Problems solved by technology

However, it takes a lot of computing resources and time to fully scan the image, so the speed of image stitching is often not as fast as the low-latency requirement for real-time viewing by users

Embodiment Construction

[0024] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0025] figure 1 A block diagram of an electronic device 100 according to an embodiment of the invention is shown.

[0026] Please refer to figure 1 , the electronic device 100 includes a bendable base 110 , a plurality of camera modules 102 - 1 - 102 -N (N is a positive integer greater than 1), a sensing module 104 and a processing module 106 . The base 110 may have a bendable mechanism (such as a pivot), and / or be made of any foldable material such as plastic or resin. The camera modules 102 - 1 - 102 -N may be Charge-Coupled Device (CCD) sensors, Complementary Metal-Oxide-Semiconductor (CMOS) sensors or other camera devices. The sensing module 104 can be an accelerometer, a gyroscope, a distance sensor, a resistance / capacitance sensing element, or any sensor capable of detecting changes in the bending angle of the base 11...

Abstract

An image stitching method and an electronic device applied thereto. The electronic device includes a bendable base, a plurality of camera modules, a sensing module and a processing module. The camera modules are installed on the base, and can capture multiple images corresponding to different fields of view. The sensing module is coupled to the base, and is used for detecting physical bending information of the base. The processing module is coupled to the camera module and the sensing module, and is used for estimating the bending angle of the base using physical bending information, and obtaining overlapping information between multiple images according to the bending angle, and stitching the images based on the overlapping information, to generate stitched images.

Description

technical field [0001] The invention relates to an image stitching method and an electronic device using the method. Background technique [0002] With the advancement of miniature camera technology, more and more products can simultaneously use multiple cameras to generate images with a wider field of view, such as panoramic shooting, surveillance systems, around view monitoring systems (Around View Monitoring, AVM) and so on. Generally speaking, such products can increase the field of view of the output image by combining images captured by multiple lenses, and this process usually relies on image stitching algorithms to complete. [0003] The image stitching algorithm mainly cuts and collages multiple images corresponding to different fields of view to stitch them into a wide field of view image. Currently, image stitching algorithms can be divided into two types: real-time stitching and offline stitching. However, the offline stitching algorithm has certain limitations...
