SYSTEM AND METHOD FOR ACCURATELY ANALYZING SENSED DATA

摘要

A system for analyzing sensed data. A triggering mechanism is responsive to the presence of a target. A sensor acquires sensed data of the target, for example, an image. A processor analyzes the sensed data to detect the target. The signals generated by the triggering mechanism and the sensor are reconciled. In the reconciliation of the signals, when a pair of signals each indicate the presence of the target within a predefined time period, a target data set corresponding to the pair of signals is generated. When the presence of the target is indicated by only one of the triggering mechanism and sensor, the detection of target or the failure to detect the target is more reliable is reconciled. If the signal indicating detection of the target is determined to be more reliable, a target data set is generated. A method for analyzing sensed data is also disclosed.

1. A system for analyzing sensed data to acquire information about at least one target in at least one predefined spatial zone, the system comprising:
a triggering mechanism configured to communicate to the system a first signal responsive to the presence of a target in a first predefined spatial zone; a sensor configured to acquire sensed data of the target in a second predefined spatial zone and communicate to the system a second signal including the sensed data; at least one processor in communication with the system configured to analyze the sensed data and determine if the sensed data detects the target; and wherein the at least one processor is further configured to reconcile the first and second signals respectively generated by the triggering mechanism and the sensor wherein:
when a pair of first and second signals each respectively indicate the presence of the target in the first and second predefined spatial zones within a predefined time period, the at least one processor generates a target data set corresponding to the pair of first and second signals; andwhen the detection of the target in one of the first and second predefined spatial zones is indicated by only one of the first and second signals, the at least one processor is configured to determine whether the detection of the target is more reliable than the absence of detection, and, if the detection of the target is determined to be more reliable, the at least one processor generates a target data set corresponding to the one signal indicating detection of the target.
