The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first", "second", "third", "fourth", and the like in the description and the claims of the present invention are used for distinguishing different objects, and are not used for describing a specific order. The terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
At present, when the two images are observed in a combined manner, a certain random angle deviation exists, namely, a certain random angle difference exists between an endoscope display image and an OCT display image, so that great inconvenience is brought to observation of a user, and the user can expend more energy on image correspondence. Based on the above, the embodiment of the invention discloses an OCT image display adjustment method, an OCT image display adjustment device, an electronic device and a storage medium, wherein a laser and a driving motor are associated, so that when the driving motor works, the laser is simultaneously turned on to form corresponding display mark information in a detection cavity; the display mark information assists the user to quickly identify and position the image.
Example one
Referring to fig. 1, fig. 1 is a schematic flow chart of an OCT image display adjustment method according to an embodiment of the present invention. The execution main body of the method described in the embodiment of the present invention is an execution main body composed of software or/and hardware, and the execution main body can receive related information in a wired or/and wireless manner and can send a certain instruction. Of course, it may also have certain processing and storage functions. The execution body may control a plurality of devices, such as a remote physical server or a cloud server and related software, or may be a local host or a server and related software for performing related operations on a device installed somewhere. In some scenarios, multiple storage devices may also be controlled, which may be co-located with the device or located in a different location. As shown in fig. 1, the method for OCT image display adjustment includes the following steps:
s101: sending a control signal to a driving motor to drive the OCT probe to rotate, and receiving a detection signal at the driving motor in the rotating process;
s102: acquiring an OCT image captured by an OCT imaging device;
s103: determining the working state of the laser according to the detection signal, and controlling the laser to emit a display mark to the surface of the detection cavity when the laser is in the working state;
s104: acquiring an endoscopic image within a detection lumen captured by an endoscopic device, the endoscopic image including display marker information.
When image acquisition is carried out, only endoscope images and OCT images are obtained, and both images do not have corresponding display marks for carrying out correspondence; the user can only carry out image correspondence through the detected shape and other features, and further observe the specific situation of the lesion appearing in the image. In the embodiment of the invention, the starting signal and the stopping signal of the driving motor are associated with the laser, so that the laser starts to work when the driving motor drives the OCT probe to work; the display marker is provided to make the user aware of different detection orientations.
When the specific laser coupling setting is carried out, laser emitted by the laser is coupled to the OCT probe, and then the laser is emitted to the detection cavity through the OCT probe; since the laser is coupled to the OCT probe, the position irradiated by the laser is the position where the OCT image is displayed when the OCT probe is detected; the display mark irradiated by the laser assists the user to realize rapid image correspondence.
FIG. 4 is a schematic diagram showing an original OCT image disclosed in the embodiment of the present invention, as shown in FIG. 4, the starting point and the ending point of the image display are fixed every time the OCT image is scanned, but the angle is random because the OCT probe penetrates into the working channel of the endoscope, that is, the starting point and the ending point of the driving motor are random; the final imaging result is that the endoscope image and the OCT image have certain display angle deviation. And the user cannot directly know where in the endoscopic image the OCT image is the sectional image. Fig. 3 is a schematic view of an endoscope image with display mark information according to an embodiment of the present invention, as shown in fig. 3, a ring mark in the figure is a concrete embodiment of a display mark, and when the ring mark is specifically arranged, the ring mark may also be in a semicircular ring or a dot or other form, and the main purpose of the ring mark is to mark a position; and the user is made to know the current detection position by displaying the circular scanning track.
Although the scheme can assist the user to know the specific display position, when observation is carried out, certain angle deviation exists, namely, when bubbles in a lumen are detected, the directions appearing in an OCT image and an endoscope image are different; therefore, when the user searches for the corresponding information again, certain inconvenience exists. As an alternative implementation, in the first aspect of the embodiment of the present invention, after the acquiring an endoscopic image inside a detection lumen captured by an endoscopic apparatus, the endoscopic image including display marker information, the method further includes:
s105: and performing rotation operation on the endoscope image or the OCT image according to the display mark information.

When the rotation operation is performed, there are two different ways, one is to provide a rotation interface for a user to enable the user to perform the rotation operation by himself, and the other is to perform the rotation operation directly on the OCT image or the endoscope image by recognizing an angle. More preferably, in the embodiment of the present invention, the OCT image is rotated, and since the angle between the endoscope image and the actual observation angle is more consistent, and the OCT image has a certain deviation from the actual display position due to the scanning display problem, the OCT image is rotated in the embodiment of the present invention, so that the user can better observe the OCT image.
As an alternative implementation manner, in a first aspect of the embodiments of the present invention, fig. 2 is a schematic flowchart of an image rotation operation disclosed in the embodiments of the present invention, and as shown in fig. 2, the performing a rotation operation on an endoscope image or an OCT image according to the display mark information includes:

s1052: and performing rotation operation on the endoscope image or the OCT image according to the angle information so as to enable the image display orientations of the endoscope image and the OCT image to be consistent.
The confirmation of the angle information can be realized in various ways: one is to provide an angle detection tool, such as a protractor, on the rotation operation page, to detect the angle by rotating the detection line of the protractor; then, when the corresponding angle information is determined, the equipment can automatically rotate the image; still another way is an image recognition way, when the orientation of the displayed mark point is detected, by constructing a rectangular coordinate system, then determining the position of the point in the rectangular coordinate system, and then calculating to obtain the corresponding angle information. When the angle is known, the apparatus can directly perform a rotation operation on the image to obtain an OCT image in accordance with the endoscope image display angle.
In embodiments of the present invention, the display marking information may take a number of different forms: the first is an annular display mark, since laser is coupled to the OCT probe, the laser is consistent with light emitted by the OCT probe, so that a laser irradiation region is also a detection region of the OCT probe, and a user can directly know a current detection position by displaying an annular scanning track; the second is to display the mark points, so that the detection position can be displayed on one hand, and the rotation start and stop points of the driving motor can be displayed on the other hand; thirdly, a mode of combining a ring shape and a mark point is adopted; as shown in fig. 3, two combined modes are actually adopted, the specific position of detection can be more clearly known to the user by displaying the circular scanning track, and the angular deviation of the image can be more clearly known to the user by displaying the position of the point.
