Abstract

The invention provides a vector control method and device for a remote labeling signal and a signal processing system, and belongs to the technical field of signal labeling. According to the vector control method and device for the remote labeling signal and the signal processing system, which are provided by the embodiments of the invention, displacement information of a second reference point inae vector control region of a labeling signal to be moved is acquired according to a remote control end, and a target position of the labeling signal on a local display screen is determined in orderto display the moved labeling signal on the local display screen. Repeated manual drawing of the labeling signal is not needed, the consistency of attribute parameters such as the size and the shape of the labeling signal before and after moving can be kept, and when one labeling signal is moved under an application scene with a plurality of overlapped labeling signals, the integrity of other labeling signals cannot be destroyed.

Description

technical field [0001] The present invention relates to the technical field of signal labeling, in particular to a vector control method, device and signal processing system for remote labeling signals. Background technique [0002] In current labeling application scenarios, especially when labeling based on video signals, such as labeling video content displayed on an electronic whiteboard, the video content corresponding to the labeling signal changes in real time. For example: to mark a movable target in the video content, after adding the mark signal, if the position of the target changes, the position of the mark signal needs to be modified in real time. [0003] When marking a movable target in the existing scheme, the original marking signal can only be erased, and then re-adding the marking signal at the new target position. Such as figure 1 with figure 2 as shown, figure 1 The initial labeling signals shown in include horizontal and vertical lines. Suppose the...
