During a design procedure of association rule mining approach, there are two common issues: the transformation method from continuous quantitative attributes to qualitative concepts, and efficiency of data mining. In order to acquire association rules in a database with different types of attributes, the cloud transformation which is included in the cloud model theoretical framework is applied as...
According to the conceptualization habit of human cognition and perceiving characteristics of the human eyesight, a novel high-dimensional data visualization method, which combined uncertain concepts extraction methods and visualization techniques, is proposed in this paper. The technical framework of generating a concept color spectrum diagram of a high-dimension data record is presented. The cloud...
In the complex natural background, the image features of spatial dynamic objects usually change severely, so target recognition method based on single feature could not adapt to the recognition requirements. Due to unpredictable changes of target distance, finding real-time solution of image Jacobi matrix is more difficult, so as achieving active visual servo of spatial dynamic target. Inspired by...
Since the word mechatronics was created in 1960s, the connection in physical level of mechanical and electronic subsystems and power driving had been gradually realized. By the end of 1980s, it was emphasized that the control of mechatronics systems was based on sensor information, scilicet the concept of information-driven. At the turn of the century, more and more researches and applications concentrated...
Based on binocular stereo vision sensor measurement model, a kind of low cost single rotating angle indexing camera method used to measure distance of a remote object was presented in this paper. A single camera was mounted on a rotating platform, which was driven by a step motor or equipped with an angle encoder, so that the rotating angle of camera could be indexed. Two parallax images which projected...
Aiming at solving the problem of trajectory tracking of the wheeled mobile robot, the paper presents an adaptive trajectory tracking method based on the kinematics model. After analyzing the shortage of classical trajectory tracking control rule, the idea of the single point preview is introduced to the method to improve the effect of trajectory tracking, as well as an artificial field is combined...
