    Patent number: 11481982
    Abstract: Disclosed are a system, apparatus, and method for in-situ creation of planar natural feature targets. In one embodiment, a planar target is initialized from a single first reference image one or more subsequent images are processed. In one embodiment, the planar target is tracked in six degrees of freedom upon the processing of the one or more subsequent images and a second reference image is selected from the processed one or more subsequent images. In one embodiment, upon selecting the second reference image the planar target is refined to a more accurate planar target.

  • DIRT DETECTION METHOD FOR CLEANING DEVICE AND DIRT COLLECTING DEVICE
    Publication number: 20220296063
    Abstract: A dirt detection method includes the steps of: selecting a motor with a motor processor, and then using the motor to provide power to form a negative pressure to suck the dirt into the dirt collection device, the motor processor sending the motor's operating signal to the detection processor that has written therein a threshold range for detection, and then comparing the threshold range with the operating signal from the motor processor. The invention is based on the motor as the power source of negative pressure, and the dirt collection device has good collection effect and sealing. Based on the equipment characteristics of the motor in the negative pressure system, the degree of dirt in the dirt collection device is detected by detecting the operating signal of the motor.

  • Lightning strike probability-based coordinated power control method for energy storage system and load
    Patent number: 11444476
    Abstract: A lightning strike probability-based coordinated power control method for an energy storage system and a load adjusts output power of an energy storage system and a regulatable load based on a real-time predicted lightning strike probability. This reduces a correlation between a power grid in a lightning region and an external power grid, minimizes impact of a lightning strike if any on the external power grid, and decreases an economic loss due to the lightning strike in the lightning region. The present disclosure establishes a relationship between the output power of the energy storage system, the regulated power of the regulatable load, and a lightning strike probability in a same region, and then regulates the power of the energy storage system and the regulatable load in real time based on the lightning strike probability.

  • 3D RECONSTRUCTION USING WIDE-ANGLE IMAGING DEVICES
    Publication number: 20220230351
    Abstract: The pose of a wide-angle image is determined by dewarping regions of the wide-angle image, determining estimated poses of the dewarped regions of the wide-angle image and deriving a pose of the wide-angle image from the estimated poses of the of the dewarped regions. The estimated poses of the dewarped regions may be determined by comparing features in the dewarped regions with features in prior dewarped regions from one or more prior wide-angle images, as well as by comparing features in the dewarped regions with features in a point cloud.

  • LOCALIZING AN AUGMENTED REALITY DEVICE
    Publication number: 20220156976
    Abstract: Determining the position and orientation (or “pose”) of an augmented reality device includes capturing an image of a scene having a number of features and extracting descriptors of features of the scene represented in the image. The descriptors are matched to landmarks in a 3D model of the scene to generate sets of matches between the descriptors and the landmarks. Estimated poses are determined from at least some of the sets of matches between the descriptors and the landmarks. Estimated poses having deviations from an observed location measurement that are greater than a threshold value may be eliminated. Features used in the determination of estimated poses may also be weighted by the inverse of the distance between the feature and the device, so that closer features are accorded more weight.
