摘要:
Video monitoring systems are commonly used for monitoring streets, junctions, squares, and also public buildings, museums, prisons. Video monitoring systems which output the results for the viewing areas/objects in the scene in metric units, such as lengths in meters and speed in meters per second, or the absolute and/or relative positioning in a camera network, require knowledge of camera parameters such as e.g. the position, orientation, and aperture angle of the camera(s). These parameters are usually manually measured at high cost during the installation process, for example special patterns (sample patterns) are used, or people walking backwards and forwards in front of the camera. A monitoring camera 1 is proposed, according to which the monitoring camera 1 is positioned and/or can be positioned for monitoring at a stationary monitoring position, with a calibration aid system 5, wherein the calibration aid system 5 is designed for determining the stationary monitoring position of the monitoring camera.

A system and method to record the surroundings for a movable device. The system has at least one sensor for the visual recording of the surroundings, as well as respectively at least one sensor for recording the direction of motion and the orientation of the device, the system being developed to process information provided by the sensors.
摘要:
A method for controlling the drive-off of a motor vehicle in which the area in front of the vehicle is sensed using a sensor device and a drive-off enabling signal is automatically output after the vehicle stops, if the traffic situation allows. Features of the road in the area in front of the vehicle are extracted from the data of the sensor device, and on the basis of these features, at least one enable criterion is checked, a positive result indicating that the road is clear.

A blind spot detection system. The system includes a camera mounted at the rear of a vehicle, a controller coupled to the camera, and an indicator coupled to the controller. The camera is configured to capture images in a field-of-view to the rear of the vehicle. The controller is configured to receive a signal from the camera indicative of the images, and controller determining when a second vehicle in the images enters a blind spot of the vehicle. The controller activates the indicator when the second vehicle enters the blind spot of the vehicle.

A chassis testing unit (2) according to the present invention, in particular a shock absorber testing unit, for a vehicle on a test set-up (4) includes at least one correlation sensor (14-18), having an associated lens, situated at the side of the test set-up (4). The correlation sensor (14-18) is directed toward the test set-up (4), and is designed to detect a time sequence of images of a section of a motor vehicle (6), in particular of the body of the motor vehicle (6) and of the motor vehicle wheel, moving on the test set-up (4), and to determine directional velocity components therefrom. The chassis testing unit also includes a data processing unit which is connected to the correlation sensor or correlation sensors (14-18), and which is designed to determine the motion of the motor vehicle, in particular of the body of the motor vehicle (6) and of the motor vehicle wheel, on the basis of the directional velocity components of the correlation sensor or correlation sensors (14-18).
摘要:
A method for processing image data of two sensors of a stereo sensor system that are suitable for recording images, each of the sensors being configured to record the image data section by section in sensor sections of the sensor that are situated at different positions. The method includes providing information on a geometrical offset between the positions of two sensor sections of the first sensor and the second sensor which have corresponding image data, and reading out image information of the first sensor and image information of the second sensor, the reading out taking place with reference to the positions of the sensor sections, from which the image data are read out, using the offset.
