Claim 11:
12. A matrix image acquisition system, comprising at least two image acquisition systems,
wherein each of the at least two sets of 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 at least two image acquisition system comprises a central image acquisition system and at least one adjacent image acquisition system, the condenser lens and the image sensor in the central image acquisition system are arranged coaxially, and the condenser lens and the image sensor in the adjacent image acquisition system are arranged non-coaxially;
wherein the image-side image on the imaging plane position in each set of image acquisition system has an eccentricity value, the eccentricity value is a distance between the image-side image and an axis of the condenser lens in each image acquisition system, the eccentricity value is δn, and δn=K×n×D×(Li÷Lp), where n≥0; and
wherein 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 a condenser lens in each adjacent image acquisition systems and a condenser lens in the central image acquisition system, the K value is used to indicate an influence of a thickness of the condenser lens on the eccentricity value, the K 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 distance D between the condenser lenses.
