Problems solved by technology
[0004] 1. As a detection target, it is difficult to detect accurately because the football is too small;
[0005] 2. Due to the changeable flight direction of the football, it is difficult to detect accurately;
[0006] 3. In the football shooting detection system, in addition to the speed, the shooting angle and arc are also important parameters to measure, but this solution is difficult to detect the shooting angle and arc of the football flight

The invention relates to a juvenile football shooting quality detection method which is characterized by comprising the following steps: scanning and recording student number information of students on RFID (radio frequency identification) bracelets by an RFID check-in system, transmitting the student information to a high-performance workstation, starting to scan images obtained by a first high-speed camera and a second high-speed camera after the workstation obtains the prompt, and analyzing the student actions; synchronously transmitting the images of the first and second high-speed cameras to the high-performance workstation, and operating to obtain the shooting angle, speed and radian information by the high-performance workstation; tracing and fitting the football track in the high-performance workstation, and extracting several pieces of key information of the football sports; establishing an objective and actual football shooting scoring system with high operability in the check-in record system of the high-performance workstation, analyzing an excellent shooting element and weight thereof, and giving the shooting scores of the students. The method disclosed by the invention has the advantages that the shooting evaluation manner is comprehensive, the football speed can be detected, the shooting angles and football flying curves can also be detected, the usability is high, and long-term student data can be analyzed.
Description
technical field [0001] The invention relates to a method for detecting the shooting quality of youth football. Background technique [0002] At present, radar is generally used to measure the shooting speed of football. [0003] Radar speed measurement is to obtain the moving speed of the measured object based on the calculation of the frequency shift of the received reflected wave; that is, to set up a radar transmitter next to the road, transmit the radar beam to the flying football, and then receive the reflected echo. The ball speed is measured by echo analysis, and then calculated according to the speed. The disadvantages of this scheme are as follows: [0004] 1. As a detection target, it is difficult to detect accurately because the football is too small; [0005] 2. Due to the changeable flight direction of the football, it is difficult to detect accurately; [0006] 3. In the football shot detection system, in addition to the speed, the angle and arc of the shot ...
