Description
Technical field
The present invention relates to gait Recognition technology more particularly to a kind of luggage case method is followed automatically based on Gait Recognition.
Background technique
According to " 2017-2022 China's Bag-making industry market development prospect and the investment opportunity of the publication of Zhong Shang industrial research institute
Research report " show that Chinese luggage market scale can reach 63.8 hundred million dollars and has pole Chinese Bag-making industry to 2020
Big market.Furthermore Bag-making industry is inseparable with national daily life, and a kind of gesture is presented in Chinese luggage articles demand
The growth trend that can not be kept off.Luggage case Brought Chinese People trip facilitate while, also more or less there are many drawbacks: for example when
When luggage is more, it will cause luggage case and pull trouble.Although the luggage case of present most model also has built-in steamboat, can
It is pulled with pull rod, but there are still be not easy the disadvantages of turning.Current scientific and technological industry flourishes, and every field starts towards intelligence
The directions such as change, summary and hommization are developed.But in terms of luggage case industry, there is also design old stuff, shortcoming intelligence etc. is asked
Topic, occurs electric trunk in the market and solves the above problem to a certain extent, but human-computer interaction is not strong, and its is high
Price also allow most of consumer groups to see and hope it.Most importantly safety problem, what most of traditional suitcase used
It is mechanical code lock, unavoidable luggage case is stolen, and is difficult to be tracked and give for change after stolen or loss.
For above-mentioned traditional suitcase there are the drawbacks of, a kind of following automatically based on Gait Recognition of the invention patent meter
Luggage case.The invention in conjunction with traditional suitcase, can improve biography using computer vision, modern electronic technology to a certain extent
Above-mentioned drawback existing for system luggage case, especially in terms of convenient trip, safe antitheft, the present invention is especially prominent.
Summary of the invention
The present invention provides a kind of to follow luggage case method automatically based on Gait Recognition, will be believed by the gait of analysis people
The method of breath identification identity is applied to multifunctional electric luggage case, and by being embedded in the camera module of luggage case system, record is worked as
The gait information of preceding user and compared with the gait information of user stored in monolithic hangar, if accuracy rate is higher than setting
Value, driving luggage case follow user mobile, and the function that automatic obstacle-avoiding detours is completed in moving process.Simultaneously in order to reduce near
The influence of passerby, the stolen accuracy rate that may and improve identification devise benefit on the basis of the luggage case follows module automatically
Front a small range user's walking posture is recorded with camera, user's identity is identified by multiple Gait Recognition, if
Multiple recognition accuracy is more than or equal to setting value, then driving motor follows user mobile.It is set if multiple recognition accuracy is lower than
Definite value then sends warning information and position coordinates to user mobile terminal by GPS positioning and GPRS communication module.Solution of the present invention
The problems such as existing luggage case heaviness of having determined is not portable, easy to be lost, often to go on business or the crowd of more long-distance travel being needed to provide just
It is prompt.
The purpose of the present invention makes full use of modern biotechnology feature identification technique, modern electronic technology and traditional luggage case picture
In conjunction with the safety for improving luggage case simultaneously, improves traditional suitcase and carries the problems such as trip is inconvenient.
To achieve the goals above, the present invention provides a kind of follows luggage case method automatically based on Gait Recognition, should
Method includes (being specifically shown in Fig. 4):
1. initially set up user's gait pattern library, by camera record user be respectively at immediately ahead of luggage case it is to the left,
Gait information to the right；
2. the target in pair video carries out detection and tracking, it is partitioned into human body；
3. extracting gait feature from movement using computer vision and image procossing related algorithm；
4. test is compared with the gait pattern library that training has stored using classifier, to complete Gait Recognition；
5. if driving single-chip microcontroller controls motor towards user's movement repeatedly Gait Recognition is correct, constantly carry out in the process
Gait Recognition judges whether it is user, and adjusts luggage case moving direction；
6. automatically follow user during, if repeatedly Gait Recognition accuracy rate be lower than setting value, can by GPS,
GPRS module sends warning information and current luggage case coordinate to user's mobile phone.
Based on foregoing invention method, there is difference and contribution outstanding to be compared with the conventional method:
It is combined 1. the present invention relates to a kind of biological identification technologies with traditional suitcase convenience, passes through gait Recognition technology
Judge that the gait information of user identifies whether to set user, and driving motor follows user and adjust automatically movement side
To convenient often to go on business or needing the crowd of long-distance travel to provide.
It combines 2. the present invention relates to biological identification technologies with traditional suitcase safety, is judged by gait Recognition technology
The gait information of user identifies whether to set user, if then following user automatically, if not then passing through GPS, GPRS
