This paper introduces an optimization energy framework based on infrared guidance to improve depth consistency in Time of Flight image systems. The primary objective is to formulate the problem as an image energy optimization task, aimed at maximizing the coherence between the depth map and the corresponding infrared image, both captured simultaneously from the same Time of Flight sensor. The concept of depth consistency relies on the underlying hypothesis concerning the correlation between depth maps and their corresponding infrared images. The proposed optimization framework adopts a weighted approach, leveraging an iterative estimator. The image energy is characterized by introducing spatial conditional entropy as a correlation measure and spatial error as image regularization. To address the issue of missing depth values, a preprocessing step is initially applied, by using a depth completion method based on infrared guided belief propagation, which was proposed in a previous work. Subsequently, the proposed framework is employed to regularize and enhance the inpainted depth. The experimental results demonstrate a range of qualitative improvements in depth map reconstruction, with a particular emphasis on the sharpness and continuity of edges. © 2024, Springer Nature Switzerland AG.
