Abstract: Embodiments of this disclosure relate to the multimedia processing field, and provide a video frame interpolation method, apparatus, and a device. In the video frame interpolation method in this disclosure, a first image at first time, a second image at second time, and sensor data captured by a dynamic vision sensor apparatus are obtained, and the sensor data includes dynamic event data between the first time and the second time. At least one target image is determined based on the first image, the second image, and the sensor data, where the at least one target image is an image corresponding to at least one target time between the first time and the second time. The dynamic event data is used to help compensate for motion information missing from existing image data. This implements accurate prediction of an intermediate image, and improves image prediction effect.

Abstract: An optical display system and an electronics device are disclosed. The optical display system comprises: a display, which generating image light of a first polarization; a partial reflector, which transmits the image light without changing its polarization and reflects the image light with its polarization being changed to a second polarization; a first optic unit, placed after the partial reflector, which includes at least one refractive lens for chromatic aberration correction; and a reflection-type Pancharatnam-Berry lens, which is placed after the first optic unit and works in the Bragg regime, and which reflects the image light of the first polarization and transmits the image light of the second polarization.

Abstract: A gluing method of a filter cartridge includes: preparing a filter core and a filter frame; disposing them in a lower mold with the filter frame under the filter core; filling glue on top of the lower mold, extending the glue to a gluing segment of the filter frame and an outer surface of the filter core; pressing down an upper mold toward the lower mold to cut the glue into an inner glue segment and an outer glue segment. The inner glue segment is pressed in between the filter frame and the filter core, coated around the gluing segment to increase adhering area. Pressure from the upper mold enhances the adhering effect. The cutting removes surplus glue and the glue is formed into a desired shape, thus the method is quick, accurate and consistent.

Abstract: A track prediction method and device for an obstacle at a junction are provided. The method includes: acquiring environment information of a junction to be passed by a vehicle, and acquiring information on a visible obstacle in a sensible range of the vehicle, wherein the environment information comprises road information and information on a junction obstacle located in an area of the junction; combining the information on the junction obstacle with the information on the visible obstacle, and selecting information on a blind-zone obstacle in a blind zone of the vehicle at the junction; and predicting a moving track of an obstacle corresponding to the information on the blind-zone obstacle, according to the road information.

Abstract: A travelling track prediction method and device for a vehicle are provided. The method includes that: calculating a plurality of potential positions to which is to be reached by a target vehicle within a preset time within a sensible range of a main vehicle; selecting at least two positions from the plurality of potential positions as target positions; predicting a plurality of travelling tracks to each target position for the target vehicle based on travelling state information of the target vehicle; and selecting at least one travelling track from the plurality of travelling tracks as a prediction result of the target vehicle based on environment information around the target vehicle. According to the embodiments, the travelling track of the target vehicle around the main vehicle may be accurately predicted based on travelling state information and the environment information.

Abstract: A filter cartridge comprises a filter core, a filter frame, glue, and at least one sealing unit. The filter frame is mounted around an axial end of the filter core and has a frame body, an abutting segment, and a gluing segment. The abutting segment axially protrudes from and annularly extends along an edge of one of two axial end openings. The gluing segment axially protrudes from and annularly extends around the abutting segment, and surrounds the filter core. The glue is coated on and is wrapped around the gluing segment, extends into a position between the gluing segment and the filter core, and attaches to an inner gluing surface of the gluing segment, an outer gluing surface of the gluing segment, and an outer surface of the filter core. Therefore, the adhering area between the glue and the filter frame is effectively increased.
