Method for determining the position of moving objects
First Claim
1. A method for determining the position of a moving object having a sensor, comprising:
- transmitting odometry data from the sensor to a calculation device, estimating, via the calculation device, an orientation and position of the object, wherein the calculation device comprises a filter, creating a diffusion matrix based on the estimated orientation and position taking into account environmental data, determining a contour line based on the diffusion matrix, determining distances between the position and the contour line for different orientations, calculating a probability density function based on the distances, and determining a current orientation and position of the object via the filter based on a previously determined probability density function.

Abstract
Method for determining the position of moving objects, wherein the object has a sensor or an apparatus for determining odometry data, having the steps of: transmitting the odometry data to a calculation device, estimating the location and position of the object with the aid of the calculation device, creating a diffusion matrix on the basis of the estimated location and position taking into account environmental data, determining a contour line on the basis of the diffusion matrix, determining the distances between the position and the contour line for different orientations, in particular each orientation, and calculating a probability density function on the basis of the distances determined.
