Problems solved by technology
[0003] However, the inventors found that most of the existing light field imaging arrays are in a static non-adjustable state, and cannot be adjusted when the light field imaging effect is not good; or although they can be adjusted, they are also based on human experience and lack objectivity; in addition , in the case of multi-target imaging and tracking, the synchronization and registration parameters of the light field imaging array (multiple light field cameras included in the light field camera array) will greatly affect the imaging effect

The invention provides a light field imaging method and system based on a perceptual model, and belongs to the technical field of light field imaging. The system comprises a camera calibration module, a color interpolation module, an image enhancement module and a super-resolution reconstruction module and is connected with a light field camera array. The super-resolution reconstruction module is used for performing super-resolution reconstruction on the region subjected to image enhancement and the neighborhood of the region; the perception model perceives the number of predetermined types of targets contained in a region where the image enhancement module performs image enhancement and a neighborhood thereof, and adjusts state parameters of the light field camera array. A method includes performing time synchronization on a plurality of first light field cameras included in a light field camera array. Reconstruction errors caused by time parameter inconsistency of the light field camera in the light field imaging process are eliminated, calibration, color interpolation and enhancement are carried out on the target of the preset type, and the light field imaging effect is improved.
Description
technical field [0001] The present invention belongs to the technical field of light field imaging, and in particular relates to a light field imaging method and system based on a perception model, a computer system for implementing the method, and a computer-readable storage medium. Background technique [0002] Traditional imaging techniques project a 3D scene onto a 2D sensor plane, losing the original depth information. Depth information has been proven to be effective in improving computer vision capabilities, such as detection, segmentation, and recognition. Correspondingly, the light field camera can record the 4D light field information such as the space and angle of view of the 3D scene through a single exposure to form light field imaging, which is a significant innovation compared with the traditional camera 2D image acquisition method. As the cost of cameras decreases, designing a light field camera array to collect light field data to realize light field imagin...
