Problems solved by technology

[0003] The existing technology uses binocular cameras to obtain stereoscopic images. Under the trade-off between image resolution and object distance accuracy, the inevitable result is that the distance between binocular cameras is relatively large
However, due to the limitation of the position of the small UAV, the application of the binocular camera is very limited.
In the industry, large-scale drones are mostly used for related surveying and mapping, which is costly and not conducive to promotion

Abstract

The present invention provides a UAV-based stereoscopic imaging method and device, the method comprising: acquiring at least two target images of a target object from different positions by a UAV, wherein at least two of the target images are The target objects are at least partially overlapped; and a stereoscopic image of the target object is generated according to at least two of the target images. The two cameras in the binocular camera are replaced by a drone, and at least two target images of the target object are acquired from different positions, thereby obtaining a stereoscopic image of the target object, and the distance between the phase acquisition points is increased in a low-cost manner. The distance reduces the demand for imaging resolution and improves the accuracy of 3D reconstruction.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a stereoscopic imaging method and device based on an unmanned aerial vehicle. Background technique [0002] Stereoscopic vision is achieved through the difference in the position of the phase collection point. For example, there is a certain distance between the left and right eyes of a person, and there are subtle differences between the formed phases, so the distance of the object can be judged. The distance between the phase collection points is called the baseline. The farther the baseline is, the easier it is to obtain stereo vision, or the more obvious the stereo vision obtained. [0003] In the prior art, binocular cameras are used to obtain stereoscopic images. Under the trade-off between image resolution and object distance accuracy, the inevitable result is that the distance between the binocular cameras is relatively large. Due to the limitation of the position of the small UAV...
