(1) camera retrieval flow
As shown in Figure 5, in this camera retrieval flow, the control part 11 of camera indexing unit 10 is at first according to determine the current location (steps A 1) of vehicle from the input data of position detection part 12.Then, in the current location by contrasting definite vehicle and map information 16, the cartographic information of storage, be defined as travel (steps A 2) with the road in Vehicle Driving Cycle.Then, control part 11 extracts the camera retrieval width information (steps A 3) corresponding with the road ID of the travel of determining from the road attribute database.
Then, control part 11 judges whether camera indexing unit 10 is carrying out the route guidance (steps A 4) of vehicle.Carrying out the route guidance (being yes in steps A 4) of vehicle at camera indexing unit 10, control part 11 is set in along the route in guiding the camera retrieval width that steps A 3 is extracted, and retrieves the camera (steps A 5) that exists in this camera retrieval width.Route in this guiding is equivalent to route guidance just at the travel of executory vehicle.Control part 11 is followed the trail of the route in guiding on one side, Yi Bian carry out this camera retrieval process.That is, control part 11 on one side in travel at least from the current location of vehicle to the zone of the destination of route guidance in tracking this travel (guiding route), Yi Bian carry out this camera retrieval process.Then, when all cameras (being yes in steps A 6) that the route retrieval in guiding exists in camera retrieval width, control part 11 finishes this camera retrieval flow.
On the other hand, at camera indexing unit 10 during execution path guiding (being no in steps A 4), the specialized range in the direct of travel the place ahead in the travel of control part 11 when route guidance is not carried out, be set in the camera retrieval width that steps A 3 is extracted, and retrieve the camera (steps A 7) that exists in this camera retrieval width.So-called travel when route guidance is not carried out is equivalent to the road in Vehicle Driving Cycle.Control part 11 is followed the trail of this travel on one side in the specialized range of travel, Yi Bian carry out this camera retrieval process.Then, when retrieving all cameras (being yes in steps A 8) that exist in camera retrieval width in the specialized range in vehicle direct of travel the place ahead, control part 11 finishes these camera retrieval flows.As previously discussed, this camera retrieval flow is retrieved without exception to all cameras that exist in the camera retrieval width of setting on the travel of Vehicle Driving Cycle.
(2) camera screening process
The control part 11 of camera indexing unit 10 begins this camera screening process when finishing above-mentioned camera retrieval flow.As shown in Figure 6, in this camera screening process, control part 11 judges whether to retrieve camera by the camera retrieval flow, namely judges whether to retrieve at least one camera (step B1).Do not retrieving camera (being no in step B1) by the camera retrieval flow, control part 11 finishes this camera screening process.On the other hand, when retrieving camera (being yes in step B1) by the camera retrieval flow, control part 11 is read the angle information corresponding with this camera that retrieves (step B2) from camera information storage part 17.Then, control part 11 is carried out the camera determination processing according to the angle information of the camera of reading.
This camera determination processing judges whether the camera that retrieves by above-mentioned camera retrieval flow is " notify object camera ".Particularly, control part 11 is according to the relation of the pointing direction of the pointing direction of this camera and travel, the camera that retrieves is categorized into " warning object camera ", " non-warning object camera " and reach any in " attention object camera ".
Namely, less angle in the formed angle of pointing direction of the pointing direction of camera and travel is in predetermined angular the time, it is the camera that arranges in order to monitor travel that control part 11 is regarded as this camera, and is defined as warning the object camera.In such situation, the less angle in the formed angle of pointing direction of the pointing direction of camera and travel is in 20 degree the time, is defined as warning the object camera.In addition, the warning object camera of determining like this is equivalent to the notify object camera in technical scheme.On the other hand, less angle in the formed angle of pointing direction of the pointing direction of camera and travel is not in predetermined angular the time, it is the camera that arranges in order to monitor the road different from travel that control part 11 is regarded as this camera, and is defined as non-warning object camera.For example, in order to monitor that the camera that arranges with the road of travel adjacency is non-warning object camera.In such situation, the less angle in the formed angle of pointing direction of the pointing direction of camera and travel is in 20 degree the time, is defined as non-warning object camera.
But, when the pointing direction of camera is parallel with the pointing direction of travel, can not judges clearly that this camera is the camera that monitors travel, or monitor the camera of the road different from travel.The situation that the pointing direction of so-called camera is parallel with the pointing direction of travel is that the pointing direction of camera and the formed angle of pointing direction of travel are the situation of 0 degree.So, be 0 when spending in the formed angle of pointing direction of the pointing direction of camera and travel, control part 11 is regarded as the not clear camera of monitored object to this camera, and is defined as noting the object camera.Namely, the camera that so-called monitored object is not clear may be the camera that monitors travel, may be also the camera that monitors the road except travel.The camera of the attention object of determining so in addition, is equivalent to the notify object camera in technical scheme.
At this, the content of the camera determination processing of carrying out as described above is described visually by reference Fig. 7.Namely, angle [alpha] and angle beta are all that predetermined angular is in 20 degree, wherein, angle [alpha] is the less angle in the formed angle of pointing direction r of the pointing direction a of camera C M (a) and travel R, and angle beta is the less angle in the formed angle of pointing direction r of the pointing direction b of camera C M (b) and travel R.Therefore, these camera C M (a) and camera C M (b) are confirmed as monitoring the warning object camera of the travel R in Vehicle Driving Cycle.On the other hand, in such situation, namely 20 degree are large than predetermined angular for the little angle γ in the formed angle of pointing direction r of the pointing direction c of camera C M (c) and travel R.Therefore, this camera C M (c) is confirmed as monitoring the non-warning object camera of the road different from travel R.And about camera C M (d), the formed angle of pointing direction r of its pointing direction d and travel R is 0 degree, and is namely parallel to each other.Therefore, this camera C M (d) is confirmed as the not clear attention object camera of monitored object.
As above, during any in the camera that exists being categorized into warning object camera, non-warning object camera or noting the object camera in camera retrieval width, control part 11 is carried out the camera notification modality and is set and process (step B4).Set in processing in this camera notification modality, in such situation, control part 11 is set as Show Color " redness " as the notification modality of the camera that is categorized into warning object camera.In addition, in such situation, control part 11 is set as Show Color " white " as the notification modality of the camera that is categorized into non-warning object camera.In addition, in such situation, control part 11 is set as Show Color " yellow " as the notification modality that is categorized into the camera of noting the object camera.Control part 11 finishes this camera screening process after respectively the notification modality of the camera that exists being set in camera retrieval width.As described above, this camera screening process is to screen the flow process of the camera of object by way of caution from the camera that retrieves at the camera retrieval flow.Namely, this camera screening process is to screen the flow process of the camera of object by way of caution from the camera that exists in camera retrieval width.
