Image freezing method, device, equipment and computer readable storage medium

Abstract

The invention discloses an image freezing method which comprises the following steps: receiving an image freezing instruction; screening the image with the highest definition value from the cached image as a current frame image, and determining a front preset frame image and a rear preset frame image corresponding to the current frame image; fusing the front preset frame image and the rear presetframe image with the current frame image to obtain a final frozen image; visibly, in the scheme, when the final frozen image is generated, not only is the image with the highest definition value obtained, but the front preset frame image and the rear preset frame image corresponding to the image with the highest definition value are also required to be acquired; the image with the highest definition value is fused with the front preset frame image and the rear preset frame image to generate the final frozen image, so that the frozen image is clearer, and the loss of useful information of the image is avoided. The invention further discloses an image freezing device, equipment and a computer readable storage medium; and the technical effects can be realized as well.

Description

technical field [0001] The present invention relates to the technical field of image freezing, and more specifically, to an image freezing method, device, equipment and computer-readable storage medium. Background technique [0002] At present, the medical endoscope system is inserted into the cavity tissue of the human body through the lens body to obtain images of the inner surface of the cavity. The image freezing function is the basic function of the clinical application of the endoscope. The current freezing methods include direct freezing, the clearest image selection freezing and so on. Freeze directly: After the system receives the freeze command, it directly freezes the image at the current moment and outputs it to devices such as monitors; choose to freeze the clearest image: After the system receives the freeze command, it selects from the video images within a period of time before and after the current moment, according to the clearest image High or low, select...

Problems solved by technology

[0003] However, in the above two methods, the direct freezing method cannot avoid motion, so the frozen image may be blurred. In order to obtain a clear image, the doctor needs to control the mirror body and the imaging object to be relatively static, but the imaging object (human body) has natural motion, which cannot be achieved. The purpose of complete relative stillness; the clearest image is selected to be frozen, and the clearest image is selected from a time series, which theoretically reduces the requirement for doctors to keep the mirror relatively still

However, the continuous frames in the video image are related, and the calculation method of the definition is also limited, and it cannot fully reflect the information contained in the image. Therefore, only one frame of image is selected as the frozen image, and some useful information may be lost. image information
