摘要

A Projector-camera (Procam) system is an inexpensive,household,controllable system that can be used to eliminate inter-reflection existing in the measurement.We propose an estimation method for spectral reflectance that uses the Procarn system.The method recovers reflectance from the training set constructed by a known reflectance and the corresponding 9D color-mixing matrix.Experiment results show that our method performs well with 9D response,and the local weighted training set based on Mahalanobis metric can enhance the accuracy of result efficiently.
