Quick positioning and tracking method and device for specific face in crowd on the basis of mobile terminal

Abstract

The invention discloses a quick positioning and tracking method for a specific face in a crowd on the basis of a mobile terminal. The method comprises the following steps that: receiving searched object information input by a user; collecting environment data; and after a situation that the environment data contains the searched object is identified according to the searched object information, notifying the user that the searched object is detected; and after a confirmation message sent from the user is received, sending a notification message to the searched object. The method provided by the embodiment of the invention is based on the intelligent terminal, the notification message is sent to the object after the searched object is identified to prompt the user that the searched object is found and surrounding environment needs to be paid attention, and a situation that a search result loses efficacy due to the quick movement of the searched object can be avoided. Therefore, by use of the method, existing equipment is fully utilized, meanwhile, the function of the searched object can be performed, the subjective initiative of the searched object is improved, operation is simple, and person searching efficiency is high. The invention also discloses a quick positioning and tracking method for the specific face in the crowd, and also can realize the above technical effects.

Description

technical field [0001] The present invention relates to the field of face recognition, and more specifically, to a method and device for quickly locating and tracking a specific face in a crowd based on a terminal device. Background technique [0002] In daily life, we often need to pick up people in densely populated public places such as airports or stations. We are limited by environmental interference, personal recognition ability, and attention. Surveillance video in public places, even if the face recognition program is installed, the surveillance cameras in some public places are damaged, there are blind spots in the monitoring range, and even some public places do not have a perfect surveillance system, resulting in low efficiency in finding people, so use The monitoring system in public places has certain limitations in finding people. [0003] In the existing technology, users can use face recognition equipment to find people in public places, but they must first ...

Problems solved by technology

[0002] In daily life, we often need to pick up people in densely populated public places such as airports or stations. We are limited by environmental interference, personal recognition ability, and attention. Surveillance video in public places, even if the face recognition program is installed, the surveillance cameras in some public places are damaged, there are blind spots in the monitoring range, and even some public places do not have a perfect surveillance system, resulting in low efficiency in finding people, so use The monitoring system in public places has certain limitations in finding people

[0003] In the existing technology, users can use face recognition equipment to find people in public places, but they must first purchase such hardware equipment

However, this type of device does not use the attention of the person being found, and ignores the role of the person being found in the process of finding someone. Therefore, in a crowded public place, this type of device requires the user to approach quickly after discovering the person being found, otherwise they will be caught. The person you are looking for will disappear in the crowd, and the result of this search will be invalid

In addition, in general, it is only occasionally to find people in public places, so buying a device for this is obviously a waste of resources and the cost is high
