Definitions
- the invention relates to a lighting device for a surveillance camera with a plurality, each having a light emitting axis having bulbs.
- the illuminant axes intersect an optical axis the security camera, d. H. the illuminant axes of the bulbs run not parallel to the optical axis of the surveillance camera.
- This will be a uniform illumination of the receiving area or the receiving space reached in front of the surveillance camera by means of the illumination device.
- the contrast of the illumination device according to the invention The image obtained is uniform over the entire image area high and also well suited for evaluation by means of automated Image processing algorithms. Possibly security-related items and details in the border area of the image are easy to recognize.
- Fig. 1 shows the lighting device 1 in a view from above.
- the illumination device 1 surrounds a surveillance camera 2 with a lens 3.
- the objective 3 is provided with a diaphragm 4 in order to largely prevent dazzling of the surveillance camera 2 by the illumination device 1.
- the surveillance camera 2 has an optical axis O which is perpendicular to the plane of the drawing or to a plane of the illuminant plane E spanned by an x and y axis.
- the arrow on the optical axis O points in the direction of a in the drawing for better clarity not shown in detail, in front of the surveillance camera 2 in the monitoring room or in the surveillance area located receiving object.
- the objective 3 and the diaphragm 4 are rotationally symmetrical with respect to the optical axis O positioned. Notwithstanding this arrangement shown, other positions, such as an eccentric arrangement of the surveillance camera 2, the aperture 4 and the illumination device 1 are possible.
- the illumination device 1 comprises eight light sources Lm 1,..., N , which are arranged along a circular line 6 and which lie in the illuminant plane E spanned by the x and y axes.
- the lighting means Lm 1, ..., n respectively equal distances to the adjacent light source Lm 1, ..., n on.
- the light sources Lm 1,..., N each have a light-emitting axis Lma 1,..., N and emit radiation in the near infrared range or radiation in the visible range substantially in the direction of the arrow on the respective light source axis Lma 1 ,. .n down.
- the orientation of the illuminant axes Lma 1,..., N thus corresponds to the main emission direction of the respective luminous means Lm 1,..., N.
- the arrangement of the lamps Lm 1, ..., n can also be done in other ways than in the positioning shown in Fig. 1. For example, it is conceivable to position the light sources Lm 1,..., N along a square, rectangular or elliptical line around the surveillance camera 2. Alternatively, a statistically distributed over the surface arrangement of the lamps Lm 1, ..., n is conceivable. Furthermore, it is not necessary for the light sources Lm 1,..., N to be arranged in a luminous means plane E. For example, it is conceivable that the light sources Lm 1,..., N have different height positions with respect to the optical axis O and are arranged in different planes running parallel to the light-emitting surface E. Furthermore, the number of light sources Lm 1,..., N is not limited to the number of eight light sources Lm 1,..., N shown in the exemplary embodiment.
- light-emitting diodes Lm 1,..., N are used, preferably infrared light-emitting diodes (IR-ED) or light-emitting diodes (LEDs) which emit light, above all in the visible range.
- IR-ED infrared light-emitting diodes
- LEDs light-emitting diodes
- the light emitting diodes or the infrared light emitting diodes have the advantage of a long life and a low vibration sensitivity. As a result, diodes are virtually maintenance free.
- other light sources Lm 1,..., N can also be used, such as infrared lasers, infrared laser diodes or incandescent lamps.
- the illuminant axis Lma 1 of the first luminous means Lm 1 with an x-axis includes, for example, an angle ⁇ 1 of approximately 45 °.
- the y-axis is arranged at right angles to the x-axis.
- the angles .psi..sub.2 ,..., N between the other illuminant axes Lma 2,..., N of the luminous means Lm 2,..., N and the x-axis preferably increase depending on their position on the circular line 6 in each case in 45 ° steps, ie have values of about 90 °, 135 °, 180 °, 225 °, 270 °, 315 ° and 360 °.
- the angles ⁇ 1, ..., n can take any value between 0 ° and 360 °.
- the respective illuminant axis Lma 1,..., N should preferably be oriented such that it does not point exclusively to the camera 2 or to the aperture 4. This ensures that the main emission direction of each luminous means Lm 1,..., N is directed away from the surveillance camera 2 and the optical axis O substantially to the outside.
- a uniform increase of the angle ⁇ as shown in the embodiment of FIGS. 1, 2 as a function of the position of the luminous means Lm 1, .., n on the circular line 6 is not necessary.
- the number of lamps Lm 1,..., N used and their orientation depends above all on their radiation intensity, the size and the geometry of the surveillance area monitored by the surveillance camera or the surveillance space. Depending on these parameters, other values for the angle ⁇ depending on the arrangement of the lamps Lm 1, ..., n on the circle 6 may be required in order to achieve optimum reproduction of a photographic object.
- a number of seven light sources Lm 1,..., N arranged in a rotationally symmetrical manner about the optical axis O have proven to be particularly advantageous for the control of smaller surveillance spaces or monitoring areas.
- the experimental arrangement is not shown in the figures for the sake of clarity.
- the seven lamps Lm 1, .., 7 are in this case, starting from a "12 o'clock position" on a circular line along, evenly spaced from each other.
- "12 o'clock position" means that the luminous means Lm 1 is arranged in the upper intersection between the y-axis and the circular line or whose illuminant axis Lma m1 points in this direction in the direction of the y-axis.
- the further illuminant axes Lma 2,..., 7 of the luminous means Lm 2,..., 7 rotate clockwise with the x-axis, for example angles ⁇ 1 in each case . ..., 7 from 90 ° ⁇ 10 °, 230 ° ⁇ 10 °, 255 ° ⁇ 10 °, 270 ° ⁇ 10 °, 270 ° ⁇ 10 °, 285 ° ⁇ 10 °, 320 ° ⁇ 10 °.
- FIG. 2 shows the illumination device 1 according to the invention in a side view.
- the optical axis O is perpendicular to the x-axis.
- five illuminants Lm 5, 6, 7, n, 1 are shown by way of example in the illustration.
- the illuminant axes Lma 5, 6, 7, n, 1 of these luminous means Lm 5, 6, 7, n, 1 each include angles ⁇ 5, 6, 7, n, 1 of approximately 45 ° with the optical axis O.
- values between 30 ° and 60 ° have proved suitable for the angle ⁇ 1,..., N.
- a value of ⁇ 1, ..., n of about 45 ° has proven to be particularly advantageous.
- Values for the angle ⁇ 1,..., N which are outside the range of 30 ° to 60 °, lead to a significant deterioration of the imaging results obtained with the monitoring camera 2 or the image obtained.
- FIG. 3 shows a standardized representation of the illumination intensities achieved by means of the illumination device 1 according to the invention in the surveillance area or monitoring space in front of the illumination device 1 along the optical axis O and the x and y axes.
- the angle numbers on the semicircle correspond to the respective spatial direction.
- An intensity curve 7 shown in solid lines reflects the intensity distribution of the radiation which is usually achieved with known illumination devices in which the illuminant axes are aligned parallel to the optical axis O of the camera.
- the spatial intensity distribution of the radiation in the room results from a rotation of the intensity curve 7 about the optical axis O, so that the overall result is a "club-shaped", spatial intensity distribution.
- the height extent of the curve 7 in the direction of the optical axis O is a measure of the intensity of the radiation in this area. At the angle number of 0 °, the intensity curve 7 intersects the optical axis O. At this point, the radiation intensity reaches a maximum. For comparison with the intensity curve 7, an intensity curve 8 resulting using the illumination device 1 according to the invention is shown dotted.
- the lighting device avoids only one-time illumination of one in the area of the optical Axis O located receiving object within the surveillance area or the monitoring space, in known embodiments of lighting devices to locally undesirably high contrast differences of the generated image leads.
- An overexposure of, for example, in less Removal takes place in front of the surveillance camera located face of a person Not.
- the surveillance area or the surveillance space becomes more uniform Illuminated by means of the illumination device 1 according to the invention.
- the Surveillance camera 2 therefore generates a surveillance image with one over the entire picture area good contrast. Especially objects and details, located outside the center of the image or away from the optical axis O of the surveillance camera 2 are shown much better.
- the won Images can be easier manually or with suitable image processing algorithms - For example, for automated image recognition, for automated access control or the like - evaluated and edited.
- the lighting device Of course, 1 must comply with the geometry or condition of the monitored object Room or area are adjusted. The adjustment takes place as described above in the individual case by the appropriate choice of the number and type of lamps, their radiation intensity, their radiation characteristics and their orientation in space with respect to the optical axis O (angle ⁇ , ⁇ ) of the Security Camera 2.
- FIG. 4 shows a test image taken by means of a known illumination device with an infrared surveillance camera.
- FIG. 5 shows a test image which was produced using the illumination device 1 according to the invention and an infrared surveillance camera.
- the contrast of the test pattern in FIG. 4 is in the border region between the facial plane of the person depicted and the background though slightly higher than the contrast of the image of FIG. 5 in total.
- Objects and details that are outside the center of the image of the test image in FIG. 4 are difficult to recognize because of the contrast to the edge of the image as a result of the punctual overexposure of the monitoring area or the interstitial space along the optical axis O of the surveillance camera 2 rapidly decreases (see Fig. 4).
- the more uniform contrast distribution allows over the total area of the test image of Fig. 5, a better evaluation of the image content across the total area of the image.
- An overexposure of the center of the picture is avoided by the illumination device 2 according to the invention.
- objects and details that are outside the center of the image of the test image of FIG. 5 are rich in contrast, therefore rich in detail and thus easy to evaluate played.
- obtained images can be thus manually or by automated image processing algorithms, for example for image recognition or for verification of access permissions, better evaluate.
- potentially dangerous, dangerous Objects and details clearly visible outside the picture center displayed.
- Areas of application for the lighting device according to the invention are under other passenger cabins, luggage and cargo areas in aircraft, passenger doors in airplanes, as well as cockpit doors in airplanes.
- the lighting device according to the invention is not, however, to the application in the field of civil and limited to military aviation. Conceivable are applications in other security relevant Areas such as indoor surveillance, the surveillance of external surfaces of buildings or the like and the Control of occupied areas of passengers in transport facilities of the public local and long-distance traffic.
- the light sources Lm 1,..., N of the illumination device 1 according to the invention have infrared light emitting diodes (IRED) in the case of using an infrared surveillance camera, which is particularly sensitive to radiation in the near infrared range of the electromagnetic spectrum.
- IRED infrared light emitting diodes
