Detailed Description
The invention discloses a method for accurately detecting a hitting position in billiard sports, which comprises the following steps: firstly, in the early stage of the table tennis striking exercise, the target striking position is positioned and photographed by adopting high-speed camera equipment, and the positioning photographing process is as follows: the method comprises the steps of placing a ball to be hit on a target position, carrying out static photographing through high-speed photographing equipment, and analyzing photographed pictures through a software system to form initial target position information. Then, when the billiards is hit and exercised, a trigger line is set in the software system, the hit ball is subjected to position tracking shooting in the hitting process by utilizing high-speed camera equipment, and the high-speed camera equipment is triggered to carry out high-speed shooting on the hit ball position by taking the hit ball passing through the trigger line as a trigger condition. And finally, calculating the actual hitting position information of the photographing result through a software system, comparing the actual hitting position information with the initial target position information to obtain deviation information, feeding the deviation information back to a practicer in a chart and voice broadcasting mode, and finishing the accurate detection process of the hitting position. The high-speed camera shooting equipment can be a smart phone or a computer with a camera. Through the accurate detection of batting position once and again and according to the testing result, the practitioner can carry out batting position adjustment at any time to accomplish batting exercise process fast, accurately.
The first embodiment is as follows:
the invention will be described in further detail below with reference to the practice of the striking position of the billiard cue side and the accompanying drawing 1:
the invention discloses a method for accurately detecting a hitting position in billiard sports, which comprises the following steps:
step 1, the smart phone is arranged above a pool side exercise area of the billiard table through a support, the shooting visual field range of the smart phone is adjusted, and the shooting effective range is set according to the shooting visual field range in the smart phone APP system.
The effective range 2 is set based on the position of the side of the pool which may be hit during the practice of hitting the ball. In this example, the effective range 2 is defined in the smart phone APP system in a manual selection manner. Of course, the effective range 2 should lie within the shooting field of view 1.
The height and the shooting angle of smart mobile phone can be adjusted to the support. In this example, the smartphone supported on the stand is located on the inclined side of the practice area, and the normal batting practice process is not affected.
And 2, automatically generating a coordinate system in the smart phone APP system according to the effective range, and setting a corresponding trigger line for high-speed shooting.
After selecting the effective range in smart mobile phone APP system, can the automatic generation coordinate system in the APP system, then according to the position and the effective range 2 in exercise area, artifical setting is used for the trigger line 3 of high-speed shooting in the APP system, and the quilt of 3 trigger lines hits the spheroid and can trigger the smart mobile phone and carry out high-speed shooting.
The trigger line 3 can be set to a boundary of the active range or a specified limit within the active range 2, which can be freely set in the smartphone APP system according to actual exercise needs.
And 3, placing the ball to be hit at the position to be hit, photographing and teaching the smart phone APP system to form initial target position information, namely a basic zero point.
In order to determine an accurate hitting position, in the early stage of practice, a ball to be hit needs to be placed at the accurate position to be hit, then image acquisition and confirmation are carried out in a photographing mode, and finally initial target position information, namely the basic zero point of the practice process, is formed in an intelligent mobile phone APP system and is used for comparison in the follow-up practice process. In this example, the position of the basic zero point is a certain position of the side of the exercise area. Of course, the hitting position exercise may be an exercise of hitting any area on the table top.
And 4, during ball hitting practice, when a ball to be hit passes or touches a trigger line for high-speed shooting, starting high-speed shooting by the smart phone, determining deviation between a hitting position and a basic zero point by analyzing the captured picture and the established coordinate system, forming a data report and voice broadcasting, and completing the accurate detection process of the hitting position.
In the embodiment, the practice of the ball hitting position at the warehouse side is based on the accuracy of the walking position after the ball to be hit is hit, the practice is compared with the basic zero point based on the warehouse side position in the ball to be hit, so that the position deviation data in the practice process is formed, and the position deviation data is fed back to a practitioner in a way of broadcasting at any time, so that the practitioner can adjust at any time in the practice process, meanwhile, the position deviation data can be summarized, the practice process is recorded by shapes such as charts, and data support is provided for further improvement and improvement. The method is particularly suitable for the practice process of multiple fixed-point batting in table tennis sports, and greatly improves the efficiency of the batting position practice process.
