Problems solved by technology

[0004] However, when the current panoramic images are spliced, some errors are generated due to the inappropriate selection of splicing lines, which leads to incoherent images of the generated panoramic images, and sometimes even image faults.

Embodiment 1

[0039] The present embodiment provides a digital image acquisition system, which realizes the present invention through basic necessary technical features, so as to solve the problems raised in the technical background part of this application document.

[0040] Specifically, as figure 1 As shown, an embodiment of the present invention provides a digital image acquisition system, including:

[0041] The video capture module captures short video through the camera to obtain panoramic video;

[0042] The video decomposition module splits the panoramic video of the video acquisition module to obtain all the video frames of the panoramic video;

[0043] The video frame decomposition module compares each video frame with two frames of adjacent video frames after it, and cuts the image that does not overlap with the next video frame in the previous video frame to obtain the image bar of the panoramic video;

[0044] The image pre-splicing module divides each image strip of the pan...

Embodiment 2

[0048] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable during operation and has better performance, but it is not limited to the one described in this example. implementation.

[0049] Specifically, in the above-mentioned Embodiment 1, the function of the video frame decomposition module is to perform image comparison between each video frame and two frames of adjacent video frames after it, and compare the video frame with the video frame that is not in the previous video frame and the next video frame. The overlapping images of the video frames are cropped to obtain the image strips of the panoramic video, which can be specifically divided into the following functional modules, including:

[0050] The video frame selection module sequentially extracts the video frame to be processed and the next video frame of the video frame in the time sequence according to the time sequence as the contrast video frame o...

Abstract

The invention discloses a digital image acquisition system, comprising: a video acquisition module, which shoots a short video through a camera to obtain a panoramic video; a video decomposition module, which splits the panoramic video to obtain all video frames of the panoramic video; the video frame The decomposition module compares each video frame with the two frames of the next adjacent video frame and cuts the image to obtain the image strip of the panoramic video; the image pre-splicing module divides the image strip to obtain multiple regions. image blocks, and extract the feature value of each image block respectively; the image splicing module splices the image blocks with the same feature value in each image strip, and covers the image strips on the corresponding image blocks to obtain a panoramic image. The invention separates the captured video according to each video frame, and at the same time, cuts each video frame to obtain a plurality of image strips with the same width, and then screens and stitches these image strips to obtain a new panoramic image.

Description

technical field [0001] The invention relates to the field of image acquisition equipment, in particular to a digital image acquisition system. Background technique [0002] When people go out to play, they usually take pictures as souvenirs. For some beautiful scenery, people also use the method of taking pictures to keep them, so that they can be viewed at any time in the future. [0003] At present, with the development of image technology, more and more cameras support the panoramic camera function. Specifically, each captured frame is stitched to obtain a long image, which is a panoramic photo. In the existing technology for generating a panoramic image, a panoramic image is obtained by obtaining a plurality of images by a video method, and splicing the obtained images. [0004] However, when the current panoramic images are spliced, certain errors are generated because the selection of the splicing lines is not very appropriate, so that the images of the generated pano...
