C, upper single-chip microcomputer and computing machine usb circuit
In order to simplify the power supply mode of peripheral circuit, upper single-chip microcomputer adopts usb bus and computing machine to communicate.Single-chip microcomputer sends the data to the USB mouth by serial ports, and this mouth is converted to usb protocol with data, and sends to computing machine; USB interface receives the data that computing machine is sent, and is converted into the serial ports form and sends to single-chip microcomputer (Fig. 4).3 line system serial communication modes have been adopted in the present embodiment.The USB modules driver is installed will make the newly-increased virtual serial mouth of computing machine (for example, COM3), operation to the USB mouth, the serial port programming on the similar computing machine of programming operation promptly finished in the operation of this virtual port.
Image timing subsystem of the present utility model is made up of image pick-up card and high speed linear array CCD video camera, shooting control module and automatic interpretation unit, and application image is handled and mode identification technology, has realized shooting control, timing and automatic interpretation function.Take the mode of operation of control module configuration image capture card 6, thereby realize setting and control, specifically take flow process as shown in Figure 5 high speed linear array CCD video camera 7.After obtaining athletic meeting final spurt image, read in this image, carry out the human body location, and then be converted to games results, and preserve the spurt image of band interpretation achievement by the automatic interpretation unit.
The interpretation method of the utility model automatic interpretation unit mainly comprises human body coarse positioning and two steps of trunk fine positioning.Human body coarse positioning flow process concrete steps are as follows:
(1) the utilization edge detection operator is handled athletic meeting final spurt image, and the marginal information of human body image is detected, and draws edge detection graph.
(2) adopt suitable structural element to carry out expansion process, make the zone of the connection of human body image formation in the edge detection graph.
(3) the circulation zone bit is set, the expansion results figure of edge detection graph is carried out vertical projection and horizontal projection to determine position and the record of human body image on vertical direction and horizontal direction, realize the human body coarse positioning.
According to coarse positioning information, roughly human body target is extracted from former figure.Then the human body coarse positioning figure that extracts is further handled, realize the trunk fine positioning.Trunk fine positioning concrete steps are as follows:
(1) human body coarse positioning figure is carried out binary conversion treatment, human body image part and non-human body image part are separated effectively.
(2) carry out the mathematical morphology opening operation, remove noise spot.
(3) carry out vertical projection, calculate the projection average, obtain threshold value.The part that is higher than this threshold value is thought trunk, judges the reference position and the record of trunk.
(4) the trunk position information that is write down according to (3) extracts roughly trunk from opening operation figure, obtain trunk coarse positioning figure.
(5) structure template is calculated the white pixel of representative's volume image among the trunk coarse positioning figure and is counted, and is that template is wide with the width of trunk coarse positioning figure, counts divided by the wide value that is obtained of template as the template height with white pixel.
(6) slide from top to bottom in trunk coarse positioning figure with the template of being constructed in (5), seek among the trunk coarse positioning figure in the template area size white pixel count out maximum zones and the positional information of record template this moment in trunk coarse positioning figure;
(7) positional information that writes down in the basis (6) extracts the respective regions among the trunk coarse positioning figure, tentatively draws trunk fine positioning figure;
(8) vertical projection is carried out in resulting zone in (7) once more, finally realize the trunk fine positioning, write down this position, and the corresponding achievement discriminant line that in photographic images, draws.
In addition, when occurring human body adhesion serious situation in the photographic images, differentiating automatically can the bigger error of appearance.Therefore system has the manual adjustment program, allows the judge that achievement interpretation line is carried out manual adjustment, thereby guarantees the accuracy of achievement.
Information management unit of the present utility model is not only preserved and rank the achievement of differentiating, and also provides information management service for athletic meeting simultaneously.Develop software voluntarily and write foreground program, DAO is a database interface, and the ACCESSES database is operated.In taking subroutine, by automatic interpretation or after manually judgement obtains athletes ' performance, select current athletic race Taoist monastic name, just can realize achievement is saved in corresponding sportsman's record, after finishing, match can realize automatic name arranging.The information management unit compatible mutually with the image timing subsystem can be provided with contestant, group, race-entry project, organization arrangement, integration, award, gives race arrangement person very big degree of freedom.And system goes for the athletic meeting of number of different types.For special event, as non-medal sport, as shuttlecock kicking, bicycle is ridden slowly etc. and can be set its rule accordingly, and system supports self-defined event, with track record.
The corresponding information management of the utility model realizes by DAO interface and sql like language operating database, not only can freely set the multiple information in sports events, sports rule and the match, also can make blank entry blank by the Excel interface, be distributed to each group, by each incorporation's typing player information voluntarily.The entry blank of each group is collected the back read in data message automatically by the Excel interface.If wherein information is filled in mistake or disagreed with rule, for example the registration item exceeds setting value, and system will provide prompting and require and correct.In competition schedule and sportsman's layout, corresponding data processing is arranged all, and the result is write in the database.Competition schedule can be provided with competition sessions, time and group.Sportsman's layout has manually and automatic two kinds of selections.Automatic editing adopts the mode to sportsman's Random assignment, promptly distributes by producing random number, and repeatedly random number guarantees to avoid same unit to meet in same group as far as possible.In layout, also have layout in the match, advance semifinals and finals layout etc. as preliminary contest.The preferential layout of achievement is adopted in this class layout, and promptly achievement is forward enters next round.All will produce ranking list automatically after the every game, by ranking decision next round list.Simultaneously, information management unit has also been set the function of manual modification.
The content that is not described in detail in this instructions belongs to this area professional and technical personnel's known prior art.
