A preparation method of a polytetrafluoroethylene (PTFE)-based membrane for preventing and removing ices covering wind turbine blades is provided and the method comprises: preparing a membrane into a PTFE rod material with polymerized monomers by using monomer polymerization methods such as blending, pre-compressing and pushing; making the membrane into a PTFE-based homogeneous membrane with micropores and nano and micron scale concave-convex geometrical ultra-structure morphologies under the condition that the membrane is cracked to generate a laminar exfoliated fabric-like structure in the hot calendaring process of the PTFE rod material by using a hot calendaring and fusion polymerization method; and applying the PTFE-based homogeneous membrane to blades of a large wind turbine in operation.

A method and an apparatus for detecting an abnormal situation are disclosed. The method includes recognizing whether a detection target exists in a captured image; generating, based on the captured image, a three-dimensional point cloud of the detection target in the captured image, when the detection target exists; obtaining, based on the generated three-dimensional point cloud, one or more current posture features of the detection target; and determining, based on the current posture features and one or more predetermined posture feature standards, whether the abnormal situation exists, the posture feature standards being previously determined based on one or more common features when the detection target performs a plurality of abnormal actions.

A method and an apparatus for separating objects are disclosed. The method includes obtaining a depth image including a plurality of objects; obtaining a two-dimensional image including the objects; performing pixel-clustering using depth values of pixels in the depth image and pixel values of pixels in the two-dimensional image to obtain a plurality of sub-regions; performing region-clustering for the sub-regions to obtain a clustering result as an object separation result; and outputting the object separation result.
