Definitions
- the present invention particularly relates to a system for
- a system for determining the position of movable dummy elements in a covered test area in particular in a hall.
- the system has a camera which is set up to take an image of a monitored area of the roofed over
- AD IG: MJ: tp Marker element, which is movable with the dummy element in such a way that it is visible on the recorded image of the monitoring area, and a position determination unit which is coupled to the camera and is configured such that based on the recorded image the position of the Marker element can be determined in the monitoring area.
- a method for operating the above-described system for determining the position of movable dummy elements in a covered test site, in particular in a hall is described. According to the method, the position of the marker element in the monitoring area is determined based on the recorded image.
- the marker element is arranged on the dummy element.
- the marker element is arranged on the dummy element in such a way that it is visible on the recorded image of the monitored area.
- the system also has a further (stationary and immovable) marker element which is arranged in a stationary manner in the monitoring area in such a way that it is visible on the recorded image of the monitoring area.
- the position of the stationary marker element is predefined and known, so that, for example, the recorded image of the monitored area can be calibrated using the stationary marker element
- Configured position determination unit to place a virtual grid over the image, each grid field of the grid being indicative of a specific position in the monitoring area.
- a grid field is smaller than 9 cm 2 , in particular smaller than 4 cm 2 , further in particular smaller than 2 cm 2 . If the dummy element is thus located in a grid point, the position of the dummy element can, conversely, be determined based on the knowledge of the grid point.
- the camera is set up to record a further image after a specific time offset after the image, the position determination unit being configured to use the recorded image and the further image as a basis
- the system has a further camera, which is set up to take an image of another
- the position determination unit being coupled to the further camera and configured such that, based on the recorded image of the further camera, the position of the marker element in the further
- Monitoring area can be determined.
- Monitoring area positioned next to the monitoring area, wherein at least one edge area of the monitoring area and another edge area of the further monitoring area overlap.
- the system has a further movable dummy element which can be moved through the monitoring area and / or the further monitoring area, the further dummy element having a further marker element which is arranged in such a way that it can be seen on the recorded image of
- the image of the further monitoring area is visible. According to an exemplary embodiment, the
- Position determining unit configured to determine a collision point of the dummy element with the further dummy element.
- the dummy element is a two-wheeler, a motorcycle or a bicycle, a motor vehicle, in particular a car or a truck, a human dummy or an animal dummy.
- the system has a movable platform, the dummy element being arranged on the movable platform.
- the marker element is arranged on the movable platform.
- the system has at least one lighting means for illuminating the monitoring area with electromagnetic radiation, the camera being set up to record the electromagnetic radiation, by means of which the lighting means illuminating the monitoring area, in the image.
- the electromagnetic radiation is generated in the visible spectrum with a wavelength of 380 to 750 nm, or the electromagnetic radiation is generated in the invisible spectrum, in particular as infrared radiation, ultraviolet radiation or terahertz radiation.
- the marker element is fluorescent.
- the marker element is a light source, which in particular has an LED, which is visible Generates light or invisible light that can be recorded by the camera.
- the marker element is set up to generate or reflect visible and / or invisible light.
- the camera is
- the covered test area can be darkened so that night tests can be carried out.
- the camera has a resolution of less than 10 megapixels, the camera being designed in particular to record an image in the 4: 3 format.
- the camera has 10 megapixels with a
- the position determination unit can thus quickly process the exact position data and the direction and movement information, so that an exact movement profile of the dummy element can be calculated without delay.
- the low-resolution images generate a smaller amount of data, a large number of such unresolved images can be recorded quickly and processed quickly. This is a change of direction or
- the change in speed of the dummy element can be quickly identified and measured.
- the marker element has a round or rectangular circumference, the marker element having particularly two color areas, in particular white and black.
- the marker element has a direction indicator which indicates an orientation of the object.
- the defined alignment of the object shows the direction, for example
- Front of the dummy element front or face of a
- the orientation of the object can, for example, be the predetermined one
- a direction vector of the dummy element can be determined based on the recording of a single image.
- the direction pointer represents an arrow in such a way that it has an arrangement of at least two, in particular three, points or has a specific arrangement of at least 2-colored patterns to define the direction of movement.
- two points of a marker element can indicate a direction of information or an orientation of the marker element and corresponding dummy element due to their spacing direction.
- the marker element has an information field which is arranged in such a way that it is visible on the recorded image of the monitored area, the information field being designed that, based on the image of the
- Information field in particular has a barcode or an identification number.
- the information field can, for example, have information about the type of dummy element, for example whether the dummy element is a vehicle or a pedestrian. Furthermore, the information field can have information about geometric shapes or speeds of the dummy element.
- the position determination unit recognizes the position of the dummy element in the monitoring area based on the analysis of the recorded image and the marker element recognizable thereon.
- a virtual grid from the position determination unit can be placed over the image of the monitoring area, so that the position of the dummy element can be inferred from the presence of the marker element in a first grid area.
- Monitoring area are arranged, which are also in the
- the system 100 has a camera 101, which is set up to record an image of a surveillance area 103 of the covered test site 130, a movable dummy element 110 which can be moved through the surveillance area 103, the dummy element 110 having a marker element 120 which is arranged in such a way that it is visible on the recorded image of the surveillance area 103, and a position determination unit 106, which is coupled to the camera 101 and is configured such that, based on the recorded image, the position of the marker element 120 in the surveillance area 102
