Proposed in this paper is an illumination radiation-based optical flow field model for the motion detectionof various objects in different environments. In the investigation,first,the parameters of the general dynamic imagemodel are explained and amended in the Clifford algebra region. Then,according to the results deduced in the Cliffordalgebra region and obtained from experiments,a new optical flow field model is proposed based on the principleof movement vision-generating principle and the illumination radiation theory,to which a gradient field is appliedfor the purpose of improving the accuracy. Finally,a total variation algorithm is presented for the proposed model. Experimental results show that the proposed model can achieve accurate,continuous and consistent optical flowfields for the purpose of being generally used in different illumination conditions.
