英文摘要： A novel system for measuring the three dimensional topography of large targets is developed based on bionics. A highly integrated design is adopted to overcome the disadvantages of the existing system, such as complex structure, high weight, high power consumption and low reliability. 3D coordinate of each point on the large objectives is captured by lens array with curved surface, and use the refractive lens to optimize the optical part of the system, and complete the high-speed image acquisition, high-speed data transmission and real-time processing tasks by making full use of the rapid development of technology of the image sensor and electronics equipment.we have researched the assemble methods and standards for Lens array on a curved surface, implemented Imaging system calibration tasks through establish corresponding targeting model and build calibration platform.The algorithm obtaining a ctual center of facula is explored, and the key issue matching the channel among the compound eye for each imaging point is solved. Based on two developed compound eyes, the measurement accuracy and measurement efficiency for 3-D topography are evaluated and analyzed. Establish a theory system and experimental methodology based on the fabrication, calibration and measurement of large field-of-view compound eye .
