Description
Technical Field
The present application relates to image processing technologies, and in particular, to an image processing method, system, and apparatus for eliminating laser delamination.
Background
Currently, during laser surgery, if the release time (pulse width) of the laser is very short, e.g., typically hundreds of microseconds (us), within the exposure time of one frame of image, then only a portion of the exposed lines will be "responded to" and the remaining exposed lines will still be normally exposed. For example, during holmium laser surgery, the very short release time (pulse width) of the holmium laser, typically hundreds of microseconds (us), for one frame of image exposure results in only a portion of the exposed lines being "responsive" and the remaining exposed lines still being normally exposed.
This causes delamination (a portion including the laser beam splitting region and another portion including the normal image region) in the finally formed image of one frame. The laser splitting area has high brightness and even overexposure, and dynamic 'bright light bars' can be presented at times when image frames are subsequently displayed, so that the operation visual field of a doctor in the laser operation process can be influenced, the judgment of the doctor is interfered, and the expected operation effect cannot be achieved.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with aspects such as the present application.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As described above, in laser surgery, if the release time (pulse width) of the laser within the exposure time of one frame image is often very short (only hundreds of us), only a part of the exposure lines will generate "response", and the rest of the exposure lines are still normally exposed, and a layer (referred to as laser layer) is generated in the finally formed frame image. The laser layering results in a frame image divided into two regions: laser splitting area and normal image area. The area size and the position of the laser splitting layer area are not fixed, but the brightness of the laser splitting layer area is higher and even overexposed. Taking holmium laser surgery as an example, delamination (denoted as holmium laser delamination) occurs in one frame of image acquired in holmium laser surgery. And the holmium laser delamination can cause one frame of image to be divided into two areas: holmium laser splitting area and normal image area. Fig. 1a shows an image in which a holmium laser splitting region is present by way of example, and fig. 1b shows an image in normal exposure by way of example.
For the above-mentioned images with laser stratification, such as holmium laser stratification, they may sometimes present dynamic "bright light bars" when displayed, which may cause visual discomfort to the physician performing the laser surgery, such as holmium laser surgery, etc., and may affect the operation visual field, interfere with the physician's judgment, and may fail to achieve the desired surgical effect. To solve such a technical problem, the present embodiment provides an image processing method for eliminating laser delamination such as holmium laser delamination, which can eliminate laser delamination existing in an image frame, as described below by way of example:
referring to fig. 2, fig. 2 is a flowchart of a method provided by an embodiment of the present application. The method is applied to image acquisition equipment in laser surgery. As one example, the image capture device may be an endoscopic imaging system in an endoscope, such as a set of lenses in an endoscope.
In the embodiment, the image acquisition device and the laser device applied to the laser surgery need to establish communication connection. When the imaging system is applied to holmium laser surgery, the endoscope imaging system is in communication connection with holmium laser equipment. The present embodiment does not specifically limit the communication connection manner, and includes but is not limited to a network port, a serial port, a can bus, bluetooth, and the like.
Based on the above description, as shown in fig. 2, the process may include the following steps:
In this embodiment, after detecting an external trigger (also referred to as a laser emission trigger), the laser device in the laser surgery transmits a laser excitation signal to the image capturing device through the communication connection, so that the image capturing device executes the process shown in fig. 2.
Specifically, the image capture device starts exposure signal detection after receiving the laser excitation signal. In this embodiment, an image capturing process of an image capturing device, such as a camera, includes the following two parts: the first part is the auto Exposure time (Exposure) and the second part is the Readout time. The readout time refers to the time when a sensor (sensor) in the image capturing device outputs an image after the image exposure is completed, and is generally about 20 to 30 ms. That is, the time for acquiring one frame of image (also called the image time) = exposure time + readout time. Fig. 3 shows an example of the plot time.
Based on the above description, in this embodiment, as described in step 201, in the case that the image capturing device detects an exposure completion event, it is determined whether the laser device needs to be controlled to emit a laser signal currently according to the current image output frame rate N of the image capturing device and the laser emission frequency M of the laser device. Here, the laser emission frequency M may be a frequency of laser excitation within one second(s), and if the laser emission frequency M is 15HZ, it means that the laser is excited 15 times within 1 s. In this embodiment, the laser emission frequency M of the laser device may be carried in the laser excitation signal by the laser device and sent to the image capturing device, or may be configured in advance in the image capturing device, and this embodiment is not particularly limited.
In the above description, the exposure complete event is, for example, the receipt of an exposure complete signal, a signal of Readout start, a Readout enable signal, or the like. Alternatively, in this embodiment, an exposure complete signal is generated at the end of each frame of automatic exposure, and the exposure complete signal is equal to a Readout start signal, also called a Readout enable signal.
As can be seen from step 201, in this embodiment, a laser device in laser surgery, such as a holmium laser device, does not directly perform laser emission even when the laser emission trigger is detected, but links an image capturing device, and determines whether the laser device needs to be controlled to emit a laser signal currently according to a current image output frame rate N and a laser emission frequency M of the laser device by the image capturing device. As to how to determine whether the laser device needs to be controlled to emit the laser signal currently according to the current image output frame rate N of the image acquisition device and the laser emission frequency M of the laser device, which will be described in the following by way of example, and will not be described herein again.
Step 202, on the premise that it is determined that the laser device needs to be controlled to emit the laser signal currently, the laser enable signal is sent through the communication connection established between the image acquisition device and the laser device, so that the laser device emits the laser signal after detecting the laser enable signal.
In this embodiment, a laser device in laser surgery, such as a holmium laser device, emits laser light after detecting the laser enable signal.
It should be noted that, this step 202 is executed on the premise that an exposure completion event is detected, based on this premise, the time for laser equipment in laser surgery, such as holmium laser equipment, to emit laser is within the above Readout time, and the laser is certainly not excited in the exposure process, so that the image exposure and the excitation of the laser are misaligned, and the generated current frame image does not generate a laser delamination phenomenon caused by the laser excitation.
Thus, the flow shown in fig. 2 is completed.
As can be seen from the flow shown in fig. 2, in this embodiment, communication is established between an image acquisition device in the laser surgery, such as an endoscope camera system, and a laser device, such as a holmium laser device, to cooperatively control the timing of laser excitation of the laser device, so as to control the time of laser emitted by the laser device in the laser surgery, such as the holmium laser device, to be within the Readout time, so as to avoid laser excitation by the laser device in the image exposure process, and finally, to avoid (or make misalignment between) image exposure and laser excitation, so as to ensure that the generated current frame image does not generate a laser delamination phenomenon caused by laser excitation, and further eliminate the laser delamination phenomenon in the acquired current frame image, eliminate visual obstruction of a doctor, and provide a good surgical impression.
How to determine whether the laser device needs to be controlled to emit the laser signal currently or not according to the current image output frame rate N of the image acquisition device and the laser emission frequency M of the laser device in the above step 201 is described as follows:
referring to fig. 4, fig. 4 is a flowchart of step 201 implementation provided in an embodiment of the present application. As shown in fig. 4, the process may include the following steps:
In this embodiment, the image frame-laser association relationship is used to indicate that the image capturing device needs to control the laser device to emit the laser signal n times every time m image frames are captured.
As an embodiment, there are many implementation ways to determine the image frame-laser association relationship according to the current image output frame rate N of the image acquisition device and the laser emission frequency M of the laser device, for example: calculating the maximum common factors of M and N, and dividing the numerator and the denominator in M/N by the maximum common factors respectively to obtain M/N, wherein M is greater than N, and N is greater than or equal to 1; and determining the image frame-laser association relation according to the m/n. If N is 30 and m is 20, N is 3 and m is 2, which means that the laser is fired 2 times every 3 frames, i.e. the image capturing device needs to generate the above laser enable signal for 2 frames of images in every 3 frames of images captured.
As an embodiment, there are many implementations for determining whether the laser device needs to be controlled to emit the laser signal currently according to the image frame-laser association relationship, such as: acquiring a first laser excitation signal sent by the laser equipment through the communication connection on the premise that the current image output frame rate of the image acquisition equipment is N and the laser emission frequency of the laser equipment is M; taking the image frame collected after receiving the first laser excitation signal as a first frame; and determining whether the laser equipment needs to be controlled to emit laser signals at present or not from the first frame according to the image frame-laser association relation.
Optionally, the determining, from the first frame, whether the laser device needs to be controlled to emit the laser signal at present according to the image frame-laser association relationship has a plurality of implementation manners, for example, detecting a frame number K of a target image frame corresponding to the exposure completion event; the frame number K is counted from the first frame; determining the current control period according to K; if K is larger than or equal to n, rounding K/n to obtain a calculation result p, and determining that the current control period is the (p + 1) th control period, wherein p is larger than or equal to 1; if K is smaller than n, determining that the current control period is the 1 st control period; and determining whether the laser equipment needs to be controlled to emit laser signals currently or not according to the image frame-laser association relation and the sequence of the current image frame in the current control period.
Here, it is determined whether the laser device needs to be controlled to emit the laser signal currently according to the image frame-laser association relationship and the sequence of the current image frame in the current control period, such as: if the laser is determined to be emitted or not according to the sequence in each control period, if the sequence number of the current image frame in the current control period is less than or equal to m, the laser device is determined to be required to be controlled to emit the laser signal, otherwise, the laser device is determined not to be required to be controlled to emit the laser signal currently. For example, the image frame-laser association relationship indicates that laser is excited every 3 frames for 2 times, and if the current image frame is the second frame image in the current control period, it may be determined that the laser device needs to be controlled to emit a laser signal currently based on the image frame-laser association relationship (indicating that laser is excited every 3 frames for 2 times); and if the current image frame is the 3 rd image in the current control period, because the previous two frames already determine that the laser device needs to be controlled to emit the laser signal, then based on the image frame-laser association relationship (indicating that the laser is excited for 2 times every 3 frames), it can be determined that the laser device does not need to be controlled to emit the laser signal currently. It should be noted that the present invention is by way of example only and is not limited thereto.
The flow shown in fig. 4 is completed.
Through the process shown in fig. 4, it is realized how to determine whether the laser device needs to be controlled to emit the laser signal currently according to the current image output frame rate N of the image acquisition device and the laser emission frequency M of the laser device.
It should be noted that, in the present embodiment, as described above, the laser apparatus in laser surgery detects the laser stop trigger after detecting the laser emission trigger. Once the laser stop trigger is detected, an excitation termination signal is sent to the image acquisition device through the connection. And the image acquisition equipment finishes the control of the laser emitted by the laser equipment on the premise of detecting the laser termination signal sent by the laser equipment through the communication connection.
The above is the method provided by the embodiments of the present application described in terms of an image capturing device such as an endoscopic imaging system standing in laser surgery, and the following is the method provided by the embodiments of the present application described in terms of a laser device such as a holmium laser device standing in laser surgery:

The method is applied to laser equipment in laser surgery, such as holmium laser equipment, and the laser equipment is in communication connection with image acquisition equipment used for acquiring images in the laser surgery, such as an endoscope imaging system.
As shown in fig. 5, the process may include the following steps:
In this embodiment, the sending of the laser enable signal by the image capturing device is determined based on the flow shown in fig. 2, for example, when it is determined that the laser device needs to be controlled to send the laser signal currently according to the current image output frame rate N of the image capturing device and the holmium laser emission frequency M of the laser device when the exposure completion event is detected, the laser enable signal is sent to the laser device through the communication connection, which is specifically shown in the flow shown in fig. 2.
When the laser equipment receives the laser enable signal, a laser signal is emitted once based on the laser enable signal.
As can be known from the above-described laser enable signal, in this embodiment, the image capturing device in the laser surgery, such as an endoscope camera system, and the like, establishes communication with the laser device, such as a holmium laser device, and the like, to control the timing of laser excitation of the laser device in the laser surgery in a linkage manner, so as to control the time of the laser emitted by the laser device in the laser surgery, such as the holmium laser device, to be within the Readout time, so as to avoid laser excitation by the laser device in the image exposure process, and finally, to avoid (or make a misalignment between) image exposure and laser excitation, so as to ensure that the generated current frame image does not generate a laser delamination phenomenon caused by laser excitation, thereby eliminating the laser delamination phenomenon in the acquired current frame image, eliminating a visual obstruction of a doctor, and providing a good surgical impression.
