Abstract:
(EN) A positioning system and a building method therefor. The positioning system comprises: base stations (200) and a movable positioning device (300); there are at least four base stations, and locations of any three base stations (200) among the at least four base stations are non-collinear; each base station (200) can acquire first distance information between this base station (200) and other base stations (200); the positioning device (300) is disposed at least two calibration locations and can acquire second distance information between each calibration location and any three base stations (200); the base stations (200) establish a relative coordinate system and calculate, according to the first distance information between the base stations (200), the second distance information between the calibration locations and any three base stations (200), and absolute coordinates of the calibration locations in a preset fixed coordinate system, transformation parameters between the relative coordinate system and the fixed coordinate system. By acquiring the absolute coordinates of multiple calibration locations of which absolute coordinates are easy to be measured, a building process is simplified, and thus the building time is shortened.
(FR) L'invention concerne un système de positionnement et un procédé de construction associé. Le système de positionnement comprend : des stations de base (200) et un dispositif de positionnement mobile (300). Il existe au moins quatre stations de base, et les emplacements de trois stations de base (200) quelconques parmi lesdites quatre stations de base sont non colinéaires. Chaque station de base (200) peut acquérir des premières informations de distance entre cette station de base (200) et d'autres stations de base (200). Le dispositif de positionnement (300) est disposé au niveau d'au moins deux emplacements d'étalonnage et peut acquérir des deuxièmes informations de distance entre chaque emplacement d'étalonnage et les trois stations de base (200) quelconques. Les stations de base (200) établissent un système de coordonnées relatives et calculent, conformément aux premières informations de distance entre les stations de base (200), les deuxièmes informations de distance entre les emplacements d'étalonnage et les trois stations de base quelconques (200), et des coordonnées absolues des emplacements d'étalonnage dans un système de coordonnées fixes prédéfini, des paramètres de transformation entre le système de coordonnées relatives et le système de coordonnées fixes. En acquérant les coordonnées absolues de multiples emplacements d'étalonnage dont les coordonnées absolues sont faciles à mesurer, un processus de construction est simplifié et ainsi le temps de construction est raccourci.
(ZH) 一种定位系统及其搭建方法,该定位系统包括:基站(200)及可移动设置的定位设备(300),基站至少四个,至少四个基站中任意三个基站(200)的位置不共线;每个基站(200)能够获取其与其他基站(200)之间的第一距离信息;定位设备(300)被设置在至少两个标定位置,能够获取各标定位置与其中任意三个基站(200)之间的第二距离信息;基站(200)建立相对坐标系,并根据各基站(200)之间的第一距离信息、各标定位置与任意三个基站(200)之间的第二距离信息以及各标定位置在预设的固定坐标系下的绝对坐标,计算相对坐标系和固定坐标系之间的变换参数。通过获取多个易于测量绝对坐标的标定位置的绝对坐标,简化架设流程,从而缩短架设时间。
