Micro-quadrotor usually equips with lightweight sensors due to its limited payload. In this paper, an odometry estimation method based on 2D laser scanner and monocular vision is proposed to solve the pose estimation problem of micro-quadrotor flying robot in indoor environments. This method firstly detects and matches image features of current and previous frames to get all feature correspondences...
This paper deals with a seam tracking system of welding of tailored weld blanks based on active laser-triangulation. The system consists of DSP based vision camera and stripe-type laser diode. The total system is assembled into a compact module which can be attached ahead of welding torch and it has high dynamic performance in guiding the robot arm welder accurately over the seam. its structure, basic...
An vision inspection sensor system for the automation of laser welding processes in heavy industries is presented. The system consists of PC based vision camera and stripe type laser diode. For image de-noising, a new surface inspection method of Tailor-welded blanks including in: median filtering, bi-level thresholding, opening and closing, mid-line of the laser stripe extraction, has been developed...
