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 have certain limitations in depth estimation and 3D imaging; at the same time, the current Light field imaging technology has not yet considered the image wide dynamic requirements in the advanced visual perception environment; in addition, the acquisition and editing of the region of interest is currently based on the geometric position modeling of the camera, which is still insufficient in accuracy and flexibility, and in the process of improving the depth of field Medium and heavy focusing points need to be manually specified, which cannot meet the actual needs of advanced visual cognition tasks
