RGB-D Automatic Calibration for RGB-D and Thermal Sensor Fusion and Method thereof

摘要

An automatic calibration system and method for thermal image sensor and RGB-D sensor fusion are presented. An automatic calibration method for fusion of a thermal image sensor and an RGB-D sensor includes the steps of acquiring a thermal image through a thermal image sensor and acquiring an RGB image through an RGB sensor to detect a subject image in the thermal image and the RGB image; Assuming that an edge or a center of the subject area is a pixel that matches each other; And obtaining a plurality of the pixels to obtain a transformation matrix for calibration of the thermal image and the RGB image.
