As shown in fig. 1, the method includes:
s110, acquiring an image to be detected containing the diamond compact, and determining a target area in the image to be detected.
In this embodiment, the image to be measured refers to an X-ray image, for example, when cobalt removal depth measurement is required for the diamond compact, the diamond compact is photographed by an X-ray imaging device, and the photographed X-ray image is used as the image to be measured; when cobalt removal depth measurement is required to be carried out on a plurality of diamond composite sheets, taking X-ray images corresponding to the diamond composite sheets as images to be measured, and processing the images to be measured according to a unified processing process; the target area refers to an image to be measured and is divided into areas, the target area comprises a matrix area, the matrix area corresponds to a matrix part of the diamond composite sheet, the diamond area corresponds to an image area of the diamond composite sheet, the cobalt-removing layer area corresponds to a cobalt-removing layer of the diamond composite sheet, and the diamond peripheral area refers to an image area of the periphery of the diamond composite sheet in the image to be measured.
On the basis of the technical scheme, the obtaining the image to be detected containing the diamond compact comprises the following steps: and acquiring an original image containing the diamond compact, and adjusting target display parameters in the original image to obtain the image to be detected.
In a preferred embodiment scenario, to improve the accuracy of the cobalt-free depth measurement of the diamond compact, an original image containing the diamond compact, i.e., an image captured by some X-ray imaging devices, may be acquired first; the image quality of the original image is adjusted to obtain an image with higher quality, and the image is used as an image to be measured, for example, the target display parameters of the original image are adjusted, and the target display parameters include but are not limited to brightness, resolution, gray scale and contrast.
It will be appreciated that the same type of diamond, on the same X-ray apparatus, will take corresponding X-ray images with the same jig, and as the use time increases, the intensity of the X-ray tube will gradually decay, and the corresponding X-ray images will gradually darken. In addition, different X-ray imaging devices and different projects edited by operators have differences in X-ray image brightness of the same type of diamond compact, namely, the X-ray image brightness is darker than that of a standard image brightness, and the X-ray image brightness is possibly brighter. The brightness of the original image is different, and the original image is dark or bright, so that the brightness parameter in the target display parameters of the original image can be adjusted, and the adjusted image is used as the image to be measured.
Specifically, the integral gray scale characteristic of the original image can be determined, the integral gray scale characteristic value of the original image is adjusted according to the standard brightness value, and the adjusted image is used as the image to be measured; the gray characteristic value of the original measured image can be understood as a gray mean value, a gray variance, a gray entropy and the like of pixel points in the original image, the gray characteristic value of the original image is used for representing the brightness of the original image, the larger the gray characteristic value is, the brighter the corresponding brightness of the original image is, and the brightness of the original image is adjusted to obtain the image to be measured with moderate brightness. That is, the brightness value of the original image is increased or decreased to be close to the standard brightness value, the standard brightness value is one brightness value determined by a developer according to experience or experiment, when the brightness value of the image is the standard brightness value, the cobalt-free depth measurement accuracy of the diamond compact in the image is higher, and the scheme of the embodiment can be compatible with the original images with different brightness.

In this embodiment, exemplary, the straight lines on two sides of the outline of the diamond compact may be determined through the outline information, and the included angle between the two straight lines and the coordinate axis in the rectangular planar coordinate system may be determined as the above-mentioned placement angle, so that the placement angle may be adjusted to be consistent with the standard angle, the standard angle may be set to be 90 degrees with the included angle of the X-axis in the cartesian coordinate system, and the adjusted diamond compact is perpendicular to the X-axis, which is more beneficial to uniformly processing different diamond compact images and determining the corresponding cobalt-removing depth parameter.

On the basis of the technical scheme, before the cobalt-free boundary information between the diamond region and the cobalt-free layer region is determined, the method further comprises the following steps: and determining the gray level of a target area in the image to be detected, and adjusting the contrast between the diamond area and the cobalt-free layer area based on the gray level value of the target area.
In this embodiment, in order to better identify the cobalt-free boundary between the diamond region and the cobalt-free layer, the image to be measured may be enhanced, for example, according to the gray value based on each target region, the gray value of the cobalt-free layer region, the contrast of the cobalt-free layer, and the gray level of the background in the image to be measured, the contrast between the diamond region and the cobalt-free layer region is enhanced by some general contrast enhancement algorithms, so that the cobalt-free boundary is easier to be identified.
On the basis of the above technical solution, the determining cobalt-free boundary information between the diamond region and the cobalt-free layer region of the diamond compact in the target image includes: and acquiring gray scale information and contrast information of the cobalt-removing layer region, and determining the cobalt-removing boundary information based on the gray scale information of the matrix region, the gray scale information of the cobalt-removing layer region and the contrast information of the cobalt-removing layer.

And S140, determining a cobalt-removing measurement result corresponding to the diamond compact according to the matrix boundary information, the cobalt-removing boundary information and the contour information.
In this embodiment, after the matrix boundary information, the cobalt-free boundary information, and the contour information are obtained, the positions of the contour and the boundary line of each region in the image are obtained, and thus the cobalt-free measurement result of the diamond compact, for example, the cobalt-free measurement depth of the diamond, can be calculated.
