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] This embodiment provides a digital image acquisition system, and implements the present invention through basic necessary technical features to solve the problems raised in the technical background section of this application document.

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

[0041] The video acquisition module is used to shoot short videos through the camera to obtain panoramic videos;

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

[0043] The video frame decomposing module compares the images of each video frame with the two frames of the subsequent adjacent video frames, and cuts out the image that does not overlap with the subsequent video frame in the previous video frame to obtain the image bar of the panoramic video;

[0044] The image pre-stitching modu...

Embodiment 2

[0048] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, 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 decomposing module is to compare each video frame with the two frames of the next adjacent video frame, and compare the image of the previous video frame with 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 extracts the video frame to be processed and the next video frame of the video frame in time sequence as the contrast video frame of the video frame to be processed according to the sequence of time;

[0051] The image comparison module com...

Abstract

The invention discloses a digital image acquisition system, which comprises a video acquisition module for shooting a short video through a camera to obtain a panoramic video; a video decomposition module used for splitting the panoramic video to obtain all video frames of the panoramic video; a video frame decomposition module used for carrying out image comparison and cutting on each video frameand two frames of subsequent adjacent video frames to obtain an image strip of the panoramic video; an image pre-splicing module used for segmenting the image strips to obtain image blocks of a plurality of regions, and respectively extracting a characteristic value of each image block; and an image splicing module used for splicing the image blocks with the same characteristic value in each image strip, and covering the image strips on the corresponding image blocks to obtain a panoramic image. The shot video is separated according to each video frame, meanwhile, each video frame is cut to obtain a plurality of image strips with the same width, and then the image strips are screened and spliced 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 images 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, the captured frames are stitched together to obtain a long picture, which is the panoramic photo. In the existing technology for generating a panoramic image, a plurality of images are obtained by video, and the obtained images are spliced ​​to obtain a panoramic image. [0004] However, when the current panoramic images are spliced, certain errors occur due to inappropriate selection of splicing lines, resulting in incoherent images of the generated panoramic ima...
