JPS6234480A - Monitor device for moving material body - Google Patents

Abstract

PURPOSE:To easily compare a material body to be monitored with a picture to be a reference by displaying the picture to be the reference and a picture of the material body to be monitored on different areas in parallel at the same time on the screen of the same monitor. CONSTITUTION:A material body 11 is fed by a feeder 14 and a rotating shaft of the feeder 14 is connected to a rotating position sensor 15. A video signal of a picture being a normal reference of the material body is written in a prescribed area of a memory 19 and recorded. By a signal of a control part 17, a luminous device 18 emits light, the video signal of the material body 11 is obtained by a television camera 12 and the video signal is written in the prescribed area of the memory 19. The two video signals are read and displayed on different parts for each picture of a monitor 13, the two pictures are compared, and the moving material body is monitored as a still picture.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a moving object monitoring device that continuously monitors a moving object. The present invention relates to a moving object monitoring device suitable for monitoring.゛ [Prior art and its problems] In order to monitor a moving object while it is still moving, a method has been adopted in which the object is displayed as a still image and checked on a monitor. This system digitizes the video signals of moving objects captured at predetermined intervals and writes them into memory.
The signal is continuously retrieved from memory and displayed on a monitor as a still image. The AD-converted video signals are sequentially written into the memory. This allows the image of a moving object to be displayed as a still image that changes at regular intervals.

FIG. 2 shows a method of monitoring using still images as described above. In FIG. 2, the object 21 moves from right to left and the imaging bag [2
2, an image is obtained and displayed on the monitor 23 as a still image. After the object 21 has moved a predetermined distance, the portion of the object 210 song is similarly displayed on the monitor 23. This process is repeated to check the books 21 one after another.

However, even if a moving object is captured as a still image, it is updated sequentially, making it difficult to discover defects in a short period of time.Also, in order to compare with normal images, both the monitor image and the pond image are used. There is a problem that it must be done.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a moving object monitoring device that can easily compare a monitored object with a reference image.

Another object of the present invention is to obtain a moving object monitoring device that does not require any special equipment and can be used as a conventional device.

[Means for solving problems]

The present invention achieves the above object by simultaneously displaying a reference image and an image of an object to be monitored on different areas of the screen of the same monitor in parallel.

That is, in a moving object monitoring device using an image processing device that obtains a still image of a moving object by emitting light from a light source, the device includes a storage device that simultaneously stores a plurality of images, and still images recorded in advance in the storage device are provided. Still images, which are sequentially recorded and updated in the storage device, are simultaneously displayed on different areas of the screen of the long-display device.

This makes it easy to detect differences simply by comparing two images on a single monitor.

[Implementation sequence of the invention]

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing an implementation sequence of the present invention.

The object 11 is being moved from right to left by the feed station 14. The rotating shaft of the feeding device [14] is connected to a rotational position sensor 15. The position control unit 16 generates a pulse signal at a specified position in response to the signal from the position control unit 15.
7. The control unit 17 controls the operation of the device, and controls the operation of the light emitter 18 and the like. The memory 19 records video signals from the television camera 12, and writing and the like are controlled by a memory controller 20. The video signal recorded in the memory 19 is displayed on the monitor 16.

Here, a plurality of image areas are allocated to the memory 19, and the video signal of the reference image is recorded in a predetermined area, and the still image of the moving object is sequentially displayed in the area of the pond. These images are displayed on the monitor 13 simultaneously.

Next, the operation of the moving object monitoring device of the present invention will be explained.

The video signal of the image that serves as a normal reference of the object is stored in the memory 19.
Write and record it in a designated area. This video signal is repeatedly read out and displayed on the monitor 13 together with individual video signals that are updated while being recorded at predetermined intervals.

The light emitter 18 emits light in response to a signal from the control section 17 . At this time, a video signal of the object 11 is obtained by the television camera 5/12, and this video signal is AD converted and written into a predetermined area of the memory 19 as a digital signal. Of course, this area must be different from the area in which the video signal of the reference image is written.

Both of the two video signals written in the memory 19 are read out and displayed on different parts of the monitor 15, respectively. If they are lined up, they will be displayed vertically on the screen as shown in Figure 1.

Six video signals are sequentially input into the area of the memory 19 in which images of moving objects are recorded at regular intervals.

As a result, the images displayed on the monitor 13 also change sequentially, but the reference image does not change. The two images are then compared on each screen, and the moving object is monitored as a still image.

Note that by dividing the recording area of the memory 19 into smaller sections for writing and controlling reading, it is also possible to display and compare two sets of images at the same time. Further, recording and changing of the reference image may be performed in the same manner as in a normal recording method.

[Effects of the Invention] According to the present invention, since a moving object can be displayed simultaneously with a reference image, checking can be easily and accurately performed.

It also has the advantage that it can be realized only by controlling memory loading and padding, and does not require any special equipment.
