[0003] The existing methods for selecting multiple markers in the area to be scanned are all to randomly select multiple markers in the area to be scanned by the line scan camera scanning system, or to select multiple markers according to simple mathematical operations. It is reasonable to cause the subsequent scan image of the line scan camera to be unclear

Embodiment Construction
[0044] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0045] figure 1 It is a schematic flow chart of a method for intelligently selecting image focal length marker points according to the present invention, referring to figure 1 , a method for intelligently selecting image focal length marker points, comprising steps S1 to S3:
[0046] S1, acquiring image edge and color information of the target image. Among them, an area array camera can be used to acquire the image of the target object.
[0047] In this embodiment, the target object is a pathological slice. The color information includes shades of gray and, obviously, shades of colour.
[0048] Specifically, in this embodiment, the image edge of the target image is extracted by an image edge extraction algorithm; the grayscale image is obtained by grayscale processing of the target image, and the gray ...

The invention discloses an intelligent selection method of image focal length marking points, which includes acquiring image edge and color information of a target object image; selecting marking points according to the image edge and color information; deleting or adding marking points according to the degree of density of the marking points mark point. The invention also discloses a device and equipment for intelligently selecting an image focal length mark point. The present invention relates to the technical field of image processing, and relates to an intelligent selection method, device and equipment for image focal length marking points. By acquiring the image edge and color information of a target image, the marking points are selected according to the image edge and color information, and according to the density of the marking points Compared with the random selection of markers or the selection of markers by simple mathematical operations in the prior art, the selection of image focal length markers is more reasonable, avoiding the problem of unclear images scanned by subsequent line scan cameras.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method, device and equipment for intelligently selecting an image focal length marker point. Background technique [0002] The line scan camera collects at high speed. After each line is collected, it just moves to the next unit length and continues to collect the next line. In this way, a two-dimensional picture is assembled after a period of time, which is similar to the acquisition of an area array camera. to the picture. During the working process of the existing line scan camera scanning system, due to the unevenness of the surface of the target object, the carrier on which the target object (photographed object / scanned object) is placed is also inclined, which may cause the overall focus of the target object to be very large. Therefore, before scanning the target object, it is generally necessary to select multiple marker points in the area to be scanned for foc...
