Obviously, the described embodiments are only exemplary embodiments of the present disclosure, rather than all embodiments.

In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "coupled" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances. In the present disclosure, the end close to the operator (e.g., doctor) is defined as the proximal end, near part, or rear end, and the end close to the surgical patient is defined as the distal end, far end, or front end, or front part. Those skilled in the art will appreciate that the embodiments of the present disclosure may be used for medical instruments or surgical robots, and may also be used for other non-medical devices.

[0024] Figure 1 FIG. 1 shows a structural block diagram of an endoscope visual image processing system 1000 according to some embodiments of the present disclosure. Figure 2 FIG. 1 is a block diagram showing a process of continuous parallel processing of multiple frames of images performed by an endoscope visual image processing system 1000 according to some embodiments of the present disclosure. Figure 1 As shown, the endoscope visual image processing system 1000 may include an endoscope 110 and a parallel processing circuit 120. The image acquisition circuit 120, the image transmission circuit 130, the image decoding circuit 140 and the image processing circuit 150.

[0025] The endoscope 110 may include an image capturing device 112, which is used to capture multiple frames of continuous images. For example, the image capturing device 112 may include a binocular camera. The parallel processing circuit 120 includes an image acquisition circuit 121, an image transmission circuit 122, an image decoding circuit 123, and an image processing circuit 124. The image acquisition circuit 121 is communicatively connected to the image capturing device 112, the image transmission circuit 122 is communicatively connected to the image acquisition circuit 121, the image decoding circuit 123 is communicatively connected to the image transmission circuit 122, and the image processing circuit 124 is communicatively connected to the image decoding circuit 123, for example, via a USB or bus connection. The image acquisition circuit 121, the image transmission circuit 122, the image decoding circuit 123, and the image processing circuit 124 perform continuous and parallel processing on multiple frames of continuous images. For each frame of image, the image acquisition circuit 121 acquires the image from the image shooting device 112, the image transmission circuit 122 uploads the image acquired by the image acquisition circuit 121 to the image decoding circuit 123, the image decoding circuit 123 decodes the received image, and the image processing circuit 124 performs image processing on the decoded image. To simplify the description, Figure 2 The process block diagram of continuously and parallelly processing 5 frames of images is shown in FIG. The above is only an example and is not limited thereto. Figure 2 As shown, the processing process for each frame of image may include multiple processing boxes, such as acquiring an image, uploading an image, decoding an image, and processing an image, wherein the image acquisition circuit 121 performs image acquisition, the image transmission circuit 122 performs image uploading, the image decoding circuit 123 performs image decoding, and the image processing circuit 124 performs image processing. It should be understood that at any processing box where the parallel processing circuit 120 processes the first frame of image (for example, at the image uploading processing box of the first frame of image), the parallel processing circuit 120 may start processing the second frame of image. Similarly, at any processing box where the parallel processing circuit 120 processes the second frame of image (for example, at the image uploading processing box of the second frame of image), the parallel processing circuit 120 may start processing the third frame of image, and so on, to achieve continuous parallel processing of multiple frames of continuous images. By processing multiple frames of continuous images in parallel through the parallel processing circuit 120 (e.g., the image acquisition circuit 121, the image transmission circuit 122, the image decoding circuit 123, and the image processing circuit 124), the image processing time can be shortened, and an endoscopic visual image processing system with low visual delay can be realized. It should be understood that the image capture device 112 can compress the captured multiple frames of continuous images, which can facilitate the image acquisition circuit 121 to acquire images from the image capture device 112 and upload them to the image decoding circuit 123 through the image transmission circuit 122, so as to save image transmission time.

[0026] In some embodiments, Figure 1As shown, the parallel processing circuit 120 may further include a display processing circuit 125, and the endoscope visual image processing system 1000 may further include a display device. The display processing circuit 125 is communicatively connected to the image processing circuit 124, and the display device is communicatively connected to the display processing circuit 125. The display processing circuit 125 is used to display the image processed on the display device for each frame of image. For example, the display device may include a stereo display 130 or a two-dimensional (2D) display 140. The display processing circuit 125 may send display data to the display device to display the image processed on the display device, such as a video captured by an endoscope. By displaying the image on the display device, it is convenient for the operator to observe the shooting field of view in real time. As Figure 2 As shown, the processing of each frame of image may also include display processing, and the display processing circuit 125 performs the display processing.

[0027] In some embodiments, Figure 2 As shown, the multiple frames of continuous images include N frames of continuous images, and the parallel processing circuit 120 is used to perform continuous parallel processing on the N frames of continuous images, where N is a positive integer greater than or equal to 2. For example, when N is equal to 5, the parallel processing circuit 120 can simultaneously perform parallel processing on 5 frames of images. In this way, the throughput of the parallel processing circuit 120 can be increased and the delay in the image processing process can be reduced. It should be understood that the above is only an example, and N can also be 2, 3, 4 or other positive integers. In some embodiments, the parallel processing circuit 120 may also include an adjustment circuit 126, and the adjustment circuit 126 adjusts the number of image frames N processed in parallel based on the complexity of the image processing performed on each frame of the image. The above is only an example and is not limited to this.

[0028] Existing endoscope visual image processing systems are expensive for image processing, have large visual delays, and have poor design flexibility. The endoscope visual image processing system 1000 disclosed herein realizes parallel processing of images by designing multiple circuits capable of parallel processing (e.g., image acquisition circuit 121, image transmission circuit 122, image decoding circuit 123, image processing circuit 124, display processing circuit 125), thereby saving system costs, shortening the delay of visual image processing, and improving the flexibility of system design.

[0029] In some embodiments, image processing may include various image processing techniques, such as noise reduction processing, contrast processing, brightness processing, saturation processing, sharpening processing, and distortion correction processing. It should be understood that one or more of the image processing steps can be selected based on the actual image processing operation requirements and the algorithms or requirements involved in the image processing process. For example, for occasions with low image processing operation requirements, the image processing steps can be reduced, and for occasions with high image processing operation requirements, the image processing steps can be increased to increase the adaptability of the endoscope visual image processing system.

[0030] In some embodiments, the processing time of each frame of image by the parallel processing circuit 120 may be less than 90 ms. In this way, the performance requirements in actual use, such as the visual delay requirements of clinical operation of endoscopic surgery system, can be met.

[0031] In some embodiments, the image capture device may include a left-eye camera and a right-eye camera, and the multiple frames of continuous images may include multiple frames of left-eye continuous images and multiple frames of right-eye continuous images. The parallel processing circuit 120 may perform independent continuous parallel processing on the multiple frames of left-eye continuous images and the multiple frames of right-eye continuous images in parallel. Processing the multiple frames of left-eye continuous images and the multiple frames of right-eye continuous images in parallel can further improve the image processing capability of the parallel processing circuit 120 and reduce processing delays.

[0032] In some embodiments, the display processing circuit 125 also synchronizes the image-processed left-eye continuous images and right-eye continuous images, and displays them on the stereoscopic display 130. It should be understood that the image acquisition circuit 121, the image transmission circuit 122, the image decoding circuit 123 and the image processing circuit 124 can continuously and parallelly process multiple frames of left-eye continuous images, and at the same time, can continuously and parallelly process multiple frames of right-eye continuous images. After the multiple frames of left-eye continuous images and the multiple frames of right-eye continuous images are processed respectively, the display processing circuit 125 can synchronize the image-processed left-eye continuous images and right-eye continuous images using appropriate technology, such as "Triple Buffering" technology, and display them on the stereoscopic display 130. In some embodiments, the display processing circuit 125 also displays the image-processed left-eye continuous images or right-eye continuous images on the 2D display 140. For example, the display processing circuit 125 can select the image-processed left-eye continuous images to be displayed on the 2D display 140, or the display processing circuit 125 can also select the image-processed right-eye continuous images to be displayed on the 2D display 140. It should be understood that the display processing circuit 125 can display the image after image processing on the stereoscopic display 130 and the 2D display 140 at the same time.

[0033] Those skilled in the art can understand that various circuits involved in the present disclosure, such as image acquisition circuit, image transmission circuit, image decoding circuit, image processing circuit, display processing circuit, adjustment circuit, etc., can be implemented by various suitable hardware including, for example, dedicated integrated circuits, general integrated circuits, etc. The specific hardware structure used to implement the image acquisition circuit, image transmission circuit, image decoding circuit, image processing circuit, display processing circuit, and adjustment circuit can be implemented by various technologies, such as analog circuits, digital circuits, configurable circuits, or dedicated circuits, etc.

Figure 3 As shown, the present disclosure also provides a surgical robot 100, comprising at least one mechanical arm 10 and an endoscopic visual image processing system 1000 in any embodiment of the present disclosure. The endoscope 110 of the endoscopic visual image processing system 1000 is detachably disposed at the end of one of the at least one mechanical arm 10.

[0035] In some embodiments, at least one robot arm 10 may include multiple robot arms. Each robot arm may include a multi-section arm body and multiple joints connecting the multi-section arm body, and the multi-section arm body includes a terminal arm. The endoscope 110 is detachably arranged on the terminal arm of one of the robot arms, and one or more surgical instruments may be arranged on the terminal arms of the remaining one or more robot arms. In some embodiments, the surgical robot 100 may include a robot arm 10. The robot arm 10 may include a multi-section arm body and multiple joints connecting the multi-section arm body, the multi-section arm body includes a terminal arm, and the terminal arm includes multiple tool mounting positions, the endoscope 110 is detachably arranged on one of the tool mounting positions, and one or more surgical instruments may be arranged on the remaining one or more tool mounting positions.

[0036] The endoscope 110 may include an endoscope arm 111 and an image capturing device 112, such as a binocular camera, disposed at the distal end of the endoscope arm 111. During operation, the surgical robot 100 controls at least one mechanical arm 10 to move so that the end of at least one mechanical arm 10 moves to an appropriate posture (e.g., a target posture). The operator may control the movement of the endoscope arm 111 so that the image capturing device 112 of the endoscope 110 is located at the optimal shooting field of view, so that the image capturing device 112 can capture the scene in the surgical field of view in real time. The operator may perform surgical operations such as cutting, clamping, electrocoagulation, electrocuting, suturing, etc., based on the captured images, using surgical instruments. By processing multiple frames of continuous images (e.g., video streams) in parallel through a parallel processing circuit 120 (e.g., an image acquisition circuit 121, an image transmission circuit 122, an image decoding circuit 123, an image processing circuit 124, and a display processing circuit 125), the image processing time may be shortened, the visual delay during the image processing process may be reduced, and the surgical quality may be improved.
