Description

technical field [0001] The present invention relates to technical fields such as computer vision, optical engineering, computer graphics, pattern recognition, artificial intelligence, etc., especially a light field imaging device and method for visual computing, which can realize large depth of field, wide dynamic range, true three-dimensional, high resolution , Light field imaging that will be edited. Background technique [0002] Vision is the most important source of information for humans to perceive the world. Visual computing attempts to endow machines with the ability to automatically obtain high-level semantic knowledge of physical scenes from image and video data. Economic and social development has important practical value. Solving behavior and event analysis in complex environments in real scenes is an important challenge in the field of visual computing. Traditional imaging devices follow the imaging principle of directly acquiring two-dimensional image inform...

Problems solved by technology

[0007] Light field imaging technology has a great advantage in increasing the depth of field of the image, and the effect of refocusing the foreground and background of the image is satisfactory, but there are still some problems when it is directly applied to the visual perception scene. First, due to the spatial resolution and angle resolution Due to the contradictory relationship between the existing light field imaging devices, there is generally a problem of low image spatial resolution; secondly, the imaging devices that only rely on the existing light field acquisition form still hav...
