Technical field
The invention belongs to taximeter automatic Verification technical field, and in particular to a kind of taximeter calibrating is used
Visual sense sampling system and its calibration method.
Background technology
Existing taximeter verifying process flow is such：After taxi enters calibrating station, sailed by verification worker guiding
On the verification table of upper taximeter verification system, and by fee register reading back to zero.Verification worker starts on verification table afterwards
Mileage assay device, verification table start to rotate with taxi front-wheel, the actual row of the taxi that taxi verification system is collected
Sail distance to start to increase.Period verification worker pays close attention to taximeter reading always, when reading reaches default certified value, presses
RF remote-controlled collection key, sends collection signal to taximeter verification system.Taximeter verification system is received adopts
After collection signal, current taxi actual travel rice number is recorded, with fee register read-around ratio compared with obtaining the actual mistake of taximeter
Difference, so as to judge whether taximeter error is qualified.
This kind of verifying process flow, the sampling of taximeter mileage reading are completed by human eye, have following asking using artificial sample
Topic：Firstth, people is digital to remote keying needs certain response time is pressed from fee register display screen is seen, according to data, people
The General reactions time be 0.3 second, this will cause certain systematic error.Secondth, people due to fatigue or external environment divert one's attention,
When fee register display screen numeral is beated, not necessarily can at once it is noted that the error that causes of such case be possible to can be very big.
The content of the invention
The technical problem to be solved in the present invention is：A kind of taximeter calibrating visual sense sampling system and its inspection are provided
Determine method, so as to reduce taximeter gauging error.
The technical scheme is that such：
First, the present invention proposes such a taximeter calibrating visual sense sampling system, and the system is by installing
Constitute with pattern recognition device in-car image collecting device is hired out.The system is supporting with taximeter verification system to be made
With.The data acquisition unit includes fee register fixture, and the fee register fixture is provided with wireless camera and for wireless to this
The rechargeable battery that photographic head is powered, wireless camera are sent out the data for gathering by wireless signal；Described image identification dress
Put including wireless signal receiver, host computer and radiofrequency launcher.
Wherein, the fee register fixture is removably mounted on taximeter, and wireless camera positive alignment is hired out
Car fee register display screen.
Image recognition software of the host computer equipped with the data of having the records of distance by the log for being used to identify fee register display screen.
Taximeter Visual Sampling calibration method is carried out using this system to comprise the steps：
Step 1：After taxi enters the verification table at calibrating station, taximeter reading is zeroed；
Step 2：Fee register fixture is installed on taximeter, the wireless camera positive alignment on fee register fixture is made
Taximeter display screen simultaneously proceeds by image acquisition；
Step 3：Start the mileage calibration equipment on the verification table at calibrating station, verification table starts to turn with taxi front-wheel
Dynamic, the actual mileage of taximeter verification system start recording taxi simultaneously, is hired out on in-car fee register fixture
The image of the newest reading that taximeter display screen is constantly shown by wireless camera is passed by way of wireless signal
Return host computer；
Step 4：When the image recognition software system identification of host computer reaches default certified value to taximeter reading
When, software sends collection signal to taximeter verification system by radiofrequency launcher；
Step 5：After taximeter verification system receives collection signal, by the current taxi of record mileage calibration equipment
Car actual travel mileage with by the fee register read-around ratio of wireless camera collection compared with obtaining the actual mistake of taximeter
Difference, so as to judge whether taximeter error is qualified.
Taximeter display screen is shown numerical sample automatization using image recognition technology by the present invention, can be avoided
The error that these anthropic factors are caused, mitigates the work load of staff, and improves calibrating efficiency.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the system is made up of with pattern recognition device the image collecting device installed in taxi in-car.This is
System supporting with taximeter verification system 8 is used.Described image harvester includes fee register fixture 2, and the fee register is pressed from both sides
Tool 2 is provided with wireless camera 3 and for the rechargeable battery 4 to the power supply of wireless camera 3, and wireless camera 3 is by wireless
Signal is sent out the image for gathering；Described image identifying device includes that wireless signal receiver 5, host computer 6 and radio frequency are sent out
Emitter 7.As shown in Fig. 2 fee register fixture 2 is removably mounted on taximeter 1,3 positive alignment of wireless camera goes out
Hire a car 1 display screen of fee register.Image recognition software of the host computer 6 equipped with the data of having the records of distance by the log for being used to identify fee register display screen is simultaneously
And host computer 6 realizes signal transmission with taximeter verification system 8 by video transmitter 7.
Embodiment 1：
As shown in figure 1, after taxi enters calibrating station, reaching verification table by verification worker guiding.Then verification worker will be valuated
