Abstract: The present disclosure discloses an image processing method, an apparatus, an electronic device, and a storage medium. The method includes: determining at least one target limb key point of a current video frame; determining at least one current effect key point according to the at least one target limb key point and historical limb key points of at least one historical video frame adjacent to the current video frame; obtaining historical effect key points of the at least one historical video frame according to preset effect parameters, and determining, according to the at least one current effect key point and the historical effect key points, at least one group of target effects matching the preset effect parameters; and determining a target video frame corresponding to the current video frame based on the at least one group of target effects.

Abstract: A 3D printing conveying platform includes a conveyor belt and a drive assembly driving the conveyor belt in a first direction, a base, a follower assembly and a movable component. The drive assembly is mounted to the base. The follower assembly is disposed opposite the drive assembly in the first direction, the conveyor belt is drive connected to the follower assembly. The movable component includes a first movable member and a second movable member connected to each other, the first movable member is connected to the follower assembly, the second movable member is movably disposed between the first movable member and the base and connected to the first movable member and the base, such that the follower assembly is capable of oscillating in a second direction relative to the base. The present application also provides a 3D printer.

Abstract: The present disclosure provides a method and an apparatus for processing a video image, an electronic device, and a non-transitory computer readable storage medium. The method for processing a video image includes: determining attribute information of an object to be processed in a video frame to be processed; determining datum display information of the object based on the attribute information of the object; and adjusting, based on the datum display information, target display information of a mounted material in the video frame to be processed, to obtain a processed video frame corresponding to the video frame to be processed.

Abstract: A 3D printer extrusion structure, comprising: a housing; a motor provided on the housing; an active extrusion gear provided in the housing and connected to the motor; an adjusting support rotatably connected inside the housing; a driven extrusion gear provided at one end of the adjusting support and rotatably connected to the adjusting support; and an elastic member, the elastic member being connected to an other end of the adjusting support to enable the end of the adjusting support provided with the driven extrusion gear to approach the active extrusion gear, so that the driven extrusion gear works in conjunction with the active extrusion gear to extrude material, wherein the end of the adjusting support provided with the driven extrusion gear extends to the outside of the housing.

Abstract: Provided is a strain sensor including a fixing plate and a strain gauge. The fixing plate includes a first supporting part and a second supporting part flexibly connected to the first supporting part. The present application is advantageous in that a strain sensor with a simple structure, high reliability and high sensitivity is provided. The horizontal status of a contact surface may be detected by a little amount of deformation, and the flexible fixing plate can provide a buffer for the equipment to prevent damages due to direct impact.
