PRODUCING DATA DESCRIBING TARGET MEASUREMENTS

摘要

Methods and systems for producing data describing target measurements using a processor (102) in a system (100) having at least one on-board sensor (106) on a vehicle. The method includes obtaining data from an on-board sensor (106), obtaining data from a sensor (108) off-board the vehicle, activation approximating (312) a target alignment error between the on-board and off-board sensor data, receiving target alignment error data in respect of at least one other sensor set comprising at least two sensors, estimating (316) a bias using the received target alignment error data and correcting the approximated target alignment error using the bias, and performing (320) a data fusion process on the obtained off-board sensor data and the obtained on-board sensor data using the approximated target alignment error to produce target measurement data.

1. A method of producing on a vehicle data describing target measurements of one or more target positions using a processor in a system having at least one sensor on-board the vehicle, the method including:
obtaining first on-board sensor data representative of a target from said on-board sensor; obtaining from a sensor of an off-board vehicle co-operator first off-board sensor data representative of said target; approximating a target alignment error between said first on-board sensor data representative of said target and said first off-board sensor data representative of said target; subsequently obtaining second on-board sensor data representative of said target from said on-board sensor and obtaining second off-board sensor data representative of said target from said off-board sensor; receiving alignment error data derived from said second on-board and off-board sensor data; estimating a bias using said received alignment error data and correcting said approximated target alignment error using said bias; and performing a data fusion process on the obtained first off-board sensor data and the obtained first on-board sensor data using said corrected approximated target alignment error to produce a measure of said target position.
