(1) be loaded into the image of needs, by user's labelling two point on the image be loaded into, these 2 the straight line acquiescences formed are as reference line, and its plane length system assigned value is x;
(2) numerical value defined by the actual scale of surveyors' staff, as length of the scale, carries out physical length definition to this reference line, and meanwhile, acquiescence physical length assignment is y; Confirm that this assignment turns (4);
(3) utilize length of the scale to carry out after physical length has defined can select to redefine, as redefined, be back to (2) and adjustment length of the scale can be selected to obtain physical length assignment, as confirmed, then this assignment is locked; (4) measure lesion locations, metering system adopts 2 labellings and to 2 straight line acquiescences of carrying out line as reference line, now its plane length system assigned value is z1, and many lines are then according to z1, z2, z3 ... the like;
(5) computing formula (zx)/y is utilized to calculate this physical length of 2; Z refers to above-mentioned z1, z2, z3 respectively;
(6) result calculated forms data 1, the data 2 of one or more line
(7) result measured then can be back to (5) be chosen as remeasured calculating;
(8) final result is presented as data 1, data 2 ...
Two points of user's continued labelling are the 2 paired points of next direct-connected line of the formation being considered as continuous pairs, and being needs the line 2 of measurement size and automatically form acquiescence as the straight line with reference to line.
The invention has the beneficial effects as follows: by proposing the measuring method of lesion tissue size under a kind of scope, the image obtained under can choosing arbitrarily scope, easy and directly compare the measurement obtaining in endoscopic image and organize, as long as obtain piece image, need not calculate by video image.By User Defined survey tool numerical value, carry out polymarker to the image imported, handy P-2-P technology, forms straight line automatically, compares acquisition numerical value between points with the actual scale of surveyors' staff; And the numerical value of User Defined survey tool can be reset.Application is convenient, and good measuring accuracy.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention.
Detailed description of the invention
As shown in Figure 1, length of the scale: refer to the numerical value defined according to the actual scale of surveyors' staff under scope.
The measuring method of lesion tissue size under scope, under scope imaging obtain image basis on, the image of acquisition is the orthographic view of pathological changes or lesion tissue, takes following steps:
(1) be loaded into image, image is the orthographic view of pathological changes or the lesion tissue obtained after imaging under scope.Its image defines without strict form, but its size default definition is the normal size of imaging under scope.This image need meet 1, have intersection containing the lesion tissue of imaging under ruler tool 2, ruler tool and its scope in image or be in plumbness 3 with lesion tissue, scale label is clear;
(2) choose reference line, system needs after being loaded into image to carry out choosing of reference line to the image in loading system.The step chosen is any labelling two point, system default using the straight line of this point-to-point transmission as with reference to line.In order to make the result of measurement more accurate, the generally acquiescence of choosing of this reference line gets intersection or the diameter of ruler tool under scope in imaging of ruler tool and lesion tissue.Length in its (projection) plane is x by system assigned value;
(3) define length of the scale, because ruler tool has actual scale mark, the reference line intercepted in the picture can obtain the length of reference line reality according to the scale on actual ruler tool, this length y defines;
(4) whether confirm this value, after definition length of the scale, system can be confirmed whether this value to determine, measuring process of being allowed for access after determining, as uncertain, can reset and to choose original reference line and the definition of length of the scale operates again;
(5) measurement straight line is chosen, namely measuring process is entered after confirmation above-mentioned steps, marked lesion organization edge place any two points, system default is using this straight line of 2 as a length value (generally choose the length of lesion tissue and wide), and the length of its (projection) plane is z by system default assignment;
(6) apply mechanically formula, utilize computing formula i.e. (zy)/x in proportion
(7) generate data 1 and 2, automatically generated the physical length of point-to-point transmission straight line, can carry out repeatedly generating many results after labelling forms many straight lines according to above-mentioned formula by system, it can be only can generate twice measurement data that this system default only gives twice measuring machine;
(8) (in measuring process) last labelling can be returned as remeasured lesion tissue size, thus obtain new measurement data;
(9) generate result, final system represents that result is data 1, data 2, also can be data 1 ╳ data 2;
Under scope of the present invention, pathological changes is measured and is also comprised:
Can import by unrestricted choice scope hypograph;
Can by the length of the scale of User Defined survey tool numerical value;
Polymarker can be carried out to the image imported;
Utilize P-2-P technology, automatically form straight line, obtain numerical value between points with the actual scale of surveyors' staff;
The numerical value of User Defined survey tool can be reset;
Last image tagged can be returned.
Click image red area and can select image place catalogue,
Reinsert image by a function key (as F5);
After image is chosen, start mapping specification below; Conjunction measuring scale carrys out the self-defined acquiescence length of the scale wanted, and this length will as system default value, and after pressing confirming button, system can automatically lock the numerical value of input, and now length of the scale input frame is Lycoperdon polymorphum Vitt, cannot make an amendment operation.
Flow process is provided with function of reset, operates after completing determination operation before need cancelling, then click and reset, namely again can customize length of the scale.
Although the present invention with preferred embodiment disclose as above, so itself and be not used to limit the present invention.Persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is when being as the criterion depending on those as defined in claim.
