Abstract:
A device for classifying at least one object in the surrounding field of a vehicle with the aid of an environmental sensor system, the device classifying the at least one object on the basis of its shape and its dimensions, and the environmental sensor system ascertaining the dimensions.
Abstract:
A measuring device for a heat exchanger includes a heat exchanger pressure pipe having a pipe wall with a circumference, and an indentation extending over and deforming a portion of the circumference. At least one thermocouple is disposed eccentrically in the portion of the circumference deformed by the indentation. Filling material fills the indentation. A method for producing a measuring device in a pressure pipe of a heat exchanger, a method for monitoring an operating state of a heat exchanger having a pressure pipe, a heat exchanger, and a method for measuring a heat flux, are also provided. The size of the indentation can be decreased for a given size of the thermocouple due to the eccentric configuration of the thermocouple, so that the heat flux is obstructed to a comparatively small degree by the pipe wall while local overheating of the pipe wall is prevented.
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 camera system, e.g., for a vehicle, includes: at least one objective for detecting a detection region, one image sensor for outputting image signals, and one auxiliary optics situated in the detection region, the auxiliary optics together with the objective forming an optical imaging system for imaging a two-dimensional detection region on the image sensor. The auxiliary optics is formed by one auxiliary lens having an entrance surface and an exit surface, and the two-dimensional detection region does not extend vertically with respect to the optical axis of the auxiliary lens and is imaged sharply on the image sensor by the optical imaging system. The entrance and exit surfaces do not have a spherical curvature.
Abstract:
A method for assisting a user of a vehicle, in which driving-condition variables (v, a, q, ω, n) are sensed or ascertained via sensors of the vehicle, and a camera of the vehicle covers a coverage area of a road scene at least in front of the vehicle and outputs image signals. Based on the image signals, it is determined whether a further vehicle which is outputting blinking signals is in the coverage area. As a function of the ascertained driving-condition variables (v, a, q, ω, n) of the vehicle and as a function of the determination as to whether other vehicles are indicating a change of direction, information signals, particularly warning signals, are able to be output to the user and/or an automatic driver-assistance control is able to be implemented in which control signals for interventions in a vehicle control for a longitudinal control and/or lateral control, especially a distance control, are output. In this context, in each case different possible control interventions are able to be ascertained and carried out. Furthermore, a corresponding control device and the vehicle thereby made possible are provided.
Abstract:
A method for determining an ego-motion of a vehicle is described, which is carried out in driver assistance systems, particularly in parking assistance systems. The method involves: taking a sequence of images, successive in time of a vehicle surroundings by a vehicle camera; determining, based on the image sequence, at least one motion flow with regard to an object in the vehicle surroundings; and determining the ego-motion of the vehicle based on the at least one motion flow.
Abstract:
In a method for displaying an image of a scene in front of a vehicle, recorded by a video camera, in which the scene in front of the vehicle contains a roadway which is illuminated by the vehicle's headlights, the gray values of the pixels of the image data generated by the video camera are weighted using a reduction factor, which is a function of the respective pixel within the image and of the brightness of objects in the near range in front of the vehicle, in such a way that the contrast between the display of the near range in front of the vehicle and the display of other parts of the image is reduced.
Abstract:
A method for detecting an interfering object in a camera image of a camera image sequence includes: reading in a first pixel data value of a predetermined position in a first camera image obtained at a first point in time, a second pixel data value of the predetermined position in a second camera image obtained at a second point in time after the first point in time, and a third pixel data value of the predetermined position in a third camera image obtained at a third point in time after the second point in time; ascertaining a reference value on the basis of the second pixel data value and a comparison value on the basis of the first pixel data value and/or the third pixel data value; and detecting the interfering object at the predetermined position when the reference value is in a predefined relationship with the comparison value.
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.
