Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of and has seriality and the less leather area measurement apparatus of error.
The technical solution of the utility model is:
A kind of leather area measurement apparatus of CCD, it is characterized in that: include conveyer belt, motor, main frame, display, printer, lamp box, support and ccd image sensor, the feed end side of described conveyer belt is provided with main frame, described main frame (single-chip microcomputer) is provided with display and printer, described conveyer belt is connected by drive mechanism motor, described motor is motor, side in the middle part of described conveyer belt is provided with lamp box, the opposite side of described conveyer belt correspondence lamp box position is provided with ccd image sensor by support, the camera lens of described ccd image sensor is positioned at the top in the middle part of conveyer belt, it is provided with binarization circuit between described ccd image sensor and main frame；nullDescribed binarization circuit includes input port、Output port、Two electric capacity、Four resistance、One resistance、One potentiometer、One operational amplifier and a threshold values power supply，Described input port connects the first end of the first electric capacity and the first resistance respectively，Second end of described first electric capacity connects the second end of the first resistance respectively、First end of the second electric capacity and the first end of the second resistance，The input in the same direction of the second end concatenation operation amplifier of described second resistance，The reverse input end of described operational amplifier connects the first end of the 3rd resistance respectively、First end of resistance and the input of potentiometer，Second end of described second electric capacity、The outfan of potentiometer and the negative power end common ground of operational amplifier，The positive power source terminal of described operational amplifier connects the second end of the 3rd resistance respectively、Second end of resistance、First end of the 4th resistance and threshold values power supply，The outfan of described operational amplifier and the second end of the 4th resistance connect output port.
Leather area measurement need not gradation of image, uses binary conversion treatment can meet requirement.The output video signal of ccd image sensor accesses the input in the same direction of comparator, and threshold level, VREF access the inverting input of comparator, compared with threshold level VREF by video signal.When video signal is more than threshold level VREF, comparator is output as low level；When video signal is less than or equal to threshold level VREF, comparator is output as high level, can be represented with binary " 0 " or " 1 " by the video signal of tested district's point.Suitably adjust potentiometer VR, the size of threshold level VREF can be changed so that it is match with light illumination.The resistance of photoconductive resistance RG changes according to power change with ambient light, can compensate ambient light.
Ccd image sensor and motor co-ordination, often survey a leather motor to run 1 time, leather is sent to immediately below camera lens, after tested leather enters the camera watch region of people's imageing sensor, motor stops operating, and ccd image sensor is scanogram information under leather resting state.
Further, described lamp box is placed in directly over camera lens, and its effect is adequate illumination.
Further, described conveyer belt is the conveyer belt of white zone face, and its effect is to distinguish leather and zone face to greatest extent.
Further, described operational amplifier is LM311 voltage comparator.
The beneficial effects of the utility model are: this utility model makes leather transmission one can shoot scanning one by motor, serves a certain degree of seriality effect, allows to area statistics additionally by binarization circuit and be accurate to pixel scale.
