The work presented here describes a novel vision-based motion detection system for telerobotic operations. The system uses a CCD camera and image processing to detect the motion of a master robot or operator. Color tags are placed on the arm and head of a human operator to detect the up/down, right/left motion of the head as well as the right/left motion of the arm. The motion of the color tags are...
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...
This paper presents a novel method by regulating the height of a CCD camera to measure the width and height of a targeted object. That is, three-dimensional measurement can be obtained with the use of a single CCD camera. To facilitate the measurement using various kinds of CCD cameras, parameters pertinent to the cameras can be established via a proposed mechanism in this paper. As a result, any...
In this paper, we use two visible laser points as the measuring ruler for automatically adjusting measurement. It is a breakthrough compared with using double CCD cameras or the measuring method of setting up reference at measuring points. By using a single image, we can realize the non-contact distance measurement. The measuring principle is to produce two bright projection spots on the measuring...
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...
