Abstract
The utility model relates to a shot put measuring device based on rules and a view field geometric figure calibration technology. The shot put measuring device based on the rules and the view field geometric figure calibration technology is composed of a CCD (Charge Coupled Device) camera, a rack and a measuring computer, wherein the CCD camera is mounted on the rack and the CCD camera is connected with the measuring computer through a data line; and the measuring computer is internally provided with an image analyzing and measuring module, a measuring system database and an athlete information database. The shot put measuring device based on the rules and the view field geometric figure calibration technology can perform measurement in a shot put game in real time, has high measuring efficiency and an accurate measuring result, and is not interfered by artificial factors.
Description
Technical field:
The utility model relates in the sports device of measuring the shot putting distance, what be specifically related to is based on the shot measurement mechanism of rule with the geometric figure calibration technique of visual field.
Background technology:
The instrument of measuring distance is a lot of at present, and like infrared ambulator, radio distance-measuring set, but these instruments all can not be measured the cast of ammunition.At present the measurement of shot class ammunition cast is still drawing tape measure or at the method measuring distance of the throwing zoning equal portions line of ammunition in the sports, but these measuring method efficiency of measurement are low, and possibly there is the problem of cheating in measurement links.
Summary of the invention:
The purpose of the utility model provides the shot measurement mechanism of rule-based geometric figure calibration technique with the visual field, and it is used to solve the low problem of present shot class ammunition cast efficiency of measurement.
The utility model solves the technical scheme that its technical matters adopted: the shot measurement mechanism of this rule-based geometric figure calibration technique with the visual field is made up of ccd video camera, frame, metering computer; Ccd video camera is installed on the frame; Ccd video camera is connected with metering computer through data line, and graphical analysis measurement module, measuring system database, player information database are installed in the metering computer.
Metering computer is connected through LAN with an other computing machine of reporting achievement in the such scheme; The computing machine of reporting achievement is placed on place, sports ground rostrum; The metering computer analysis to measure finishes behind the fruit; Give the computing machine of reporting achievement through LAN with result transmission, the rostrum staff can report athletic throwing achievement in time.
The utlity model has following beneficial effect:
When 1, the utility model uses, frame and ccd video camera are placed into throwing field, obtain video image through ccd video camera; Extract shot drop point picture and be transferred to metering computer through data line, metering computer is mainly obtained the shot achievement according to measuring mathematical model, and shows through graphoscope; Can carry out the measurement of shot games results in real time; Efficiency of measurement is high, and measurement result is accurate, does not receive interference from human factor.
2, the result of the utility model measurement can be sent to sports ground rostrum staff place in time through network, makes sportsman and spectators in time obtain games results.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the view of ccd video camera images acquired in the utility model.
1 ccd video camera; 2 frames; 3 metering computer; 4 report the computing machine of achievement; 5 circles.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation:
In conjunction with Fig. 1, shown in Figure 2; The shot measurement mechanism of this rule-based geometric figure calibration technique with the visual field is made up of ccd video camera 1, frame 2, metering computer 3; Ccd video camera 1 is installed on the frame 2, and height-adjustable regulating device is installed on the frame 2, and ccd video camera 1 obtains video image through the video image acquisition system of self installing; Extract shot drop point picture; Ccd video camera 1 is connected with metering computer 3 through data line, and graphical analysis measurement module, measuring system database, player information database are installed in the metering computer 3, and metering computer 3 main completion according to measuring mathematical model are obtained the shot achievement; Metering computer 3 and other one computing machine of reporting achievement 4 are connected through LAN; The computing machine 4 of reporting achievement is placed on place, sports ground rostrum; Ccd video camera 1, frame 2, metering computer 3 are placed into the throwing field place; Frame 2 need be adjusted to suitable height, to collect the image of circle 5 easily.
The utility model course of work is following:
1. metering computer 3 is extracted player information: in the player information database, extract corresponding information through player number;
2. send and throw instruction: send which time trial throw instruction of XXX sportsman through the athletic ground loudspeaker,, record the whole process of throwing through video acquisition software startup ccd video camera 1;
3. obtain shot drop point picture: confirm the shot pick-up point and place target by the referee; Start the IMAQ program and take piece image through ccd video camera 1; Then the image that photographs is transferred to metering computer 3, metering computer 3 is saved in image in the file of appointment automatically;
4. measurement cast; The graphical analysis measurement module of metering computer 3 is demarcated the parameter of ccd video camera 1 according to the image planes position of RP in the background image (place shot target), and the physical coordinates of the setting up image grid matrix of planimetric coordinates accordingly; Image surface position according to the shot touchdown point; Confirm the ground level coordinate of shot according to grid matrix, export the result then, and show through display;
5. metering computer 3 is sent to place, sports ground rostrum with measurement result and reports in the computing machine 4 of achievement the report athletes ' performance.
