  • The purpose of rhis research is proposing rhe sysrem which does information supporr as for a truck driver, and verifying the validity. First, it investigated by visiting the Transporr Company and interview for the present situation and the opinion on computerization from the operation administrator and truck drivers. Consequently, the problem of computerization could be found out to the present system. Next, the present system was considered. As for present machine system, human's "Choosing a function", srarts processing. Then this system is called "Function-Oriented-System". And three problems were extracted from this sysrem. As a solution of those problems, the Purpose-Oriented-System was proposed. In order to attain user's purpose, Agent that situation is perceived and works a function autonomously assumed that this system was inherent. 3D-Sceanrio-Expression was proposed as the description method of rhe task process. It consists of "Machine and Functional-Item axis", "Time axis", and "Situation-Item axis". And, the task execution process of Function-Oriented-System and Purpose-Oriented-System was compared using 3D-Sceanrio-Expression supposing the scene of truck business. As a resulr, rhe following two things could be found out. (1) The concepr of Purpose-Oriented-System that Agent is inherent is effective as siruarion correspondence machine. (2) A solid scenario can express the interaction rhar cannor be seen, in the relarion of rhe conventional Human and Machine.

  • Recently, robotic bin-picking tasks have drawn considerable attention, because flexibility is required in robotic assembly tasks. Generally, stereo camera systems have been used widely for robotic bin-picking, but these have two limitations: First, computational burden for solving correspondence problem on stereo images increases calculation time. Second, errors in image processing and camera calibration reduce accuracy. Moreover, the errors in robot kinematic parameters directly affect robot gripping. In this paper, we propose a method of correcting the bin-picking error by using trinocular vision system which consists of two stereo cameras andone hand-eye camera. First, the two stereo cameras, with wide viewing angle, measure object's pose roughly. Then, the 3rd hand-eye camera approaches the object, and corrects the previous measurement of the stereo camera system. Experimental results show usefulness of the proposed method.

  • The purpose of this paper is to explore the concept of the fitness and the way of the inspection in the Leadership study. Although the study of the fitness is recently increased, however, the concept recognition and the positive analysis on the inspection of the fitness isn't in the saddle and by inspecting after the operationalization, the theory and the result don't often correspond. So, This study is to help the following study and provide the conception and the problem of the analysis on the centering the fitness of the moderator and the mediation.

  • The panorama is a good alternative to overcome narrow FOV under study in robot vision, stereo camera and panorama image registration and modeling. The panorama can materialize view with angles wider than human view and provide realistic space which make feeling of being on the scene based on realism. If we use all correspondence, it is too difficult to find strong features and correspondences and assume accurate homography matrix in geographic changes in images as load of calculation increases. Accordingly, we used SURF algorithm to estimate overlapping areas with high similarity by comparing and analyzing the input images' histograms and to detect features. And we solved the problem of input order so we can make panorama by input images without order.

  • In this paper, a lens actuator for mobile devices is proposed using stack type piezoelectric materials. In general, the deformation of PZT actuators is not enough for lens motion when the allowed voltage is applied. The small stroke problem can be solved by accumulating a lot of small displacements in high frequency. In this paper, a new inch-worm type model for focusing actuator is suggested based on the interaction of inertial and frictional forces. Theoretical analysis and simulation using ANSYS are performed to verify the feasibility of the inch-worm PZT actuator model. Various types of clamps are considered to determine the effect of frictional force on the motion, and appropriate clamp-actuator models are proposed. The proposed models are experimentally verified and the experimental results show high correspondence with theoretical and simulated values. The inch-worm type focusing actuator enable a large stroke with 7.79 mm/sec with 10kHz and 10V.

  • In implementing a robust automatic target recognition(ATR) system with synthetic aperture radar(SAR) imagery, one of the most important issues is accurate classification of target variants, which are the same targets with different serial numbers, configurations and versions, etc. In this paper, a deep learning network with channel attention modules is proposed to cope with the recognition problem for target variants based on the previous research findings that the channel attention mechanism selectively emphasizes the useful features for target recognition. Different from other existing attention methods, this paper employs the channel attention modules without dimensionality reduction along the channel direction from which direct correspondence between feature map channels can be preserved and the features valuable for recognizing SAR target variants can be effectively derived. Experiments with the public benchmark dataset demonstrate that the proposed scheme is superior to the network with other existing channel attention modules.

  • Face tracking is to estimate the motion of a non-rigid face together with a rigid head in 3D, and plays important roles in higher levels such as face/facial expression/emotion recognition. In this paper, we propose an AAM-based face tracking algorithm. AAM has been widely used to segment and track deformable objects, but there are still many difficulties. Particularly, it often tends to diverge or converge into local minima when a target object is self-occluded, partially or completely occluded. To address this problem, we utilize the scale invariant feature transform (SIFT). SIFT is an effective method for self and partial occlusion because it is able to find correspondence between feature points under partial loss. And it enables an AAM to continue to track without re-initialization in complete occlusions thanks to the good performance of global matching. We also register and use the SIFT features extracted from multi-view face images during tracking to effectively track a face across large pose changes. Our proposed algorithm is validated by comparing other algorithms under the above 3 kinds of occlusions.
