First, SIFT feature are extracted from both images and the matching points are found. RANSAC method is applied to eliminate wrong matching points. Second, two stereo images are rectified and generated disparity mapping. Finally, the depth mapping and 3D information of each pixel are derived. This method is applied to reconstruct and measure the true object in indoor environment.","PeriodicalId":20466,"journal":{"name":"Proceedings of 2011 6th International Forum on Strategic Technology","volume":"1 1","pages":"738-742"},"PeriodicalIF":0.0,"publicationDate":"2011-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75945139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to meet the requirement, a complete signal conditioning circuit is designed and analysised in this paper. Firstly, Biological signals can be reflected in form of electrical signals by impendance sensor. Secondly, In order to detect weak signals in noises. I have designed Preamplifier circuit, Low-pass filter amplifier circuit, Modulate and Demodulate Circuits. At last, Mathematical models are established after comparison test and the theory analysis. Experimental results show that the signal conditioning circuit can effectively improve SNR, and the sensor output signal can be amplified between 0 and 5V.

In order to factually simulate the influence of friction on AC servo system, three-loop nonlinear model of industry AC servo motor including measured Stribeck friction disturbance factors is established. The control performance of position loop is simulated and studied by adopting traditional PID and fuzzy PID. The results show that Stribeck friction can lead to “flat top” of position tracking and “dead zone” of speed tracking adopting traditional PID, while fuzzy PID decreases the influence of friction on servo system performance and improves tracking precision and robust performance of the system.","PeriodicalId":20466,"journal":{"name":"Proceedings of 2011 6th International Forum on Strategic Technology","volume":"52 1","pages":"706-711"},"PeriodicalIF":0.0,"publicationDate":"2011-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82030109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The one dimensional and self-consistent fluid model of gas discharge was established which is composed by the electron and ion continuity and momentum transfer equations, and the nonlinear equations were solved by using the SG algorithm. The results showed that the short gap discharge of electrode coverage behaves the typical nonlinear characteristic such as Hopf bifurcation and Chaos. Two ways leading to Chaos have been found by changing discharge conditions, one is quasi-period and the other is double-period.
