- the Informationsda ⁇ tenbank IDB of the image analysis apparatus BAV is assigned in such a way and with this connected, as the calculation / evaluation BAWE ausensegeSysteme for the calculation / and lane-based image analysis for Streckenstrom- / Streckenverlauf- / Obj ect recognition accesses the image meta information BMI stored in the information database IDB.
- the information database IDB is preferably outside the Marsh analysesvorrich ⁇ tion BAV, eg as a database, arranged in the railcar or is designed as a data cloud.
- the calculation / evaluation device BAWE preferably has a non-volatile, readable memory SP in which processor-readable control program instructions of a picture analysis for route / route / Obj ect recognition-controlling program module PGM are stored, and a processor PZ, which executes the control program commands of the program module PGM for the calculation / evaluation-based and lane-based image analysis for track / route / Obj ekt recognition performs.
- the processor accesses in addition - in addition to the accesses to the image-BMI meta information in the information database IDB - for control purposes and for reading out data to the image recording device and the image BAZG spoke pure Rich ⁇ tung BSPE to.
- the lane-based image analysis in the calculation / evaluation BAWE advantageously such that in the image BI FSB , BI GLB is recognized where the Signaling system SI, AL or the track system SAL can be found by
- BI FSB BI GLB is identified, in which a distinctive Anlagenmerk ⁇ times the track system SAL or the signal SI of the system AL can be seen, 2) the first image section BAS1 is determined in the image subregion BTB, through which the traffic lane FS, GL used by the railway vehicle BFZ, SFZ performs,
- Meta information BMI and a standard edge detection algorithm is attempted to detect the outer edges of the track system SAL or the signal system SI, AL in the distance 3) determined by the lane FS, GL until the known and recognized outer edge substantially überde ⁇ bridges ,
- the calculation / evaluation device BAWE in the lane-based image analysis continues to be such in an advantageous manner designed that in the image BI FSB / BI GLB is detected, in which direction, in particular LEFT, RIGHT or STRAIGHT ⁇ OFF, the railway vehicle BFZ, SFZ drives by for the detected from the detected course lane FS, GL
- a pseudo-GERADEAUS lane in particular a pseudo-GERADEAUS track, is artificially generated by linear updating of the lane FS, GL used by the railway vehicle BFZ, SFZ in accordance with the image area BIB,
- a LEFT direction eg a LEFT curve, is recognized when the used lane FS, GL is to the left of the pseudo-GERADEAUS lane,
- a RIGHT direction e.g. a right-hand turn, is recognized when the used lane FS, GL is to the right of the pseudo-straight lane.
- calculation / evaluation device BAWE in the case of lane-based image analysis is furthermore advantageously designed in such a way that in the image
- BI FSB BI GLB is detected, whether at least one object OBJ, which may be, for example, a person, an animal, a movable or stationary object on the used lane FS, GL by
- the calculation / evaluation device BAWE designed accordingly that in the image BI ⁇ SB ⁇ BI GLB is detected, how far the railway vehicle BFZ, SFZ is spaced from the object OBJ on the used lane FS, GL has been recognized by the one of a pixel width of the lane FS, G) in the image area BIB and a pixel width of the lane FS, GL in the third
- Image section BAS3, in which the object OBJ is located are set in relation to each other, from this ratio and the obtained from the known third metadata width of the lane FS, GL of said distance is calculated.
- image analyzing device BAV an automated (autonomous) or assisted driving of the railway vehicle or the railway vehicle BFZ SFZ without additional infrastructure along a route as may ⁇ be suspended or even realized. This is especially true if the image analysis device BAV is realized as a virtual machine which is designed and functions in the sense of a " software- defined signal recognition of rail traffic system".
