Abstract
The invention discloses a monitoring-based ball trajectory capture and feedback system. The system comprises a double-layered grating system, a control master and a projected image. According to the monitoring and feedback system, defects of the prior art are overcome, on the basis of an infrared correlation grating detection system, moving trajectory of a ball can be detected in the moving process of the ball, the impact point of the ball can be prejudged, and the system image responds timely.
Description
Technical field
The present invention relates to ball track monitoring technical field, specifically belong to based on the ball track capturing of monitoring and reponse system.
Background technology
Existing ball track capturing and reponse system majority are based on infrared camera detection technique on the market, and the shortcoming of this system is that the response time is slow, and picture postpones obviously, to be vulnerable to the image of surrounding environment light, poor user experience.
Summary of the invention
The object of this invention is to provide based on the ball track capturing of monitoring and reponse system, overcome the deficiencies in the prior art, based on infrared emission Grating Detecting System, the movement locus of spheroid can in spheroid motion process, just have been detected, judge in advance the drop point of spheroid, system interface response in time.
The technical solution used in the present invention is as follows:
Based on the ball track capturing of monitoring and reponse system, this system is comprised of double-layer grating system, main control system and projected picture.
Described optical-mechanical system, is comprised of the two-layer grating in front and back, and every layer of grating is again by laterally forming with vertical two groups of correlation light sensors.
5 centimetres of the spacing of arranging between described light sensor.Like this when every one deck grating is crossed by zuqiutong,, 4-5 light sensor make-and-break signal laterally and vertically triggered in capital, we add up rear average to triggering the position of light sensor, and we just can draw when football flies over this one deck grating like this, residing horizontal and vertical coordinate.And the front and back position of every one deck grating self we be known, I can just can monitor out two the space coordinates points of football in flight path like this.
Described main control system adopts 2,4 or 8 KPCI-849 boards, and every board can external two D37 data port.Can support at most to gather 64 road signals, two boards card just can be monitored 128 tunnel grating signals simultaneously so simultaneously.In practice, if need more high-precision location point to detect demand, we can adopt 4, and even 8 KPCI-849 boards, realize thereby further strengthen raster density.Main control system, obtains two space of points positions in football flight course by two-layer grating, and considers the image of gravity, just can simulate the Live Flying track of football.
Projected picture, has set up a three-dimensional pitch model, and has adopted first person, to front projection's curtain, allows experiencer feel virtual projection scene image projection, is the extension of real space environment.After the full ball of taking seriously is pounded on projection screen, in virtual three-dimensional scene, can relay there is a virtual football, and be endowed the flight path of the true football that we detect, and then can finally judge experiencer's whether success of shooting.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention is based on infrared emission Grating Detecting System, the movement locus of spheroid can in spheroid motion process, just be detected, judge in advance the drop point of spheroid, system interface response in time, the technical program is less than 5 centimetres to the locus error judgment of football, response speed is less than 10 milliseconds, is obviously better than traditional camera head monitor scheme.

The specific embodiment
Referring to accompanying drawing, based on the ball track capturing of monitoring and reponse system, this system is comprised of double-layer grating system 1, main control system 2 and projected picture 3; Optical-mechanical system, is comprised of the two-layer grating in front and back, and every layer of grating is again by laterally forming with vertical two groups of correlation light sensors 101; 5 centimetres of the spacing of arranging between light sensor 101, like this when every one deck grating is crossed by zuqiutong,, 4-5 light sensor make-and-break signal laterally and vertically triggered in capital, we add up rear average to triggering the position of light sensor, we just can draw when football flies over this one deck grating like this, residing horizontal and vertical coordinate.And the front and back position of every one deck grating self we be known, I can just can monitor out two the space coordinates points of football in flight path like this.
Described main control system 2 adopts 2,4 or 8 KPCI-849 boards, and every board can external two D37 data port.Can support at most to gather 64 road signals, two boards card just can be monitored 128 tunnel grating signals simultaneously so simultaneously.In practice, if need more high-precision location point to detect demand, we can adopt 4, and even 8 KPCI-849 boards, realize thereby further strengthen raster density.Main control system, obtains two space of points positions in football flight course by two-layer grating, and considers the image of gravity, just can simulate the Live Flying track of football.
Projected picture, has set up a three-dimensional pitch model, and has adopted first person, to front projection's curtain, allows experiencer feel virtual projection scene image projection, is the extension of real space environment.After the full ball of taking seriously is pounded on projection screen, in virtual three-dimensional scene, can relay there is a virtual football, and be endowed the flight path of the true football that we detect, and then can finally judge experiencer's whether success of shooting.
