Baggage search method and a baggage information management system

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.

• 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 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.

A baggage information management system for managing a target image of a search target baggage by associating with a target ID stored in a radio tag attached to the search target baggage, the baggage information management system comprising

• a camera to photograph the search target baggage being conveyed by a conveyance line,
• a tag reader installed in a position capable of communicating with the radio tag attached to the search target baggage being conveyed by the conveyance line and that acquires the target ID stored in the radio tag,
• a memory unit memorizing a search target information including the target image and the target ID stored in the radio tag attached to the search target baggage,
• a control unit storing the target image of the search target baggage photographed by the camera and the target ID read by the tag reader at a timing when the search target baggage is photographed by the camera as the search target information in association with each other in the memory unit,
• a wireless communication unit wirelessly transmitting the search target information stored in the memory unit to an operator terminal used by an operator searching for the search target baggage as the search target information, wherein the operator terminal further includes:
• a tag communication unit that communicates with the radio tag and reads the search target information stored in the radio tag,
• an orientation estimation unit that estimates an orientation of the radio tag with respect to the operator terminal based on a response radio signal from the radio tag received from the tag communication unit, and
• a display unit that displays the orientation estimated by the orientation estimation unit,
• wherein
• the display unit displays a no existing fact that the search target image is not included in the pictured image on the display unit;
• and
• the orientation estimation unit displays the estimated orientation estimated by the orientation estimation unit on the display unit after the no existing fact is displayed on the display unit.
