In the present embodiment, optionally, the described first object 400 to be processed is octagonal.
In the present embodiment, optionally, the described first object 400 to be processed is triangle.
In preferred the present embodiment, the first laser engraving operation includes: that the first roughhew carves operation and the second thin carving
Carve operation；
First roughhew carves operation
The laser head 105 for controlling the laser engraving module 100 is moved to the first roughhew and carves height；Wherein, described first
Roughhew carves the first focal length that height is greater than the laser head 105 to described first to the first distance on foundry object surface；
According to the default laser engraving track to match with first laser engraving operation, and open the laser head
105, it controls the laser head 105 and described first object 400 to be processed is carved；
Described second, which carefully carves operation, includes:
After the completion of carving operation in response to first roughhew, from 105 direction of laser head, it is to be processed to acquire described first
First image of object 400；
According to the gray value F (x, y) of each pixel of the first image, each institute in the first image is obtained
State the first degree of burning of each point on the default laser engraving track corresponding to pixelWherein, F (x, y)=0,1,2 ..., 255；X is stated, y is respectively the seat of the pixel
Scale value；
According to the first degree of burning Q1(x,y), solve and preset on laser engraving track described in the described second thin engraving
Each point described in laser head 105 compensation height hbc；The compensation height hbcMeet:The α is that experiment solves preset value, and the β is that experiment solves preset value, the α
> 0, the β > 0；
According to the default laser engraving track and the compensation height hbc, the laser head 105 is controlled to described first
Object 400 to be processed is carved.
It is noted that being to be based in the present embodimentFirst is obtained to burn
Degree, this is because brightness vision variation meets Weber-Fechner law, if image minimum brightness is Lmin=L1, then human eye can divide
The second level brightness distinguished are as follows: L2=(1+ ξ) L1, third level brightness are as follows: L3=(1+ ξ)2L1, N grades are LN=(1+ ξ)N-1L1,
In, N is tonal gradation, 0 < ξ < 1.Grayscale and brightness meet exponential distribution, for high gray and low ash rank, phase
With ash scale, the luminance difference of the two is different.And laser burn also complies with the variation, for the pixel of high gray, first burns
The slope of focal power is higher, and for the pixel of low ash rank, the slope of the first degree of burning is lower, and the slope and exponential function
It is related.
Laser engraving really converges to laser in focus, and is heated, according to laser focal whether converge to
In machining object, heating power is also different；By controlling the distance between laser head 105 and object to be processed, realize different sharp
Light scribe power.
In the present embodiment, it is carved by secondary laser, after the first roughhew in first time carves operation, passes through acquisition first
Image judges that the first roughhew carves the first degree of burning of each position in operation process, is then set in the according to the first degree of burning
Laser head 105 needs the compensation height h moved down at various locations in two thin engraving operationsbc, so that after secondary laser engraving, laser
Carve post-job pattern can uniform hue, overcome the problems, such as foodstuff object uneven surface to be processed.
Specifically, the degree of burning of laser engraving is positively correlated with laser energy, it is inversely proportional, swashs with the facula area of laser
Light facula area and spot radius square are inversely proportional；Meanwhile being greater than at a distance from object surface to be processed in control laser head 105
In the case where 105 focal length of laser head, difference in height between 105 focal length of laser facula radius and object surface to be processed and laser head at
Direct ratio is carved in operation so can obtain in the first roughhew:
Meanwhile in the second thin engraving operation, it can obtain:
It can be obtained by formula (1), (2):
Formula (3) deformation can be obtained:
It is noted thatIt can be obtained by default experiment, also, in actual scene, laser head 105 is sent out
Laser out can not pool a bit, but a hot spot is presented, and can incite somebody to actionSwash as what laser head 105 issued
Data when light focuses are used as positive burnt equivalent coefficient,The sum of be definite value when, it is believed that swashing twice
Point gray value after light engraving is identical；So can setting valueThat is:
Furthermore, it is only necessary to the difference in height of front and back laser engraving twice is solved, then by difference in height as compensating height hbc
Laser head 105 is adjusted, the second thin engraving operation can be carried out；Compensate height hbcMeet:
hbc=Δ h1(x,y)-Δh2(x,y) (6)
First degree of burning Q (x, y) carries out conversion solution by gray value, and the Q (x, y) meets:
Wherein, F (x, y)=0,1,2 ..., 255；
It can be obtained by formula (1):
Wherein,For definite value, it can be solved and be preset by experiment；It enablesAnd set preset value；
It can obtain:
It can be obtained by formula (5):
Simultaneous (6), (9), (10) can obtain:
Formula (9) substitution (11) can be obtained:
Formula (7) substitution (12) can be obtained:
