Most SLAM (Simultaneous Localization and Mapping) algorithms are based on the assumption that scene is static. However, in practice, most real scenes usually contain moving objects. In this letter, we introduce DymSLAM, a dynamic stereo visual system being capable of reconstructing 4D (3D + time) with rigid Unlike previous attempts have considered objects as outliers ignored them, DymSLAM obtai...

Nowadays lidar and photogrammetric surveys have been used together in many mapping procedures due to their complementary characteristics. Lidar survey is capable to promptly acquire reliable elevation information that is sometimes difficult via photogrammetric procedure. On the other hand, photogrammetric survey is easily able to get semantic information of the objects. Accessibility, availabil...

The combination of light detection and rangings (LiDARs) cameras enables a mobile robot to perceive environments with multimodal data, becoming key factor in achieving robust perception. Traditional frame are sensitive changing illumination conditions, motivating us introduce novel event make LiDAR-camera fusion more complete robust. However, jointly exploit these sensors, the challenging extri...

In this paper we present a way to automatically recover camera orientation in an eye-in-hand system. The algorithm is completely automated performing a sequence of rotations and translations iteratively until the camera frame has been successfully aligned with the manipulators world frame. The system we have developed has been fully implemented and tested on a Staubli RX60 robotic arm using an ...

A vision system to gauge two types of automotive parts has been developed. One of the part types is a power steering connector in which the depth and width of the groove, and the distance between the start of the groove and the end of the power steering line are gauged. For the second type of part, a crimped connector attached to a brake hose, measurements of interest are the two diameters of t...

The paper suggests about with using of real time color segmentation, filtration and feature selection process to draw the patterns with major use of image processing i.e., Drawing the different shapes using the double tap of fingers, open the hand and change the color of given shape.so basically Vision-based human–computer connection could be achieved by determining separated primary color area...

In this paper we consider the problem of recovering 3D Euclidean structure from multi-frame point correspondence data in image sequences under perspective projection. Existing approaches rely either only on geometrical constraints reflecting the rigid nature of the object, or exploit temporal information by recasting the problem into a nonlinear filtering form. In contrast, here we introduce a ...

This paper describes the design and implementation of a architecture that can continously monitor and track selected face in real time by controlling camera motion around. Dection and tracking of face has been an significant and dynamic investigation domain because it provides many application, primarily in video coding, video surveillance, biometry or Video Identity Resolution. But detection a...
