Obstacle recognition method and device and robot

The invention provides an obstacle recognition method and device and a robot. The method comprises the steps that a first direct echo signal of a first radar, a second direct echo signal of a second radar and cross echo signals corresponding to the first radar and the second radar are acquired; the first radar and the second radar are used for detecting a target obstacle; determining a calculated distance between the first radar and the second radar based on the first direct echo signal, the second direct echo signal and the cross echo signal; and identifying the type of the target obstacle based on the actual distance between the first radar and the second radar and the calculated distance between the first radar and the second radar. According to the obstacle recognition method and device and the robot provided by the invention, the type of the target obstacle can be accurately recognized. 本发明提供一种障碍物识别方法、装置及机器人，所述方法包括：获取第一雷达的第一直接回波信号、第二雷达的第二直接回波信号，以及第一雷达和第二雷达对应的交叉回波信号；第一雷达和第二雷达用于探测目标障碍物；基于第一直接回波信号、第二直接回波信号以
