We propose a method for estimating depth from single-view terrain landscapes using convolutional neural networks (CNNs). The existing depth estimation methods using CNNs mainly target at near-distance views (e.g., indoor scenes), and often suffer from large-scale scenes with significant depth range. We attribute this performance degradation to the difficulty of training due to considerable depth variations. In this work, we integrate a CNN for classifying depth distributions inferred from input images on top of depth estimation to alleviate the influence of depth variations during training and inference. We first classify training data into several depth classes and train a depth-estimation CNN for each class. During inference, we obtain a final depth map by calculating a weighted average of outputs from class-wise CNNs, whose weights are obtained as likelihoods inferred by the depth-classification CNN. We attempt more accurate depth estimation for terrain landscapes with this proposed framework. |
