This results in lower measurement precision and accuracy of the system. Generally, the stabilization method based on hardware and software was applied. It is difficult to solve the problem about Spectrum drift caused by multiple factors. To slove the nonlinear problems caused by interference source, Multi-sensor Data Fusion Technique is adopt to design the intelligent nuclear detector with the Self-compensation Technique.

In order to fulfill precise measurement with limitation of vision field, diversity and severe surface condition of miniature parts, a two-layered architecture with operator interaction is proposed. These two layers specify for user and developer of the assembly application respectively. Based on part's feature, the former adjusts vision parameters with the interface of dynamic illumination control and the later develops reasonable feature extraction strategy for measurement of part's position and orientation with an image processing tool. With general image processing algorithms, it can not only be applied by itself, but also be integrated into an assembly system to facilitate developer to adjust image processing strategy. This operator interaction function can improve the accuracy of recognizing and locating part, promote the success ratio of product assembly and shorter the period of software development as well.","PeriodicalId":321964,"journal":{"name":"IEEE 2011 10th International Conference on Electronic Measurement & Instruments","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126180482","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 general, magnetometers fixed on the vehicles are prone to be disturbed by the magnetic field of the vehicles. In order to improve the navigation precision, magnetic field of vehicles must be compensated. In this paper, a new compensation method is proposed. Through analysis of the relationships between measurements and truth of geomagnetic field, a new measurement model using vector measurements and scalar truth is derived, and an algorithm based on UKF is used to evaluate the unknown parameters of the model. Finally computer simulation is carried out to assess the validity of the method.

Time delay between channels of high-speed data acquisition system is an important time parameter to estimate and adjust. In high-speed data acquisition system, the ADC data output time is not fixed, and may lead to the delay time of each acquisition channel generated. In order to solve this problem, an algorithm based on TDC is proposed to estimate and calibrate the delay. The algorithm is based on the truth that the sampled data and the data synchronized clock of ADC are synchronized. So phase relationship of the data synchronized clocks can represent the delay between channels. Time-stretched Time-Digital-Converter (TDC) is used to measure the phase difference of the data synchronized clocks. The experiment result proves that the algorithm is faster than four-parameter sine wave fitting, and has a high accuracy up to 100ps.","PeriodicalId":321964,"journal":{"name":"IEEE 2011 10th International Conference on Electronic Measurement & Instruments","volume":"6 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116116889","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}
