Parallel positioning method for numerous discrete nodes

Номер: CN0102111875A
Принадлежит:

The invention discloses a parallel positioning method for numerous discrete nodes, comprising the following steps: (1) allocating one unique number for each discrete node; (2) calculating a positioning group number of each discrete node in a first-layer positioning process by each discrete node; (3) independently carrying out three-point method positioning by each positioning group in the first-layer positioning process to acquire the relative coordinates of positioning data of each positioning group; (4) pairing all the positioning groups in the first-layer positioning process, and integrating all the pairs to a second-layer positioning process so as to convert the coordinates of all points contained in each positioning group in the first-layer positioning process to the relative coordinate system of a certain positioning group in the integrated second-layer positioning process; and (5) repeating the step (4) till the coordinates of all the discrete nodes are integrated to the relative ...

Method for positioning region of discrete nodes without reference nodes

Номер: CN0102073030A
Принадлежит:

The invention discloses a method for positioning a region of discrete nodes without reference nodes, which comprises the steps of: 1, measuring the distance between the discrete nodes in an effective range; 2, selecting three discrete nodes in the discrete nodes in the effective range to be used as alternative discrete nodes forming a full triangle; 3, with the alternative discrete nodes of the full triangle as searching starting points, determining a main node, an X node and a turning node; 4, selecting discrete nodes except for the main node, the X node and the turning node, adding into a relative coordinate system formed by the full triangle; 5, correcting the discrete node position of the relative coordinate system formed by the full triangle; and 6, repeating from the step 4 to the step 5 until all the discrete nodes are added in the relative coordinate system based on the full triangle to complete the positioning process. The invention has the advantages of small operation amount ...
