Abstract

The invention proposes a synchronization method and apparatus, wherein based on a measuring time (110, 210) and the value of at least one quantity of the at least one sensor object, the at least one sensor object is determined at at least one of the base times (t_k−1, t_k, t_k+1).

Claims

1. A method for synchronizing sensor data of a sensor object, which are generated by at least one sensor (100, 200, 300) at a measuring time (110, 210), to a common time base comprised of a number of base times (t_k−

1, t_k, t_k+1), wherein based on the measuring time (110, 210) and the value of at least one quantity of the at least one sensor object, the at least one sensor object is determined at at least one of the base times (t<sub>k−

1</sub>, t_k, t_k+1).

2. The method according to claim 1, characterized in that the measuring time (110, 210) lies chronologically before or chronologically after the base time (t_k−

1, t_k, t_k+1).

3. The method according to one of the preceding claims, characterized in that the at least one quantity is a measured or calculated quantity.

4. An apparatus for synchronizing sensor data for executing a method according to one of the preceding claims.
