Abstract

The invention relates to a design method of a high-performance imaging system. The design method comprises the following steps: calculating a required resolution required to be met by an image sensor according to application requirements; searching an image sensor matched with the required resolution; if not, determining the image sensor corresponding to the actual resolution which is closest to the required resolution and is one level higher than the required resolution; calculating the physical size corresponding to the required resolution according to the required resolution, the actual resolution and the physical size corresponding to the actual resolution; determining a lens corresponding to the required resolution and a lens corresponding to the actual resolution according to the physical size corresponding to the required resolution and the physical size corresponding to the actual resolution; comparing whether the lens apertures are consistent or not; and if the lens aperture corresponding to the actual resolution is greater than the lens aperture corresponding to the required resolution, selecting a lens corresponding to the required resolution and an image sensor corresponding to the actual resolution. According to the invention, high-performance requirement of the imaging system can be met, and the processing amount of the imaging system can be effectively reduced.

Description

technical field [0001] The present application relates to the field of visual imaging technology, in particular to a design method of a high-performance imaging system. Background technique [0002] The imaging system in industrial vision mainly includes camera, lens, acquisition card (optional), light source, and power supply. Among them, the camera is the core device of the imaging system, and its performance is mainly determined by the image sensor. The resolution, pixel size, and circuit design of the image sensor will determine the size of the image sensor, and the size of the image sensor will affect the selection of the lens. Usually, in order to make full use of the full resolution of the image sensor and for better image quality, a lens with an aperture larger than the target surface size of the image sensor is selected, such as figure 1 As shown, the lens aperture indicates the maximum light entrance of the lens, that is, the maximum aperture of the lens. [0003...
