Abstract: Example systems and methods for data augmentation for occlusion handling in feature extraction are provided. An example method involves accessing a geospatial image depicting an occludable landcover feature; augmenting the geospatial image with a simulated occluding landcover feature to generate an occluding feature-augmented geospatial image, wherein the simulated occluding landcover feature partially occludes the occludable landcover feature as depicted in the geospatial image; and training a machine learning model, using the occluding feature-augmented geospatial image, to extract geometric representations of occludable landcover features as depicted in geospatial imagery.

Abstract: The disclosure provides a material pipe and feeding system. The material pipe comprises: a rotation shaft that is provided with an outer thread on an outer peripheral surface; a housing that is covered around an exterior of the rotation shaft and that is provided with an inner thread and a recess spaced from the inner thread on an inner peripheral surface; a fixing member having an axially extending through hole, the fixing member being provided with an outer thread on an outer peripheral surface thereof matching the inner thread of the housing, and the through hole being provided with an inner thread on a hole wall thereof matching the outer thread of the rotation shaft; and a positioning assembly comprising an engaging member detachably disposed in the recess at one end and fixed to the fixing member at the other end.
