The evaluation depends greatly on a personal opinion and there can be large variations in assessments. The project has investigated the use of machine vision in several ways, to provide measures of fodder quality that will be objective and independent of the assessor. Growers will be able to quote a quality measure that buyers can trust. The research includes the possibility of discerning colour differences that are beyond the capability of the human eye, while still using equipment that is of relatively modest cost.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127561349","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}

It is usually quite difficult to detect this kind of signal in noncooperative and real-time occasions. Based on the autocorrelation detection algorithm, a combination method of frequency band-divided pre-filteting and power spectrum reprocessing, which can be used to implement the real-time detection of underwater acoustic DSSS-BPSK signal, is put forward in this paper. This method can also be used to the estimation of the pseudo-random code period and chip width, and no prior knowledge of the intercepted signals is necessarily required. With frequency pre-filtering, it can not only suppress the strong ocean noise effectively, but also make the real-time detection possible via the FFT algorithm. The results of computer simulation and practical experiment have both validated the feasibility and validity of this method.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114173701","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}

Considering the characteristic of PMLSM, an original method based on end side magnetic field of the PMLSM is proposed. The method detects the real-time value of the magnetic field utilizing at least two linear Hall sensors which are fixed on the mover along the direction of the linear motor. The digital filtering techniques are used to deal with the magnetic field data smoothly. A farther mathematical method is developed to interpolate the normalized sinusoidal curve for improving the resolution and the precision.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130164595","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}

A software programme combined both functions was developed in this article. Functions and procedures for calculating colorimetric parameters were written in terms of Commission Internationale de l'Eclairage (CIE) definitions and recommendations. The calculation of the dominant wavelength is optimized to accelerate the search speed and increase the resolution as precise as 0.1 nm. Arbitrary combinations of Gaussian formulas were adopted to design LED spectrum. With continuously designed spectra, the relationship between CRI and K can be intuitionisticly viewed and judged, so an optimal range for both high CRI and K can be easily determined.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"59 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120874335","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}
