Abstract

The invention discloses a target positioning method and system, an unmanned aerial vehicle and a storage medium. The method comprises the steps of acquiring direction data of multiple targets measuredby the same unmanned aerial vehicle at a current sampling moment; and processing the direction data of each target at the current sampling moment by using a three-dimensional Pseudo-linear Kalman filter algorithm, and thus acquiring the state information of each target at the current sampling moment. According to the mode above, the multiple targets can be positioned by the same unmanned aerial vehicle at the same time, and the multiple targets can be more accurately positioned.

Description

technical field [0001] The present application relates to the field of unmanned aerial vehicles, in particular to a method and system for target positioning, an unmanned aerial vehicle and a storage medium. Background technique [0002] Compared with satellite positioning technology, drones have more advantages in the accuracy and speed of searching targets. Therefore, drones have been widely used in target tracking or searching in various fields in recent years. However, when performing search tasks on multiple targets, since the search range is often very large, in the prior art, multiple drones are often used to disperse operations in order to quickly lock the target. However, since scattered UAVs are difficult to cooperate with, and will also limit the accuracy of the search and increase the cost input, a solution that can solve the current technical problems is needed. Contents of the invention [0003] The technical problem mainly solved by this application is to pr...
