AI Technical Summary

Technical Problem

The existing multispectral image acquisition device has fewer image acquisition components, resulting in insufficient number of spectral segments, low picture quality, and fixed direction of the acquisition lens, and low field of view utilization.

Method used

A variable bionic curved surface compound eye structure and multi-spectral image acquisition device are designed, and nine image acquisition components are used to form a 3×3 rectangular array. The image acquisition board numbered 1 to 3, 4, 6 and 7 to 9 is controlled to rotate to the image acquisition board numbered 5 at the same time, increasing the acquisition overlap area and improving the field of view utilization.

Benefits of technology

It realizes nine spectral segment acquisition of the same target object from the same plane, provides more comprehensive spectral information, improves the final imaging quality, and improves the field of view utilization of the image acquisition sensor.
