2. Description of the Related Art A conventional apparatus for detecting a ground target using an observation sensor will be described. This conventional device performs ground target detection using an observation sensor mounted on a flying platform. FIG. 11 is a diagram for explaining the terrestrial imaging situation when the platform is an observation satellite. Observation satellites are typical of flying platforms. In the figure, 1 is an observation satellite equipped with a line sensor used for observation, 2 is the surface of the earth to be observed, 3 is a line sensor instantaneous visual field captured by the line sensor, 4 is the satellite traveling direction, 5 is the satellite Is an image capturing area imaged by the line sensor as the process progresses. FIG. 12 is a diagram showing an example of the configuration of a conventional apparatus that receives image data from an observation satellite and extracts and images a target from the received image data. In the figure, 6 is an antenna, 7 is a receiver, 8 is an analog-digital converter (hereinafter referred to as A / D converter) that converts received analog image data into digital image data, and 9 has a contact point a and a contact point b. A switch 10 is a first frame memory for storing digital image data, 1
Reference numeral 1 is a second frame memory that stores digital image data alternately with the first frame memory, 12 is a third frame memory, 13 is a target extraction filter, 14 is a target detection circuit, 15 is target position coordinate data, Reference numeral 16 is a reticle generating circuit, 17 is a reticle memory, 18 is a mixing circuit, 19 is a digital-analog converter (hereinafter D / A converter), 20 is an image display device, 21 is video data, 22 is target extraction image data, and 23. Is reticle image data, 24 is target image data, and 25 is display image data. This conventional device is installed on the ground.

Next, the operation will be described. In FIG. 11, the observation satellite 1 orbits the earth in the satellite traveling direction 4. Since the observation satellite 1 is usually equipped with a line scanning type sensor, the line sensor instantaneous visual field 3 scans the earth surface 2 as shown in the figure, and usually takes about 10 seconds for a predetermined frame scanning time to be shown in the figure. The imaging area 5 is imaged. For example, when the width of the line sensor instantaneous visual field 3 is 70 Km, 70 Km × 7 is obtained by scanning the range of 70 Km over a predetermined frame scanning time of about 10 seconds.
It is possible to obtain image information of a 0 Km square area as one frame. On the other hand, in the station installed on the ground,
As shown in (1), the image signal of the observation satellite 1 is obtained by the antenna 6 and the receiver 7, and this is A / D converted into the video data 21 by the A / D converter 8. The A / D-converted video data 21 is switched by the switch 9 at each frame scanning time, and is alternately recorded in the first frame memory 10 and the second frame memory 11. FIG. 13 is a diagram for explaining the relationship between the imaging area scanned by the line scanning sensor and the image information alternately stored in the first frame memory and the second frame memory. 101 and 1 in the figure
02 is a frame. Since the observation satellite 1 equipped with the line scanning type sensor orbits in the satellite advancing direction 4, the image information currently being scanned is in the process of forming the frame b shown in FIG. The frame a is the image information of one frame that has already been completed.

At the time when the switch 9 shown in FIG. 12 is connected to the contact a, the current scanning frame image, that is, the frame b.
Are recorded in the first frame memory 10. At the same time, the data of the previous frame image, that is, the frame a is read from the second frame memory 11 and input to the third frame memory 12 and the target extraction filter 13. As the target extraction filter 13, the extended spoke filter shown in the document “Sampling of Parallel Shape by Extended Spoke Filter, Technical Report of the Institute of Electronics, Information and Communication Engineers PRU88-10” by Sasakawa et al. Is effective for extracting a minute shape target by changing the filter parameter. It is possible to obtain the target extracted image data 22 in which the background such as a cloud is suppressed and removed. The target extraction image data 22 is input to the target detection circuit 14 to calculate the barycentric position of the target binary image, and the target position coordinate data 15 is output. The output target position coordinate data 15 is output to the reticle generating circuit 16. The reticle is identification information displayed over the target in order to assist the target judge in visual judgment. When the target position coordinate data 15 is input,
The reticle generation circuit 16 generates a reticle pattern to be displayed on the target position in an overlapping manner, and temporarily stores the generated reticle pattern in the reticle memory 17. The frame image that is the same as the frame image used for target detection is stored in the third frame memory 12 in parallel with the above-described target detection processing, and both memories stored in the reticle memory 17 and the third frame memory 12 are stored. After the recording is completed, the data is read out, superposed by the mixing circuit 18, converted into an analog signal by the D / A converter 19, and displayed on the image display device 20.

FIG. 14 is a diagram for explaining the screen display of the image display device 20, in which 26 is a screen, 27 is a target, and 28 is a reticle. As is clear from the above description, the target 27 of the previous frame is displayed and the reticle 28 is displayed in an overlapped manner on the detected target position, which helps the situation judge to visually judge.

[0006]

Since the conventional apparatus is constructed as described above, it usually takes about 10 seconds per frame for the target determination, and the target detailed image required for the determination can be displayed quickly. There was a difficulty that I could not do it. Further, as shown in FIG. 13, when the target is divided and stored over two frames, the target cannot be recognized and cannot be detected.

The present invention has been made in order to solve the above problems, and provides an image data analysis apparatus capable of detecting a target immediately after scanning a target without waiting for completion of one frame scanning. With the goal. It is another object of the present invention to provide an image data analysis apparatus which can detect a target more reliably by eliminating the risk of overlooking the target depending on the division position of the frame when the line scanning sensor scans the target.

In this embodiment, the line shift register for temporarily storing the video data for each operation of the line sensor instantaneous visual field, the means for sequentially executing the target detection processing in response to the output of the line shift register, and the result of the target detection processing are used for the satellite flight. An image data analysis apparatus using means for scrolling display in synchronization with scanning will be described. FIG. 1 is a diagram showing a part of the configuration of an embodiment of the present invention, and FIG. 2 is a diagram for explaining the screen display in this embodiment, in which 29 is a line shift register, 30 is a plurality of line image data, and 31 is a line image data. Scroll frame memory, 32 is a wide area image display device,
Reference numeral 33 is a target position information memory, and 34 is a scroll direction. 26 to 28 are the same as the reference numerals in FIG. 14 described above, and therefore description thereof will be omitted.

Next, the operation will be described. The video data 21 converted by the analog-digital converter 8 is input to the line shift register 29 line by line.
At that time, the oldest data among the data stored in the line shift register 29 is discarded. Although the number of storage lines in the line shift register 29 depends on the target size to be detected, normally 5 to 10 lines are sufficient. The image data is stored in units of pixels, which are the minimum unit points that form the screen. It can be considered that one line is composed of a plurality of pixels arranged horizontally. For example, one pixel is about 10
If the area of meters is covered, it is possible to detect a target object within a range of about 50 to 100 meters with the number of lines of 5 to 10 lines. Multiple line image data 3 output from the line shift register 29
0 is the target extraction image data 22 after the background such as clouds is removed by the target extraction filter 13 as in the conventional apparatus.

The target position coordinate data 15 stored in the target position information memory 33 can be used for later application of situation evaluation and the like. At the same time, the reticle image data 23 is generated by being input to the reticle memory 17 as in the conventional apparatus.

On the other hand, the oldest data in the scroll frame memory 31 is discarded for one line, and the latest video data 21 being scanned and acquired for one line is input to the line position. This will be described with reference to the drawings. FIG. 3 is a schematic diagram of a scroll frame memory. Normally, one frame memory is composed of about 500 to 1000 lines of data. After the data from the line scanning sensor is written in the nth line, the data in the (n + 1) th line is discarded at the first line, which is the oldest data, and is input to that line position. Similarly, the data of the next n + 2 line is discarded at the time and the data of the second line, which is the oldest data at that time, is discarded and is input to that line position.

FIG. 4 is a diagram for explaining frame scrolling in this embodiment. As described above, the scroll frame memory has a capacity for one frame only, and the latest data always overwrites the oldest data.

Then, the screen is displayed while scrolling in the scroll direction 34 shown in FIG. 2, and when the target 27 is detected, the reticle 28 is overlapped and displayed at that position, which can assist the judge's visual judgment.

By operating in this manner, in this image data analyzing apparatus, the latest frame image for each line scanning is obtained without waiting for the data constituting one frame to be alternately completed as in the conventional case. Therefore, the target can be detected in a short time. Also,
By reducing the step of the start position of the frame configuration, when the target is located at the boundary of the frame as in the conventional case, the target image data is not divided and the detection of the target is not missed. In this embodiment, the start position of the frame is set for each line, but 2 lines, 3 lines are set.
It may be an arbitrary step such as a line or 10 lines. The same applies to the output of the line shift register, that is, the input data to the target extraction filter.
