Video Generation Method Using Map Path Planning for Event Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current news reports on significant events like epidemics and tsunamis primarily use text formats, making it difficult for readers to visualize and understand the events effectively.
Innovation Solution
A video generation method that plans a path of target events on an electronic map based on their occurrence places and times, determines video sub-segments for each event, and generates a target video by combining these sub-segments with the planned path, allowing for a spatial and temporal introduction of events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text format is used for news reports on significant events, then information can be conveyed, but readers cannot effectively visualize and understand the events
Solution Approach 1:
The patent segments the event report into multiple video sub-segments, each corresponding to a specific event, and combines them with electronic map segments to create a comprehensive video presentation. This segmentation allows complex events to be broken down into manageable visual components that can be processed and understood more effectively
Solution Approach 2:
The patent transitions from traditional text-based one-dimensional information delivery to multi-dimensional video presentation by integrating electronic map spatial information with event temporal information. This dimensional change enables readers to visualize events in both space and time, significantly improving comprehension
2Loss of information
If video format is used to present events with spatial and temporal elements, then visualization is improved, but the complexity of processing and generating the video increases
Solution Approach 1:
The patent performs preliminary actions by pre-processing event data to extract key spatial and temporal information, and pre-generating video sub-segments before final assembly. This preliminary processing simplifies the subsequent video generation process and reduces overall system complexity
Solution Approach 2:
The patent introduces an intermediary processing layer that converts structured event data into video sub-segments using electronic map information as a mediator. This intermediary layer handles the complex transformations between different data formats, isolating the complexity from both data input and video output stages
3Loss of information
If multiple events are integrated into a single video, then comprehensive understanding is achieved, but the time required to process and generate the video increases
Solution Approach 1:
The patent divides multiple events into separate video sub-segments that can be processed independently and then assembled. This segmentation allows parallel processing of different events, reducing the total generation time while maintaining comprehensive coverage of all events
Solution Approach 2:
The patent employs periodic action by processing events in discrete time intervals or batches, allowing for efficient resource utilization and parallel processing. Events are processed in periodic cycles rather than sequentially, significantly reducing overall generation time

AI summary
Provided are a video generation method, an electronic device, and a non-transitory computer-readable storage medium. The implementation scheme is as follows: a place path of at least two target events is planned in an electronic map according to occurrence places of the at least two target events and occurrence time of the at least two target events, where the at least two target events have a same theme; video sub-segments of the at least two target events are respectively determined to obtain at least two video sub-segments; and a target video is generated according to the at least two video sub-segments and the place path.
