Abstract
The invention discloses a video collecting and processing method used for cricket teaching and training. The video collecting and processing method used for cricket teaching and training aims at solving the current situation that no means for measuring key parameters like ball board angles in the cricket hitting process exists in the process when people carry out cricket hitting teaching and training. Accurate analysis data are provided for cricket teaching and training by collecting video images and carrying out automatic measurement on relevant parameters through a video processing technology, and therefore the cricket teaching and training efficiency is better promoted.
Description
Technical field
The present invention relates to video acquisition and processing technology field, be specifically related to a kind of video acquisition for cricket English majours and processing method.
Background technology
When cricket, the angle of the movement rate of ball plate, the direction of motion of ball plate, square stance ball plate, and ball is hit the movement rate of rear ball, the direction of motion of ball, the rotation situation of ball, has a direct impact to the quality of batting.For the angle of square stance ball plate, when cricket angle is different, after the ball that impact front is sudden, have an impact to the heading of ball and flying speed.Because in the moment of batting, the movement velocity of human body, ball plate and ball is very fast, only rely on human eye, people are difficult to the concrete motion conditions that even cannot obtain human body, ball plate and ball, therefore, in existing cricket 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 cricket, the invention provides a kind of video acquisition for cricket English majours and processing method, this technical scheme can the important parameter such as movement rate, the rotation situation of ball, the angle of square stance ball plate of convenient acquisition ball, for the analytic activity in cricket 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 cricket English majours and processing method.Thus provide datumization to support for the analysis improvement activity in cricket English majours.
Concrete technical scheme provided by the invention is:
For video acquisition and the processing method of cricket English majours, it is characterized in that, the method comprises the following steps:
Video image acquisition, carries out the video image of cricket 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 movement rate, the direction of motion of ball plate, the angle of square stance ball plate of ball plate, and ball by hit in the rotation situation of the movement rate of rear ball, the direction of motion of ball, ball at least one.
Preferably: the surface of described ball is provided with the mark being convenient to video image analysis, described ball plate striking surface 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 cricket 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 cricket provides analyzes data accurately, thus better promotes the English majours efficiency of cricket.
Accompanying drawing explanation
It is workflow diagram of the present invention shown in Fig. 1;
It is the cricket that mark is set used in embodiment shown in Fig. 2;
It is the ball plate that mark is set used in embodiment shown in Fig. 3.
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 cricket by camera collection target person.For the video image that convenient acquisition is clear, complete, in the present embodiment, five high definitions depth of field camera is at a high speed adopted to take.Wherein two cameras 3m places, 45 ° of oblique uppers, Offered target personnel both sides respectively, for the motion conditions of the action of photographic subjects personnel, ball plate and ball; Two other camera is separately positioned on the both sides of target person, and height remains basically stable with the waist of target person, for taking the motion conditions of ball plate and ball; Remain a camera and be arranged on sportsman one proceeds posterolateral 45 °, distance about 2m position, height remains basically stable with sportsman's waist, for taking situation when ball flies here.For better obtaining the sport video information of cricket, the ball adopted in the present embodiment, its surface, as Fig. 2, arranges eight cross-type marks at its surface uniform; Equally, as Fig. 3, the striking surface of ball plate is provided with four cross-type marks.In practical operation, for better recording the rotational velocity of ball, the angle of square stance ball plate, each mark is 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 movement rate, the direction of motion of ball plate, the angle of square stance ball plate of ball plate, and ball is hit the movement rate of rear ball, the direction of motion of ball, the rotation situation etc. of ball, 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 cricket.
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.
