Abstract
The invention provides a video acquisition and processing method for squash teaching and training in order to avoid the current situation that measurement methods of key parameters such as a squash autorotation rate lack when people carry out the squash teaching and training. The relevant parameters are automatically measured by acquiring a video image and utilizing a video processing technology to provide accurate analysis data to the squash teaching and training, so that the squash teaching and training efficiency is better improved.
Description
Technical field
The present invention relates to video acquisition and processing technology field, be specifically related to a kind of video acquisition for squash English majours and processing method.
Background technology
When playing squash, the direction of motion of the direction of motion of the batting movement rate of moment ball, ball, the movement rate of racket, racket, the angle of racket, ball and the position of racket contact point on racket, the movement rate of rear ball, the direction of motion of ball, the rotation situation of ball is hit by ball, and after ball and wall or earth surface, the movement rate of ball, the direction of motion of ball, the rotation situation of ball have a direct impact, and namely have a direct impact the quality of batting.In addition, in impact, the mode of hand-held racket, the change of body action also produce material impact by the quality of batting.Because in the moment of batting, the movement velocity of human body, racket and ball is very fast, only rely on human eye, people are difficult to the concrete motion conditions that even cannot obtain human body, racket and ball, therefore, in existing squash English majours process, in most cases, people can only carry out instructing or training according to the roughly situation seen and balling effect.This mode, has had a strong impact on the effect instructing and train.
For solving the problem, in prior art, people generally adopt the mode of viewing video carry out explaining and analyze.Although this improves English majours quality to a certain extent, still can not obtain the important parameters such as the rotation situation of ball, data supporting accurately cannot be provided for people, that is, still cannot obtain best English majours effect.
For better promoting the English majours effect of squash, the invention provides a kind of video acquisition for squash English majours and processing method, this technical scheme can the important parameter such as the movement rate of convenient acquisition ball, the rotation situation of ball, for the analytic activity in squash English majours provides datumization to support.
Summary of the invention
For the problems referred to above, the present invention, by gathering video image and utilizing video processing technique relevant parameter to be carried out to the mode automatically measured, provides a kind of video acquisition for squash English majours and processing method.Thus provide datumization to support for the analysis improvement activity in squash English majours.
Concrete technical scheme provided by the invention is:
For video acquisition and the processing method of squash English majours, it is characterized in that, the method comprises the following steps:
Video image acquisition, carries out the video image of squash motion by camera collection target person;
Video analysis, utilizes Video Analysis Technology to analyze described video image, obtains desired parameters;
Information exports, and is at least carried out the output of described parameter information by a kind of form in sound, word.
Preferably: described video image acquisition is synchronously carried out by n camera, n be not less than 1 integer.
Preferably: described parameter comprises at least one in the movement rate of the movement rate of ball, the direction of motion of ball, the movement rate of racket, the direction of motion of racket, the angle of racket, ball and the position of racket contact point on racket, the rotation situation of ball, the direction of motion of hand, hand.
Preferably: the surface of the squash adopted in described squash motion is provided with the mark being convenient to video image analysis.
Preferably: the shape of described mark is at least one in point, striped, arrow, cross.
Preferably: described camera is high-definition camera.
Preferably: described camera is high-speed camera head.
Preferably: described camera is high definition high-speed camera head.
Preferably: described camera is depth of field camera.
Beneficial effect: a kind of video acquisition for squash English majours provided by the invention and processing method, by gathering video image and utilizing video processing technique automatically to measure relevant parameter, English majours for squash provides analyzes data accurately, thus better promotes the English majours efficiency of squash.
Accompanying drawing explanation
It is workflow diagram of the present invention shown in Fig. 1;
It is the squash that mark is set used in embodiment shown in Fig. 2.
Embodiment
In order to more specifically describe the present invention, below in conjunction with the drawings and the specific embodiments, technical scheme of the present invention is described in detail.
As shown in Figure 1, first carry out video image acquisition, carried out the video image of squash motion by camera collection target person.For the video image that convenient acquisition is clear, complete, in the present embodiment, six high definitions depth of field camera is at a high speed adopted to take.One of them camera is arranged on above court, and its visual field comprises court, front wall; Another camera is also arranged on above court, and its visual field comprises court, target person; Two other camera is separately positioned on both sides, court, and its visual field is respectively the court wall of court and opposite side; Remain the both sides that two cameras are arranged on target person, for the motion conditions of the action of photographic subjects personnel, racket and ball.For better obtaining the sport video information of squash, the squash adopted in the present embodiment, its surface, as Fig. 2, is provided with cross-type mark in upper and lower, face, six, front, rear, left and right.In practical operation, for better recording the rotational velocity of squash, each mark can be arranged to different shapes, color.Afterwards, analyzed by the video content of computer to shooting that video analysis program is housed, measure desired parameters.Desired parameters comprises the movement rate of ball, the direction of motion of ball, the movement rate of racket, the direction of motion of racket, the angle of racket, ball and the position of racket contact point on racket, the rotation situation of ball, the direction of motion of hand, the movement rate etc. of hand, in actual applications, can carry out as required selecting or increasing.Computer gives record to measurement result, and exports as required.In the present embodiment, by computer display picture, the numerical value of mark parameters.Guidance or trainer, by above-mentioned numerical value, better can analyze batting situation, thus better suggest improvements, and improve English majours quality and the efficiency of squash.
It should be noted that, above embodiment, is understand method of the present invention and core concept thereof for helping; For one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
