A novel image-based label system is proposed in this paper, we can convert the coordinate in image into Cartesian coordinate by using an image from a single CCD camera. This system could correspond arbitrary two points on the image convert to the actual distance no matter the digital camera is vertical to the measuring plane or not and the height of digital camera. Here designed a new structure for...
After Taiwan's 88 floods, landslide monitoring system is getting more important. A novel non-contact landslide monitoring system for long distance is proposed in this paper, using a single image to achieve monitoring, measuring displacement and direction. The method of landslide monitoring system is not measuring land appearance displacement, so do not compare the before and after image to calculate...
Visual servoing, using the visual measurements direct in the control loop, is a problem that in recent years has grown in interest. One of the main problems involved in these systems is that, while the robot manipulator has a well known model and identification methods have been available, the vision system introduces a nonlinear transformation and modifies the dynamics as seen in the image plane...
We present a simple and efficient method to seamlessly stitch the images according to a stitching line based on an energy map. The power of this method lies in the integration of many superior features and at the same time, it is still efficient. One striking feature of our approach is that it is based on the philosophy that human eyes mostly notice only the salient features of an image and the stitching...
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...
