 2 to the hole cup 3. Then, the distance, the slope, and the left and right slopes may be sequentially displayed.

If the slope is-37cm, the golf ball (2) to the hole cup (3) downhill and the height is 37cm, if the left and right slopes R 12cm from the position of the golf ball (2), the right is high, the left is low, the slope The accuracy should be putt by setting 12cm to the right of the hole as an imaginary hole.

In this case, the correction putting distance is introduced and introduced as a new concept.

The correction putting distance is a distance corrected in consideration of the current green speed based on a general green speed (for example, 2.4 m / sec).

For example, if the current green speed is 1.5m / sec and the distance between the golf ball and the hole cup is 3m, a putting distance of 1m at 2.4m / sec is 1

When defined as (Nuto), (2.4 / 1.5) X 3 = 4.8 Nuto is the correction putting distance.

Thus 4.8

Swing to the size of the swing that sends the correct putting distance of (Nuto).

Similarly, the correction putting distance is expressed in Nuto units in consideration of the slope (downhill, uphill) between the golf ball and the hole cup.

If the slope is-37 cm, the correct putting distance is 4.8-0.37 = 4.43 noto.
