Problems solved by technology
The hardware second pulse signal or the software system time can ensure that the data collected by multiple sensors is in the same time system, but after some sensors collect data and mark the time stamp, they will perform some time-consuming preprocessing before they can participate in data fusion, that is, , there is often a time delay between the time when some sensor data reaches the data fusion stage and the time of collection, and the time delay of different sensors is different. Therefore, time alignment is required before data fusion

Embodiment Construction
[0030] Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
[0031] The positioning system in the intelligent driving vehicle is used to determine the current vehicle position, attitude, speed, etc., and is an indispensable part of the intelligent driving system. Due to the limitations of sensor performance, positioning with a single sensor cannot meet the performance requirements of intelligent driving vehicles. Therefore, multi...

The invention provides a fusion positioning method and device, electronic equipment, a non-instantaneous computer readable storage medium and a computer program product, and particular, relates to the field of intelligent driving. The method comprises the steps: receiving data of a plurality of sensors; when a fusion positioning signal is obtained, determining a fusion estimation moment according to a current moment and a preset delay time; determining a plurality of pieces of target data from the data of the plurality of sensors according to the fusion estimation moment; and performing data fusion on the plurality of pieces of target data to obtain fused positioning information. According to the invention, time alignment of fusion positioning is realized.
Description
technical field [0001] Embodiments of the present disclosure relate to the technical field of artificial intelligence, and in particular to a fusion positioning method, device, electronic equipment, non-transitory computer-readable storage medium, and computer program product, which can be used in the field of intelligent driving. Background technique [0002] The positioning system in the intelligent driving vehicle is used to determine the current vehicle position, attitude, speed, etc., and is an indispensable part of the intelligent driving system. Due to the limitations of sensor performance, positioning with a single sensor cannot meet the performance requirements of intelligent driving vehicles. Therefore, multi-sensor fusion positioning is usually used to fuse data from multiple sensors to finally obtain positioning information. [0003] In order to ensure real-time and accurate positioning information and low consumption of system resources, the backend of multi-sen...
