Problems solved by technology

In addition, the light field depth calculation algorithm is also severely restricted by the large amount of light field data and calculation. Traditional methods often take a long time to calculate large-scale light fields, and the real-time application of light field calculations is also limited.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a super-resolution light field acquisition device and a three-dimensional reconstruction method thereof. Background technique [0002] Light field acquisition and reconstruction technology is a very important issue in the field of computer vision. The use of light field for 3D reconstruction has great advantages over traditional 3D reconstruction methods: it requires less hardware resources and is easy to implement in real time on a PC. Reconstruction; no cumbersome human-computer interaction is required, the applicability is strong, and the complexity of the scene will not increase the complexity of the calculation. However, although high-precision 3D reconstruction can be performed using a 3D scanner, its expensive equipment and very limited use occasions limit its practical application. Light field technology has a wide range of applications in lighting engineering, l...
