Mosaicking method and system of panoramic camera

Abstract

The invention discloses a mosaicking method and system of a panoramic camera. The method comprises steps as follows: acquiring images of multiple image sensors and caching the images in an internal memory of the panoramic camera; selecting two left and right adjacent images from the internal memory for mosaicking, and determining matched window areas with a window matching algorithm; calculating rotating and translation matrixes required by image mosaicking through matched pixel coordinates, and rotating and translating the two images; performing pixel fusion on the left and right images to realize image mosaicking. According to the provided mosaicking method and system of the panoramic camera, two left and right adjacent images are selected from the internal memory of the panoramic camerafor mosaicking, and the matched window areas are found from the two images with the window matching algorithm; by means of the matching method, the matched search area and the calculation times can be effectively reduced, higher calculation efficiency is realized, and real-time image mosaicking is convenient to realize.

Description

Technical field [0001] The invention belongs to the technical field of panoramic image splicing, and specifically is a panoramic camera splicing method and system. Background technique [0002] Panoramic cameras have been widely used in robotics, virtual reality and other fields. The main implementation scheme uses dedicated image sensors to obtain images and transfer the image data to smart devices such as computers or mobile phones. The smart device’s processor runs image stitching algorithms to achieve panoramic images. This architecture relies on the processing capabilities of smart devices, and the lack of real-time image stitching affects the smoothness of panoramic images; secondly, most existing panoramic cameras use two wide-angle cameras to achieve 360-degree image acquisition , The distortion of the image is large, which affects the imaging effect. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a splicing met...

[0002] Panoramic cameras have been widely used in robotics, virtual reality and other fields. The main implementation scheme uses a dedicated image sensor to obtain images and transmit the image data to smart devices such as computers or mobile phones. The processors of smart devices run image stitching algorithms to realize panoramic images. Such an architecture relies on the processing power of smart devices, and the real-time performance of image stitching is insufficient, which affects the fluency of panoramic images; secondly, most of the existing panoramic cameras use two wide-angle cameras to achieve 360-degree image acquisition , the distortion of the image is large, which affects the imaging effect
