Abstract: A visual localization method and apparatus are provided. The method includes obtaining a captured first image, determining a first pose based on the first image and an aerial model, determining whether a ground model corresponding to the first pose exists in an aerial-ground model, and when the ground model corresponding to the first pose exists, determining a second pose based on the ground model. The aerial-ground model includes the aerial model and the ground model mapped to the aerial model, a coordinate system of the ground model is the same as a coordinate system of the aerial model, and localization accuracy of the second pose is higher than localization accuracy of the first pose. Performing fine visual localization based on the ground model can improve accuracy and a success rate of localization.

Abstract: An OFS in-band communication method and an OFS are disclosed. The method includes: receiving an LLDP data packet; creating a controller list entry or updating a controller list entry when it is determined, by using a role sub-field, that a sender type of the received LLDP data packet is OFC; acquiring a first-time TCP handshake packet used for establishing a TCP connection, and checking, according to a destination MAC and a destination IP that are carried in the TCP handshake packet, whether a corresponding controller list entry exists in a controller list; and if yes, updating a flow entry according to the MAC, the IP, and the in_port in the corresponding controller list entry in the controller list, so that an OFS can forward, by using a flow table, a packet to be sent to an OFC to the OFC.
