The authority distribution module further includes registration login module, logs in calibration system 6 for user, administrator steps on
It can Add User after record, permission is distributed to newly-increased user or carries out other desired operation.
As shown in figure 3, the demarcating module includes:
Preparation module, for creating task, defining semantic label；
Freehandhand-drawing demarcating module is treated calibration picture by hand drawing board for user and is demarcated；
Detection module, for being detected to calibration result.
As shown in figure 4, a kind of method for promoting Pixel-level calibration efficiency using hand drawing board, comprising the following steps:
S1 receives the picture of the shooting of camera 1 and generates picture library in server 2；
S2 accesses server 2 and enters calibration system 6, and synchronous picture library shows picture to be calibrated；
S3 identifies hand drawing board 4, and the operation interface of the calibration system 6 is mapped on hand drawing board 4；
S4 demarcates the picture to be calibrated by the Freehandhand-drawing pen 5, generates calibration result；
S5 detects the calibration result；
S6 generates corresponding demarcating file according to the calibration result.
In step S1, camera 1 shoots plurality of pictures, and picture is sent to server 2 and is saved, and server 2 is by all figures
Piece generates a picture library, distributes and saves convenient for subsequent calibration.It should be understood that the picture number in picture library is any
, picture number to be calibrated is less than or equal to the picture number in picture library, and administrator can delete, repair for picture
The operation such as change, increase newly.
In step S2, the end PC 3 accesses server 2, and enters calibration system 6, and the picture that needs are demarcated is shown, shows
The picture come is shown as picture to be calibrated, as shown in figure 5, include the following steps,
The newly-increased calibration user of A1 perhaps adding new administrators user and distributes to calibration user to demarcate permission or distribute to
Administrator is to demarcate permission, semantical definition permission, calibration task creation and delete permission, detection modification calibration result power
The calibration result permission that limit, calibration result generate permission, import inter-related task；
A2 creates calibration task, defines semantic label.
In step A1, administrator logs in calibration system, increases calibration user or administrator newly before calibration,
And assign its corresponding permission.Wherein, calibration user only demarcates permission, and administrator possesses but is not limited to above-mentioned steps A1
In permission.
In step A2, administrator creates task, imports the pictures for needing to demarcate, and semantic for pictures definition
Picture is distributed to the user for participating in calibration by label.
Wherein, need all pictures for demarcating comprising this in pictures, pictures by the newly-built management of administrator, with
File is unit, and the picture in pictures is imported from picture library, and the picture number in pictures is less than or equal to picture in picture library
Quantity.
In step S3, hand drawing board 4 is connected to the end PC 3 and picture to be calibrated is mapped to Freehandhand-drawing after the end PC 3 identifies hand drawing board 4
On plate 4, demarcated convenient for user.
Wherein, after the end PC 3 identifies hand drawing board 4, the interface at the end PC 3 is mapped to one by one on hand drawing board 4, demarcates user at this time
Mouse can be operated to carry out choosing picture, zoom picture, rotating image, switching picture or other desired operation, it is complete
After the operation before calibration, calibration user Freehandhand-drawing pen 5 can be used to demarcate.
In step S4, as shown in fig. 6, include the following steps,
B1 calibrates drop point of the Freehandhand-drawing pen 5 on hand drawing board 4, determines the initial position of calibration；
B2 responds user and is acted according to the mark that picture to be calibrated is labeled；
B3 generates corresponding annotation results according to mark movement, and the annotation results are corresponding with picture to be marked
It saves.
In step B1, hand drawing board 4 is connected to after the end PC 3, the calibration of Freehandhand-drawing drop point is carried out on hand drawing board 4, according to hand
The drop point of Freehandhand-drawing pen in the mobile observation calibration system of pen 5 is drawn to determine the initial position of calibration.
In step B2, determines to be moved up according to contour of object in hand drawing board after Freehandhand-drawing drop point and start to draw pen, in picture
The object for needing to demarcate carries out profile calibration.Demarcating user is the equal of simulating the behaviour for carrying out profile description with paintbrush on paper
Make, compared to mouse two o'clock at the calibration of line, operation of the invention is more simple, meets the habit of mankind's Freehandhand-drawing.It should be understood that
For hand drawing board used in the present invention and Freehandhand-drawing pen are external equipment, for being demarcated instead of mouse, commonly use scaling method
It is that mouse control cursor needs to demarcate and carries out click calibration on the profile of object on picture, and when mouse is demarcated is by adjacent two
It is connected between a point with straight line, and many objects to be calibrated are the profiles for having arc, therefore mouse calibrates the profile come
When not being bonded the original profile of object, cause the precision of calibration low, while demarcating user using mouse calibration, it may appear that operation is tired
Difficult, the problems such as being not suitable with, cause the efficiency of calibration very low, calibration user hand holds Freehandhand-drawing pen instead of mouse, Freehandhand-drawing in the present invention
Plate treats as drawing paper, is equivalent to calibration user and retouch side operation to object to be calibrated with paintbrush on drawing paper, with Freehandhand-drawing pen into
When row retouches side, side directly is retouched according to the original profile of object, more close to the profile of object, precision is higher, more efficient.
In step B3, after completing calibration, calibration result is saved with corresponding picture.
In step S5, including the detection of three steps, guarantee that calibration result is more accurate, as shown in fig. 7, comprises following steps,
Calibration user described in C1 carries out self detection；
Calibration user described in C2 is detected mutually；
Administrator described in C3 detects all calibration results.
When detection, detection for the first time carries out self-examination by currently demarcating user, and second of detection demarcates user by other
It is mutually checked, third time detection checks all calibration results by administrator.
In step S6, after the completion of detection, after the detection of three steps ensures that calibration result is errorless, by administrator to mark
Determine result and corresponding calibration picture generates corresponding demarcating file, and saves.
Then the present invention utilizes the Freehandhand-drawing pen of hand drawing board in hand on each pixel-map to hand drawing board of picture to be calibrated
It draws and classification to be calibrated in picture is carried out retouching side on plate, be similar on a width picture, with pen by classification interested on picture
Profile retouch one time, it is simple and convenient.The hand for demarcating user is closer from picture to be calibrated, and precision is easier to control.Mouse is replaced with pen
Mark control this behavior of cursor is more in line with mankind's habit, so easy to operate, calibration efficiency has significant improvement.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, according to the technical essence of the invention any simple modification made to the above embodiment, equivalent variations and modification, belong to
In the range of technical solution of the present invention.
