Description
Technical field
The present invention relates to a kind of match timekeeping system and clocking method, especially a kind of track automatic timing system and timing
Method.
Background technique
Currently, usually whether breast the tape using Artificial Cognition sportsman in track timekeeping system and obtain games results,
Identification uses manual operation, needs to expend a large amount of manpowers, and when sportsman is when breasting the tape, is difficult in the case that gap is small
Accurate games results out, it is therefore desirable to a kind of track timing device that can replace traditional manually evaluating score, to improve timing
Efficiency and accuracy.
In the prior art, track timekeeping system is roughly divided into three kinds, and one is the sides using infrared ray or laser bracing wire
Formula a little blocks sportsman breasting the tape, and principle is the light sensitive characteristic using electronic component, i.e. people blocks light beam in final spurt,
Change circuitous resistance characteristic, to carry out timing, metering.This method can only record the time that sportsman breasts the tape, and can not judge
The corresponding runway of each sportsman, and when more people make a spurt simultaneously, the status requirement that laser beam is irradiated to human body is harsh,
Finally there is still a need for people to intervene, low efficiency of scoring, and probability of miscarriage of justice is big.
There are also the method for using signal source to incude record games results, and each runway terminal point is handled using computer
The data that signal receiving device transmits record the motion profile of sportsman with this, when sensor monitors that sportsman reaches eventually
When point, score terminates to obtain games results, and the influence that this method signal interference and human body block etc. to achievement is very big, Er Qiejing
Exactness is low, when more people breast the tape the small situation of games results gap simultaneously, can not obtain accurate games results.
There are also handling sportsman using image recognition technology to breast the tape the equipment of picture, and this method is existed due to sportsman
To show that accurate motion picture needs to carry out high-precision especially when sportsman's level gap is small in high-speed motion
Image Acquisition and image processing and analyzing, to the dynamic menu acquisition capacity of image capture device and the place of image-data processing apparatus
It is extremely harsh to manage Capability Requirement, and satisfactory Image Acquisition and image-data processing apparatus are sufficiently expensive, do not meet small-sized
The requirement of the application scenarios such as either daily match, such as school sports either track Physical Examination.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technical problems, and without manual intervention when providing a kind of judgement achievement,
Score is accurate, and must achieving the result, the time is short, and equipment is cheaply economical, meets various application scenarios requirements, based on image recognition
