Description

  The present invention relates to an automatic object shape recognition system and a writing system for a contactless identification tag.

Automating the transportation procedures for goods, luggage, etc. is important in reducing labor costs and time spent on handling procedures.
In response to this problem, Ioi System Co., Ltd. has proposed a loading / unloading support system that uses automatic recognition of products using barcodes and a position detection device that detects the position of a forklift (see Non-Patent Document 1 below). . The outline of this technique will be described below.
FIG. 7 is a diagram for explaining this conventional warehouse support system.
First, a barcode 102 issued from a computer (not shown) is attached to the product 101. The barcode 102 is printed with an identification code of the product 101.
The warehousing worker 104 carries a wireless terminal 103. The wireless terminal 103 includes means for wirelessly communicating with a computer (not shown), a barcode scanner (not shown), and a display for displaying information (not shown). (Omitted).
The position detection device 105 constantly detects the position of the forklift 106 and notifies the computer and the wireless terminal 103.
When the warehousing worker 104 scans the barcode 102 affixed to the product with the barcode scanner of the wireless terminal 103, the wireless terminal 103 automatically recognizes the identification code, and the warehousing position of the product corresponding to the identification code by wireless communication. The information is inquired of the computer via wireless communication.
When the computer receives the inquiry, it retrieves the storage location of the product 101 and transmits it to the wireless terminal 103.
The wireless terminal 103 displays the storage position of the product 101 and the current location of the forklift 106. The warehousing worker 104 moves the forklift 106 to the position displayed on the wireless terminal 103 and enters the product 101. After completing the warehousing of the product 101, the warehousing worker 104 notifies the computer that the warehousing is completed by the wireless terminal 103. The computer that has received the report compares the position of the forklift 106 when the warehousing is completed with the position where the product 101 is to be stored, and if it is correct, notifies the wireless terminal 103 of “confirmation of warehousing”.
With this system, the warehousing worker 104 can confirm the warehousing destination of the product 101 and the current position of the forklift 106, so that work efficiency can be improved. Further, since it is confirmed that the position of the forklift 106 is equal to the position where the product 101 should be received every time the warehousing operation is performed, it is possible to prevent the product 101 from entering the wrong place. The administrator can easily grasp the warehousing status of the product 101 by making an inquiry to the computer.

An object shape automatic recognition system. Non having transmitting and receiving means for transmitting a response signal containing information stored before Symbol storage means receives the storage means and question signal to store the information of the identification information and the object of the object is an identification target Means for transmitting the interrogation signal to the contact identification tag, receiving and reading the response signal returned from the non-contact identification tag, and means for transmitting the information of the object to the non-contact identification tag and writing to the storage means A wireless terminal having
A first photographing device for photographing the object from a first direction and outputting first image information;
A second photographing device for photographing the object from a second direction and outputting second image information;
Using the difference in contrast between the background and the object in the first and second image information, the contour of the object is extracted to generate shape information of the object, and the first and second image information utilizing the area in which the object occupies generates size information of the object, the shape and to output to the radio terminal as the information for the size information the object, the before and SL identification shape and size information in writing system to the contactless identification tag comprising a data processing means for storing in a database the door,
The non-contact identification tag is coated with a fluorescent paint on the surface, and affixed to the object,
The data processing means further detects a relative position of the non-contact identification tag taken as a light emitting point by the fluorescent paint in the first or second image information with respect to a contour of the object, and the non-contact in the object. Affixing position information of the contact identification tag is generated, and the affixing position information is output to the wireless terminal as the object information, and the affixing position information is stored in a database.
A system for writing on a non-contact identification tag. 4. The system for writing into a non-contact identification tag according to claim 3 , wherein the identification information stored as a database by the data processing means is read from the non-contact identification tag by the wireless terminal. . The system for writing to a non-contact identification tag according to claim 3, wherein the non-contact identification tag acquires drive power of an internal circuit by a signal received from the wireless terminal. The identification information inputted by a predetermined input means and the unique information about the object are written by the writing means together with the shape and size information generated by the data processing means and the pasting position information of the non-contact identification tag. 4. The non-contact identification tag writing system according to claim 3 , wherein the non-contact identification tag is written in the storage means.
