Systems and methods for visual target tracking

Abstract

A method for controlling a movable object to track a target object may be provided. The method may comprise: determining a change in one or more features between a first image frame and a second imageframe, wherein the one or more features are associated with the target object, and wherein the first image frame and the second image frame are captured at different points in time; and adjusting a movement of the movable object based on the change in the one or more features between the first image frame and the second image frame.

Description

Background technique [0001] In some surveillance, reconnaissance, and exploration tasks for real-world applications, it may be necessary to detect and track moving target objects. A movable object carrying a payload (eg, an aircraft carrying a camera) can be used to track a target object using, for example, visual tracking methods. However, existing visual tracking methods often may not take into account the spatial arrangement of the vehicle and / or camera relative to the target. In some cases, one or more operators may have to manually select the target object to track and manually control the aircraft and / or cameras to track the moving target. This limited tracking capability may reduce the vehicle's usefulness in certain applications. Contents of the invention [0002] There is a need to improve existing methods for visual tracking of moving objects. Improved tracking capabilities may enable a movable object carrying an imaging device to accurately track a target even ...
