The invention discloses a configurable multispectral remote sensing stereo imaging system and a design method, and relates to the technical field of multispectral inclined remote sensing imaging. The objective of the invention is to solve the problem of limited inclined image information acquisition capability of an existing multi-spectral imaging system based on an unmanned aerial vehicle, and the problem of lack of acquisition synchronism and accumulative errors among multiple cameras. Aiming at the multi-angle multi-spectral data acquisition requirement of a complex remote sensing scene, a configurable camera mounting structure, a synchronous trigger control module and a camera internal and external parameter calibration method are designed, and a hinge type structure and a fixed bolt are adopted to realize the functions of camera number configuration and inclination angle adjustment; based on a microcontroller and a pulse width modulation technology, a camera synchronous triggering module is designed and developed to realize data synchronous acquisition, a multi-camera calibration method is designed and developed to obtain an accurate spatial transformation relation between cameras, and correction of multi-camera position and attitude information is realized.
