Method and system for improving image frame frequency based on double-camera system light-splitting imaging

Abstract

The invention discloses a method and system for improving the image frame frequency based on double-camera system light-splitting imaging, relates to the technical field of image processing, and solves problems that a conventional method for improving the image frame frequency is low in calculation precision and the video quality is affected because the conventional method for improving the image frame frequency is affected by parallax. The system comprises a main mirror, an auxiliary mirror, a first reflector, a second reflector, a beam shrinking system, two imaging lens, a light-splitting lens, two EMCCD cameras, a timing system controller, and a computer. Incident light is reflected by the main mirror and the auxiliary mirror, and then enters the beam shrinking system, thereby enabling the exit pupil of the beam shrinking system to be located on the front surface of the light-splitting lens. Moreover, the diameter of a light beam is matched with the size of the light-splitting lens. The incident light is divided by the light-splitting lens into reflected light and transmitting light, and the reflected light and transmitting light respectively pass through a first imaging lens group and a second imaging lens group to be received by the first EMCCD camera and the second EMCCD camera. The system employs a time sequence controller to externally trigger the two cameras for exposure and imaging in an alternate manner, and improves the sampling frame frequency of a reconstructed video image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for improving image frame rate by using dual-camera spectroscopic imaging. Background technique [0002] At present, with the rapid development of digital image equipment, EMCCD cameras are playing an increasingly important role in low-light detection, adaptive optics, photoelectric countermeasures and other fields. EMCCD cameras are often difficult to balance high frame rate and high resolution. In order to improve The frame rate of the image and other performances of the EMCCD camera will inevitably be affected, and the cost of the equipment will also be greatly increased. [0003] Chinese patent CN 201410274363.4 discloses a method for improving image frame rate and resolution based on multi-cameras, which uses a multi-camera structure-like compound eye imaging system and low-resolution video images of the same scene to reconstruct high-resolution ...
