Claim 0:
1. A matrix image acquisition system, comprising at least two image acquisition systems, wherein each of the at least two image acquisition systems comprises:
an object area configured to form an image on an image side;
a condenser lens configured to converge light from the object area, the condenser lens being located on a light path of the object area;
a color filter configured to filter the light collected by the condenser lens to obtain single wavelength of light, the color filter being placed in front of the condenser lens according to a forward direction of the light; and
an image sensor configured to receive an image-side on an imaging plane position of an image space, the image sensor being placed in front of the imaging plane position according to the forward direction of the light,
wherein the image-side image on the imaging plane position has an eccentricity value, the eccentricity value is δn, and δn=K×n×D×(Li÷Lp), where n≥0, a distance between the condenser lens and the imaging plane position is an image-side focal length Li of the image acquisition system, a distance between the condenser lens and the object-side region is an object-side focal length Lp of the image acquisition system, the D is a distance between condenser lenses in the at least two image acquisition systems, the K is used to indicate an influence of a condenser lens thickness on the eccentricity value and is determined according to optical parameters of the matrix image acquisition system, and the n is an integer multiple of an object height of the image acquisition system relative to the spacing D between the condenser lenses.
