Abstract
The invention provides a video collecting and processing method for shot-put teaching and training in order to change the current situation that people lack measuring means for a shot-put throwing angle and other key parameters when carrying out shot-put teaching and training. According to the method, related parameters are automatically measured by collecting video images through the video processing technology, accurate analysis data are provided for shot-put teaching and training, and therefore the shot-put teaching and training efficiency is improved better.
Description
Technical field
The present invention relates to video acquisition and processing technology field, be specifically related to a kind of video acquisition for shot teaching and training and processing method.
Background technology
When throwing shot, shot sells the movement rate of moment shot, the direction of motion of shot, the throwing elevation angle of shot, shot when selling relative to the height on ground, has a direct impact to the quality of delivering.In addition, the change of throwing the body action such as paces, run-up speed of personnel in shot process also produces material impact by the quality of delivering.Because the moment of delivering, the movement velocity of hand and ball is very fast, only rely on human eye, people are difficult to the concrete motion conditions that even cannot obtain hand and shot, therefore, in existing shot teaching and training process, in most cases, people can only carry out instructing or training according to the roughly situation seen and delivery 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 elevation angle when shot is thrown out, 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 shot, the invention provides a kind of video acquisition for shot teaching and training and processing method, this technical scheme can the movement rate of convenient acquisition shot, the important parameters such as direction of throwing out of shot, for shot teaching and the analytic activity in training provide 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 shot teaching and training and processing method.Thus for shot teaching with training in analysis improvement activity provide datumization to support.
Concrete technical scheme provided by the invention is:
For video acquisition and the processing method of shot teaching and training, it is characterized in that, the method comprises the following steps:
Video image acquisition, carries out the video image of shot exercises 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.
Optimize, described video image acquisition is synchronously carried out by n camera, n be not less than 1 integer.
Optimize, relative at least one in the height on ground when described parameter comprises the movement rate of shot, the direction of motion of shot, the throwing elevation angle of shot, shot are sold.
Optimize, the surface of the shot adopted in described shot exercises is provided with the mark being convenient to video image analysis.
Optimize, the shape of described mark is at least one in point, striped, arrow, cross.
Optimize, described camera is high-definition camera.
Optimize, described camera is high-speed camera head.
Optimize, described camera is high definition high-speed camera head.
Optimize, described camera is depth of field camera.
Beneficial effect: a kind of video acquisition for shot teaching and training provided by the invention and processing method, by gathering video image and utilizing video processing technique automatically to measure relevant parameter, English majours for shot provides analyzes data accurately, thus better promotes the English majours efficiency of shot.
Accompanying drawing explanation
It is workflow diagram of the present invention shown in Fig. 1;
It is the shot 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 shot exercises 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 are separately positioned on 60 °, both sides, target person front, 2.5m place, and a camera is arranged on 2.5m place, target person rear, and these three cameras are used for the delivery process of photographic subjects personnel; Two other camera is separately positioned on 2.5m place, target person both sides, and height is concordant with target person shoulder, for taking the speed of throwing out of shot, the motion conditions such as angle of throwing out.
For better obtaining the sport video information of shot, the shot adopted in the present embodiment, its surface is as Fig. 2, and, front, rear, left and right six face upper and lower at shot is provided with cross-type mark.In practical operation, for being better convenient to the parameter measurement in later stage video analysis process, 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.Relative to the height etc. on ground when desired parameters comprises the movement rate of shot, the direction of motion of shot, the throwing elevation angle of shot, shot are sold, 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 delivery situation, thus better suggest improvements, and improve English majours quality and the efficiency of shot.
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.
