Abstract
A moving object localization system includes: a sensor that detects a moving object and measures positional information of the moving object; and a server that collects measured information from the sensor and calculates a position of moving object.
Claims13
A moving object localization system comprising:
- a sensor that detects a moving object and measures positional information of the moving object;
- and
- a server that collects measured information from the sensor and calculates a position of moving object.
A moving object localization method, comprising:
- taking pictures at certain intervals by two or more sensors having fixed positions;
- detecting a moving object by comparing each of the pictures with an existing background by each of the sensors and calculating an angle of deviation of the moving object from a center of each of the pictures when detecting the moving object;
- and
- aggregating the calculated angle of each of the sensors in a server and estimating a position of the moving object.
1 more element
A method of estimating a position of a moving object by triangulation, comprising:
- projecting the position of the moving object measured by two sensors on a horizontal plane in two dimensions;
- and
- calculating an altitude using an elevation angle of the position of the moving object.
