Large depth of field digital imaging method based on single-lens imaging

Abstract

The invention discloses a large depth of field digital imaging method based on single-lens imaging. The method comprises the following steps: S1, performing imaging on light sources with different wave lengths through a light path system, wherein the light path system performs the imaging through the optical principle by using the single-lens; S2, performing image data acquisition on the image data in the light path system through an acquisition system; and S3, performing image processing on the acquired image data through an image processing system. The imaging method disclosed by the invention has the advantages that the acquisition system acquires the image data in the light path system to realize the data acquisition; a USB system realizes the data transmission to the image processing system from the acquisition system; the image processing system processes the image by using a histogram method, and the image matching ratio is improved; the image is sharpened by using an unsharp mask method to form an edge highlight effect, thereby improving the image resolution, and enabling the color at the image specific region to be more bright.

Description

technical field [0001] The invention belongs to the technical field of optical imaging for expanding depth of field, in particular to a digital imaging method for large depth of field based on single-lens imaging. Background technique [0002] In the field of optical imaging, depth of field refers to the object distance range measured along the axis of the imager in front of the lens or other imager to obtain a clear image. In many imaging fields, it often happens that when two or more subjects are photographed, all subjects cannot be captured clearly at the same time (the subjects are outside the depth of field of the imaging system). If the object is outside the depth of field of the imaging system, the imaging system cannot focus on multiple objects at the same time, and the image of the object that is not in the focal plane of the system must be blurred. Therefore, when the depth of field of the imaging system is too small, the imaging system cannot realize clear imagin...
