Burnt process includes a focus process and secondary focus process, a focus process specifically: using shooting unit multiple the
One shooting height position photographic subjects object obtains the reference picture of corresponding first shooting height and position, selects clarity highest
Reference picture it is corresponding first shooting height and position as the first focal position.
Multiple first shooting height and positions, which refer to, terminates height and position positioned at preset first starting height and position 101 and first
Between 102, line-scan digital camera and/or object lens according to the first default step distance 103 vertically axis 104 from the first starting altitude position
It sets 101 and is moved to the first termination height and position 102, multiple first shooting height and positions of formation obtain corresponding first shooting
The reference picture of height and position, choosing finally terminate 102 line-scan digital camera of height and position in the first starting height and position 101 and first and clap
The corresponding first shooting height and position of the focus taken the photograph in the image of acquisition where selecting the highest image of clarity is defined as first
Focal position 105.
Secondary focus process specifically: choose the first focal position 105 and be used as the second center, obtained using shooting unit
The reference picture for taking multiple second shooting height and positions centered on the second center, selects clarity highest with reference to figure
As corresponding second shooting height and position is as the second focal position.
Multiple second shooting height and positions refer to centered on the second center, are located at preset second starting altitude position
201 and second terminate between height and position 202, and line-scan digital camera and/or object lens are according to the second default step distance 203 vertically axis
Line 204 is moved to the second termination height and position 202, multiple second shooting heights position of formation from the second starting altitude position 201
It sets.Wherein, the second default step distance 203 is less than the first default step distance 103, finally in the second starting altitude position 201
The focus pair where selecting the highest image of clarity in the image that the shooting of 202 line-scan digital camera of height and position obtains is terminated with second
The the second shooting height and position answered is defined as the second focal position 205.
S3 selects next mark point according to the first constraint condition, and focuses to it according to half focusing mode.
In a particular embodiment, the first constraint condition includes:
C0 is less than pre-determined distance threshold value with upper mark point distance；
C1, it is minimum with upper mark point distance；
C2 is located in the same connected region with a upper mark point.
Pre-determined distance threshold value d chooses with upper mark point distance less than pre-determined distance threshold value d to focus marks point,
Again from select meet C0 condition in focus marks point, selection is with a upper mark point apart from the smallest to focus marks
Point, and judge whether this mark point and a upper mark point are located in the same connected region, if being located at the same connected region
It is interior, then select this to wait for that focus marks point is focused as next mark point, and to it according to half focusing mode, if not being located at
In the same connected region, then find it is next meet the first constraint condition to focus marks point as next mark point.
In the present embodiment, judge whether to be located in the same connected region, specifically, by obtaining object original graph
Original image is converted to gray level image by picture, is carried out threshold filtering to gray level image, bianry image is converted into, to bianry image
Connected region is calculated, whether judge currently to choose is located at the same connected region to focus marks point and a upper mark point
It is interior.
In the present embodiment, half focusing mode specifically: with the focal position of previous mark point for the second center, hold
The secondary focus process of row.Due in step s 2, focusing to the first mark point according to full focusing mode, i.e., marked to first
Point first carries out a focus process, then carries out secondary focus process, since next mark point is selected according to the first constraint condition,
And focus to it according to half focusing mode, i.e., secondary focus process is clicked through to next label, due to marking with upper one
Point distance is less than pre-determined distance threshold value, i.e. focal length difference between two mark points is little, there is omitted herein a focus process,
The efficiency of camera scanning is effectively increased, while obtaining the higher image of clarity.
S4 repeats step S3.
In a particular embodiment, step S4 is to repeat step S3, until meeting the second constraint condition, wherein second
Constraint condition are as follows: at a distance from a upper mark point be greater than pre-determined distance threshold value.In the present embodiment, this method further includes step
S5: to mark point to be focused in object, the mark point to be focused from left end is to right end mark point to be focused according to a
It focuses according to full focusing mode.After executing step S1 to step S4, the mark that do not focus is likely present in object
Remember point, increases step S5 and focus to mark point to be focused in object according to full focusing mode, avoid due to front and back phase
The mark point of adjacent two focusings is apart from the case where too far, focal length difference causes to defocused fogging image greatly.
A kind of processing method of multiple labeling point target substance markers point focusing sequence of the present invention obtains and needs in object pair
Burnt mark point, determines that first mark point starts to focus, and next according to selecting with a upper mark point apart from the smallest condition
The focusing of a mark point, improves treatment effeciency, and to the mark point that different selection modes are selected, full focusing mode or half right is respectively adopted
