Definitions

  • the present invention relates to a method according to the preamble of claim 1.
  • TASK Various devices for monitoring a door / gate area are known and commonly used in the prior art.
  • TASK The object of the invention is to provide a monitoring system which is inexpensive and allows a high degree of flexibility with regard to use. It should be made available on the basis of the inventive method, a cost-effective basic principle that can be used in a variety of ways.
  • the goal area should be the areas or rooms immediately around a gate. Immediately here an area with about 30 to 50 cm or 30 to 100 cm distance from the middle of the passage up to 15 m distance is considered. Image data is not used for the detection of the door movement path or the door movement path (door height). The Tor Gaysbahn is not visible in the image area.
  • a gate edge of a door area is monitored by a commercially available additional sensor.
  • Gate edge in this context means the area of the gates, which hit each other flush with the floor when properly closed.
  • the further sensor should in this case be connected directly or indirectly via the computer with a drive of the door to interrupt a stopping a closing movement in an emergency.
  • infrared sensors, ultrasonic sensors, radar sensors or the like come into consideration.
  • a gate are regularly opening an opening devices in which not only people but also objects, such as a vehicle can drive through, the door from the top to a floor towards the passage partially or completely closed and in the fully open state, the largest defined distance to the floor.
  • the distance specified for the monitoring area refers to a radius from the center of the passage opening.
  • Even smaller or larger areas around the gate can be monitored. This must be set individually by the user. It depends, for example, on whether only passenger traffic or, for example, vehicle traffic is expected. In vehicle traffic, it is advisable that a greater distance is monitored around the gate, as vehicles can be faster than people. Regularly, an area of 15 m from the center of the passage is considered here.
  • the method according to the invention requires a first acquisition medium and a second acquisition medium.
  • the recording medium should be all devices that record a process. For example, it should not be mentioned conclusively that so-called CCD cameras, optical lenses in general, sensors, thermal imaging cameras or similar devices should be meant.
  • the computer unit ascertains the height to a floor in the case of existing persons or objects entering and / or entering the surveillance area.
  • the arithmetic unit uses the information, data and / or the recordings of the two acquisition media.
  • the computer unit prioritizes the highest object or person and opens the door and thus the passage only to the point where the highest person or object can pass.
  • stored data of the Tor Gaysbahn be coupled with the opening and closing pulses of the drive of the gate and transmitted to the gate control, so that the gate or height-variable is opened, the gate height is determined by a stored in the computer unit Torschulsprofil or another sensor.
  • each acquisition medium has exactly two cameras. Consequently, a total of four cameras are used in the inventive method, which are divided equally into two acquisition media. However, it is not mandatory that these collection media are arranged separately from each other.
  • the first acquisition medium and the second acquisition medium may be disposed on the same panel. Particularly advantageous have distinguished as single cameras here CCD cameras. These are inexpensive to purchase and, because of their advanced degree of miniaturization, have considerable advantages for the structurally appealing realization of a project using the method according to the invention.
  • This computer unit is connected to the first acquisition medium and the second acquisition medium.
  • the computer unit receives information and data from the first acquisition medium and the second acquisition medium.
  • these are recordings.
  • a first recording is provided by the first acquisition medium.
  • a second recording is made available by the second acquisition medium.
  • the first shot and the second shot are usually two-dimensional representations of the gate area to be monitored. So it is either four two-dimensional shots of four cameras, which in the computer unit are combined to obtain two three-dimensional images.
  • each acquisition medium each has a slave computer.
  • the respective auxiliary computer would then already generate a three-dimensional recording from the two two-dimensional recordings of the two cameras, which are then forwarded to the computer unit.
  • the computer unit couples the first recording of the first detection medium with the second recording of the second detection medium.
  • the first image is the two-dimensional or three-dimensional image of the first acquisition medium and the second image is the two-dimensional or three-dimensional image of the second acquisition medium.
  • Coupling here means that the computer unit sets the two recordings in relation to each other in such a way that the persons and objects shown on both recordings receive a three-dimensional form.
  • the computer unit also takes into account the location of the first acquisition medium and the location of the second acquisition medium.
  • the computer unit By combining the location of the acquisition media and the first recording and the second recording, the computer unit generates a three-dimensional image, which serves as a basis for further method steps.
  • the three-dimensional image is stored in a memory of the computer unit.
  • a three-dimensional film of a multiplicity of three-dimensional images can be generated.
  • the computer unit can also be set by the user in such a way that, for example, only every tenth three-dimensional image or every hundredth three-dimensional image or in a different manner is filed in a filtered manner. It is also conceivable that a continuous loop is recorded. This in turn means that, for example, a certain period of time is recorded and stored and then the stored recording is overwritten by a new recording.
  • the way in which the computer unit accesses the memory depends only on the will and the requirements of the specific circumstances. In security-relevant areas, it certainly also makes sense that no overwriting of the recording is made.
  • the computer unit Based on the generated three-dimensional images depending on the locations of the first detection medium and the second detection medium and the first recording of the first detection medium and the second recording of the second detection medium, the computer unit is possible to calculate a distance of an object or a person to the Tordium.
  • the computer unit Due to the generated three-dimensional images depending on the locations of the first acquisition medium and the second acquisition medium and the first recording of the first acquisition medium and the second recording of the second acquisition medium, the computer unit is still possible, the position of an object or a person in the surveillance area and / or in to calculate the gate area. For this, the computer unit must be supplied with the location of the door area or the door. The computer unit then calculates the position of the object or person to the gate.
  • a signal is output by the computer unit.
  • the signal may be, for example, an opening or closing of the gate.
  • This signal is output can through the user can be chosen freely. In addition, it must be related to how long the opening time of the gate is.
  • a predefined change is to be understood such that the computer unit holds a large number of changes and outputs a signal when one of these predefined changes occurs. If none of these predefined changes occur, no signal would be output accordingly.
  • a first software can be included in the computer unit, which compares the three-dimensional images in sequence with one another and determines changes or confirmations in the sequence with stored information.
  • the first software is suitable for the fact that information stored on the basis of the sequence of recorded three-dimensional images exists in such a way that the computer unit can calculate whether the person or the object merely passes by the gate or wants to pass through the gate.
  • Corresponding movement patterns may be present as deposited information in the first software. If there is a defined change, then the computer unit could output a specific signal to the gate or rather its drive. Then the door could open, close or stop accordingly. However, the signal can also be such that the door does not automatically open, close or stop or be unlocked.
  • a size or a height of the object or of the person can be determined in order to make the opening of the door in an adapted manner to the person or the object. For example, become two objects or people at the same time recorded, the central computer unit compares the height values and prioritizes the signal according to the object height or height. For example, a gate is opened only as far as the highest object needed to pass through the opening. The switching time for the opening is thus determined as a function of the object height, the object speed and the door speed by the software and algorithms. The goal can take any position between the end positions. In this way, energy and time could be saved, for example, would be avoided that heated or cooled indoor air escapes unnecessarily to the outside.
  • a second software is to be present in the computer unit which categorizes persons and objects on the three-dimensional images by comparison with stored information. For example, this second software should recognize the difference between a person and an object. But it should also recognize whether an object is large or small or a vehicle or a flowerpot.
  • the computer unit, operated by the second software accesses stored information.
  • An apparatus for carrying out the method according to the invention consists primarily of the computer unit of the first acquisition medium and the second acquisition medium, wherein the computer unit, the first acquisition medium and the second acquisition medium are connected to each other and the computer unit can output a signal to open the gate or close. However, this signal can also be such that, for example, a third person is informed.
  • first detection medium and / or the second detection medium can be arranged automatically pivotable. Due to the pivoting movements, the respective detection medium would be able to detect a larger area. The pivoting movement would take place automatically and run in a defined pitch circle. In addition, there should be a radio connection with 2.4 Ghz between the individual components for the transmission of signals and data. This not only enables fast and simple data transmission, but also, for example, the simplified installation of a software update and easier replacement of individual components.
