Problems solved by technology

[0004] The feature point matching method is to calculate the slope based on all matching points. When the matching point error is large, there will be a large error between the complete slope of the matching map obtained and the actual need, resulting in a high probability of the final composite image. Ghosting, getting unclear stitched images

Abstract

The embodiment of the invention provides an ultrasonic wide-scene imaging method and device, and belongs to the field of image processing. The method comprises the steps that respective image featurepoints are extracted from the acquired two original images to be spliced; multiple matching opposite points which are correspondingly matched with the two original images are acquired based on the image feature points of each original image; the target matching opposite points are acquired from multiple matching opposite points; the overlapping area of the two original images is acquired based onthe target matching opposite points; the suture line is established based on the overlapping area; and the two original images are spliced into the ultrasonic wide-scene image through the suture line.With application of the method, the accurate matching opposite points can be acquired so that the acquired ultrasonic wide-scene image is enabled to have no ghosting and the definition of the ultrasonic wide-scene image can be enhanced.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an ultrasonic wide-view imaging method and device. Background technique [0002] Medical ultrasound imaging, which has the advantages of non-invasive and economical, is the preferred method for disease diagnosis and is widely used in clinical practice. But ultrasound imaging can only produce images with a small field of view, preventing doctors from seeing whole organs in a single ultrasound image. Using image stitching technology, the images being scanned are seamlessly stitched together to provide a wider field of view, which is beneficial to doctors' observation and diagnosis. In the wide-view imaging mode, as the probe scans forward along the detection area, a panoramic image is finally obtained by sequentially splicing the stitched image of the previous frame and the image obtained by the current scan. Compared with traditional ultrasound images, this image has a wi...
