Method for seamlessly splicing based on three lenses and area array detectors

A seamlessly splicing method based on three lenses and area array detectors, comprising:

• imaging a field of view simultaneously using the three lenses;
• arranging three area array detectors at corresponding focal plane positions of each of the three lenses to obtain imaging images, respectively;
• generating a complete seamlessly imaging result of the field of view by pairwise splicing the imaging images obtained from adjacent area array detectors, through staggered splicing of the three lenses and/or the area array detectors,
• wherein row or column pixel elements of the imaging images of the adjacent area array detectors are overlapped by an overlapping width of not less than one pixel,
• wherein each area array detector comprises a plurality of area array detection units arranged in a checkerboard pattern having a predetermined spacing, wherein, a total number of area array detection units in each area array detector is m×n;
• where m is a number of area array detection unit in each row and n is a number of area array detection unit in each column,
• wherein adjacent lenses are arranged at an angle in horizontal direction that is parallel to corresponding area array detectors;
• and the imaging images of the adjacent area array detectors are pairwise spliced by splicing lens field of view, so that the row or column pixel elements of the adjacent area array detectors are overlapped,
• wherein the adjacent lenses form a misaligned overlapping on an image plane of the corresponding area array detector, and a misaligned overlap width is a difference in image height formed by the adjacent lenses.
