Title:
DATA PROCESSING METHOD AND DEVICE, AND MOVABLE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2021/081816
Kind Code:
A1
Abstract:
Provided in embodiments of the present invention are a data processing method and device, and a movable platform, the method comprising: acquiring multiple estimates of a motion state of a target object at a previous moment, the object comprising the target object; predicting according to the multiple estimates of the motion state of the target object at a previous moment so as to obtain multiple predicted estimates of the motion state of the target object at the current moment; acquiring one or more observations outputted by a sensor; determining the matching state between each predicted estimate and each observation, the matching state comprising a compatible state and an incompatible state; updating a corresponding predicted estimate according to an observation that the matching state is the compatible state; and determining the updated estimate and a predicted estimate of the matching state being the incompatible state as the multiple estimates of the motion state at the current moment. Thus, the robustness may be improved when determining an estimate of a motion state of a target at the current moment.
