Abstract

The invention relates to an image acquisition method which comprises the following steps: receiving a trigger signal, and generating a sampling control signal and a light source control signal according to the trigger signal; according to the light source control signal, alternately generating n optical scenes at a scene switching frequency k0 in an image acquisition process; according to the sampling control signal, carrying out image acquisition on a sampled object at a line frequency k1 under n optical scenes alternately generated at a scene switching frequency k0 to obtain an image pixel signal, wherein k1 = N * k0, and N is an integer greater than or equal to n; and performing image separation on the image pixel signals to obtain acquired images corresponding to the n optical scenes.According to the invention, only one set of camera and the industrial personal computer for controlling the camera are used to realize acquisition of a plurality of optical scene images at one time, so that the use cost and the maintenance cost of the system are reduced, and the image acquisition efficiency is improved. The invention further comprises an image acquisition system.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an image acquisition method and system. Background technique [0002] In the machine vision inspection industry, the same system is often equipped with multiple optical solutions to meet the needs of multiple inspection items. For example, some require light and dark optical scenes, some require red, green and blue optical scenes, and so on. In actual detection applications, it is necessary to configure multiple sets of cameras corresponding to multiple sets of optical solutions for image acquisition. This matching method needs to increase the number of cameras and industrial computers that control the cameras, as well as the number of camera transmission cables and camera power interfaces. It will make the internal circuit of the device more complicated, the operable space will be smaller, and the use cost and maintenance cost of the entire system will be increased, ...
