Abstract

The invention discloses a method and system for stitching panoramas based on multiple cameras. The method for stitching panoramas based on multiple cameras is applied to unmanned aerial vehicles. The unmanned aerial vehicle includes a plurality of cameras for capturing different viewing angles, and Partial viewing angles of two adjacent cameras overlap, including the following steps: S1. Calibrate each camera separately to obtain the internal reference data and external reference data of each camera; S2. According to the internal reference data and external parameter data of each camera , project the image acquired by each camera to a UAV coordinate system, and the UAV coordinate system takes the vertical projection point of the UAV on the ground as the coordinate origin; S3. The images acquired by the camera are preprocessed; S4. According to the external parameter data of each camera, all the preprocessed images are matched by using the scale-invariant feature transformation feature to perform image stitching to obtain a panorama.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a method and system for stitching panoramas based on multiple cameras. Background technique [0002] UAV aerial photography technology is widely used in national ecological environment protection, mineral resources exploration, marine environment detection, land use investigation, water resources development, crops due to its advantages of high definition, large scale, small area and high potential Growth detection and yield estimation, agricultural operations, natural disaster detection and evaluation, urban planning and municipal management, forest pest protection and detection, public security, national defense, digital earth, and advertising photography have broad market demand. [0003] The existing UAV aerial photography technology mainly uses a single camera to obtain images. Although large-scale clear images can be obtained, the shooting area is limited. The compl...
