摘要:
A method and apparatus for automatically and continually feeding workpieces, one after another, to a sewing machine. The continuous feeding is imparted to the workpiece by a plurality of connecting links which connect the trailing edge of one workpiece with the leading edge of the following workpiece at a point in front of the sewing instrumentalities. The workpiece that is being fed into and through the machine automatically draws the succeeding workpiece towards and through the machine due to the connecting link fastening these two together. Motion is imparted to the connecting links by the feed device associated with the sewing machine. The connecting links are guided through a predetermined path by a rail system which automatically returns the connecting link to a staging area after same has been released from the workpiece. A sewing machine fastens together the continguous ends of the workpieces and a cutter cuts the chain formed therebetween.
摘要:
Fabric lengths are monitored during and/or prior to sewing by sensing means in conjunction with a logic system. Differences in fabric ply lengths are compensated for by the logic systems control via stepping motors of the differential feed assembly located above and below the fabric plies.

A lane monitoring method for a vehicle includes: detecting a lane of the vehicle with the aid of a camera of the vehicle; recording driving status measuring signals of the vehicle; evaluating the driving status of the vehicle according to at least one lane departure criterion; upon meeting the lane departure criterion, checking whether decision criteria for detecting an intentional trajectory shortening maneuver have been met; and generating a lane departure warning signal as a function of the evaluation according to the lane departure criterion, the output of the lane departure warning signal being suppressed if an intentional trajectory shortening maneuver is detected.

A driver-assistance system for a motor vehicle includes a recording device for recording an environment of the motor vehicle including a rear environment of the motor vehicle, a warning device for generating a warning signal, and an evaluation device. The evaluation device is configured to analyze a current driving behavior of the driver on the basis of the recorded environment of the motor vehicle, and to induce the warning device to generate a warning signal if the evaluation device detects a deviation of the driving behavior from a predetermined setpoint behavior.

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.
摘要:
A method for recognizing road signs in the vicinity of a vehicle and for synchronization thereof to road sign information from a digital map where, in the case of a recognition of road signs, road-sign recognition data are generated, navigation data being provided for localizing the vehicle in digital map data, and the road-sign recognition data being synchronized to the map data. To be able to provide unambiguous and the most accurate possible and thus improved road sign information to be output to the driver in the context of such a method, in the case of a discrepancy between the map data and the road-sign recognition data, the decision is made with the aid of reliability factors for the camera and map as to whether the data from the digital map or the road-sign recognition data are output in the vehicle.

A method for processing data, including the recording of raw data, processing, particularly digitizing, compressing and/or encoding, the raw data, analysis, particularly performing a content analysis, of the raw data or the processed data, interpretation, particularly performing an event recognition, of the analysis results in order to generate a semantic description of the contents, indexing of the processed data with the aid of the semantic description, processing of the indexed data. A data-processing system having a recording device for recording raw data, at least one processing device for the processing, particularly digitizing, compressing and/or encoding, of the raw data; for interpreting the analysis results, particularly for performing an event recognition in order to generate a semantic description of the contents; and for processing the indexed data; an analyzer device for the analysis, particularly for performing a content analysis, of the raw data or the processed data, and an indexing device for indexing the processed data with the aid of the semantic description. This method and this system provide improved data processing, especially of audio data and/or video data.

The invention relates to a security system 100, having a camera 3 for taking pictures of objects. From chronologically successive pictures taken by the camera 3, a gray variance [variant term] of the pixels is derived, which is compared with a threshold value that is dependent on the gray value. This improves the recognition accuracy of the security system 100.

In a method and an apparatus for generating a depth map of a scene to be recorded with a video camera, the scene is recorded at a plurality of focus settings differing from one another, and the focus setting proceeds through the depth range of the scene in increments; the image components recorded in focus at a given focus setting are assigned the depth corresponding to that focus setting, creating a first depth map; the scene is recorded a plurality of times, each at a different zoom setting, and from the geometric changes in image components, the depth of the respective image component is calculated, creating a second depth map; and from the two depth maps, a combined depth map is formed.
