Implementing method of electronic cloud deck, front end device and receiving device

Abstract

The invention provides an implementing method of an electronic cloud deck, a front end device and a receiving device, and relates to the field of video monitoring, so that when moving a monitoring area, a user can move the area in smaller units, so as to obtain a smooth effect and promote the user experience. The method comprises the following steps of: receiving a user command by a sending terminal and cutting the image according to image position information in the command to obtain a cut image; expanding the cut image to obtain a standard image area comprising the area to be cut; and coding the expanded image and sending the coded code stream and expanding parameters to user equipment for the user equipment to decode the code stream and combine the expanding parameters to obtain the original cut image. The invention is used for implementing the electronic cloud deck.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method for realizing an electronic pan-tilt, a front-end device and a receiving device. Background technique [0002] At present, in the implementation scheme of network monitoring, there are mainly two implementation methods, one is to set up a network camera IPC (Internet Protocol Camera, IPC) on a fixed physical pan-tilt, and the physical pan-tilt receives the instructions of the remote user equipment, through Its own rotation achieves the effect of changing the monitoring area; the other is through the electronic pan / tilt method, that is, cutting the images collected by the IPC, and after receiving the instructions from the remote user equipment, according to the user instructions, the image of the user's required monitoring area will be cut. Send it to the remote user equipment, and simulate the moving process of the physical pan / tilt by sending images of different position...

Problems solved by technology

[0003] However, although the current physical pan-tilt solution can support multi-directional movement, so that the monitoring field of view of the IPC can be adjusted according to the user's instructions, the cost of using the physical pan-tilt solution is relatively high

In the implementation scheme of the electronic pan/tilt, when the process of image cropping is carried out on the user equipment, the IPC sends the whole monitoring image, but the...
