Problems solved by technology

[0003] The current hospital beds are mainly divided into two types, one is ordinary beds, which require medical staff to push and transport patients, occupying the limited medical resources of the hospital; the other is electric beds, most of which are based on multi-functional auxiliary monitoring. However, obstacle avoidance and autonomous path planning cannot be performed during the movement of the hospital bed, which makes it inconvenient to move the electric hospital bed when it is used in the hospital, and the work efficiency is not high

Embodiment 1

[0039] figure 1 It is a flow chart of the automatic obstacle avoidance and path planning method of the automatic cruising electric hospital bed involved in this embodiment. Please refer to the attached figure 1 , the autonomous obstacle avoidance and path planning method of the automatic cruising electric hospital bed comprises the following steps:

[0040] S101. Obtain image information of corridors on each floor of the hospital and image information of departments and wards, and determine corridor boundary information and location information of departments and wards.

[0041] In this embodiment, the camera scans the corridor walls of each floor in the hospital and each department and ward in advance, determines the corridor boundary information and the location information of each department and ward, and records the corridor boundary information and each department and ward information on each floor of the hospital. Department ward location information.

Embodiment 2

[0069] This embodiment provides an autonomous obstacle avoidance and path planning system for an automatic cruising electric hospital bed, the system includes:

[0070] The information acquisition module is used to obtain the corridor image information of each floor in the hospital and the image information of each department and ward, and determine the corridor boundary information and the location information of each department and ward;

[0071] The path planning module is used to establish a two-dimensional hospital model by using the grid method based on the corridor boundary information of each floor of the hospital and the location information of each department and ward, and perform path planning for the walking route of the electric hospital bed;

[0072] The obstacle avoidance module is used to control the electric hospital bed to walk according to the planned path, collect the obstacle information in front of the electric hospital bed, and judge whether an obstacle i...

Embodiment 3

[0098] This embodiment provides a computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0099] Obtain the corridor image information of each floor in the hospital and the image information of each department and ward, and determine the corridor boundary information and the location information of each department and ward;

[0100] Based on the corridor boundary information of each floor of the hospital and the location information of each department and ward, a two-dimensional hospital model is established by using the grid method, and the path planning of the walking route of the electric hospital bed is carried out;

[0101] Control the electric hospital bed to walk according to the planned path, collect the obstacle information in front of the electric hospital bed, judge whether an obstacle is detected, if an obstacle is detected, adjust the direction of travel of the el...

Abstract

The invention discloses an autonomous obstacle avoidance and path planning method and system for an automatic cruise electric sickbed. The working efficiency of the electric sickbed is improved. The method comprises the following steps: acquiring gallery image information of each floor in a hospital and ward image information of each department, and determining gallery boundary information and ward position information of each department; based on the gallery boundary information of each floor of the hospital and the ward position information of each department, establishing a two-dimensionalhospital model by using a grid method, and performing path planning on the walking path of the electric sickbed; controlling the electric sickbed to walk according to the planned path, collecting obstacle information in front of the electric sickbed, judging whether an obstacle is detected or not, adjusting the advancing direction of the electric sickbed to avoid the obstacle if the obstacle is detected, otherwise, keeping the path unchanged, and continuing to advance until a destination is reached.

Description

technical field [0001] The invention relates to the technical field of obstacle avoidance and path planning, in particular to an autonomous obstacle avoidance and path planning method and system for an automatic cruising electric hospital bed. Background technique [0002] As a new type of medical bed, the electric hospital bed has gradually replaced the traditional medical bed because of its convenient operation and multiple functions, and has been widely used in hospitals. It is of great practical significance to study an intelligent electric hospital bed that can not only travel but also provide services. and social value. [0003] The current hospital beds are mainly divided into two types, one is ordinary beds, and the transportation of patients requires medical staff to push and transport them, occupying the limited medical resources of the hospital; the other is electric beds, most of which are based on multi-functional auxiliary monitoring. However, obstacle avoidan...
