The invention provides an intelligent wheelchair bed control method based on an ORBSLAM2 algorithm, and the method comprises the following specific steps: 1, building a hospital map: a first part of a tracking module is mainly divided into feature extraction and matching, pose prediction or repositioning, local map tracking and key frame judgment; the second part is to construct a local map. And the third part is closed-loop detection, and a global map is generated. According to the method, firstly, feature points of a hospital are accurately extracted through an ORBSLAM2 algorithm, and a hospital model is continuously established and improved through the feature points; after a task is accepted, a route is planned, the old or the disabled losing action ability are carried to go to a designated place and on the way, obstacles are found and avoided through a camera, a laser radar, an infrared sensor and an ultrasonic sensor carried by the old or the disabled, and the real-time obstacle avoidance ...
