  • Patent number: 10873702
    Abstract: Embodiments include devices and methods for adaptive image processing in an unmanned autonomous vehicle (UAV). In various embodiments, an image sensor may capture an image, while a processor of the UAV obtains attitude information from one or more attitude sensors. Such information may include the relative attitude of the UAV and changes in attitude. The processor of the UAV may determine a UAV motion mode based, at least in part, on the obtained attitude information. The UAV motion mode may result in the modification of yaw correction parameters. The processor of the UAV may further execute yaw filtering on the image based, at least in part, on the determined motion mode.

  • Publication number: 20200241536
    Abstract: Various embodiments include processing devices and methods for relocation and reinitialization for a robotic device. Various embodiments may include concurrently relocating a second pose of the robotic device and reinitializing a third pose of the robotic device in response to failing to determine a first pose of the robotic device in the environment and determining that tracking of the robotic device is lost. Various embodiments may include pre-relocating a second pose of the robotic device in the environment in response to failing to determine the first pose of the robotic device in the environment and determining that tracking of the robotic device is lost, relocating a third pose of the robotic device in response to successfully pre-relocating the second pose of the robotic device, and reinitializing a fourth pose of the robotic device in response to unsuccessfully pre-relocating the second pose of the robotic device.

  • Publication number: 20200218279
    Abstract: Various embodiments include processing devices and methods for navigation of a robotic vehicle. Various embodiments may include a rearward-facing image sensor mounted such that its plane angle aligns with a navigation plane of the robotic vehicle. In various embodiments, the image sensor of the robotic vehicle may capture images and a processor of the robotic vehicle may execute simultaneous localization and mapping (SLAM) tracking using the captured images. Embodiments may include a processor of the robotic vehicle determining whether the robotic vehicle is approaching a barrier. If the robotic vehicle is approaching a barrier, the processor may determine whether a rotation angle of the image sensor of the robotic vehicle exceeds a rotation threshold. If the rotation angle exceeds the rotation threshold then the processor may determine whether SLAM tracking is stable; and reinitialize a pose of the robotic vehicle in response to determining that SLAM tracking is not stable.

  • Publication number: 20200167953
    Abstract: Various embodiments include processing devices and methods for initializing an image sensor of a robotic vehicle. In some embodiments, a processor of the robotic vehicle may extract first features from a captured image of the target image, may extract second features from a predefined image pyramid of the target image, may match first features and second features, and may estimate an image sensor pose based on matched features and known dimensions of the target image. In some embodiments, the processor may estimate an image or to image sensor pose based on matched features and a translation and/or rotation of the robotic vehicle. In some embodiments, the processor may determine a coordinate system for the robotic vehicle based on one or more image sensor poses.

  • Publication number: 20200117210
    Abstract: Various embodiments include processing devices and methods for classifying areas close to the robotic vehicle as feature-rich or feature-poor based, at least in part, on identified environmental features. A processor may select a target position based, at least in part, on the classified areas and the path costs, and initiate movement of the robotic vehicle toward the selected target position. Occasionally during transition of the robotic vehicle, the processor may determine whether the robotic vehicle has reached the target position and in response to determining that the robotic vehicle has not reached the target position, the processor may adjust the robotic vehicle's trajectory. For example, the processor may perform localization of the robotic vehicle based, at least in part, on the classified areas and may also modify a path of the robotic vehicle to the target position based, at least in part, on the localization and the classified areas.
