Embodiment 1

[0133] Embodiment 1, for each suitcase to be matched, the electronic device may use the determined number of attributes as the similarity between the suitcase to be retrieved and the suitcase to be matched.

Embodiment 2

[0134] Embodiment 2, for each suitcase to be matched, the electronic device can calculate the ratio of the determined number to the total number of each attribute, and use the calculated ratio as the similarity between the suitcase to be retrieved and the suitcase to be matched. Spend.

[0135] In addition, it can be understood that since different attributes play different roles in matching the suitcase to be retrieved and the suitcase to be matched, each attribute can be used to match the suitcase to be retrieved and the suitcase to be matched. The importance of the role played by time, set the weight for each attribute.

[0136] In this way, in Embodiment 3, for each suitcase to be matched, the electronic device can calculate the weight sum of attributes with the same determined attribute value, and use the calculated attribute sum as the weight sum of the suitcase to be retrieved and the suitcase to be matched. similarity.

[0137] After executing the above step S103 and...

Abstract

The embodiment of the invention provides a luggage case retrieval method and device and electronic equipment. The method comprises the steps of obtaining a target image including image data of a to-be-retrieved luggage case and a to-be-retrieved video acquired by video acquisition equipment within a specified time range; carrying out luggage case detection on a video frame of the to-be-retrieved video to obtain a plurality of reference images including image data of a to-be-matched luggage case; calculating the similarity between the luggage case to be retrieved in the target image and the luggage case to be matched in each reference image; searching a target luggage case matched with the luggage case to be retrieved from the plurality of luggage cases to be matched according to the calculated similarity; and when the to-be-retrieved video is found, obtaining a shooting place and / or shooting time related to the target luggage case in the to-be-retrieved video. Compared with the prior art, by applying the scheme provided by the embodiment of the invention, the user can be quickly and efficiently assisted to find the lost luggage case.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a luggage retrieval method, device and electronic equipment. Background technique [0002] At present, many users choose an airplane as a means of transportation when traveling, and carry suitcases to store the clothes, nursing supplies, and working tools they need during the trip. [0003] For the suitcase carried by the user, due to the relevant regulations of the airline, the suitcase cannot exceed the preset weight. Therefore, the user needs to check the suitcase exceeding the preset weight. In this way, the user can wait at the baggage claim area after getting off the plane, and his suitcase will appear on the conveyor belt to pick up the suitcase. [0004] However, due to the need to check in a large number of suitcases in the airport every day, and there are a large number of users in the baggage claim area, each user needs to take away the suitcase in a short pe...
