Embodiment 1

[0037] Such as Figure 1-Figure 6 As shown, this embodiment provides a method for automatic image stitching by adjusting the height of the X-ray detector, including the following steps:

[0038] S1. Calculating the three-dimensional coordinates of the joint points: the binocular camera 1 located in front of the detection position acquires the RGBD image of the human body on the detection position, and obtains the three-dimensional coordinates of the joint points of the human body through calculation. The three-dimensional coordinates of the joint points include the three-dimensional coordinates of the human shoulder joint points 2 and Three-dimensional coordinates of other joint points of several human bodies;

[0039] S2. Calculating the coordinate offset: subtracting the longitudinal coordinate value of the human shoulder joint point 2 from the preset longitudinal coordinate value of the shoulder joint point to obtain the coordinate offset;

[0040] S3. Initial position pos...

Embodiment 2

[0045] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 1.

[0046] In S1:

[0047] S1.1. Use the binocular camera 1 to shoot the scene at the detection position, collect the RGBD image information of the human body at the detection position, and process the RGBD image information through the processor to obtain an RGB image and a depth image. The depth image includes Image information and depth of field information;

[0048] S1.2. Calculate the positions of several human joint points in the depth image based on the deep learning model of human body joint point detection, and determine the joint point image coordinates of several human body joint points in the depth image;

[0049] S1.3. Calculate the three-dimensional coordinates of the joint points corresponding to the joint point image coordinates according to the joint point image coordinates, the depth of field information and the preset calibration parameters of the binocular camer...

Embodiment 3

[0053] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 1.

[0054] In S6:

[0055] S6.1. Determine alignment point 8: alignment point 8 is joint point 1 8.1 and joint point 2 8.2 in image A 10 and joint point 3 and joint point 4 in image B 11, joint point 1 8.1 and joint point 3 are the human body The same joint point, joint point 2 8.2 and joint point 4 are the same joint point of the human body;

[0056] S6.2. Alignment point 8 matching: joint point 1 8.1 is coincident with joint point 3, joint point 2 8.2 is coincident with joint point 4, and a rectangular overlapping area 9 is obtained;

[0057] S6.3. Perform image fusion on the rectangular overlapping area 9 to obtain a new A image 10. The A image 10 and the next B image 11 continue the splicing steps of the above S6.1 and S6.2 until all the images are completely relied on .

Abstract

The invention belongs to the technical field of digital image processing, and particularly relates to a method for automatically splicing images by adjusting the height of an x-ray detector, which comprises the following steps of: S1, calculating three-dimensional coordinates of joint points; S2, calculating coordinate offset; S3, carrying out initial position positioning; S4, determining coordinates of a moving reference point; S5, successively displacing and shooting an image; S6, splicing the images; according to the method for automatically splicing the images by adjusting the height of the x-ray detector provided by the invention, the position and the size of the overlapped part of the two images can be known by detecting the joint points of the human body, so that the matching splicing of the two images is realized, and the image splicing is easier.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and in particular relates to a method for automatically splicing images by adjusting the height of an X-ray detector. Background technique [0002] In the original image chain, the X light source, the center of the light beam, and the center of the flat panel detector are located on the same straight line, the position is relatively fixed and there is only one degree of freedom (moving up and down), and the conical beam emitted by the X light source passes through the light beam. A beam of specific shape and size is formed, which passes through the object to be photographed and is received by a flat panel detector located behind the object. [0003] For the needs of image diagnosis, the information of the entire human spine is usually required, and the flat panel detector can only obtain part of the information at a time. In order to present complete spine information on one ima...
