Mobile unit identification apparatus and method and apparatus for automatically warning to mobile unit
First Claim
1. A mobile unit identification apparatus, comprising:
- an image storage device storing time series pictures taken with an electronic camera to be trained on a region including an on-road real gate; and
an image processor, receiving a real identification code having been assigned to a mobile unit side communication apparatus passing through said real gate, bringing a mobile unit passing through a slit in ones of said pictures into correspondence with said real identification code by processing said time series pictures stored, said slit corresponding to said real gate, tracking said mobile unit having been brought into said correspondence by processing said time series pictures, outputting information on said tracking.

Abstract
By narrow region communication between a gate side communication apparatus (G-COM) and a mobile unit side communication apparatus (M-COM) passing through an on-road real gate at an interconnection, the G-COM assigns a real identification code (R-ID) ID1 including an intersection number to the M-COM after receiving a R-ID ID0 having been assigned from the M-COM, while time series pictures of the intersection including all real gates are taken by a camera 15 installed to assign a virtual identification code (V-ID) to a mobile unit passing through a slit, corresponding to a real gate, in pictures by processing them. In response to the assignment of the R-ID, the R-ID is brought into correspondence with the V-ID. The mobile unit is tracked and when an anomalous behavior thereof is detected in pictures, warning information is transmitted to the M-COM using the corresponding R-ID. By gathering sets of ID0 and ID1 associated with each other in a plurality of intersections, a mobile unit having displayed an anomalous behavior is tracked.

10. A warning method to mobile units, comprising the steps of:
-
(a) performing narrow region communication with a mobile unit side communication apparatus passing through an on-road real gate either to assign a real identification code to said mobile unit side communication apparatus or to receive the real identification code having been assigned to the mobile unit side communication apparatus;
(b) taking time series pictures with an electronic camera installed on a road side with training on a region including said real gate;
(c) processing said time series pictures to bring a mobile unit passing through a slit in ones of said pictures into correspondence with said real identification code, said slit corresponding to said real gate;
(d) processing said time series pictures to track said mobile unit having been brought into said correspondence to detect an anomalous behavior thereof; and
(e) transmitting warning information to the mobile unit side communication apparatus with said real identification code of said mobile unit having displayed said anomalous behavior or of another mobile unit associated therewith. - View Dependent Claims (11, 12, 13, 15, 16)

14. A warning method to mobile units, comprising the steps of:
-
(a) performing narrow region communication with a mobile unit side communication apparatus passing through an on-road real gate to assign a real identification code to said mobile unit side communication apparatus after receiving another real identification code having been assigned to the mobile unit side communication apparatus;
(b) taking time series pictures with an electronic camera installed on a road side with training on a region including said real gate;
(c) processing said time series pictures to bring a mobile unit passing through a slit in ones of said pictures into correspondence with said real identification code, said slit corresponding to said real gate; and
(d) processing said time series pictures to track said mobile unit having been brought into said correspondence to detect an anomalous behavior thereof;
wherein the steps (a) through (d) are executed at each of a plurality of road sides, said method further comprising the step of;
(e) gathering sets each having said assigned and received real identification codes, said sets being associated with each other among said plurality of road sides, to track a mobile unit having displayed an anomalous behavior.
