AI Technical Summary

Technical Problem

In narrow spatial scenarios, existing technologies struggle to obtain highly accurate panoramic images through feature point matching of image acquisition devices, especially when there is significant parallax between adjacent cameras and environmental noise, resulting in low accuracy of panoramic images.

Method used

By setting a calibration object on the target object, the relative pose information between the image acquisition device and the target object is obtained using the calibration result of the calibration object, and the images are stitched together. This avoids reliance on feature point matching and achieves more stable and accurate panoramic image acquisition.

Benefits of technology

It improves the stability and accuracy of panoramic images, especially under the influence of environmental noise and parallax, and can obtain more accurate panoramic images, making it suitable for panoramic video generation in dynamic scenes.

Abstract

The application discloses a method, device, system and equipment for obtaining panoramic images and a storage medium, and relates to the technical field of image processing. The method comprises the following steps: splicing a plurality of first images by first calibration results obtained from calibration objects in the plurality of first images to obtain a first panoramic image of a target scene; and splicing a plurality of second images by second calibration results obtained from calibration objects in the plurality of second images to obtain a second panoramic image of the target scene. The plurality of first images and the plurality of second images are obtained by a plurality of image acquisition devices with different field of view ranges in different time periods, and the plurality of image acquisition devices acquire images of a target scene including a target object. The position of the target object in the second panoramic image is different from that in the first panoramic image. The panoramic images are obtained by splicing dynamic calibration results, and the splicing process does not depend on feature point matching in the images, and is free from the influence of noise such as smoke and light on the feature points in the images, so that the stability of the obtained panoramic images is better, and the accuracy is higher.
