Problems solved by technology

However, this method calculates the estimated value of current information based on previous information and current information, so there is a hysteresis effect, and the future trend of the target cannot be predicted. When the target is maneuvering at high speed, the current estimate will have a large deviation from the real movement of the target. Poor real-time performance and accuracy

Abstract

The invention discloses a flight path updating method and a flight path updating device which are used for promoting the accuracy of data fusion and further accurately updating a flight path. The method comprises the following steps: acquiring sensor data obtained by measurement of M heterogeneous sensors, wherein M is an integer greater than or equal to 2; determining a first sensor, which has a time point the same as a fusion time point of the sensor data, among the M heterogeneous sensors; based on the fusion time point, obtaining sensor data with unified time from the sensor data; performing correlation on the sensor data with unified time, thereby obtaining correlated sensor data; when determining that the M heterogeneous sensors are correlated with a formed flight path of a flying apparatus based on the correlated sensor data, updating the flight path based on the correlated sensor data.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for updating a track. Background technique [0002] As the flight range of future flight equipment expands, the types and numbers of sensors continue to increase. In the process of establishing the flight path of flight equipment, the real-time requirements for information fusion are also getting higher and higher. Heterogeneous multi-sensor information fusion is the key to future information fusion development. Its correctness, reliability, stability, etc. have a crucial impact on the establishment of the track. For example, radar has better ranging performance, and infrared sensor has better angle measuring performance. These two sensors have different measurement dimensions, and the measurement data are sampled asynchronously. Therefore, it is necessary to fuse the data of these two heterogeneous sensors to obtain precise positioning information of the ...
