Abstract: In a rectangular region detection mechanism, a to-be-processed image information is received, where the to-be-processed image information comprises at least two images, and where the at least two images comprise a same plurality of first feature points. A plurality of first edge line segments in one of the at least two images are detected. Four first edge line segments from the plurality of first edge line segments are determined. Locations of photographed points corresponding to the plurality of first feature points in a region formed by the four first edge line segments are determined based on location information of the plurality of first feature points. The region is determined as a rectangular region when the photographed points corresponding to the plurality of first feature points in the region are coplanar.

Abstract: A method, an apparatus, and a system for implementing private network traversal are disclosed, where a message exchanged between a TURN server in a public network and a communications terminal in a local area network is transmitted through a pre-established websocket connection. The method includes: receiving, by the TURN server, a resource allocate request sent by the communications terminal, allocating a relay address and a resource port for the communications terminal; receiving a TURN data packet sent by the communications terminal, where the TURN data packet includes communication data and a multiplexing identifier, and sending the communication data to the remote node through the communications channel identified by the multiplexing identifier, thereby solving a problem in an existing TURN technology that in case that a firewall only opening an HTTP port is deployed, communication between a communications terminal in a local area network and a remote node cannot be implemented.
Abstract translation: 公开了一种用于实现专用网络遍历的方法，装置和系统，其中在公共网络中的TURN服务器和局域网中的通信终端之间交换的消息通过预先建立的websocket连接传输。 该方法包括：由TURN服务器接收由通信终端发送的资源分配请求，为通信终端分配中继地址和资源端口; 接收由通信终端发送的TURN数据分组，其中TURN数据分组包括通信数据和复用标识符，并且通过由多路复用标识符标识的通信信道将通信数据发送到远程节点，从而解决现有的 TURN技术，如果仅部署防火墙打开HTTP端口，则无法实现局域网中的通信终端与远程节点之间的通信。
