Abstract

PURPOSE:To automatically obtain the change of meteorological information by predicting the next position of a singular point from the time-series change information of said optional singular point obtained from meteorological satellite picture data, and displaying the predictive position together with the time-series change information on the same picture. CONSTITUTION:A meteorological satellite distributing signal from a satellite is stored in a picture memory 3, and is displayed on a display device 4 after acquisition time is set by an operating part 5. When the singular point related to a target cloud is designated, the picture plotted by a designated position plotting part 6 as the locus of the singular point at every point of time is written in the designated picture in the picture memory 3, and the set of position information and picture data is stored in a data memory 7. Such processing is repeated by the number of times of the portion of the number of sheets to be used, and the next predictive position is obtained by a predictive position calculating means 8 by using the data read out from the data memory 7. The position information stored in the data memory 7 and the predictive position obtained from the predictive position calculating means 8 are plotted on the latest picture by a designated position plotting part 9, and are displayed on the display device 4. Thus, meteorological prediction can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for predicting and displaying meteorological image data, and in particular to analysis processing of meteorological satellite image data distributed by meteorological satellites, such as predicting singularities in cloud images. Change the processing display method.

(Prior technology) Conventionally, image display from meteorological satellites has been performed by continuously displaying already obtained meteorological images over time in order to visualize temporal changes and movement of atmospheric phenomena for the purpose of weather forecasting, etc. It was displayed.

(Problems to be Solved by the Invention) In the conventional continuous display of existing weather images described above, only past cloud flows are displayed, and in order to make weather predictions from this past data, an observer must It has the disadvantage that analysis processing must be performed using the information, and that display on the same display screen and numerical data cannot be automatically obtained.

(Means for Solving the Problems) A method for predicting and displaying meteorological image data according to the present invention receives meteorological image signals at multiple time points from a meteorological satellite, and extracts meteorological singular points from the received image signals. do,
Find time-series position change information of the singular point, predict the predicted position of the singular point at the next time point based on the position change information, and display the time-series position change information and the predicted position information on the same screen. displayed at the same time.

(Example) Next, a prediction processing method for weather image data according to the present invention will be described with reference to the drawings.

In this embodiment, the case where the movement of clouds is tracked as the target weather information is taken as an example.

As for the tracking cloud selection (cloud specification) method, the first method is to select an appropriate one while looking at the image (manual selection of FIA clouds).
There is a second method (fully automatic method) in which a computer selects images based on certain criteria without inspecting the images.

First, Part 1 (A) shows the configuration block diagram of the first method.
Referring to , a meteorological satellite distributed signal from a satellite is captured by a meteorological satellite distributed signal receiving antenna 1, received and demodulated by a meteorological satellite distributed signal receiving section 2, and then stored in an image memory 3.
is stored in This image memory is a VRAM, as shown in Figure 1 (
The configuration shown in B) is adopted, and data is stored sequentially. In the first part (B) + 1.2, 3. ..., n is each time point, 1, 2, 3, . ...indicates image data at n.

When the acquisition time is set from the operation unit 5, it is displayed on the display 4. When a singular point regarding the target cloud is specified while viewing the display screen of the display device 4 from the outside, the specified position plotting section 6 writes the image plotted as the locus of the singular point at each time point into the specified image in the image memory 3. It is displayed on the display 4. At this time, in order not to damage the image data, a combination of position information and image data is stored in the data memory 7. This process is repeated for the number of images to be used (image data for the usage time point), and then read out from the data memory 7. The predicted position calculation section 8 calculates the next predicted position using the data (abbreviated as prediction process A).

Position information stored in data memory 7 and predicted position "J"
The predicted position obtained from the i calculating means 8 is plotted in the specified position plotting section 9 (the latest of the used data) and displayed on the display 4.

A system block diagram of the second fully automatic method is shown in FIG. The process up to storing the received data in the image memory 3 is the same as the method in Section 1 above. The memory configuration should be the same.

If you input the acquisition time, number of data sheets used, singularity, etc. from the operation vlS and set the processing command setting section 10''C-,
A designated image (assumed to be stored in part n of the memory) is displayed on the display 4. At the same time, the pattern setting section 11 sets a pattern including the singular point, and the pattern detecting section 12 detects the pattern set by the pattern setting section 11 from among the image data for n-1 stored in the image memory 3. (Pattern detection processing is abbreviated as B)
.

The singularity detection unit 9 detects the singularity from the undetected pattern (
The singular point detection process is abbreviated as C), and this is stored in the data memory 14.The same process is specified thereafter, such as detecting the image pattern for the 0th order n-1 from the image for n-2. The predicted position calculation unit 15 executes the prediction process (A) for calculating the predicted position by executing it for the number of schools.

These singular points are plotted on the image and displayed on the display 4.

(Effects of the Invention) As explained above, the present invention predicts the next position from time-series change information of any singular point obtained from meteorological satellite image data, and displays the predicted position together with the time-series change information on the same screen. By displaying the information above, changes in weather information can be automatically obtained in an easy-to-understand manner, and weather forecasting can be simplified.
