Abstract
The invention provides a video acquisition and processing method for javelin teaching and training in order to avoid the current situation that measurement methods of key parameters such as a javelin throwing elevation lack when people carry out the javelin 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 javelin teaching and training, so that the javelin 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 javelin English majours and processing method.
Background technology
When throwing a javelin, javelin sells the movement rate of moment javelin, the direction of motion of javelin, the throwing elevation angle of javelin, javelin when selling relative to the height on ground, the angle between javelin axis and spear sport direction, has a direct impact to the quality thrown a javelin.In addition, in the process that throws a javelin, the position etc. of the paces of personnel, run-up speed, hand-held javelin also produces material impact by the quality thrown a javelin.Because the moment thrown a javelin, the movement velocity of hand, javelin is very fast, only rely on human eye, people are difficult to the concrete motion conditions that even cannot obtain hand and javelin, therefore, in existing javelin English majours process, in most cases, people can only carry out instructing or training according to the roughly situation seen and the effect that throws a javelin.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 javelin 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 javelin, the invention provides a kind of video acquisition for javelin English majours and processing method, this technical scheme can the movement rate of convenient acquisition javelin, the important parameters such as direction of throwing out of javelin, for the analytic activity in javelin 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 javelin English majours and processing method.Thus provide datumization to support for the analysis improvement activity in javelin English majours.
Concrete technical scheme provided by the invention is:
For video acquisition and the processing method of javelin English majours, it is characterized in that, the method comprises the following steps:
Video image acquisition, carries out the video image of spear sport 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: relative at least one in the height on ground, angle between javelin axis and spear sport direction when described parameter comprises the movement rate of javelin, the direction of motion of javelin, the throwing elevation angle of javelin, javelin are sold.
Preferably: the surface of the javelin adopted in described spear sport 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 javelin 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 javelin provides analyzes data accurately, thus better promotes the English majours efficiency of javelin.
Accompanying drawing explanation
It is workflow diagram of the present invention shown in Fig. 1;
It is the javelin 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 spear sport 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 are separately positioned on runway terminal both sides, become 30 °, distance runway terminal 2.5m place with runway mid line angle, highly maintain an equal level with target person waist, for run-up and the process such as to throw a javelin of photographic subjects personnel; Two other camera is separately positioned on runway terminal both sides, becomes 30 °, distance runway terminal 2.5m place with runway mid line angle, is highly target person height, for taking the speed of throwing out of javelin, the motion conditions such as angle of throwing out.For better obtaining the sport video information of javelin, the javelin adopted in the present embodiment, its surface, as Fig. 2, the front and back rifle body of handgrip part is provided with cross-type mark.In practical operation, for being better convenient to the parameter measurement in later stage video analysis process, in surrounding, all mark can be set, and 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.Relative to the height on ground, the angle etc. between javelin axis and spear sport direction when desired parameters comprises the movement rate of javelin, the direction of motion of javelin, the throwing elevation angle of javelin, javelin 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 the situation of throwing a javelin, thus better suggest improvements, and improve English majours quality and the efficiency of javelin.
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.
