For it is known that in this, as benchmark.Or after having set up light source 430 and image-taking device 420, the image in the capture region figure is shot
The lines of known length are equipped with as in, then calculating benchmark.After calculating benchmark, the system of length can be carried out by statistical pixel
Meter.
The working method of this system:
Step 1 inputs sawing parameter by the human-computer interaction device of controller 200.
In technique requirement, different plate can be cut out according to different needs, as it is desirable that rectangular plate, similar
Rectangular plate, lumber recovery requirement is too high, and offset is big, and the plank that may become a useful person there is the situation of a small amount of round edge, it is desirable that rectangle
Then to set lesser offset, it is therefore desirable to certain offset is done on the basis of calculating data, to realize peak efficiency
Lumber recovery.Offset can be inputted from man-machine interface.User according to oneself need determine the need for offset and partially
The size of shifting amount.For the ease of human-computer interaction, controller is typically provided the human-computer interactions such as keyboard, display or touch screen dress
It sets.
It preferably, in this step, further include the proportionality coefficient for obtaining actual size and picture size, specifically:
After step 1.1, on-line measurement device are fixed, standard calibration is placed in the capture region of image-taking device 420,

Machine 300 handles image, calculates the image data of standard calibration card,
Step 1.3, manual measurement standard calibration card calculate actual size and figure according to the data of standard calibration card
The proportionality coefficient of size as in,
The proportionality coefficient obtained in step 1.3 is stored in system by step 1.4, is used to subsequent calculating.
Step 2, controller 200 control the mobile stupefied plank in slope of the opposite saw blade of image-taking device 420 and carry out continuous capture.
Wherein, the travel speed of plank, capture interval, camera frame rate are rolled over according to desired technological parameter and economy
Middle selection is divided into 14mm between capture in this fact Example when 60 frames of camera frame rate/second, travel speed >=50m/min.If wanted
Speed is improved simultaneously and reduces capture interval it is necessary to increase frame rate, while needing to improve between controller and industrial personal computer 300
The transmission rate of data.
The image data that step 3, image-taking device 420 will acquire sends industrial personal computer 300 to.
Step 4, industrial personal computer 300 carry out analytical calculation to all images by image processing program, obtain each position
The image data of the stupefied plank in the slope set, and determine the parameter of most narrow rectangle plank, specifically:
The step the following steps are included:
Step 4.1, PaintShop obtain it is similar it is trapezoidal in each line segment and trapezoidal high pixel number, and then
The image pixel data of capture region interior line obtains the length of the line segment in image according to pixel data,
Step 4.2 handles each image, obtains the length data of Xn1, Xn2, Xn3, Xn4, Hn in image,
Wherein n is positive integer,
Or, calculating real data at this time, just do not calculated in step 4.4.
Step 4.3, the size for comparing Xn2, Xn3 obtain the minimum value Xmin3 of the maximum value Xmax2, Xn3 of Xn2,
The width of most narrow rectangle plank is Lnu=Xmin3-Xmax2,
In the step, when judging maximum value Xmax2, when obtaining a maximum value Xmax2, this position Xn1 can determine whether
Length whether be greater than the point Xn2 length, if it is greater than then maximum value be the point Xn1 length.Equally judging most
When small Xmin3, when obtaining a minimum value Xn3, need to judge whether Xn4 is less than Xn3, if it is less than then selecting Xn3.That is:
Xmax2 is selected in Xn1, Xn2, and Xmin3 is selected in Xn3, Xn4.
Step 4.4 is calculated using the image size data obtained in the proportionality coefficient and step 4.3 obtained in step 1.3
Actual size data out.
In this step, the trapezoidal of acquisition can further be converted into actual size according to angle in Fig. 4.In practice, because
The problems such as installing angle cannot use calculated coefficient conversion physical length in applying step 1 when the mode calculated.
The parameter of most narrow rectangle plank is sent to controller 200 by step 5, industrial personal computer 300.
Step 6, controller 200 are according to the sawing parameter of input and the state modulator saw blade adjustment mechanism of most narrow rectangle plank
Driving device 500 to change the sawing position of circular saw bit.
If the driving device 500 of saw blade adjustment mechanism is servo electrical machinery system, controller output generates corresponding speed
Spike train with position is to servo electrical machinery system, to change the position of circular saw bit.
If the driving device 500 of saw blade adjustment mechanism uses common variable-frequency motor system, controller 200 is continuously detected
Saw blade position, and control according to the speed of the position control variable-frequency motor of saw blade and start and stop the position of circular saw bit.
