Abstract:
Classification methods are described that proceed in computer-assisted fashion, and in particular a method for evaluation and stabilization over time of classification results is described in which objects to be classified are sensed using sensors over a period of time, and are repeatedly classified with the inclusion of specific quality parameters for each object class. To ensure better classification reliability, the following steps may be carried out: a) increasing the value of the confidence parameter if a subsequent classification confirms the result of a previous classification; b) decreasing the value of the confidence parameter if a subsequent classification does not confirm the result of a previous classification; and c) generating a final classification result including the confidence parameters that have been increased or decreased in value.
Abstract:
A water lance blower for cleaning heating installations, wherein a water lance (6) is movably (5) arranged with its mouth on or in a hatch (2) and can blow a water jet through the heating installation, which is in operation and is flowed through with flames and/or smoke, onto wall areas (A-E) which can be reached from the hatch (2), wherein the water lance (6) is movable by at least one movement element (8.1, 8.2, 8.3) which is stationarily fixed at one end outside a vertical plane through the point of movement (5) of the water lance (6) to the heating installation and by the other end (7.1, 7.2, 7.3) to the water lance (6), wherein path sensors are provided for precise determination of the position of the water lance (6). Preferably three movement elements (8.1, 8.2, 8.3) are provided, the fixing points (9.1, 9.2, 9.3) of which each form in particular an angle of approximately 80° to 140° to the point of movement (5) of the water lance (6). Such water lance blowers can be installed even when there are unfavorable spatial conditions and perform any freely pre-determinable blowing patterns and speed profiles.
Abstract:
A method for recognizing directional structures on a window pane of a vehicle is described. The method includes carrying out an assessment of image points of an image of the window pane, which image points are disposed along an evaluation path, a course of the evaluation path being dependent on an expected orientation of the directional structures on the window pane. The method further includes recognizing a directional structure based on the assessment.
Abstract:
A method for ascertaining image signals having color values and a camera set-up, which has: a camera having camera optics, an image sensor for recording an environment and for outputting first image signals, and a color mask applied in front of the image sensor, and an evaluation device, which picks up the first image signals emitted by the image sensor, the image sensor having a plurality of sensor pixels and the color mask having a plurality of filter pixels which are each situated in front of the sensor pixels and include first colored filter pixels and transparent filter pixels; and some of the sensor pixels picking up the light via the colored filter pixels and outputting the first color values, and additional sensor pixels picking up the light via the transparent filter pixels and outputting the intensity values. The evaluation device ascertains second color values from the intensity values and the first color values of various sensor pixels, and forms second image signals from the first color values and the second color values.

Abstract:
A method for determining an accident risk of a first object with at least one second object is proposed, a collision probability and a hazard probability of the at least one second object being determined in a predefined region around the first object, the collision probability and the hazard probability being determined as a function of motions and object classes of the first and the at least one second object. The accident risk is then determined as a function of the collision probability and the hazard probability.
Abstract:
A bearing system for a water lance of a water lance blower contains a ball joint having a ball with a surface and a diameter. The ball further has a passage, on and/or in which the water lance can be disposed. The bearing system is characterized in that a ball seat is provided and contains two axially interspaced bearing shells each of which has an opening, whereby the ball protrudes at least partially into the openings. A method for operating the bearing system that seals gaps, which can occur as the ball rotates, between the surface of the ball and the spherical contact surface of the at least one bearing shell. The bearing shells enable the bearing system to be easily assembled, and the small contact surfaces reduce the amount of friction during operation. In addition, the bearing system is also suited for use as a seal.
Abstract:
A water lance blower for cleaning heat installations is disclosed. A water lance linked with a water feed conduit system is swivel-mounted with its orifice disposed in a hatch. The water lance can blow a jet of water through the heating installation in operation and through which flames and/or flue gases are guided to wall areas that can be reached from the hatch. The water lance blower is provided with a drive system with at least two drive units that control the water lance, and with a holding device that fastens the water lance blower onto the heating installation. Further, parts of the water feed conduit system are integrated onto the holding device, thereby substantially limiting the size of the water lance blower to the swivel range of the water lance.
