The basic procedure of the method for the calibrating optical Coherence tomography image edge line of the embodiment of the present invention with reference to figure 1, can mainly comprise the steps that S101 is to step S104:
S101, determining that user is current needs the optical coherence tomography OCT image border line of correction and 3 reference mark for describing controlling curve.
In embodiments of the present invention, controlling curve can be 2 Beziers.The characteristic of 2 Beziers is that use 3 points can determine 2 Beziers.In order to describe a controlling curve, 3 reference mark describing this controlling curve can be determined in advance, comprising intermediate control point, initial reference mark and finishing control point.
The determination at reference mark needs with current optical coherence tomography (the OpticalCoherence Tomography needing to correct of user, OCT) image border line be defined as basis, namely, the current OCT image border line corrected that needs of user is determined prior to reference mark, after the OCT image border line of the current needs correction of user is determined, then determine 3 reference mark describing controlling curve accordingly.As one embodiment of the invention, determine that the current optical coherence tomography OCT image border line of correction and 3 reference mark for describing controlling curve of needing of user comprise following S1011 and S1012:
S1011, user press left mouse button and current needs correct OCT image border line state for can not correcting state time, according to nearby principle select described current need correct OCT image border line.
It should be noted that, the coordinate forming the point of all edge lines of OCT image is all stored in memory storage with the form of data group.Can at the reference mark of all edge lines of initial phase initialization OCT image and controlling curve, namely, the all edge lines of OCT image preserved with the form of data group can be loaded, and, the current sequence number of the OCT image border line corrected that needs is set to an invalid value (such as,-1), the state at all reference mark for describing controlling curve is all set to irremovable state (characterizing with " false "), and all edge lines of OCT image are all set to can not correcting state (characterizing with " false ").
When user presses left mouse button, this event is converted into Message Transmission to system.As previously mentioned, for the OCT image border of initial phase, its state is can not correcting state.User press left mouse button and current needs correct OCT image border line state for can not correcting state time, the so-called OCT image border line selecting current needs correction according to nearby principle, can be specifically: the some Q(x of mouse pointer position when pressing left mouse button with user, y) be reference point, at a Q(x, y) there is the OCT image border line (hereinafter referred to as n-th bar of OCT image border line) that OCT image border line (hereinafter referred to as m bar of OCT image border line) that sequence number is m and sequence number are n near respectively, wherein, m bar OCT image border line has an X-direction coordinate and puts Q(x, y) the some M(x that X-direction coordinate is identical, y
m), n-th OCT image border line has an X-direction coordinate and some Q(x, y) the identical some N(x of X-direction coordinate, y
n), if y and y
mthe absolute value of difference is greater than y and y
nthe absolute value of difference, namely | y-y
m| >|y-y
n|, then selected n-th OCT image border line is as the current OCT image border line needing to correct.
S1012, during the OCT image border line corrected with selected current needs, mouse pointer is defined as intermediate control point in the position of two dimensional surface, with X-direction coordinate on the current OCT image border line needing to correct for the point at x-△ x place is defined as initial reference mark, finishing control point is defined as with the point that X-axis coordinate on the current OCT image border line needing to correct is x+ △ x place, wherein, x is the X-direction coordinate of intermediate control point on two dimensional surface (i.e. XoY plane), and △ x is preset value.
Owing to always correcting it within the specific limits the correction of OCT image border line, therefore, when user press left mouse button select current need correct OCT image border line after, can sliding mouse with in the line of OCT image border current need correct certain segment limit select.As previously mentioned, because the reference mark for describing controlling curve is determined according to mouse pointer position, therefore, determine user current need correct OCT image border line and for describe controlling curve 3 reference mark after, once user presses left mouse button sliding mouse pointer, then need to redefine 3 reference mark for describing controlling curve and intermediate control point, initial reference mark and finishing control point, concrete grammar is: by the position P of current mouse pointer in two dimensional surface (i.e. XoY plane)
c(x, y) is arranged to intermediate control point, according on n-th OCT image border line with P
c(x, y) has the some P of identical X-direction coordinate
n(x, y
n) its Y direction coordinate y
nwith P
cthe difference of (x, y) Y direction coordinate y, n-th OCT image border line finds initial reference mark and finishing control point.
Determine that the current OCT image border line corrected that needs of user is that to press left mouse button with user or press left mouse button and slide be trigger, namely user presses left mouse button or presses left mouse button and these events of sliding are passed to system after being all converted into message.Once user discharges left mouse button, then show that user confirms the OCT image border line that current needs correct, namely, determine user current need to correct OCT image border line and for describe controlling curve 3 reference mark after, the state also comprising the OCT image border line current needs corrected is set to recoverable state (with " true " sign).Because a reference mark, 3 for describing controlling curve is just determined, still can not determine which reference mark needs mobile, therefore, the state at 3 reference mark now remains can not correcting state (characterizing with " false ").
S102, when judging that the current state of OCT image border line needing to correct is recoverable state, when pressing left mouse button according to user, the reference mark of movement is determined to need in 3 reference mark in mouse pointer position.
As one embodiment of the invention, when judging that the current state of OCT image border line needing to correct is recoverable state, when pressing left mouse button according to user, mouse pointer position is determined to need the reference mark of movement to comprise following S1021 and S1022 in 3 reference mark:

S1022, needs the state at the reference mark of movement to be set to removable state by determining.
If calculate mouse pointer position when user presses left mouse button be in determine the reference mark needing movement selection range in, then this determined to need the state at reference mark of movement to be set to removable state (with " true " sign), the reference mark of needs movement can be moved to show that this is determined; Other reference mark is then set to irremovable state (characterizing with " false ").
The coordinate record of the mouse pointer position after slip, after user presses left mouse button sliding mouse pointer, is the reference mark coordinate after movement needing movement by S103.
As previously mentioned, the current state of the OCT image border line corrected that needs of user has been set to removable state, and, calculate mouse pointer position when user presses left mouse button be in determine the reference mark needing movement selection range in, then after user presses left mouse button sliding mouse pointer (this event is converted into Message Transmission equally to system), it is the reference mark coordinate after movement needing movement by the coordinate record of the mouse pointer position after slip, since then, the coordinate needing the reference mark of movement in 3 reference mark has been obtained.
