[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] At present, in the prior art, the connection line between the image acquisition instrument and the image acquisition card of the acquisition host is relatively long, which is likely to cause attenuation of the image acquisition quality. At the same time, engineers need to continuously maintain the relevant parameters of the acquisition card or replace the connection line for continuous maintenance, which will cause inconvenience to users and waste of human resources. In addition, the existing image acquisition docking mode is one-to-one docking, where one host is bound to one instrument, and it is impossible to dock multiple instruments simultaneously, so it is impossible to monitor the acquisition status of multiple instruments at the same time, and the department management personnel cannot monitor the image acquisition situation in the department in real time. Finally, the integrated software system cannot freely replace the acquisition signal source. If a certain acquisition host has a problem, other acquisition hosts cannot freely switch, and the acquisition host must be replaced again to continue working, which has a relatively significant impact on subsequent work.

[0034] Based on this, a distributed image acquisition system, method, electronic device and medium provided by an embodiment of the present invention can improve the image acquisition quality and stability.

[0035] For the convenience of understanding this embodiment, first, a distributed image acquisition system disclosed in an embodiment of the present invention will be introduced in detail. Refer to Figure 1 As shown in the structural schematic diagram of a distributed image acquisition system, it is shown that the system mainly includes: a front-end acquisition device 10, a network switch 20, an acquisition management monitoring center 30, and an acquisition host 40; among them, the acquisition host 40 includes image acquisition software for processing the acquired video signal.

[0036] The front-end acquisition device 10 is connected to the acquisition host 40 through the network switch 20. Each front-end acquisition device 10 corresponds to an image acquisition instrument (such as an ultrasound device or an endoscope device, etc., an image acquisition device) and an acquisition host 40. The front-end acquisition device 10 is used to acquire the video signal of the image acquisition instrument and upload the video signal to the acquisition host 40; the acquisition management monitoring center is connected to the 30 front-end acquisition devices 10 and the acquisition host 40 for monitoring the running state of the system.

[0037] In the above-mentioned distributed image acquisition system provided by the embodiment of the present invention, the front-end acquisition device is directly installed together with the image acquisition instrument. By placing the acquisition device in the front, the connection of a long video acquisition dedicated line is avoided, effectively reducing the attenuation of the acquired image quality and improving the image acquisition quality and stability; at the same time, the above system can monitor the front-end acquisition device in real time through the acquisition management monitoring center, and implement the monitoring of the working state of the front-end acquisition device, so as to intuitively understand the running status of the system.

[0038] In one implementation, refer to Figure 2As shown in the figure, the front-end acquisition device includes: an image acquisition unit, an image compression unit, and a monitoring probe unit; the image acquisition unit is used to receive the video signal collected by the image acquisition instrument and cache the video signal; the image compression unit is used to compress the received video signal; the monitoring probe unit is used to detect the operating status of the image acquisition unit and the image compression unit, and monitor whether the operation of the image acquisition unit and the image compression unit is normal.

[0039] In a specific implementation, the front-end acquisition device includes: an image acquisition unit, an image compression unit, and a monitoring probe unit. The image acquisition unit can receive video signal input and complete the caching of the internal video stream; the image compression unit can compress the received video stream, and this unit supports multiple compression methods, such as: the video stream with the common format H264 and 1080P resolution. Through image compression, the amount of data transmitted can be effectively reduced; the monitoring probe unit can detect the operating status of the image acquisition unit and the image compression unit, and mainly monitor whether each main working unit is normal.

[0040] Considering that the traditional acquisition card is installed in the report post-processing workstation, and one endoscope / ultrasound device is bound to one report post-processing workstation. When the host of one report post-processing workstation is damaged, the normal business process will be affected. It can only resume normal business use after replacing the host of the report workstation and reinstalling the relevant acquisition card software driver, software product and performing device online connection.

[0041] Based on this, in the above system provided by the embodiments of the present invention, one report post-processing workstation corresponds to multiple front-end acquisition devices, and the front-end acquisition devices switch different report post-processing workstations under the control of the acquisition management monitoring center.

[0042] See Figure 3 As shown in the figure, after the acquisition device is placed in the front-end, the acquisition card is separated from the report post-processing workstation. The front-end acquisition device can freely switch between each report workstation under the action of the acquisition management monitoring center. The endoscope / ultrasound device and the report post-processing workstation realize a many-to-many connection. If the host of one report post-processing workstation fails, the video source of the original host can be taken over on another host, and the doctor can switch from the faulty host to the normal host within seconds and immediately perform the normal business process, improving work efficiency. Specifically, see Figure 4 As shown in the figure, in this embodiment, one report post-processing workstation can be connected to multiple videos, and can switch among multiple videos to support the signal acquisition of multiple endoscopes / ultrasound devices.

[0043] In one implementation, see Figure 5As shown, the acquisition host receives the input information of the acquired video signal through the Ethernet port. Specifically, the acquisition host receives the input information of the acquired image through a standard Ethernet port.

[0044] See Figure 6 As shown, the image acquisition software includes: a video acquisition unit, a video decompression unit, a video source control unit, a display control unit, an image conversion unit, and an image capture unit; among them, the video acquisition unit is used to receive the input signal of the video stream; the video decompression unit is used to decompress the video stream; the video source control unit is used to switch the input of multiple video streams; the display control unit is used to control the display of the video stream; the image capture unit is used to capture the image frames in the video stream; the image conversion unit is used to perform image format conversion on the captured images.

[0045] Considering that in the existing direct docking mode of acquisition cards, there are a variety of acquisition cards, and there is no standard way to provide the acquisition quality for docking. It is necessary to adapt to various acquisition cards, and the image acquisition quality cannot be guaranteed. Based on this, in the embodiments of the present invention, based on the balance between cost and quality, the front-end acquisition device uses a standard acquisition card. The front-end acquisition device provides standard interfaces (video saving function, image capture function) for the acquisition host to call, ensuring the image quality of the acquired images and making the high resolution and high definition of the acquired images consistent.

[0046] For the convenience of understanding, the embodiments of the present invention also provide a working process of the image acquisition software. See Figure 7 As shown, the video acquisition unit receives the video stream input signal (in formats such as H264), the video decompression unit decompresses the video stream, the video source control unit can select to switch the input of multiple video streams, and the image acquisition software can select multiple video stream input sources. If it is necessary to switch the video source, the video source is changed, and the video acquisition unit receives the video stream input signal again. If there is no need to switch, the display of the video stream is controlled through the display control unit, and the image is displayed on the screen area of the acquisition host at an appropriate resolution. When it is necessary to capture an image, the image capture unit can freeze and capture the image frames in the current video stream as needed, and finally use the image conversion unit to perform image format conversion (such as BMP, JPG, PNG, etc.) to complete the image capture and saving function.

[0047] For the business requirements of the endoscopy / ultrasound department, during the patient examination process, it is necessary to capture and save the observed content, which is then reflected in the report and finally handed over to the patient. Therefore, in this embodiment, image capture is required through the image capture unit during image acquisition. The specific image capture process requires interaction between the front-end acquisition device and the report post-processing workstation: a) The report post-processing workstation starts to capture the screen; b) The report post-processing workstation sends a message to the front-end acquisition device; c) The front-end acquisition device locates in the current video stream; d) Image capture is performed according to imaging parameters (resolution, brightness, etc.); e) The capture result is returned to the report post-processing workstation. The calculation of the image capture method provided in the embodiment of the present invention is distributed in the front-end acquisition device, greatly reducing the local computing power requirements for the report post-processing workstation, thereby reducing the hardware requirements for the report post-processing workstation.

[0048] In one implementation, the acquisition management and monitoring center can manage each front-end acquisition device and centrally display the monitoring results. Since the video information generated by the devices is aggregated to the acquisition control and management server through the front-end acquisition device. To improve the stability of the system, the acquisition monitoring and management center in this embodiment can adopt an HA high-availability design to prevent single-node failures. See Figure 8 As shown, the acquisition management and monitoring center includes: a front-end device probe status receiving unit, a front-end device status management unit, and a front-end device status obtaining unit; the front-end device probe status receiving unit is connected to the monitoring probe unit of the front-end acquisition device for obtaining the information of the monitoring probe unit; the front-end device status management unit is used to monitor and manage the working status of the front-end acquisition device. If an abnormality of the front-end acquisition device is detected, it displays the abnormal working status; it is also used to send a restart working unit instruction to the front-end acquisition device; the front-end device status obtaining unit is used to obtain the working status of the front-end acquisition device.

[0049] In specific implementation, the front-end device probe status receiving unit is interconnected with the monitoring probe units of each front-end acquisition device, and can obtain the information of the monitoring probe unit in real time. If the signal of the monitoring probe unit is not received, it can be determined that the front-end acquisition device has been powered off.

[0050] The front-end device status management unit can uniformly manage the status of the front-end acquisition device as on or off. Its working principle is as follows: The image acquisition unit and the image compression unit of the front-end acquisition device generate work logs at regular intervals. The monitoring probe unit polls the work logs of the image acquisition unit and the image compression unit. If an abnormality is found, the abnormal working status can be displayed. At the same time, an instruction to restart the working unit can be sent to the front-end acquisition device to restart its abnormal working unit. Specifically, in this embodiment, heartbeat monitoring technology can be used to monitor and manage the status of the front-end acquisition device. The monitoring probe unit regularly sends https messages to the image acquisition unit and the image compression unit. If a message is returned, it indicates that the service status is normal. If no message is returned, it indicates that the service is abnormal. When the service is abnormal, the front-end device status management unit can send an instruction to restart the working unit to the front-end acquisition device to restart its abnormal working unit.

[0051] The front-end device status acquisition unit can acquire the status of the front-end acquisition device. In this embodiment, two forms of acquisition methods can be provided: one is the status interface of a single front-end acquisition device, provided in the form of an API; the other is the status integrated display form integrated in the page, provided in the form of page integration.

[0052] The above system provided by the embodiment of the present invention improves the traditional image acquisition method from the acquisition card mode on the host to the front-end acquisition device mode connected to the image acquisition instrument, cancels the long video cable required by the original mode, thereby improving the quality of the acquired image and reducing the failure rate of the host acquisition mode; through the distributed deployment method, each acquisition host can be conveniently switched among the front-end acquisition devices. In the extreme case of host failure, different hosts can be conveniently selected for work, effectively improving the overall stability of the system; through the monitoring service at the central end, a very intuitive understanding of the overall operation of the system can be obtained, so that a clear understanding of the system operation can be achieved; an image acquisition software is set in the acquisition host, and the image acquisition software realizes connection with each front-end acquisition device through the network, and finally realizes free switching of the front-end acquisition device and performs image processing on the acquired video stream, thereby obtaining a better-quality acquired image.

[0053] For the distributed image acquisition system provided in the foregoing embodiment, the embodiment of the present invention also provides a distributed image acquisition method. Refer to Figure 9 the flowchart of a distributed image acquisition method shown in

[0055] Step S902: The acquisition host decompresses, intercepts images, and converts the format of the video signal to obtain an acquired image.

[0056] In the above-mentioned distributed image acquisition method provided by the embodiments of the present invention, the front-end acquisition device is directly installed together with the image acquisition instrument. By placing the acquisition device in the front, the connection of a long video acquisition dedicated line is avoided, effectively reducing the attenuation of the acquired image quality and improving the image acquisition quality and stability.
