Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0022] The steps shown in the flowcharts of the drawings may be executed in, for example, a CPU, a dedicated image processing chip, or the like. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0023] In the existing panoramic video stitching method, it is necessary to perform post-splicing and fusion processing on the video captured by the panoramic camera through a mobile phone or a PC. The stitching in this way has poor real-time performance, h...

Abstract

The invention discloses a panoramic video real-time stitching method and device. The method includes the following steps: receiving multipath wide-angle video data shot by multiple image acquisition units; conducting synchronous processing on the multipath wide-angle video data; writing each path of synchronized wide-angle video data into a memory, and spreading the wide-angle video data to carry out distortion correction; and merging and stitching overlapped areas of the multipath wide-angle video data. Panoramic videos can be stitched in real time in a panoramic camera without being stitched and post-processed by a cell phone or a computer, the panoramic videos can be acquired and stitched immediately, the frame rate is consistent before stitching and after stitching, and the timeliness of panoramic video stitching is improved. Moreover, the stitching cost is low, no other hardware cost is needed, the operation is simplified, and the device is simple and easy to use.

Description

technical field [0001] The present application relates to image processing technology, in particular to a panoramic video real-time splicing method and device. Background technique [0002] With the development of visual image technology and video capture technology, video acquisition has developed from obtaining ordinary viewing angle video to wide-angle video, and further developed to panoramic video of 360 degrees in the horizontal direction and 360 degrees in the vertical direction. [0003] In order to obtain panoramic images, it is necessary to use a panoramic camera composed of two or more lenses to shoot images in multiple directions, and then stitch the images in multiple directions taken by two or more lenses into a panorama through a mobile phone or PC image. [0004] In the above-mentioned prior art, the method of capturing images by a panoramic camera and then performing post-splicing processing on a mobile phone or a PC to obtain a panoramic image has the disa...
