Vostok: 3D scanner simulation for industrial robot environments

Abstract

Computer vision will drive the next wave of robot applications. Latest three-dimensional scanners provide increasingly realistic object reconstructions. We introduce an innovative simulator that allows interacting with those scanners within the operating environment, thus creating a powerful tool for developers, researchers and students. In particular, we present a novel approach for simulating structured-light and timeof-flight sensors. Qualitative results demonstrate the efficiency and reliability in industrial environments. By using the programmability of modern GPUs, it is now possible to make greater use of parallelized simulative approaches. Apart from the easy modification of sensor parameters, the main advantage in simulation is the opportunity of carrying out experiments under reproducible conditions, especially for dynamic scene setups. Moreover, thanks to a great computational power, it is possible to generate huge amounts of synthetic data which can be used as test datasets for training machine learning models.

“…In some cases, it can be a considerable part of the total mesh, leading to a waste of system memory and a significant decrease in performance. Actually, this problem arises in heavily based ray tracing applications, such as 3D scanner simulators [ 3 ]. In this scenario, an algorithm is essential for reducing the number of triangles without losing useful information.…”
