Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recognition device,
Especially, it is related to explanation of animals in aquariums and zoos.

[0002]

2. Description of the Related Art Conventionally, when a fish or animal is viewed and observed at an aquarium or zoo, many unknown fish or animals are bred. Therefore, the organizer posts photographs of these fish and animals for explanation and also describes the explanation. Many of the children, such as infants and children, come to visit aquariums and zoos, and such people cannot read the letters. Also, the organizer wants to give as much detailed explanation as possible to the fish / animals, but if too many explanations are given in text, it will be complicated and difficult to read. Therefore, there was a problem that I could not fully explain because I ended up writing the minimum explanation.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to allow a visitor to image a living thing such as an aquarium or a zoo with a camera and receive an explanation of the corresponding living thing. .

[0004]

In order to solve the above-mentioned problems, according to the present invention, a camera for photographing fish, animals, etc., a drive unit for driving the camera horizontally and vertically, and an operation for operating the camera, etc. Section, an A / D conversion section for converting a video signal of the camera into a digital signal, a memory section for storing the converted data, and an image storage section for storing a plurality of reference images of fish, animals, etc. A guide storage unit that stores the description of the fish / animal stored in the image storage unit and audio data to be explained, and the fish / animal that approximates by comparing the data in the memory unit with the data in the image storage unit An identification part,
The image data of the fish / animal identified by the identification unit is read out from the image storage unit, and the description of the corresponding fish / animal is read out from the guide storage unit and displayed, and the speaker, and the control for controlling each unit. And an image recognizing device including a unit.

[0005]

According to the above construction, the camera is turned to the fish to be instructed by operating the operation section. The video signal of the photographed fish is converted into a digital signal by the A / D conversion unit and stored in the memory unit. The image of the reference fish is stored in the image storage unit, and the identification unit compares the reference data with the data of the memory unit to select a fish to be approximated. The control unit reads out the specified fish data from the image storage unit and displays the data on the display unit, and also displays the description of the corresponding fish stored in the guide storage unit. Further, the explanation contents of the corresponding fish stored in the guide storage unit are output from the speaker.

[0006]

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, reference numeral 1 denotes a camera, which photographs fish, animals and the like. A driving unit 2 drives the camera 1 horizontally and vertically to change the camera angle. An operation unit 3 operates the camera 1 and the drive unit 2. Reference numeral 4 is an A / D converter, which converts a video signal from the camera 1 into a digital signal. A memory unit 5 stores the converted data. Reference numeral 6 denotes an image storage unit, which has a plurality of reference fish / animals and has a reference size and
Store images taken from multiple angles. An identification unit 7 compares the data in the memory unit 5 with the data in the image storage unit 6 and selects a fish / animal to be approximated. 8 is a guide storage unit,
The explanation sentence and the explanation voice of the reference fish / animal stored in the image storage unit 6 are stored. Reference numeral 9 denotes a display unit which reads out and displays the data of the fish / animal identified by the identification unit 7 from the image storage unit 6 and also displays the explanatory note stored in the guide storage unit 8. Reference numeral 10 is a speaker, which outputs the explanation contents stored in the guide storage unit 8 by voice. Reference numeral 11 denotes a binarization circuit unit which converts the data in the memory unit 5 into bright and dark data.
Reference numeral 12 is a contour extraction unit that extracts a contour from the binarized data. A control unit 13 controls each of the above units.

In the above-mentioned structure, for example, if a fish unknown to oneself enters the aquarium and swims, what is the name of this fish, where is the place of production, etc., the operating portion 3 is operated to drive the driving portion 2. To rotate the camera 1 horizontally and vertically,
Take a picture of the target fish. The image captured by the camera 1 is output as a video signal, converted into a digital signal by the A / D converter 4,
It is stored in the memory unit 5. Then, the binarization circuit unit 11 binarizes the data in the memory unit 6 (A in FIG. 2) to set the background to a “0” value and the fish to a “1” value as shown in FIG. 2B. Next, the photographed fish is set to a reference size for comparison and identification with a reference fish stored in the image storage unit 6 (for example, stored in a rectangular image area of 100 × 70 dots). Therefore, the area and contour of B in FIG. 2 containing many “1” values are replaced with a rectangle having a 100 × 70 dot ratio (C in FIG. 2), and the size of the replaced rectangle is a reference value (100 × 70 dots). If it is different from, the data is enlarged or reduced to the reference value. If the fish was photographed in any of the up, down, and diagonal positions, first replace the fish with a rectangle according to the above procedure, and set it to the standard size, then
Next, rotate the rectangle by the angle of the fish and correct it to a recognizable position.

Therefore, the identification unit 7 compares the data processed above with the data in the image storage unit 9 and selects a fish to be approximated. The control unit 13 displays the fish data selected by the identification unit 7 from the image storage unit 6 on the calling display unit 9 and also displays the description of the fish stored in the guide storage unit 8,
In addition, the speaker 10 outputs the description content of the fish stored in the guide storage unit 8. As another method for comparing the fish with the reference fish, the contour extracting unit 12 extracts the contour by the image extracting method disclosed in JP-A-5-312483, and the identifying unit 7 stores this data and the image storage unit 9 in the image storing unit 9. Select a fish that has a standard size and that has a high degree of coincidence compared with the binary image data taken from multiple directions such as front, side, and diagonal. If the degree of coincidence is low, the data can be enlarged or reduced to continue the comparison, and if they do not coincide, the reference fish can be changed to the second and third fish to compare and the fish with a high degree of coincidence can be selected.

[0009]

As described above, according to the present invention, even an infant or a child who enters an aquarium or the like can operate the camera to photograph a desired fish, and the explanation of the name of the fish, the place of origin, the habitation of the fish, etc. is displayed on the screen. Also, since it is output from the speaker, there is an advantage that detailed explanation can be received even if the characters cannot be read.
