Referring to Fig. 7, another embodiment of the present invention also provides a kind of mowing system, including above-mentioned grass trimmer；Further include:
It determines the ditch or puddle of surface obstructions object or earth's surface recess in the boundary and harvesting region in harvesting region, and advises
Mark the processing unit of suitable exercise route；
Real-time display gathers in region terrain graph, the real-time positioning information of grass trimmer, harvesting area during cutting operation
The moving line in the ditch or puddle and grass trimmer of surface obstructions object or earth's surface recess is aobvious in the boundary in domain and harvesting region
Showing device；
It is mounted on grass trimmer, the real-time positioning information of grass trimmer is fed back into display device in harvesting region terrain graph
The real-time positioning apparatus shown；
It is provided in processing unit
Boundary determination unit determines the boundary in harvesting region according to harvesting region terrain graph；
Image segmentation unit is split harvesting region terrain graph, obtains surface obstructions object in the harvesting region
Or the ditch or puddle of the earth's surface recess；Described image cutting unit is split harvesting region terrain graph, specifically
It is:
By the incremental pixel of center to the edge gray value after the binaryzation for gathering in region terrain graph, extracted in image
The pixel region that region and center to edge gray value successively decrease, then therefrom select centered on pixel region center, withFor radius region as candidate region, wherein m is the pixel for including in each pixel region
Number, (xe,ye) it is most marginal pixel coordinate in each pixel region, (xc,yc) sat for the pixel at each pixel region center
Mark；
Calculate the average gray of rest of pixels in image after extracting each candidate region；
The average gray of each candidate region extracted is calculated, if the gray scale with rest of pixels in calculated image is flat
The difference of mean value is less than given threshold, then rejects corresponding pixel region from candidate region；Otherwise, by corresponding pixel region
Domain is retained in candidate region；
The pixel region being retained in candidate region, i.e., surface obstructions object or earth's surface recess in the described harvesting region
Ditch or puddle；
Route planning module: it is recessed according to surface obstructions object or the earth's surface in the boundary in harvesting region and harvesting region
Ditch or puddle, plan the moving line of grass trimmer, export to display device.
Surface obstructions object in harvesting area boundary and harvesting region is realized by boundary determination unit and image segmentation unit
Or the determination in the ditch or puddle of the earth's surface recess, the wherein determination of boundary determination unit can be obtained by unmanned plane
Harvesting region terrain graph carry out image procossing after determine.Gather in surface obstructions object or earth's surface recess in region
Ditch or puddle be determined as technological difficulties, because barrier can not be directly obtained from the harvesting region terrain graph that unmanned plane obtains
Hinder the accurate location information of object or ditch, puddle, it is therefore desirable to image segmentation be carried out to harvesting region terrain graph, by obstacle
Object or ditch, puddle are split from image, by analysis it is found that ditch, puddle gray scale often than harvested material (such as
Grass, wheat etc.) gray scale it is low, and barrier (such as slight slope, stone) is often higher than the gray scale of harvested material, in short, gray value
Being significantly lower than and being perhaps apparently higher than the part of harvested material gray scale is then likely to be barrier or ditch, puddle, therefore, elder generation
The binaryzation that region terrain graph will be gathered in extracts the pixel region that center to the edge gray value in image is incremented by, and
The pixel region that center to edge gray value successively decreases, then therefrom select centered on pixel region center, withFor radius region as candidate region, fully considered each with the candidate region that this is determined
Most marginal pixel coordinate in the number of pixels that includes in pixel region, each pixel region, each pixel region center picture
Plain coordinate, COMPREHENSIVE CALCULATING go out regional scope, as a result accurately, avoid the need for harvesting region and are accidentally deleted, calculate each time extracted
The average gray of favored area, if the difference with the average gray of rest of pixels in calculated image is less than given threshold,
Then corresponding pixel region is rejected from candidate region；Otherwise, corresponding pixel region is retained in candidate region；Retain
Pixel region in candidate region, i.e., the described ditch or water for gathering in surface obstructions object or earth's surface recess in region
Hole；The difference of average gray and the average gray of rest of pixels is less than setting threshold by the threshold value (such as 50) wherein set
The pixel region of value is judged to still falling within harvesting object area, it is deleted from candidate region, further Accurate Segmentation is as a result, keep away
Exempt from only by judging harvesting object area to candidate by accident in this judgment criteria acquired results of center to edge gray value increasing or decreasing
In region；So far the pixel region being retained in candidate region, i.e., surface obstructions object or the earth's surface in the described harvesting region
The ditch or puddle of recess.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
