The present invention relates to a method for providing green information using image matching, and a terminal thereof, and more particularly, to generate green information by three-dimensionalizing a green picture by image-based modeling, and to take an image of the green information and a golfer. The present invention relates to a green information providing method for displaying green information from a golf ball to a hole cup by matching an image of an actual green picture, and a terminal thereof.
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 exemplary embodiment of the present invention, FIG. 2 is an exemplary view of one green for explaining FIG. 1, and FIG. 3 is an exemplary view of an actual green for explaining FIG. 1.
The green information providing method according to the present invention mainly comprises a raw DB acquisition process (S102-S108), a user's actual information acquisition process (S110-S116), a matching process (S118), and a display process (S220).
First, the process of acquiring the circle DB can capture the entire putting green in the vicinity of the circle green (1) while setting a position that can show the shape and features of the putting green well by using the camera as well as the circle green (1) as well as the green edge ( 6), the entire green (1) is taken so that the green surrounding bunker (5), etc. (S102).
At this time, in order to detect the image depth of the real object (green), which is information for acquiring a 3D image, parallel stereo imaging and cross vision stereo recording are performed, or one green Shoot (1).
Or by using Terrestrial LiDAR (Terrestrial Light Detection And Ranging) surveying equipment, the laser beam is emitted to the surveying target (circle green), and the return time and phase difference are calculated to calculate the position information and image of the target (circle green). Acquiring three-dimensional spatial information combining the information.
The original green picture is stored in a computer or the like, and the image program is executed to remove the additional images such as the
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 (S106).
That is, green information is obtained by imaging in three dimensions by image-based modeling, which reconstructs three dimensions by detecting the depth of the real object from a two-dimensional circle 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 three-dimensional green information, feature points such as green edges and green surrounding bunkers, which are the characteristics of the green, are extracted, or patterns of specific regions are extracted and stored together with the three-dimensional green information (S108).
This feature point extraction uses face recognition or fingerprint recognition technology to perform block direction extraction, binarization, thinning, and finally, feature point data is extracted.
The pattern extraction converts an image of 3D green information into a binary image and extracts a pattern from a specific region of the binary image.
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
Next, when the golfer is located on the actual green 7 shown in FIG. 3 when the golfer rounds as a user's actual information acquisition process, the green edge using the
Remove the additional image, such as golf tools, the shape of the person from the actual green picture (S112).
A feature point is extracted from the actual green picture from which the additional image is removed, or a pattern of a specific region is extracted from the actual green picture (S114).
In addition, the golf ball and the hole cup are identified in the actual green picture from which the additional image is removed to generate position information of the golf ball and the hole cup (S116).
In the following matching process, the image of the 3D green information and the image of the green picture taken by the golfer are compared with each other, and the matching is performed by matching the feature points or patterns of step S108 with the feature points or patterns of step S114, The positions of the
After displaying the entire image of the 3D green information in the display process, the 3D green information from the
In this case, the distance between the
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)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.
