Abstract
The invention provides a video acquisition and processing method for ice hockey teaching and training in order to avoid the current situation that measurement methods of key parameters such as an ice hockey autorotation rate lack when people carry out the ice hockey 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 ice hockey teaching and training, so that the ice hockey 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 ice hockey English majours and processing method.
Background technology
When playing ice hockey, the angle of the movement rate of bar sword, the direction of motion of bar sword, bar sword, ball and the position of bar sword contact point on bar sword, ball and the position of bar sword contact point on ball, and ball is hit the movement rate of rear ball, the direction of motion of ball, the rotation situation of ball, have a direct impact to the quality of batting.In addition, in impact, the mode of hand-held ball cutter, the change of body action also produce material impact by the quality of batting.Certainly transfer example to ball, when ice hockey time rotational, will have an impact to the running route of ice hockey.Because in the moment of batting, the movement velocity of human body, ball cutter, bar sword 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 cutter, bar sword and ball, therefore, in existing ice hockey 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 ice hockey, the invention provides a kind of video acquisition for ice hockey 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 ice hockey 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 ice hockey English majours and processing method.Thus provide datumization to support for the analysis improvement activity in ice hockey English majours.
Concrete technical scheme provided by the invention is:
For video acquisition and the processing method of ice hockey English majours, it is characterized in that, the method comprises the following steps:
Video image acquisition, carries out the video image of ice hockey 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 the movement rate of bar sword, the direction of motion of bar sword, the angle of bar sword, ball and the position of bar sword contact point on bar sword, ball and the position of bar sword contact point on ball, 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 the ice hockey adopted in described ice hockey 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 ice hockey 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 ice hockey provides analyzes data accurately, thus better promotes the English majours efficiency of ice hockey.
Accompanying drawing explanation
It is workflow diagram of the present invention shown in Fig. 1;
It is the ice hockey 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 ice hockey by camera collection target person.For the video image that convenient acquisition is clear, complete, in the present embodiment, four 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 cutter and ball; Two other camera is separately positioned on the both sides of ball, and height is concordant with ball, for taking the motion conditions of bar sword and ball.For better obtaining the sport video information of ice hockey, the ice hockey adopted in the present embodiment, its surface is as Fig. 2, and in front, rear, left and right, four faces are provided with cross-type mark.In practical operation, for better recording the rotational velocity of ice hockey, 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 bar sword, the direction of motion of bar sword, the angle of bar sword, ball and the position of bar sword contact point on bar sword, ball and the position of bar sword contact point on ball, 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 ice hockey.
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.
