This paper presents a sensor fusion framework that incorporates a monocular vision system, laser range finder and an inertial navigation sensor (INS) for localization of mobile robots and manipulators. The proposed method is particularly useful for applications in which there is a featured wall or floor in proximity to the robots. Examples include unmanned ground vehicles (UGV), unmanned aerial vehicles...
This paper presents an academic prototype small humanoid robot with vision-system to achieving the posture estimation. With the on-board personal digital assistant (PDA) to in charge of the image processing and then recognize its surroundings. According to the information of the image data from the PDA-based real-time image sensor, the Nios-based motor control chip is employed to achieve the desired...
In this paper, chess-type plane is used as calibration patterns, and the camera is calibrated by utilizing linear camera model with sub-pixel precision, we propose an improved algorithm used to locate the position with the visual information. The new method is based on improved SUSAN detecting and is combined with quick image matching which is used to get the coordinates of the end executor of the...
This paper provides an image-based localization method based on tilt photographing of a single CCD camera. Image captured by the CCD camera is pre-processing to locate the target object in the picture in terms of pixel count deviation from the CCD camera. By using an established formula based on relationship between tilt angle of the CCD camera and distance, coordinate of the target object can be...
