Abstract: A 3D spatial scanning system and method can perform accurate 3D spatial scanning in various environments. The 3D spatial scanning system may include a sensor group, a confidence estimator, a function adjuster, and a fusion part. The sensor group may scan space using a time-of-flight (ToF) sensor and a stereo red-green-blue (RGB) sensor included therein. The confidence estimator may fuse a sensing value of the ToF sensor and a sensing value of the stereo RGB sensor and estimate a confidence of the sensing values. The function adjuster may adjust a function of at least one of the ToF sensor and the stereo RGB sensor based on the confidence estimated by the confidence estimator. The fusion part may fuse the sensing value of the ToF sensor and the sensing value of the stereo RGB sensor based on function adjustment of the function adjuster.
