Abstract

The invention provides a space-time joint optimization reconstruction system based on a scanning light field microscopic imaging system. The space-time joint optimization reconstruction system comprises a scanning light field acquisition module, a preprocessing module and a time-space joint bidirectional circulation reconstruction module. The invention further provides a space-time joint optimization reconstruction method based on a scanning light field microscopic imaging system. The space-time joint optimization reconstruction system and method add space-time joint constraints, optimize traditional reconstruction algorithm, greatly increase the reconstruction speed, effectively reduce the three-dimensional reconstruction time, recover the volume imaging time resolution, namely the time resolution sacrificed by scanning, and meanwhile, eliminate motion blur and artifacts caused by too fast change of a sample, so that the performance of a scanning light field microscopic imaging systemis improved, and the application of the scanning light field microscopic imaging system in scenes such as biological tissue high-speed capture is expanded; and for the whole time delay three-dimensional video, the time bidirectional circulation algorithm mainly utilizes the continuity and redundancy of four-dimensional information in the time dimension, and the whole signal-to-noise ratio can beimproved.

Description

technical field [0001] The invention belongs to the technical field of image three-dimensional reconstruction, and in particular relates to a method and system for combined spatiotemporal optimization and reconstruction based on a scanning light field microscopic imaging system. Background technique [0002] Three-dimensional imaging has always been a hot frontier in the field of microscopic imaging research, and it is of great significance for scientists to explore the mysteries of life and the mechanism of diseases. Scanning light field microscopy imaging system is an important three-dimensional imaging technology. It introduces sub-pixel translation into the traditional light field microscopy imaging system, overcomes the low spatial resolution problem of traditional light field microscopy, and achieves diffraction-limited imaging. At the same time, the acquisition speed of the scanning light field microscopy imaging system can reach 100Hz, which can be applied to many s...
