Portable all-weather active panoramic vision sensor

Abstract

The invention discloses a portable all-weather active panoramic vision sensor. The portable all-weather active panoramic vision sensor comprises an all-directional vision sensor capable of fusing polarization imaging through which light intensity and polarized light information are output with a panoramic picture, a panoramic laser light source and a microprocessor for performing 3D panoramic reconstruction on an all-directional image; the center of the multi-source output all-directional vision sensor and the center of the panoramic laser light source are arranged on the same axis; the microprocessor comprises a calibration part and a 3D reconstruction part; the calibration part mainly comprises a multi-source output all-directional vision sensor calibration module and a joint calibration module; the 3D reconstruction part mainly comprises a panoramic laser light source emission angle position estimation module, a panorama plane laser information analysis module, a panorama plane point cloud geometry information computation module, a point cloud geometry information and color information fusion module, and a construction module for constructing a panoramic 3D model according to panoramic plane position information. According to the portable all-weather active panoramic vision sensor, functions of portable all-weather active panoramic perception and automated 3D panoramic modeling are realized.
