Abstract: An information processing method includes: three-dimensional (3D) point information of a 3D point cloud is obtained; a two-dimensional (2D) point cloud image from projection of the 3D point cloud on a horizontal plane is generated based on the 3D point information; and projection coordinates of 3D points comprised in the 3D point cloud in a reference coordinate system of a reference plane graph are determined based on a consistency degree that the 2D point cloud image has with the reference plane graph, where the reference plane graph is used for representing a projection graph with reference coordinates that is obtained through the projection of a target object on the horizontal plane, and the 3D point cloud is used for representing 3D space information of the target object.

Abstract: A device comprises a substrate and an IC die, which may be a photonic IC. The substrate comprises a first surface, a second surface opposite the first surface, an optical waveguide integral with the substrate, and a hole extending from the first surface to the second surface. The hole comprises a first sidewall. The optical waveguide is between the first surface and the second surface, parallel to the first surface, and comprises a first end which extends to the first sidewall. The IC die is within the hole and comprises a second sidewall and an optical port at the second sidewall. The second sidewall is proximate to the first sidewall and the first end of the optical waveguide is proximate to and aligned with the optical port. The substrate may include a recess to receive another device comprising a socket.

Abstract: A joint for a swimming pool frame, and a swimming pool including the joint are provided. The joint includes a joint body including a leg pipe holder configured to have a leg pipe of the swimming pool frame inserted into the leg pipe holder. The joint also includes a side pipe holder configured to have a side pipe of the swimming pool frame inserted in the side pipe holder. A locking hole is formed through the side pipe holder. The joint body also includes a locking part including a locking pin configured to extend through the locking hole and through a corresponding connecting hole in the side pipe, thereby holding the side pipe to the side pipe holder.

Abstract: A device installation structure for detachable pet products, a pet leash, and a pet tethering rope may be provided. The structure may include a detachable device installation structure; an elastic hook, including an elastic extension portion mounted on the detachable device and extending outward; a first bending portion located at the end of the elastic extension portion and bent towards the direction close to the detachable device; a second bending portion located at the end of the first bending portion and bent towards the direction away from the detachable device.

Abstract: An adjustable pet collar, including: a flexible collar strap, one end of the flexible collar strap is a buckle end, and the other end is movable; a first fastener, a second fastener, and a second buckle. The flexible collar is provided with a buckle structure that matches the buckle end; the movable end of the flexible collar belt passes through the first buckle and the second buckle one after another and then is fixed to the first buckle. The flexible collar belt includes: one end as a buckle The buckle end and the other end are movably connected to the first movable section of the first fastener, movably connected to the second movable section between the first fastener, and the second fastener, and one end is the movable end fixed to the first fastener and the other end is movably connected to the third movable section of the second fastener.

Abstract: An integrated pet harness with a pet leash, including: a flexible back pad and a flexible chest pad, a pair of first connecting straps and a second connecting strap, oppositely arranged;: connecting to the flexible back pad and the telescopic traction rope on the pad, and the telescopic traction rope can be accommodated in the flexible back pad. The front end of the flexible back pad is provided with a pair of first extension parts extending to both sides; the rear end of the flexible back pad is provided with a pair of second extension parts extending to both sides. There are a pair of third extension parts extending to both sides respectively; a pair of first connecting strips are fixed to the front end of the flexible back pad, and two ends of the pair of first connecting strips are respectively passed through the pair of first extending parts.

Abstract: A dog rope leash with a storage function, including: a rope body, a handle on one end of the rope body, a clasp on the other end of the rope body, and a connection box mounted on the handle and/or rope body. The inside of the connection box has a storage cavity, and the surface of the connection box has an access port connected to the storage cavity. Garbage bags or other items in the storage cavity of the connecting box by designing the connection box on the dog rope leash, which is simple in structure and convenient in use.

Abstract: Visual localization method and related apparatus are disclosed. In the method, a first candidate image sequence is determined from image library, the image library being configured to construct electronic map, image frames in the first candidate image sequence being sequentially arranged according to degrees of matching with first image, and the first image being an image collected by a camera; an order of the image frames in the first candidate image sequence is adjusted according to target window to obtain second candidate image sequence, the target window being multiple successive image frames including target image frame and determined from the image library, the target image frame being an image matching with second image, which is collected by the camera before the first image is collected, in the image library; and target posture of the camera when the first image is collected is determined according to the second candidate image sequence.
