Accurate information about depth and posture of the three-dimensional object can be obtained with a pyramid model positioning. The color of four lateral sides and a displacing bottom surface of a pyramid object model is white-black, the pyramid object model contains twelve straight lines, and the pyramid object model is displaced while the square bottom surface rotating 45 degree around the axle center. A positioning algorithm is designed combined with the model. As for any three straight lines on the pyramid object model which intersect at two points(wherein, two points of intersection has different distance with a camera photocenter), a positioning mathematic model can be established according to angle information between the straight lines and length information of the straight line. The model can conduct solving combined with step acceleration method based on geometric significance. The utility model has the advantages of easy picture processing, strong anti-shading capability, free line-selection, high positioning precision, simple positioning algorithm and strong timeliness. description.patentprioritydata CN20062153561U PCT Attributes 否 Application Date 2006-12-08 2008-03-19 Date Available 2008-03-19 Application Number CN200620153561.6 Open (Notice) Number CN201037936Y Language 中文 Contribution Rank 1 Document Type 专利 Identifier http://ir.sia.cn/handle/173321/13472 Collection 光电信息技术研究室 Affiliation 中国科学院沈阳自动化研究所 Recommended CitationGB/T 7714 朱枫,秦丽娟,郝颖明,等. 一种基于直线的目标模型[P]. 2008-03-19.
