DEVICE AND METHOD FOR RETRIEVING MOBILE OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for retrieving a person by which action history of a specific person is efficiently retrieved by suppressing useless retrieval while securing parallelism from a group of video images photographed with a plurality of cameras. SOLUTION: The device for retrieving the person has a retrieval range restriction part 104 which restricts a retrieval range of time or a place and a peripheral node inquiry part 105 which executes retrieval to peripheral nodes 12 dotted on a distributed network using the restricted retrieval range, wherein the retrieval range restriction part 104 repeatedly execute the retrieval by re-restricting the retrieval range based on retrieval results of the peripheral node inquiry part 105 to attain retrieval of a person by suppressing the useless retrieval while securing the parallelism.
