Definitions
- the invention relates to a method for setting up imaging sensors according to the preamble of Patentanspru Ches 1, a computer program product for setting change bender sensors according to the preamble of claim 9, a sensor device system according to the preamble of Pa tent compressiones 17 and a system according to the preamble of claim 25.
- imaging sensors such as e.g. Passenger counting sensors or surveillance cameras
- equipment e.g. a vehicles for passenger transport, especially in rail and road transport, or devices for room monitoring
- a device of the sensor by a Ex perten is usually necessary to ensure a functionally correct positioning and orientation of the sensor (eg, the counting sensor is functionally correct on aligning a counting line), ensuring correct configuration with parameter sets (eg recording by a video camera with the required resolution and frame rate) and ensuring proper cabling with network or bus systems.
- the object underlying the invention is to specify a method for setting up imaging sensors, a computer program product for setting up imaging sensors, a sensor device system and a system, with which the setting up, in particular for commissioning and maintenance purposes, imaging sensors, such as Passenger counting sensors and surveillance cameras, in terms of the associated effort is simplified and the associated costs is improved.
- the idea underlying the invention according to the independent claims 1, 9, 17 and 25 is, by matching an actual frame or actual video of an imaging sensor, with respect to either a sensor identification information or a port technical information and a sensor-specific reference situation in terms of positioning, alignment, configuration of a reference parameter set, such as a data transmission and electrical connection, is properly set up and aligned, and taken with the at least one reference frame or reference video in which a marker is located is to check with the selected reference frame or reference video whether the configured imaging sensor is correctly aligned, configured and wired.
- First, for a reference plant e.g. a first vehicle in the rail network (train) of a train fleet] detects the possible installation situations of imaging sensors, and defines the correct positioning, alignment, configuration with parameter sets and cabling by an expert.
- a reference plant e.g. a first vehicle in the rail network (train) of a train fleet
- the sensors in the reference system are set up and the correct setup is checked by the expert. Subsequently, the specific installation situation and the selected parameter set are stored for these sensors and a plurality of reference individual images and reference videos are recorded, possibly to different light and external conditions that can occur during operation.
- the sensors are then set up according to the specifications of the expert.
- an inventive method for setting terrorism bender sensors an inventive computer program product for setting up imaging sensors and / or he inventive sensor device system is used to check for egg nen arbitrary sensor whose device. It is initially assumed that a sensor has been correctly set up. Due to cabling or parameter set, this sensor can then be used according to the method, the computer Program product and / or the sensor device system are addressed accordingly.
- a correct actual sensor ID and / or a correct actual sensor type are reported by the sensor. This is done first by comparison with a stored setpoint Id of the sensor and / or a stored target type. If the sensor does not know its actual ID or its actual type, the adjustment is made via a correct connection-related actual port number with a target port number.
- a check is then made as to whether a configured actual parameter set reported by the sensor coincides with a setpoint parameter set required on the basis of the installation situation and, if appropriate, the sensor type. If not, a first error message is sent to a downstream in-put setting / maintenance system and / or to the sensor. Parallel to this, optionally a corrected, correct parameter set can be transmitted to the sensor either directly or indirectly via the commissioning / maintenance system by appropriate insertion into the sensor.
- a third step then the sensor-supplied IST individual images or actual videos with the reference frames and reference videos are compared with respect to the lo calized markers (striking objects or artificial markers). If these are not located at the intended locations, then either the sensor has slipped, incorrectly wired or incorrectly installed. In this case, a second error message is sent to the commissioning / maintenance system and / or the sensor. Since faulty devices are not the standard case, these errors can then be corrected manually. Occasional false error messages can also be corrected manually.
- the method, the computer program product and / or the sensor device system can be used. be used for monitoring the setup of the sensor during operation. This is useful, for example, if due to the environment or maintenance a Modifika tion in the sensor device (eg by slipping of the sensor, by software updates) is to be expected. In this case, you would just record the reference frames or reference videos only for the sensor that has been set up and not use them for other sensors.
- the misalignment of imaging sensors could be compensated for by intelligent software of the sensor, i. the ak quirATOR image material are converted.
- the misalignment can be compensated by considering the misalignment shifted image section (assuming moderate misalignments).
- the concept could be extended in principle for sensors of all kinds.
- environmental factors would have to be influenced if necessary.
- an automated announcement could be made in one go and then checked for correct entry. This could be used to check both announcement systems and microphones (eg in a microphone unit).
- - Errors can be automatically detected by changing the device during operation.
- a plant e.g. a vehicle for passenger transport, especially in rail and road traffic, or a device for room surveillance.
- FIGURE shows a sensor device system SES for setting up imaging sensors in a system AL, such as a vehicle FZ for passenger transport, especially in rail and road transport, or a device for room monitoring VRÜ.

- At least one reference single image R-EB or reference video R-VD is recorded with the imaging sensor S BG thus arranged.
- Each reference frame R-EB or reference video R-VD recorded in this way is combined with the reference parameter set R-PS, the desired sensor identification information S-SKI, S-SK, S-STD and the connection-related desired port information S-S.
- PI is supplied from the imaging sensor S BG to the database DBK and stored therein.
- the imaging sensor S BG is soft and hard-formed in such a way that in the recorded reference frame R-EB or reference video R-VD at least one marking a distinctive object or one for the sensor-specific reference situation for recording of the reference frame R-EB or reference videos R-VD gefaf fene artificial marker is located and provided with the marker reference frame R-EB M or reference video R-VD M in turn supplied to the database DBK and is stored in this.
- the imaging sensor S B G forms this together with the database DBK a commonrelisein unit with the control unit STE.
- control unit STE contains a computer program product CPP for setting up imaging sensors with a non-volatile, readable memory SP, in which processor-readable control program instructions of a program module PGM carrying out the installation are stored, and a processor PZ connected to the memory SP, which executes the control program instructions of the program module PGM for setting up the imaging sensors.
- a first step for carrying out this check of the set-up imaging sensor S BG , the reference frame R-EB M or reference video R-VD M provided with the marking, the reference parameter set R- PS, the target sensor identification information S-SKI, S-SK, S-STD and the connector-related desired port information S-PI loaded into the processor PZ.

- the generated by the control unit STE error messages FM1, FM2 and possibly additionally generated, corrected correct, corrected parameter set PS K are transmitted to commissioning and maintenance systems IWS to a commissioning / maintenance system IWS, which is for this purpose connected to the control unit STE.
- the corrected, correct parameter set PS K can be recorded either directly by the control unit STE or indirectly via the commissioning / maintenance system IWS in the set up, imaging sensor S BG for parameter set correction.

- the second error message FM2 is used to signal and display a faulty device / misalignment of the imaging sensor S BG .
- the incorrect means / misalignment of the imaging sensor S BG occurs, for example, by slippage of the sensor, a faulty data transmission technology and electrical connection rule of the sensor, eg by incorrect wiring or obstruction, a poor alignment of the sensor or not yet done software update.
- the faulty device / misalignment due to poor direction of the sensor can be compensated either by a loadable in the imaging sensor S BG or pre installed smart software, which can be, for example, as "App" out compensate, by the chanbie the sensor S BG supplied image material is converted, or - in the case of passenger counting sensors or surveillance cameras as imaging sensor S BG , which often cover a larger Be rich than he is necessary for counting or monitoring - compensate by viewing a misalignment / Fehlaus direction shifted image detail ,
