End-to-End Projector Compensation

Abstract:

Projector compensation aims to modify a projector input image such that it can compensate for geometric correction and photometric disturbance of the projection surface. The photometric process in a projector-camera (ProCam) system involves many complicated factors, making it very difficult for traditional solutions. In this work, we propose end-to-end solutions by that implicitly address real-world challenges. First, we formulate the compensation problem as an end-to-end learning problem and propose a convolutional neural network, named CompenNet, to implicitly learn the complex compensation function. CompenNet consists of a UNet-like backbone network and an autoencoder subnet. Then, we further extend CompenNet by integrating a geometric correction subset for geometric compensation, while remaining end-to-end trainable. For evaluation, we construct the first setup-independent full compensation benchmark to facilitate the study on this topic. In our thorough experiments, our method shows clear advantages over previous arts with promising compensation quality and meanwhile being practically convenient. This is a joint work with Bingyao Huang.
