Outdoor golf is prone to limit training or competitions due to factors such as field size, weather variations, etc. The indoor golf simulation device effectively solves the problem of outdoor golf, and can realize golf training or competition at any time, however, in the related art, the conventional golf simulation device can only randomly capture a user swing video, and further cannot allow the user to selectively upload the video. The user still needs a professional coach to give guidance and teaching beside the golf simulation device as the user does when training on an outdoor ground, which increases the training cost of the user.

Based on the technical problem, the application provides a golf swing video calling method, which can accurately obtain a complete video of a user swing and hitting a ball, and is convenient for the user to review the swing video of the user, and the user can perform self-correction on the swing action by matching with professional coach video comparison, so that the learning difficulty and the learning cost of golf movement are greatly reduced.

In general, video streaming refers to the transmission of video data that can be processed as a steady and continuous stream through a network, and in the embodiment of the present application, the video stream is captured by a camera module in a golf simulation device, and the video stream may be swing video and ball track video, that is, the video data that is transmitted and processed may be swing video and ball track video. The swing video is used for collecting the complete swing motion of a user, and the swing motion specifically comprises the following steps: the action of getting on the pole, the action of getting off the pole and the action of receiving the pole, the swing video of this embodiment collection promptly: the complete movement of the user from raising the club to hitting the golf ball with the club is recorded.

Specifically, when a user swings and hits a golf ball in a hitting area of an indoor golf simulation device, the method provided by the application may collect a complete swing motion of a user's backswing, downswing, and take-up by using a camera module of the golf simulation device, and generate a corresponding swing video through the simulation device. The track video is used for collecting the motion process of a golf ball hit by a user through swing, the user swings and hits the golf ball in a hitting area, a calculation module of the simulation equipment detects the swing action of the user and the motion state of the golf ball after being hit, the relationship between the face angle of the golf club, the motion track of the golf club and the motion instant speed track of the golf ball after being hit is calculated through algorithm analysis, and the basic data of the motion of the golf ball can be simulated and calculated: flight speed, flight deviation angle, takeoff angle, spin speed, and spin direction of the golf ball. The golf basic data are processed by the computing module, the flight trajectory data of the golf are computed, and a 3D engine in the simulation equipment renders the flight trajectory data of the golf into a virtual scene to form a track video.

For example, through the complete collection of the swing motion when the user exercises, the user can play back the own swing motion, the slow playing function of the video is matched with the slow playing contrast of the professional trainer video, the user can watch and analyze the defects of the own swing motion at any time, the user can conveniently improve the swing skill of the user at any time, and the technical ability of golf movement is improved.

Specifically, when a person is playing golf, according to a conventional swing motion, the backswing time does not exceed 2 seconds at most, and the downswing and backswing do not exceed 4 seconds at most, that is, in a captured video frame queue, the length of a backswing video frame is less than or equal to 2 seconds, and the total length of a downswing video frame and a backswing video frame is less than or equal to 4 seconds. In this embodiment, the video frame queue is formed in 6 seconds, which includes the up-link video that lasts for 2 seconds at most and the down-link and up-link video that lasts for 4 seconds at most. It is understood that when the posture of the video frame is detected and the swing motion is detected, the golf ball is hit, that is, the user has completed the backswing motion and the downswing motion, wherein the backswing motion lasts 2 seconds and the downswing motion lasts 0.5 seconds, so that when the swing motion is detected, the video frame of 2.5 seconds is collected, the video frame queue is extracted by delaying the extraction time of 3.5 seconds, and the video frame queue of 6 seconds including the complete backswing video frame, downswing video frame and take-up video frame is extracted.
