Problems solved by technology

However, each image can still only show one side of the object, and cannot show the whole picture of the object on one image.
Although the appearance of the object can be completely recorded by using the camera to surround the camera, the video stream captured by the camera not only has a huge amount of data, but also requires a specific player to play, resulting in poor applicability

Embodiment 1

[0031] The generation method of the panorama image of the present embodiment, comprises the following steps:

[0032] ①Collect photo sequence: take the photos of the real scene taken as image samples, and grayscale the image samples;

[0033] ②Image stitching:

[0034] The first step, image smoothing: smoothing the grayscale image samples, the formula for image sample smoothing is:

[0035]

[0036] where f(i,j) is the input image, h(i,j) is the smoothing convolution filter, and g(i,j) is the output image;

[0037] The second step is the extraction of circular feature templates: the original image is segmented with double thresholds on the two-dimensional histogram. After marking and screening, the matching templates required in the matching process are quickly extracted, and the center of the selected feature block is The position is used as the center pixel of the ring template, thereby establishing the ring template;

[0038] The third step, rough matching: it is used...

Abstract

The invention provides a panoramic image generation method comprising the steps of photo sequence collection, image splicing and image stitching. The step of image splicing comprises the substeps of image smoothing, annular characteristic template extracting, rough matching and fine matching. Image stitching is performed after image splicing is finished. The panoramic image generation method has the advantages that on the basis of fully analyzing the characteristics of product surface images, the dual threshold value conversion method and the gradient histogram equalization algorithm are combined to reinforce the images and at the same time image segmentation is performed, so that the processing speed is increased; the method is not sensitive to the influence of external light and is great in environmental adaptability; the speed is much higher than the speed of the method that only Euclidean distance is used for judgment.

Description

technical field [0001] The invention relates to a method for generating panoramic images. Background technique [0002] At present, using an electronic device with an image acquisition unit, such as a camera, one image taken can only record one side of the object. In order to record the appearance of the object (such as exhibits, sculptures, etc.) more completely, it is necessary to take multiple images of the same object. However, each image can still only show one side of the object, and cannot show the whole picture of the object on one image. Although the appearance of the object can be completely recorded by using the camera to surround the camera, the video stream captured by the camera not only has a huge amount of data, but also requires a specific player to play, resulting in poor applicability. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for generating panoramic ima...
