Embodiment 1

[0032] This embodiment provides a dynamic item search method in a home environment, establishes a household item-room spatial position probability model, proposes a household item search technique, and performs knowledge modeling on items through ontology technology.

[0033] Please refer to the attached figure 1 , the dynamic article search method includes the following steps:

[0034] S101, building a knowledge base.

[0035] Specifically, the specific implementation steps of the step 101 are:

[0036] S1011. Obtain corresponding knowledge from the open source knowledge base to establish a probability model of the household object-room spatial position, and store it in the knowledge base.

[0037] In this embodiment, the open-source knowledge base includes open-source datasets or search engines of family scenes, household items and rooms, and relationships between household items and household items, such as: LabelMe[ http: / / labelme.csail.mit.edu / Release3.0 ], Concept...

Embodiment 2

[0090] This embodiment provides a dynamic item search device in a home environment. Please refer to the attached figure 2 , the device includes an open source knowledge acquisition module 201, an article knowledge construction module 202, a knowledge base management module 203, a knowledge update module 204, a knowledge acquisition module 205, a task processing module 206, an environment discrimination module 207, a path planning module 208, and a knowledge reasoning module 209 , knowledge decision-making module 210 , autonomous navigation module 207 , item recognition module 208 and scene recognition module 209 .

[0091] The open source knowledge acquisition module 201 is used to acquire the relationship between household items and rooms from an open source knowledge base, establish a household item-room spatial position probability model, and store it in the knowledge base.

[0092] Specifically, the shown open source knowledge source refers to an open source data set or ...

Abstract

The invention discloses a dynamic article search method and device in a home environment, and the method comprises the following steps: receiving a service task, and extracting to-be-searched target dynamic article information; obtaining the probability of a to-be-searched target dynamic article in all rooms from a knowledge base, constructing a candidate room sequence, and determining an optimalsearch room; obtaining a static article most related to the target dynamic article to be searched in the optimal search room and other candidate rooms; acquiring a position relation between the most relevant static article and the target dynamic article to be searched from the knowledge base; searching and identifying the most relevant static article, and searching and identifying the target dynamic article according to the position relation between the most relevant static article and the to-be-searched target dynamic article. According to the invention, the service robot can quickly search the required dynamic article in the known family environment or the semi-unknown family environment, and can effectively infer and find the required dynamic article in the unknown family environment.

Description

technical field [0001] The present disclosure relates to the technical field of item search, in particular to a method and device for dynamic item search applied in a home environment. Background technique [0002] With the increasing aging of the population and people's pursuit of high-quality life services, the demand for home service robots continues to increase. At the same time, with the continuous development of robot technology, the intelligence of service robots is also increasing, which makes it possible for home service robots to provide daily tasks for people. An important requirement for service robots is the ability to perform routine operational tasks. [0003] If a service robot wants to complete daily operation tasks autonomously, the premise is that it can find the items to be operated in the dynamic unstructured home environment after receiving the operation task. However, such items (items that need to be operated) usually have the characteristics of sma...
