A Method for Remote Guidance Using Video Annotation

Abstract

The invention discloses a method for performing long-distance guidance by use of video annotation. The method comprises the following steps: S1, communicating with a dispatching desk by virtue of a mobile terminal and transmitting relevant failure information and onsite videos to the dispatching desk by virtue of voice description; S2, starting annotation on a video interface by the dispatching desk, automatically locking a real-time video by the mobile terminal and transmitting the real-time video to the dispatching desk; S3, covering a locked video image with a transparent window respectively by virtue of the dispatching desk and the mobile terminal, performing annotation operation on the transparent window and transmitting an annotation instruction to the mobile terminal by virtue of the dispatching desk, and displaying synchronously by virtue of the mobile terminal; S4, processing the failure information according to the annotation operation content and voice communication by virtue of the mobile terminal and unlocking the real-time video image by virtue of the mobile terminal; S5, repeating the steps S1 to S4 until all the failures are eliminated. By use of the method disclosed by the invention, the maintenance and inspection personnel of the mobile terminal seem to accept the personal guidance of dispatching desk technical support personnel, so that the usage experience is effectively improved.

Description

technical field [0001] The invention relates to a remote guidance method, in particular to a method for remote guidance using video annotation in an IP multimedia dispatch communication system, and belongs to the technical field of dispatch communication. Background technique [0002] In the application scenarios of maintenance inspection systems such as remote repair systems and remote maintenance systems, relevant technical experts are on duty in the maintenance center; maintenance inspection personnel hold terminals with real-time video communication capabilities to perform inspection and maintenance operations. When the maintenance patrol personnel perform specific equipment maintenance operations, if they need the support of technical experts in the maintenance center, they will initiate technical assistance to the relevant technical experts in the maintenance center. Relevant technical experts in the maintenance center accept the request, open the mobile real-time vide...

Problems solved by technology

However, in the remote guidance process, it is necessary to rely on the projection unit to project the marked image in the imaging area of ​​the imaging unit, and then the marking adjustment unit adjusts the conditions for projecting the marked image according to the conditions in the imaging area of ​​the imaging unit. It is time-consuming and labor-intensive to perform corresponding operations on the labels, which is not conducive to timely troubleshooting of faults
