Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for estimating a 3-D pose of an object of interest from image and point cloud data. In one aspect, a method includes obtaining an image of an environment; obtaining a point cloud of a three-dimensional region of the environment; generating a fused representation of the image and the point cloud; and processing the fused representation using a pose estimation neural network and in accordance with current values of a plurality of pose estimation network parameters to generate a pose estimation network output that specifies, for each of multiple keypoints, a respective estimated position in the three-dimensional region of the environment.

Abstract: The present disclosure provides a pixel unit, a display substrate, a display panel, and a display device. The pixel unit includes a slit electrode having a slit. The pixel unit includes at least two sub-pixels corresponding to different colors, each of the pixels includes n domain areas arranged along a first direction, n is a positive integer greater than or equal to 2, extension directions of the slits of the slit electrodes in any two adjacent domain areas in the n domain areas of the pixel unit are different, an acute angle between an extension direction of the slit in each domain area and a second direction is a predetermined angle, the predetermined angle is greater than or equal to 30° and less than 45°, and the second direction intersects with the first direction.

Abstract: The present disclosure provides a display panel, a manufacturing method and a display device. The display panel includes a first substrate, a second substrate and liquid crystal molecules. Each sub-pixel includes n domains, and at least two of the n domains are arranged in a first direction. An alignment film is arranged on one or both of the first substrate and the second substrate and provided with alignment directions, and/or slit electrodes each with a slit are arranged on one or both of the first substrate and the second substrate. The alignment directions in at least two adjacent domains in the n domains are different and/or extension directions of the slits in any two adjacent domains are different, so that the liquid crystal molecules in different domains are provided with different pretilt angles.
