Problems solved by technology

[0003] Although there are already some software that can realize the function of image stitching, such as Photoshop and Microsoft ICE, they generally require manual intervention, the operation is more complicated, and there are many restrictions on the stitched images
For medical images in surgical operations, real-time automatic splicing is often required, and these commercial software cannot be used

Abstract

The invention discloses a medical image stitching method which comprises the following steps of: A, inputting a multi-view video image sequence, and processing according to the time sequence; if the current frame is a key frame, sequentially executing steps B to H; otherwise, skipping over steps B to D, and directly performing subsequent steps E to H by use of the camera parameter calculated by use of the previous latest key frame; B, preprocessing multiple multi-view images of the current frame; C, performing characteristic extraction and matching of adjacent view images; D, estimating the camera parameter according to the extracted characteristic point and corresponding matching information; E, performing geometric correction on the image according to the obtained camera parameter; F, performing projection conversion and joint calculation according to the corrected result; G, performing further image stitching; and H, storing and displaying the final image. The method disclosed by the invention has the advantages of good image stitching effect and high efficiency.

Description

technical field [0001] The invention relates to computer graphics, in particular to a medical image splicing method. Background technique [0002] In surgical operations, microscopic imaging of high-resolution medical images allows doctors to clearly observe the location of surgery, greatly improving the accuracy of doctors' observation, positioning and operation during surgery, and ensuring smooth and safe operations. In addition to surgery, medical imaging microscopic imaging also plays a great role in the fields of medical pathology diagnosis, immune tissue detection, identification, judgment and analysis of biological tissues, such as cancer cell detection, cell biology detection and other occasions. However, in many traditional surgical operations, especially where the naked eye cannot directly observe and needs to be observed with the help of endoscopes and other equipment, due to the limitation of the depth of field and range of imaging equipment, doctors often can on...
