On account of a good many of factors, such as the uneven ends of billet, the rusty billets, the non-standard printed characters and so on, the irregular characters at ends of steel billet may be connected and broken. Improper segmentation of connected and broken characters will lead the characters distorted directly and then impact on the recognition results. In view of these complex factors, a segmentation algorithm based on self-adaptability decision is proposed to improve the segmentation self-adaptability in this paper. The segmentation experimental results show that the proposed algorithm divides the billet characters in the complex scene accurately and improves the self-adaptability of character segmentation.","PeriodicalId":393655,"journal":{"name":"International Conference on Digital Manufacturing and Automation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123877448","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 validate and improve the geometric accuracy of ADS40 which is a kind of three-tine-scanner photogrammetric airborne sensor, a geometric calibration method is developed in this paper using a test field. According to ADS40, schemes and theories of the geometric calibration method are introduced, a calibration model which is based on self-calibration bundle adjustment is proposed. The effects of factors, such as flight strip arrangement, amount of ground control point, and additional parameters of the calibration model and so on, influencing the accuracy of ADS40 are analyzed through experiments. Consequently, experimental results showed that the self-calibration model can highly improve the geometric accuracy of ADS40.
