Embodiment 1

[0047] figure 1 A flowchart of a method for monitoring the operation process of endoscopic diagnosis and treatment provided by this embodiment is given.

[0048] Combine below figure 1 The specific implementation steps of the monitoring method of the endoscopic diagnosis and treatment operation process of this embodiment will be described in detail.

[0049] Such as figure 1 As shown, the monitoring method of the endoscopic diagnosis and treatment operation process of this embodiment includes:

[0050] Step S101: According to the historical continuous frame endoscopic images, detect the rectangular area of ​​the endoscopic field of view in each frame of the endoscopic image, intercept the rectangular area image and convert it into a gray-scale image to form a sample set;

[0051] In a specific implementation, the video signal of the endoscope contains m frames of images per second, which may not be processed by the computer in real time. In this embodiment, the resampling technique is ...

Embodiment approach

[0061] As another embodiment, the monitoring method of the endoscopic diagnosis and treatment operation process further includes:

[0062] Step S105: According to the real-time position of the endoscope, it is determined as the endoscope diagnosis and treatment operation time.

[0063] The advantage of the above technical solution is that, by standardizing the monitoring of the endoscopic operation process, the difference between operators is reduced, and the effective inspection time of the endoscopic operation can be fully guaranteed, thereby increasing the detection rate of the endoscopic lesions.

[0064] As a specific embodiment, when the endoscope is a gastroscope, the start state of the gastroscope diagnosis and treatment operation is set to outside. When the fully connected neural network first determines that the gastroscope is in the body, the operation duration timer is started, starting from 0 and counting every second. Until the fully connected neural network judges that...

Embodiment 2

[0077] figure 2 A structural schematic diagram of a monitoring system for an endoscopic diagnosis and treatment operation process provided in this embodiment is given.

[0078] Combine below figure 2 The specific structure of the monitoring system of the endoscopic diagnosis and treatment operation process of this embodiment will be described in detail.

[0079] Such as figure 2 As shown, the monitoring system of the endoscopic diagnosis and treatment operation process of this embodiment includes:

[0080] (1) The sample set construction module, which is used to detect the rectangular area of ​​the endoscopic field of view in each frame of the endoscopic image based on the historical continuous frame endoscopic image, intercept the rectangular area image and convert it into a gray image to form a sample set;

[0081] In a specific implementation, the video signal of the endoscope contains m frames of images per second, which may not be processed by the computer in real time. This em...

Abstract

The invention provides a monitoring method and system for an endoscope diagnosis and treatment operation process. The method comprises the steps of according to historical continuous frames of endoscopic images, detecting a rectangular area where an endoscopic visual field is located in each frame of endoscopic image, intercepting a rectangular area image and converting the rectangular area imageinto a grayscale image to form a sample set; labeling a label to which each sample image belongs; training a full-connection neural network by utilizing the sample set labeled with labels; for continuous k frames of grayscale images, if the grayscale images exceeding a preset proportion threshold belong to the body, judging that an endoscope enters the body, otherwise, judging that the endoscope is in vitro; receiving continuous k frames of endoscope images in real time from the start moment of endoscope diagnosis and treatment operation, inputting the images into the trained full-connection neural network, and outputting the position of the endoscope; if the endoscope does not enter the body and is still outside the body, y frames of endoscope images are moved backwards, wherein y is smaller than k; and taking the continuous k frames of endoscope images again and inputting into the trained full-connection neural network to judge the position of the endoscope again, wherein k is a positive integer larger than or equal to 3.

Description

Technical field [0001] The invention belongs to the field of endoscopic diagnosis and treatment image processing, and in particular relates to a monitoring method and system for an endoscopic diagnosis and treatment operation process. Background technique [0002] The statements in this section merely provide background information related to the present invention, and do not necessarily constitute prior art. [0003] Due to the large differences in operator behavior during digestive endoscopy, for example, insufficient inspection time, unstable inspection field, etc., the possibility of missing lesions is increased and the quality of endoscopy is reduced. However, the inventor found that traditional endoscope quality supervision methods consume a lot of labor and cost, and lack objective quantification methods, and cannot be carried out at all levels of endoscope centers. Summary of the invention [0004] In order to solve the above-mentioned problems, the first aspect of the pres...
