Problems solved by technology

[0007] The present invention aims at the target recognition problem of the existing ward patrol service robot, and provides a ward patrol service robot system and its target search method, which completes the active control of the target of interest in the ward environment through the active control of the robot and the vision system. Search, so as to realize robot ward inspection, use multiple modes for target representation, and use multi-mode representation of targets for target positioning and search

Embodiment Construction

[0075] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0076] figure 1 Among them, after the mobile robot enters the ward, it first conducts patient information verification: it moves to the head of the bed using a pre-planned path, and an RFID tag is attached to the head of the bed. Prior knowledge, etc., through the RFID reader carried by the robot to read the RFID tag on the head of the bed to achieve fast and accurate patient information verification. If the RFID authentication matches the record in the database, the next inspection task will be carried out, otherwise, the robot will call the police and wait for the nurse to confirm, and at the same time, proceed to the next patient inspection. Then the robot performs rough positioning of the target through the carried RFID, and then performs fine positioning through the body vision; at the same time, the robot relies on StarGazer for positioning, uses...

Abstract

The invention relates to a ward visit service robot system and a target searching method thereof. In the method, a way for searching a target by combining the Bayesian theory with multi-mode target expression and priori knowledge is put forward, and a mechanism for actively searching a target in the complex environment of a ward by a method for combining active vision, characteristic extraction and characteristic verification is provided. By using body vision of a robot and RFID (Radio Frequency Identification Device) information, active robot ward visit is realized. A robot positioning system is obtained by a StarGazer system through Kalman filtering; a robot control system expresses an expression target through multiple modes of a target by using the Bayesian theory and controls the robot in combination with the priori knowledge; a target position is obtained while the pose of the robot is controlled, so that the target is positioned by a method for using active vision and combination characteristic; and a camera is controlled by a partition logic method, and a shot picture is sent to a server side for displaying and storing.

Description

technical field [0001] The invention relates to a ward inspection service robot system and a target search method thereof, belonging to the field of nursing robots. Background technique [0002] The current research on nursing robots has made great progress, and it is mainly used to assist nurses to complete some related nursing activities, such as low-intelligence activities such as drug delivery. Ward inspection is an important link in nursing work, but there are a lot of problems at this stage. Therefore, it is a topic of great practical significance to solve the contradiction between nurse nursing quality, labor load, and excessive mental pressure by developing nursing inspection robots. However, there is little research on this topic in China. The tasks to be completed by the robot ward inspection mainly include: patient information verification, patient status monitoring, wound site inspection, monitoring and treatment equipment status photography, image transmission,...
