The invention provides a kind of shooting using light searching object profile and scratch drawing method, including: environment light is regulated to the first darkness；The background picture in shooting background region under described first darkness；Subject is put in described background area；Under described first darkness, shooting has the first picture of described subject；Described background picture and described first picture are carried out image subtraction computing to obtain contour of object figure；Environment light is regulated to normal exposure brightness；Under described normal exposure brightness, shooting has the second picture of described subject；Carry out described first picture and described second picture scratching figure computing to obtain the subject picture without background.The present invention by being combined as a whole existing capture apparatus and corresponding auxiliary facility with each processor and software platform, control to realize automatically scratching figure in the way of hardware by software, it is possible to realize high discrimination, high efficiency, high-quality, i.e. clap and i.e. scratch the feature of figure.
Description
Technical field
The present invention relates to image processing field, scratch figure side particularly to a kind of shooting using light searching object profile
Method.
Background technology
Manually draw contour of object carry out manually scratching figure it is known that traditional stingy figure mode one is professional person, this
Sample not only speed is slow, and specialty requires height, and after scratching figure, picture quality is poor, and also one is exactly that software identifies that object is taken turns automatically
Exterior feature, although this sample loading mode speed is fast, but discrimination is relatively low, and especially object color and background colour is closer to or object wheel
Wide more complicated irregular time almost None-identified, picture quality is not highly desirable.
Summary of the invention
The invention provides a kind of shooting using light searching object profile and scratch drawing method, to solve prior art is scratched
The problem of plot quality difference.
For solving the problems referred to above, as one aspect of the present invention, it is provided that a kind of light searching object profile of using
Drawing method is scratched in shooting, including: environment light is regulated to the first darkness；The background in shooting background region under described first darkness
Picture；Subject is put in described background area；Under described first darkness, shooting has described subject
First picture；Described background picture and described first picture are carried out image subtraction computing to obtain contour of object figure；By environment
Light regulates to normal exposure brightness；Under described normal exposure brightness, shooting has the second picture of described subject；
Carry out described first picture and described second picture scratching figure computing to obtain the subject picture without background.
Preferably, the method also includes including the regulation of environment light to the first darkness: utilize first processor to control
Second processor of light box brightness sends the first instruction；Regulate the brightness of light box according to described first instruction by the second processor.
Preferably, described subject is placed on transparent pallet when shooting described first and second picture.
Preferably, described second picture uses reversible-light shooting.
Preferably, when shooting described first and second picture, the position of the most described background area of described subject
Angle constant.
Preferably, described first processor is that single-chip microcomputer, ARM, MCU, PLC, computer or mobile phone etc. are constituted.
Preferably, the data that described first processor controls photographing device by usb bus, wifi are transmitted.
Preferably, the photographing device such as slr camera, digital camera, motion cameras, photographic head, mobile phone shoots described background

The present invention is by existing capture apparatus and corresponding auxiliary facility and each processor and software platform
It is combined as a whole, light, image subtraction computing, stingy nomography is combined very well, realizes in the way of software controls hardware
Automatically figure is scratched, it is possible to realize high discrimination, high efficiency, high-quality, i.e. clap and i.e. scratch the feature of figure, it is possible to effectively meet individual, enterprise
Industry uses to be needed.
Accompanying drawing explanation
Fig. 1 schematically shows the flow chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can be defined by the claims
Implement with the multitude of different ways covered.
The principle of the present invention is: according to optical principle, and object can be caused under object is in backlight environment to expose not
Foot-shape becomes the profile of black, image subtraction computing to be to be compared by two pictures, can be the two different places of pictures
Find out, then, in the environment of dark situation backlight, obtain a Background, a background and object figure just can pass through subtraction
The profile diagram obtaining object of computing.And scratch graphic calculation rule and need to obtain the profile diagram of object and just can carry out scratching figure, for terrible
To a high-quality picture, need to obtain one when carrying out and scratching nomography computing and expose picture accurately, then be accomplished by
Again light is transferred to suitable brightness and obtains a high-quality picture, eventually pass stingy nomography obtain final object without
Background.
As it is shown in figure 1, the invention provides a kind of shooting using light searching object profile to scratch drawing method, including: will
Environment light regulates to the first darkness；The background picture in shooting background region under described first darkness；Subject is put
Enter in described background area；Under described first darkness, shooting has the first picture of described subject；By described background
Picture and described first picture carry out image subtraction computing to obtain contour of object figure；By bright to normal exposure for the regulation of environment light
Degree；Under described normal exposure brightness, shooting has the second picture of described subject；By described first picture and described
Second picture carries out scratching figure computing to obtain the subject picture without background.
Owing to have employed technique scheme, the present invention by existing capture apparatus and corresponding auxiliary facility and
Each processor and software platform are combined as a whole, and light, image subtraction computing, stingy nomography are combined very well, with
Software controls the mode of hardware and realizes automatically scratching figure, it is possible to realizes high discrimination, high efficiency, high-quality, i.e. clap and i.e. scratch the spy of figure
Point, it is possible to effectively meet individual, enterprise uses needs.
Preferably, the method also includes including the regulation of environment light to the first darkness: utilize first processor to control
Second processor of light box brightness sends the first instruction；Regulate the brightness of light box according to described first instruction by the second processor.
