Problems solved by technology
[0005] The above video image detection method is simple to operate and relatively general, but it also has obvious shortcomings.
For video features that do not exist in the feature database, the detection of feature matching cannot be realized. It is necessary to manually update the video features in the feature database and continuously maintain the feature database. This method has a large workload, requires a lot of manpower to intervene, and has low work efficiency.
