Problems solved by technology

In this case, when both the vehicle and the object of interest may be moving relative to the environment, it may be difficult for the vehicle to identify individual objects in its vicinity simply by examining a single camera frame
Such object detection can be especially difficult where there may be a large number of candidate objects within the camera's field of view

Embodiment Construction

[0015] The subject matter described herein relates generally to improved systems and methods for detecting objects from the perspective of a mobile platform. As a non-limiting example, the systems and methods described herein may be applied to more accurately and reliably detect pedestrians near mobile platforms such as robotic devices, aircraft, motor vehicles, rotorcraft, trains, ships, and the like.

[0016] The following detailed description is merely exemplary in nature and not intended to limit application and use. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. As used herein, the term "module" refers to an application-specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or grouped) and memory, a combined logic circuits, and / or other suitable components that provide the described functionali...

Abstract

Systems and methods for detecting objects from mobile platforms are provided. The method includes receiving first and second image frames from a camera coupled to the mobile platform, wherein the second image frame is temporally subsequent to the first image frame. Within the first image frame, a first object is defined to characterize the position of the object detected in the first image frame. A first score associated with the first goal and a second score associated with the second goal are determined, and a first predicted goal is determined based on a tracking process applied to the first goal. A third score associated with the first predicted target is determined. The method determines a merged target corresponding to the second target when the second score is greater than a third score and when a measure of proximity between the second target and the first predicted target is greater than a threshold.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Provisional Patent Application No. 62 / 067,106, filed October 22, 2014, the contents of which are incorporated herein by reference. technical field [0003] The technical field relates generally to object detection, and more particularly to systems and methods for video-based object detection from mobile platforms. Background technique [0004] It is often desirable to detect and track objects from the viewpoint of the mobile platform. For example, advanced motor vehicles may contain one or more cameras that are capable of observing the vehicle's environment, including any objects (such as pedestrians) within the camera's field of view. In this case, when both the vehicle and the object of interest may be moving relative to the environment, it may be difficult for the vehicle to identify individual objects in its vicinity simply by examining a single camera frame. Such object detect...
