Abstract

The invention pertains to measurement technology and can be used in object identification systems used for various purposes. First, the displacement step of the scanning sensor is selected on the basis of the smallest object elements which must be fixed, the scanning time, level of scanning reliability required, etc. The scanning process starts from a point (3) selected at random on the object (2). In the area (4) surrounding that point (e.g., in the form of a circle), the direction (1) of displacement of the scanning sensor is defined corresponding to the direction onto the point on the boundary of the said surrounding area, with the greatest possible change in the scanned parameter relative to its value within the point (3). Linear displacement of the scanning sensor from point (3) is done in the chosen direction with pre-set steps (t). Once each step is completed, the value of the scanned parameter value is measured and compared with the value within the point (3). If the difference between them does not exceed the reference value, the sensor is displaced by one more step in the selected direction. If the difference between the parameter values exceeds the reference value, displacement of the scanning sensor in the selected direction is interrupted and the scanning direction redefined. Scanning is stopped when the volume of information on the scanned object is found to be insufficient for its identification.

It is worth noting that a known method is very advantageous at a time and does not allow the process to be scanned dependently on the process. 20 ΡΑCΚΡΚΡΤΤΕ ΕΟΟΡΕΤΕΗΡΕΤΕΗ.

The task solved by the present invention is to expand the technical capabilities of the system, to increase the availability of scanning.

The solution to the problem is ensured by the fact that, in the process of scanning the object, when it is handled, there is a direct scanning of it with

The method allows the scanning process to be optimized, as well as to increase the volume of information used in the research. 10 The essence of the method is explained in Fig. 1.

Initially, select the move step of the sensor, which measures the 15th elevation of the terrain. The step is chosen, as a rule, proceeding from a whole series of factors: the minimum dimensions of the element of the relief; There is a method of direct access to the sensor in a specific direction of 20 (there are 1 scanning of the studied 2).

The scanning process starts from Part 3, which is selectively selected on the second page. Β The directly selected start-up process is off-site.

4 (for example, in the form of a circle) and the direction (vector) of the scan is taken out of this direction in the direction of the highest altitude, which is divided by

25 page of this area of the East is the main starting part.

The direct movement of the scanning user from the initial part is carried out with a predetermined step (I). At the end of each step, a measurement of the elevation of the terrain is made and the previous value is compared with the height of the relief at the initial point. If the difference between them does not exceed 30 the set value, then there is a movement of the sensor in the direction of scanning one more step. If there is a difference between the elevation of the relief in the initial and current scans of the scan, the set value is exceeded, in the current environment the closed \ УΟ 97/12203 ΡСΤ / ΙШ96 / 00327

Similarly, how is this done in the initial course. Further, the process is presented in a similar way as described above for the fact that the scope of the information is not acceptable for scanning, however, it is not acceptable for it. 5 The following is an example of a scan of a color image (cart), which is implemented by the following.

Takes a move step based on linear dimensions of the minimum element of the image, which is necessary to fix. The color value in each image is divided by the amplitudes of the pixels

10 of its basic colors (extra, green and blue). Based on the requirements for the measurement of the color of the image, the values of the changes in the amplitudes of the spare, green and blue circuits are selected. Selects the starting point for the image. Β her, and in every way

15 borders of its radial extremity, change color values. The distribution of the accommodation of the caterer is divided in accordance with the direction from the starting point to the border of the country and the radial contact with the maximum change in the color of the source. With the selected move step, in this direction, the color value is changed. And

20 Detecting a point, the color value in the short circuit differs from the color value in the initial point by an amount larger than the set value, the switch in this direction is not used. This dot is the initial new dot scan. The management of the accommodation of the user shares the same as described above. The scanning process is underway.

25 Information, the quantity of information obtained by the user, will not be sufficient for a stable recognition of the device with the given parameters.

The most convenient option for the expansion of the environment is its performance in the form of a circle. The value of the radius of extinction takes less than half

30 lengths of the previous scan (i.e., the values of the direct line of the scan sensor in the previous scan cycle). This avoids the occurrence of flammable transmissions near the points of local maximums or minimums of scanned parameters. \ УΟ 97/12203 ΡСΤ / ΚШ6 / 00327

If there are a few possible directions for scanning, select the first one you want.

The amount of change of the scanned parameter, if it is reached, the new scanning cycle starts, selects from the 5 limits for the duration of the scan. In order to exclude the possibility of other inadvertent accidents, a random operation is added to each cycle of scanning to it, which does not increase the incidence of accidents.

The size of the scanning step is selected based on the limits of 10 scanning times and linear dimensions of the minimum element, which must be taken into account.

The proposed method does not depend on the type of the scanned product, and due to the short time it pays for the quick recognition, the dynamic speed is 15%.

Disposal of the process is carried out by known hardware, which are not an object of the invention and are not a part of the application materials.
