The invention discloses an automatic all-focus imaging method and device. The automatic all-focus imaging method includes: S01 obtaining a depth value distribution map of a scene through a microlens array, wherein the microlens array includes a plurality of microlens units arranged in an array, and each microlens unit corresponds to the depth S02 obtains the position information of each microlens unit corresponding to the subimage; S03 calculates the depth mean value of each microlens unit corresponding to the subimage; S04 uses the depth mean value of each microlens unit to obtain the corresponding microlens The driving voltage for the unit to focus on the region of interest of the scene; S05 drives each microlens unit to focus on the corresponding region of interest to generate a full-focus image. The automatic full-focus imaging method and device of the present invention have the beneficial effects of simple implementation of full-focus imaging and good imaging quality.
Description
technical field [0001] The invention relates to the field of optical technology, in particular to an automatic all-focus imaging method and device. Background technique [0002] At present, in various fields such as industrial inspection, security inspection, and high-altitude detection, the depth of field of the imaging system is often not large enough, which affects the wide application of the imaging system. In the prior art, there are various methods for extending the depth of field to form an all-in-focus image. [0003] Reference 1 (CN103533232A) discloses an image processing device and image processing method for an omni-focus image. The image processing method mainly includes: an image acquisition step, acquiring data of multiple camera images shot at multiple focus positions; a step of determining, for the data of a plurality of captured images, an order different from the order of focus distances as a combined order; The data of the images are combined to generat...
