Definitions
- the invention relates to a method according to the preamble of the main claim.
- Such a method is known from WO 02/103292 A1 in a flight guidance display, which serves the screen display in particular of safety-related or otherwise function-critical sensor data, which drive according to their signal processing technical preprocessing to graphic instructions a graphics generation.
- Such a graphic generation of the video data from the graphic instruction for the current image representation extends, for example, to geometric transformations such as the transition between different coordinate systems and to image filtering such as interpolation processing of the video signal sequence for smoothing the visual elements finally to be presented visually and their changes in the successive images.
- the graphics generation is therefore very complex and correspondingly error-critical.
- certain graphics instructions are compared with the result of the graphics generation as to whether the video signal still contains the original graphics instruction.
- the graphics generation must be undone mathematically. This requires an extremely high cost of expensive since particularly fast-working computer architectures, because yes to control individually picked out video data parallel to the screen to control. Inevitably, this complexity of the control mechanisms results in a certain susceptibility to error, which then can simulate actually nonexistent malfunctions in the acquisition of the video data.
- the present invention is based on the technical problem underlying a less complex and therefore more resistant to interference. Realize the generation of video data, with less computational power required for this simple control function.
- Graphic instructions preprocessed raw data such.
- the video data generated from the test vectors expediently control no pixels in the image representation, but areas of the screen that are not the current image representation. For example, they are located in a currently informal square of the display or better still on the edge under the built-in frame in order not to burden the current image display with mere test impressions. It is even preferable to filter out these test-relevant video data from the result of the graphics generation and thus to completely separate it from the video data for the screen control. This is possible because of the well-known law when generating the Testvektor- ren by means of a dedicated logic before the screen control without much additional effort.
- test vectors can be fed in instead of the graphics instructions prior to the graphics generation or additionally with the raw data prior to the data preprocessing.
- This upstream data processing to translate the raw data into graphics instructions is also very complex. It includes, for example, a limitation of the useful spectrum in the raw data and its scanning for the digitization taking into account a band limitation to ensure perform the sampling theorem, further integral or differential filtering to influence the signal dynamics, or non-linear gain and scaling to avoid data loss in noise as well as due to overdrive.
- test vectors pseudo-stochastic signal sequences of defined lengths are expediently selected here, as can be generated simply and clearly reproducibly by apparatus, for example, by feedback shift registers or corresponding small processor programs. These test vectors are then subjected to the same complex signal preprocessing prior to the geometric transformation and image filtering in the graphics generation as the sensor data.
- the stochastics of the test vectors are not influenced by the signal processing, so that the test vectors can be compared directly with the video data obtained therefrom by cross-correlation. This eliminates the otherwise very large kaustechische additional effort alone for fast recalculation of the video data on their source information: From the intensity of the convolution product results directly, if any malfunctions have occurred in the course of signal processing. It is expedient to generate differently designed test vectors, which are optimally adapted to certain critical signal processing operations, in order to be able to obtain particularly meaningful correlation results.
- the sole figure of the drawing illustrates a basic block diagram abstracts the feeding and querying of test vectors for continuous monitoring of the current video image obtained from raw data.
- the raw data flowing into a visual representation after signal processing in the form of sensor data 11 of a plurality of sensors for monitoring functional or safety-critical conditions are processed in a data processor 12 by a pre-processor.
- a data processor 12 To obtain a block of graphics instructions 13 at the output of a converter 14.
- the vectors of these graphics instructions 13 feed a graphics generator 16 of low cost, industry standard (such as Open Graphic Language) operation.
- the visual representation is driven on the screen 19.
- a test generator 20 supplies an externally definable test vector 21, which is superposed in the converter 14 to the sensor-dependent graphics instructions 13.
- the numerous very different functions of the graphics generation adapted, so assigned to different test vectors 21.
- test vector 21 information from the test vector 21 should not appear on the screen 19 in order not to disturb the actual visual performance of interest.
- the test vectors 21 can therefore not be used for presentation, especially under
- a so-called dedicated or assignment logic 22 is provided for the video data 18.
- it is set up to separate out the test vectors 21 'contained in the video data 18, so that the screen 19 is acted upon with video data 18' which has been cleaned up by the mere test vectors 21 ', ie images based on sensor data 11 only presents.
- the option is indicated by dashed lines, the test vector 21 (in addition or at all) already in front of the graphics generator 16 in the signal flow ein- If the laws of this preprocessing is taken into account for the function of the comparator 23, not only the image generation is monitored, but already the preprocessing of the supplied sensor data 11 to the image generation, because de test vectors 21 as in the graphics generator 16 already in the data processor 12 for the preprocessing of the pending critical sensor data 11 each undergo the same processing path, so are subject to any error influences.
