Definitions
- the invention relates to a method for non-lethal action on at least one target object, wherein at least one active body is fired by a launching device. Furthermore, the invention relates to a device for non-lethal action on at least one target object, comprising at least one active body for acting on the target object, a device for accelerating the active body and a control unit for controlling a dependent before an effective distance to the target object kinetic launch energy of the active body ,
- the DE 199 25 864 C1 describes a projector of conventional type for mounting under the barrel of a rifle and for firing a cartridge.
- the kinetic energy of a shot active body is distance-dependent, ie directly at the mouth of the active body has a maximum kinetic energy, with the result that at a very short target distance a lethal effect of the active body is possible; at a greater distance, on the other hand, the kinetic energy of the active body has decreased so much that virtually no possibility of influencing people is given.
- Conventional throwers like from the DE 199 25 864 C1 known, are also operated with factory-backed ammunition, as for example from the DE 197 38 937 C2 is known. Such ammunition does not allow deployment-related approximation of kinetic energy in terms of target and distance.
- Previously known lethal launchers such as mortars, howitzers, or the like, allow incremental distance adjustments (by altering the launch angle), but the adjustment options are several orders of magnitude above the non-lethal range of interest.
- the charging process in such devices does not allow adjustment of the kinetic energy, due to the intended lethal effect is not at all desirable.
- Target object may be any object to be hit by a non-lethal active body, in particular persons or animals.
- the active body strikes a strong target object with too low energy, while it can hit with too great an energy in the case of slender target objects, which can lead to unwanted further damage to the target object.
- the invention is therefore based on the object to avoid such disadvantages.
- the invention initially provides in a method of the type mentioned that constitutional data of a target object are detected, which may be provided to solve a subtask alternatively or additionally, that at a certain time, the image of a target detected at and To shoot down the active body successive changes in the image over predetermined tolerance limits addition, a shooting of the active body is prevented.
- a generic device for solving the above task is characterized by an image capture device.
- the kinetic energy of the active body is determined in consideration of the distance from the launcher to the target object according to the constitution-determining or constitutional characteristics, ie constitutional data, in which case a firing of the active body is prevented, in particular for constitutional data lying outside predetermined limits.
- the determination of the available energy to be applied to the active body and thus its kinetic energy with respect to the detected target position can in particular be done such that the measured constitutional data are compared with values from a table with supporting data, by means of an algorithm or a mathematical function of specific values ,
- a device according to the invention is configured accordingly in a preferred embodiment.
- Another embodiment of the invention provides that when initiating the launching process the image of the target person recorded and monitored until the shooting of the active body.
- the device according to the invention provides an image acquisition device in a first development.
- a first device for determining constitutional data of a target object may further be provided, such as size or stature of the target object, wherein in particular the control unit is designed to control the kinetic firing energy of the active body taking into account the constitutional data.
- shot corridor refers to the given when targeting the target object for the operator free space within which a desired action of the active body takes place on the target object, ie the sum of the possible paths of the active body, starting from its launch position to the desired action on the target object.
- Spatial freedom of the protection corridor means that there is no object in it is not to be hit, which is referred to as a prohibited target (prohibited target). So there is an active body delivery only in free field of fire.
- the detection of the target object is effected by an image capture device, wherein constitutional data of the same can be determined by an evaluation device on the basis of the acquired image of the target object, such as size, width and also detected surface of the target position. From this it can be determined whether the target position is a strong or a slender target object and accordingly, taking into account the co-determined distance to the target position, the active energy acting on the active body and thus the kinetic energy of the active body are specifically determined, so that this the target object hits with a kinetic energy that sets the target object "out of action" without causing too much consequential damage.
- the trigger can be blocked if detected constitution values are outside predetermined ranges, for example, a lower limit value can be specified for the detected variable, below which the shoot of the active body is blocked, so that, for example, children are not shot become. Determining the area of the person detected by the image-capturing device and a lower limit also given for this can preclude the shooting of small and slender persons, whereby different constitutional data and the criteria to be applied can be combined with one another.
- the comparison of the image capture device between a first time, for example, the time of triggering the provision of the kinetic energy for the active body detected target position, with later recorded Images in the range of the target position makes it possible to determine whether the captured image changes significantly, for example, because a person runs into the intended trajectory of the active body, whereupon the launching process can also be canceled.
- a comparison device can be used to compare the image streams of two or more image capture devices which are located at different positions.
- the distance to a target object can be calculated by means of such a comparison.
- a method may involve deriving the distance of the target object using the beam set from the perspective measured offset of the two image capture devices and the known distance of the image capture devices.
- Such a "passive" distance measurement by image processing is characterized in particular by freedom from emissions of an energy or a medium required for carrying out the measurement, such as a sound or electromagnetic wave, and has a conventional "active" distance measurement, for example by means of a laser beam reflected at the target object , numerous advantages.
- a location of the operator at the position of the target object by the measuring medium and a harmful action of the measuring medium on the target object, for example a possible damage to the eyesight of a target person by a laser beam is prevented.
- the distance measurements carried out are independent of the reflective properties of the measuring medium on the target object, so that distances to target objects can be measured, which are not accessible, for example by laser or Radarmess vide.
- a distance-adapted insertion of a target auxiliary token for the operator can continue to take place, such as a crosshair.
- a situation-adapted insertion of other auxiliary information in the field of view of the operator can also be provided, for example information about the target distance.
- the image streams detected by one or more cameras can also be used to improve the visual field of the operator.
- an electronic image processing of one or more individual images of the camera (s) takes place, in which by means of suitable algorithms or methods, obstructive influences, such as e.g. Smoke, haze, mist are removed.
- obstructive influences such as e.g. Smoke, haze, mist are removed.
- Such a method may comprise, for example, a separate processing of the raw images acquired by the individual RGB channels of the camera, which are subsequently combined to form a result image.
- Such a calculated optically higher-quality image stream allows the operator to securely identify target objects that are difficult to recognize for the human eye.
- possibilities for night vision can be implemented for the operator, e.g. Low light amplification or infrared view.
- the image streams of one or more cameras are recorded. These can then be used, for example, for training purposes on the launcher.
- Fig. 1 shows schematically the application of a device according to the invention in the form of a launcher for non-lethal exposure to an object in the form of a target person B by an operator A.
- a conical shot corridor D determines the crowd of possible throw or shot lanes, by means of an active body can be effectively acted on the target person B.
- a selected throw or trajectory C lies within the corridor D, which is detected according to the invention by suitable image capture devices.
- this shot corridor D is particularly ensured that the trajectory C of the active body can be made only in the direction of exposure to the target person B, but not in the vicinity of persons E1 or E2.
- there is a temporal monitoring of the shot corridor D before delivery of the active body so that occurs when entering in the vicinity of the shot corridor D persons E3 in the same a shot closure.
- step 2 An inventive method for providing the described functions is shown in Fig. 2 in a flow chart.
- step 1 the firing is blocked (step 2) and image data of the target person B are acquired by the image capture device (s) (step 3), which are then further processed in a suitable image processing device (step 4 ).
- step 4 the acquired image data or results and operating processes can be stored (step 4a) and / or the resulting images and results are displayed (step 4b).
- setting of the shot energy step 5 is performed depending on the data obtained in the image data processing, e.g. the removal or constitution of the target person B.
- step 6 a verification (step 6) is carried out as to whether the process should be continued or aborted (step 10). If firing is desired, the results of image processing are e.g. with regard to monitoring of the shot corridor D (step 7). If a prohibited target is detected within the shot corridor, the process continues with the re-acquisition of image data (step 3). If, on the other hand, firing is possible on the basis of the data recorded in the image processing, it is further checked whether the operator has actuated the trigger for triggering the shot (step 8). If so, the shot is fired (step 9) and the process continues again with the blocking of another shot (step 2).
- step 4 The method steps according to the invention for image data processing (step 4) are shown in FIG. 3 in a flow chart.
- step 4.1 After initiating further processing of the acquired image data (step 4.1), initially obstructive environmental influences are removed therefrom (step 4.2) and distance measurements to the target object (step 4.3).
- step 4.2 After a query as to whether they are within a valid range, the shot corridor is analyzed in the following process steps (step 4.4) and the constitution data of the target person B are analyzed, in each case with a subsequent query as to whether they are within the intended range. If one or more of these three range queries are negatively evaluated, it will not be possible to fire a shot (step 4.5b). Only with positive evaluation of all three range queries is a firing possible (step 4.5a).
- step 4.6 After completion of the image processing (step 4.6), the method is continued with the setting of the shot energy as a function of the data determined in the image data processing, as described.
