Embodiment
This below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out it is clear,
Complete description, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its
His embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, a kind of long distance laser derusting that the embodiment of the present application provides monitors in real time and feedback method, it is described
Comprise the following steps:
Step S101:Obtain derusting design sketch;
The derusting design sketch is to treat the image progress continuous acquisition of derusting metal surface with certain frequency and obtain
Image.
Step S102:Derusting design sketch is subjected to gray proces, obtains gray level image;
Gray scale refers to pure white, black and a series of intermediate colors from black to white in both.Gray scale highest is equivalent to highest
It is black, be exactly black.Gray scale is minimum black equivalent to minimum, i.e., pure white.Typically, with a byte come table after pixel value quantifies
Show.The gray value for there are black-ash-white consecutive variations is such as quantified as 256 gray levels, the scope of gray value is 0-255, is represented bright
For degree from depth to shallow, the color in correspondence image is from black to white.Black-and-white photograph contains all gray tones between black and white,
Each pixel value is one kind in 256 kinds of gray scales between black and white.
Step S103:Calculate the average gray value of unit area on gray level image;
The gray level image got is calculated, obtains average gray value.The average gray value calculating method can be with
It is arithmetic average gray value, geometric average gray value, root mean square average gray value, harmonic average gray value, weighted average gray scale
Value etc..
Step S104:The average gray value and derusting grade gray threshold set in advance are contrasted, it is determined that derusting area
The derusting grade in domain;
The derusting grade gray threshold experiment set in advance obtains.Corrosion metals plate is carried out using sand paper
Different grades of derusting, then collection derusting surface image, obtains average gray value, according to reality after equally carrying out gray proces
The required derusting effect reached, gray threshold is set.Such as common corrosion steel plate, carry out grinding without grade with sand paper
After derusting, gather image and calculate gray threshold.
According to the calculating gray threshold and derusting effect, the derusting grade is set.Such as one-level derusting gray value is
130-160, two level derusting gray value are 160-190, and three-level derusting gray value is certain higher grade derusting effect more than 190
Better.The threshold value of the derusting grade of setting is the derusting grade gray threshold set in advance.
When the gray scale that derusts is 170, derusting grade is two level, and derusting works well;When the gray scale that derusts is 200, derusting
Grade is three-level, and derusting effect is very good.
Step S105:Judge derust region derusting grade whether meet demand;
Staff presets the derusting grade of meet demand, by contrast the metallic plate derusting grade with it is described pre-
The derusting grade of the meet demand first set.
Step S106:If the derusting grade in derusting region is unsatisfactory for demand, repeating said steps after operational factor are adjusted
S101 to the step S105;
When the metallic plate derusting grade is less than the derusting grade of the meet demand set in advance, as derust area
The derusting grade in domain is unsatisfactory for demand, need to readjust operational factor, then repeating said steps S101 to the step S105;
Until derusting grade of the metallic plate derusting grade more than or equal to the meet demand set in advance, stop described in repetition
Step S101 to the step S105, carry out next step.
Step S107:If the derusting grade meet demand in region of derusting, calculate and obtain the derusting surplus working hours and remove
Rust efficiency.
When derusting grade of the metallic plate derusting grade more than or equal to the meet demand set in advance, as remove
The derusting grade meet demand in rust region, is calculated by the computer and obtains surplus working hours and the rust cleaning efficiency of derusting.
Pass through formulaThe surplus working hours are calculated, S in formula0For the default metallic plate gross area to be derusted, S1For
Derust area, and v is sweep speed, and d is sweep span, and t is the surplus working hours.
Pass through formulaRust cleaning efficiency is calculated, t in formula0For with the derusting time.
Tested specifically, completing once derusting with feedback method by a kind of long distance laser derusting monitoring in real time.
Pre-set derusting grade, intensity value ranges 130-160 are one-level, and intensity value ranges 160-190 is two level, and gray value is more than
190 be three-level, and higher grade, and derusting effect is better.Experiment purpose is to obtain three-level derusting effect.
Will metallic plate be derusted, after being derusted, operational factor be sweep speed 1000mm/s, sweep span 0.01mm,
Laser power 2W, laser frequency 20kHz.Rust design sketch is obtained, picture is subjected to gray proces, it is 132 to obtain average gray value,
Judge that derusting grade is only one-level;Then operational factor is adjusted, laser power 4W, remaining parameter constant, obtains derusting effect again
Fruit is schemed, and picture is carried out into gray proces, and it is 164 to obtain average gray value, judges that derusting grade is two level;Continue adjustment operation ginseng
Number, laser power 4W, remaining parameter constant, rust design sketch is obtained again, picture is subjected to gray proces, obtains average gray value
For 198, judge that derusting grade is three-level, reach experiment purpose.
A kind of long distance laser derusting provided in an embodiment of the present invention monitors in real time and feedback method, is adopted in real time by analysis

Gray value is calculated in × B.Such as R=208, G=210, B=199, pass through the formula P=0.3 × R+0.59 × G+0.11
× B=0.3 × 208+0.59 × 210+0.11 × 199=208 calculates each grey scale pixel value by the formula.
Specifically, step S103:Calculating the average gray value of unit area on gray level image includes:According toCalculate average gray value.The gray value of each pixel passes through the formula P=0.3 × R+
What 0.59 × G+0.11 × B was calculated goes out, then according toCalculate average gray value.Such as
P1=208, P2=186, P3=185, then P=(208+186+185)/3=193
Specifically, according to step S106:If the derusting grade in derusting region is unsatisfactory for demand, weight after operational factor is adjusted
The multiple step S101 to the step S105 includes:According to ρ=Pav/ ftvd, adjust operational factor.
It should be noted that described be adjusted to adjust in real time.
ρ=the PavIn/ftvd, ρ is energy density, PavIt is laser frequency for laser power, f, t is pulsewidth, v is to sweep
Speed is retouched, d is sweep span, and wherein pulsewidth t can be considered constant.
Specifically, the operational factor, including laser frequency, sweep speed, sweep span.I.e. described laser frequency, institute
It is customized parameter to state sweep speed and the sweep span.
Specifically, methods described also includes:Derusting speed is judged by sweep speed and the product of sweep span.
