TECHNICAL FIELD [0001] The present invention relates to a method of providing green information using a photograph,

The present invention relates to a method of providing green information using a photograph and a terminal thereof, and more particularly, to a method and apparatus for generating green information by forming a three-dimensional image of a green image by image-based modeling, The present invention relates to a method of providing green information using a photograph that displays green information from a golf ball to a hole cup by matching an image of the green image and a terminal thereof.

The current golf market is largely divided into the United States and Europe. In Asia, the size of China's economy and the national income increase, so the golf population is increasing. However, because golf is difficult, Have fallen into recession, golf experts say.

On the other hand, Putting Green is a region where a golf ball is put into a hole cup with an average of 2 tares by rolling a golf ball into a lawn on a mat where a hole cup is formed.

In the case of putting in golf, it is necessary to grasp the lie on the green or the slope of the green accurately and strike the golf ball with appropriate intensity and direction to put the golf ball into the hole cup.

So putting has been the most important factor in the golf game because of its large impact on the score, and golfers step back several steps behind the ball to determine the lie between the golf ball and the hole cup before putting on the green Sit down or nearly match the ground and eye level to observe the green slope.

At this time, in order to grasp the intermediate inclination between the golf ball and the hole cup, observation from the left or right side, observation from the back side or back side of the hole cup, and grasping the minute lie around the hole cup are also indispensable operations for accurate putting.

In addition, in the case of professional golfers, the course where the game is played is rounded with the caddy in advance, and the caddy grasps the characteristics of each hole from time to time, thereby creating a yard book. In this case, it is difficult to get this help information, and because of the lack of ability to read the green slope, it is very difficult to put the golf ball in the putting green.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

It is to be noted that the same components of the drawings are denoted by the same reference numerals and symbols as possible even if they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Also, when a part is referred to as " including " an element, it does not exclude other elements unless specifically stated otherwise.

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

The method for providing green information according to the present invention is roughly divided into 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 original DB acquisition process, one or more photo zones (4) are designated by setting a position where the putting green can be photographed entirely around the putting green while showing the shape and characteristic points of the putting green (S102).

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

At this time, in order to detect the depth of the real image object (green), which is the information for acquiring the three-dimensional image, the photographing of the parallel visual stereo system and the cross virtual visual stereo system are performed, 1).

Terrestrial LiDAR (Terrestrial Light Detection and Ranging) The laser beam is emitted to a measurement object (green) by using a measuring device and the position information and image information of the object (green) are calculated by calculating the return time and phase difference And acquires combined three-dimensional spatial information.

A green image is stored in a computer or the like, and an image program is executed to generate a pure green image by removing additional images such as a hole position, a golf tool (e.g., a flag pin of a hole cup), and other human shapes (S106).

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

That is, the image is three-dimensionally imaged by image-based modeling that reconfigures the three-dimensional image by sensing the depth of the real image object from the two-dimensional green photograph, thereby generating the green information.

At this time, it is possible to calculate the three-dimensional image according to the depth and the depth of the three-dimensional object in at least two images based on the parallel visual stereo method or the cross visual stereo method, or to process the image obtained from one camera separately It can also be used as a 3D image.

For example, in the parallel vision stereo method, when two lens projection center lines are arranged in parallel, the image of the same object point is divided into an epipolar line (a line formed by two lens centers and an image plane) generated by the object point Wherein the depth of the real object can be sensed by the distance on the lens center and the focal distance and the distance between the projection objects on the image plane through the two lenses.

In the next three-dimensional green information, characteristic points such as a green edge and a green surrounding bunker are extracted and stored together with the three-dimensional green information (S112).

This feature point extraction is performed by face direction recognition or fingerprint recognition technology, and block direction extraction, binarization, and thinning are performed, and finally, feature point data is extracted.

After the three-dimensional green information including the minutiae is stored in the original DB constructed in the information providing server (not shown) through the steps described above, the information is provided to the green information providing terminal 10 and the specific information The 3D green information is downloaded and stored.

When the golf ball 2 is positioned on the green 1 in the course of actual information acquisition by the next user, the golfer moves to one or more of the designated photo zones 4, The actual green 1 is photographed (S114) so that the green edge 6, the golf ball 2, the hole cup 3, and the green surrounding bunker 5 are displayed using the camera 14 provided.

After removing additional images such as golf tools and other human shapes from the actual green picture, extract feature points such as the green edge 6 and the green surrounding bunker 5 to check the golf ball 2 and the hole cup 3, (2) and the position information of the hole cup 3 (S116).

The matching process is performed in such a manner that the image of the three-dimensional green information is compared with the image of the green image photographed by the golfer in the matching process, and the minutiae points of the step S112 and the minutiae of the step S116 are matched, 2) and the hole cup 3 is extracted as a relative value and then converted into an absolute position to be displayed on the image of the three-dimensional green information (S118).

Then, the entire image of the three-dimensional green information is displayed in the displaying process, and the three-dimensional green information from the golf ball 2 to the hall cup 3 is displayed on the display unit 18 of the information providing terminal 10 (S120).

At this time, a distance, a slope and a left / right slope between the golf ball 2 and the hole cup 3 may be displayed on one side of the display unit 18, and three-dimensional green information from the golf ball 2 to the hole cup 3 may be displayed And then display the distance, the tilt, and the left and right tilt in turn.

Here, if the slope is -37 ㎝, it is downhill from the golf ball (2) to the hole cup (3) and the height is 37 ㎝. If the slope is R 12 ㎝, the right side is higher and the left side is lower than the golf ball (2) You have to put the 12cm to the right of the hole by setting it as a virtual hole.

Here, the correction putting distance is newly introduced and displayed.

The corrected putting distance is a distance corrected based on the current green speed based on a normal green speed (for example, 2.4 m / sec).

(누토)라 정의할 때, (2.4/1.5) X 3 = 4.8 누토가 보정퍼팅거리가 된다.For example, if the current green speed is 1.5 m / sec and the distance between the golf ball and the hole cup is 3 m, the putting distance of 1 m from 2.4 m /

(Nuto), (2.4 / 1.5) X 3 = 4.8 Nuto is the corrected putting distance.

(누토)의 보정퍼팅거리를 보내는 스윙의 크기로 스윙하여야 한다.Therefore, 4.8

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

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

When the slope is -37 cm, the correction putting distance becomes 4.8-0.37 = 4.43 nto.
