Abstract

A baggage search method including following processes: an information acquisition process for acquiring a search target information including a search target image of a search target baggage and a target ID stored in a radio tag attached to the search target baggage, an image collation process for collating a pictured area that contains at least a part of a baggage group containing the search target baggage selected by an operator with the search target image included in the search target information by a processing unit, a displaying process for displaying the pictured area highlighting a baggage area in which the target baggage is included and an ID collation process which the processing unit collates an ID of the radio tag read by the tag communication unit of an operator terminal operated by the operator with the target ID included in the search target information.

First claim

The invention claimed is:

1 . A baggage search method in which an operator searches for a search target baggage with a radio tag by using an operator terminal equipped with a search information acquisition unit, a tag communication unit, a camera, a display unit and a processing unit, the method including following processes:
an information acquisition process in which the search information acquisition unit acquires a search target information including a search target image which is a photographed image of the search target baggage and a target ID stored in the radio tag attached to the search target baggage; an image collation process in which the processing unit collates a pictured area including at least a part of a search target baggage group which includes the search target baggage photographed by the camera of the operator terminal operated by the operator with the search target image included in the search target information; a displaying process for displaying the pictured area highlighting a baggage area in which the search target baggage is included when the processing unit determines that the pictured area includes the search target image; and an ID collation process in which the processing unit collates an ID of the radio tag read by the tag communication unit of the operator terminal operated by the operator with the target ID include in the search target information, wherein the operator terminal further includes an orientation estimation unit that estimates an estimated orientation of the radio tag with respect to the operator terminal based on a response radio signal from the radio tag received by the tag communication unit, wherein
in the displaying process the processing unit displays a no existing fact that the processing unit determines that the search target image is not included in the pictured image on the display unit; and
the baggage search method further includes:
an orientation estimating process for displaying the estimated orientation estimated by the orientation estimation unit on the display unit, wherein the estimated orientation is displayed after the no existing fact is displayed on the display unit.

2 . The baggage search method of claimed in claim 1 , wherein the image collation process is re-executed after the orientation estimating process is executed.

3 . The baggage search method of claim 1 , wherein
the ID collation process is a first ID collation process, and further including:
a second ID collation process in which the processing unit determines whether an ID of the radio tag acquired by the tag communication unit of the operator terminal operated by the operator after the orientation estimating process matches with the target ID of the search target information.

4 . The baggage search method of claim 3 , further including:
a prior-orientation estimation process for estimating an orientation of the radio tag by using the orientation estimation unit, wherein the prior-orientation estimation process is executed after the information acquisition process and before the image collation process.

5 . The baggage search method of claim 1 further including:
a prior-orientation estimation process for estimating an orientation of the radio tag by using the orientation estimation unit, wherein
the prior-orientation estimation process is executed after the information acquisition process and before the image collation process.

6 . The baggage search method of claim 5 , wherein
the image collation process is performed based on a comparison of a R value, a G value and a B value of the search target image with the R value, the G value and the B value of the pictured area.

7 . The baggage search method of claim 1 , wherein
the image collation process is performed based on a comparison of a R value, a G value and a B value of the search target image with the R value, the G value and the B value of the pictured area.

8 . The baggage search method of claim 1 , wherein
the search target information further includes a hue, a brightness and a saturation of at least the part of the search target baggage, the operator terminal further includes a colorimeter that measures the hue, the brightness and the saturation, and the processing unit collates the hue, the brightness and the saturation measured by the colorimeter with the hue, the brightness and the saturation of the search target information.

9 . A baggage search method in which an operator searches for a search target baggage with a radio tag by using an operator terminal equipped with a search information acquisition unit, a tag communication unit, a camera, a display unit and a processing unit, the method including following processes:
an information acquisition process in which the search information acquisition unit acquires a search target information including a search target image which is a photographed image of the search target baggage and a target ID stored in the radio tag attached to the search target baggage; an image collation process in which the processing unit collates a pictured area including at least a part of a search target baggage group which includes the search target baggage photographed by the camera of the operator terminal operated by the operator with the search target image included in the search target information; a displaying process for displaying the pictured area highlighting a baggage area in which the search target baggage is included when the processing unit determines that the pictured area includes the search target image; and an ID collation process in which the processing unit collates an ID of the radio tag read by the tag communication unit of the operator terminal operated by the operator with the target ID include in the search target information, wherein the image collation process is performed based on a comparison of a R value, a G value and a B value of the search target image with the R value, the G value and the B value of the pictured area.

10 . The baggage search method of claim 9 , wherein
the search target information further includes a hue, a brightness and a saturation of at least a part of the search target baggage, the operator terminal further includes a colorimeter that measures the hue, the brightness and the saturation, and the processing unit collates the hue, the brightness and the saturation measured by the colorimeter with the hue, the brightness and the saturation of the search target information.

11 . A baggage search method in which an operator searches for a search target baggage with a radio tag by using an operator terminal equipped with a search information acquisition unit, a tag communication unit, a camera, a display unit and a processing unit, the method including following processes:
an information acquisition process in which the search information acquisition unit acquires a search target information including a search target image which is a photographed image of the search target baggage and a target ID stored in the radio tag attached to the search target baggage; an image collation process in which the processing unit collates a pictured area including at least a part of a search target baggage group which includes the search target baggage photographed by the camera of the operator terminal operated by the operator with the search target image included in the search target information; a displaying process for displaying the pictured area highlighting a baggage area in which the search target baggage is included when the processing unit determines that the pictured area includes the search target image; and an ID collation process in which the processing unit collates a
