Abstract: A method for calibrating extrinsic parameters of surround-view cameras on a vehicle includes: determining extrinsic parameters of the first camera and the second camera; determining a first pose initial value, a second pose initial value, a third pose initial value, and a fourth pose initial value; determining extrinsic parameters of the third camera and fourth camera according to the extrinsic parameters of the first camera and second camera, the first pose initial value, the second pose initial value, the third pose initial value, and the fourth pose initial value. According to the visual odometer information of the first camera and the second camera, the extrinsic parameters of the first camera and second camera are first determined, and the extrinsic parameters of the third camera and fourth camera are then determined according to the extrinsic parameter of the first camera and the extrinsic parameter of the second camera.

Abstract: Provided are a terminal position assurance and a connector, which belong to the technical field of connectors. The terminal position assurance includes a positioning body, an upper-row snap, a limiting member, and a lower-row snap. The positioning body extends along a first direction. Two upper-row snaps are provided, fixedly connected to the positioning body separately, and disposed opposite to each other. The limiting member is connected to one side of the positioning body and extends along a second direction which is perpendicular to the first direction. Two lower-row snaps are provided, fixedly connected to the limiting member separately, and disposed opposite to each other.

Abstract: A conductive terminal includes a first fixing portion, a first mating portion, a second fixing portion and a second mating portion. The second mating portion and the first mating portion are arranged side by side along a first direction. The first mating portion includes a first elastic piece extending along a second direction. The first elastic piece includes a first elastic contact portion. The second mating portion includes a second elastic piece. The second elastic piece includes a second elastic contact portion. The first elastic contact portion extends along a first arc-shaped surface. The second elastic contact portion extends along a second arc-shaped surface. Protruding directions of the first arc-shaped surface and the second arc-shaped surface are opposite to each other along the first direction. An electrical connector and an electrical connector assembly having the conductive terminal are disclosed.

Abstract: The embodiments of the present utility model provide a spring leaf, a connection terminal, and an electrical connector, where the spring leaf is provided in a cylindrical housing in a winding manner, and extends outward from a first end to form hangers extending out of the housing. The spring leaf is hung on an end portion of the housing through the hangers, and then the hangers are fixed through an end cover arranged at the end portion of the housing. Thus, the first end of the spring leaf may be fixed through the hangers, and a second end of the spring leaf may move automatically. When a pin is inserted, the compressed spring leaf will not be dislocated, which ensures the contact reliability of the pin with the spring leaf.
