Title
(EN) METHOD TO DETERMINE A PRESENT POSITION OF AN OBJECT, POSITIONING SYSTEM, TRACKER AND COMPUTER PROGRAM
(ZH) 确定对象当前位置的方法、定位系统、跟踪器和计算机程序
Abstract
(EN) A method (100) to determine a present position (122) of an object (600). The method (100) comprises using (102) an optical positioning system (104) to determine a first preliminary position (112) andusing (106) a radio-based positioning system (108) to determine a second preliminary position (114), determining (110) a supposed position (116) on the basis of one of the preliminary positions (112,114) and combining (108) the supposed position (116) with a previous position (212) of the object to determine the present position (122) of the object, if the supposed position (116) is based on a different positioning system (104, 108) than a previous supposed position (116'). A positioning system (500) with combined optical and a radio-based determination of a position of a tracker (600) and atracker (600) with an active light source (608).
(ZH) 一种确定对象(600)的当前位置(122)的方法(100)。该方法(100)包括:使用(102)光学定位系统(104)来确定第一初步位置(112),并使用(106)基于无线电的定位系统(108)来确定第二初步位置(114),基于初步位置(112、114)中的一者确定(110)假定位置(116);以及如果该假定位置(116)基于与先前假定位置(116')不同的定位系统(104、108),则将假定位置(116)与对象的先前位置(212)组合(108)以确定对象的当前位置(122)。一种具有跟踪器(600)的位置的组合的光学确定和基于无线电的确定的定位系统(500)以及具有有源光源(608)的跟踪器(600)。
