3 Terms and definitions
The following terms and definitions defined in GB/T 33745-2017 and GB/T 33474-2016 apply to this document.
3.1 Perceptual object
Object
A physical entity that collects information through a sensing device.
3.2 Information fusion
Multi-level multi-faceted processing of multi-source information (in the Internet of Things system), time-space unification, error compensation, correlation, estimation, etc.
Get accurate object state estimates, complete, timely object properties, posture, and impact estimates.
3.3 Time and space unified timeandspaceunification
The information in the input local time and space coordinates is transformed into a unified system reference time and space coordinates.
3.4 Error compensation
A process of estimating and compensating for time, space, and other characteristic errors of input object information to achieve time synchronization and cancellation
In addition to or reduce space and other feature errors.
3.5 Information association
From the multi-source multi-object information (signal, data) set, a process of representing the same object information set is generated.
3.6 Signal detection
Time-space unification, error compensation, signal correlation, signal accumulation and feature extraction for multi-source measurement signals to detect the target as early as possible
The processing of the standard signal.
