Time-of-Flight cameras are active sensors that able to capture both the light intensity reflected by each observed point in scene and distance between these points camera. Enhancing images with a depth modality enables capturing surfaces 3D boosts applicability of sensors. Nevertheless, high-level information still needs be extracted from data stream order accomplish tasks, like recognition or ...

Abstract Pose estimation of construction machines describes their motions and orientations in 3D space, which provides basic information for remote control, safety monitoring, productivity analysis. Among the commonly used machines, excavator is an important one whose pose has significant value development automatic driving systems operation monitoring. Regarding vision-based excavators, previo...

When using a monocular camera for detection or observation, one only obtain two-dimensional information, which is far from adequate surgical robot manipulation and workpiece detection. Therefore, at this scale, obtaining three-dimensional information of the observed object, especially depth estimation surface points each has become key issue. This paper proposes two methods to solve problem def...

We present a system that allows for changing the major camera parameters after the acquisition of an image. Using the high dynamic range composition technique and additional range information captured with a small and low-cost time-of-flight camera, our setup enables us to set the main parameters of a virtual camera system and to compute the resulting image. Hence, the aperture size and shape, ...
