"Comparative study on 3D optical sensors for short range applications", Optics and Laser Technology (2021)
/Abstract
The increasing availability of commercial 3D optical sensors drastically benefits the mechatronics community by providing affordable sensing means for perception and control. Yet, to our knowledge, there are no comparable study to the state-of-the-art 3D optical sensors, making it difficult for users to select for their specific applications. This paper evaluates the performance of each sensor for short range applications (i.e., $\le$ 1 m ). Specifically, we present our findings on the measurement accuracy of each sensor under ``ideal'' situations, compare the influence of various lighting conditions, object surface properties (e.g., transparency, shininess, contrast), and object locations. In addition, we developed software APIs and user instructions that are available for the community to easily use each of the evaluated commercially available 3D optical sensor.
