AI Technical Summary

Benefits of technology

This patented technology allows vehicles mounted cameras to be accurately adjusted during road testing by analyzing their scenes from different angles while they are being driven along roads. By gathering this data over time, it helps improve accuracy when measuring traffic speeds and identifies areas where congestion may occur more frequently than usual.

Problems solved by technology

The technical problem addressed in this patented text relates how efficiently and accurately calibrated multi-vehicle mounted cameras (MVC) used in road monitoring systems are challenges due to limitations such as requiring manual placement during data acquisition process or lack of sufficient accuracy required at different locations along its trajectory path from one point to another.
