High-quality precise panoramic imaging system and method based on single lens reflex camera

Abstract

The invention belongs to the technical field of image processing, discloses a high-quality precise panoramic imaging system and method based on a single lens reflex camera, and provides a solution forintegrated development of multiple single lens reflex cameras. The system comprises a data processing end, a data conversion end and a data acquisition end. The data processing end adopts an embeddedprocessor and is provided with a program for controlling a plurality of camera shutter lines, a mode switching program, a picture downloading program and a panoramic splicing program. According to the invention, an integrated system of shutter line control and picture storage of a plurality of cameras is realized, and an image set collected at the same time can be processed into a panoramic image. A traditional multi-camera image acquisition and storage mode can be replaced, and the system has the advantages of no transmission distortion, time and labor saving, good panoramic effect, high efficiency, low cost and easiness in secondary development; moreover, the system gives accurate geometric information to the panoramic technology, accords with a photogrammetry model, meets high-level requirements of high-quality imaging and is applicable to various scenes.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a high-quality and precise panoramic imaging system and method based on a single-lens reflex camera. Background technique [0002] Traditional image acquisition devices mostly use a single lens to collect images. Moving the single-lens image acquisition device acquires images from different angles and stitches them together to obtain a panoramic image. This method is time-consuming, labor-intensive, and extremely unstable. With the advancement of technology, a panoramic image acquisition system composed of multiple lenses has emerged, which records images from various angles by surrounding the camera. However, the image stitching technology after image acquisition is difficult and the accuracy is poor. [0003] Panoramic cameras are divided into consumer-grade panoramic cameras and commercial-grade panoramic cameras. According to different needs, many panoram...

AI Technical Summary

Problems solved by technology

[0010] (1) In the prior art, panoramic cameras cannot achieve a balance between price and performance;

[0011] (2) Although consumer-grade cameras are low in cost and good in portability, a small amount of fisheye lenses will cause serious distortion of the captured pictures, and the clarity is relatively poor. The resolution of the images is not high, and secondary development is almost impossible;

[0012] (3) Although professional-grade cameras can solve the problems of image distortion, poor pixels, and low resolution to a certain extent, their promotion is limited due to their high price, and their secondary development capabilities are limited.

[0013] (4) Most of the functions are single panoramic browsing, which is a panoramic technology lacking accurate geometric information, and its application field is limited;
