The invention discloses an obstacle recognition method and an automatic driving vehicle, and belongs to the technical field of automatic driving. The method comprises the steps that point cloud data collected by the autonomous vehicle is acquired, the point cloud data indicates obstacles around the autonomous vehicle, the point cloud data comprises a plurality of supporting columns, each supporting column comprises the feature of at least one data point, and the sizes of the supporting columns are the same; on the basis of each support column, encoding the feature of at least one data point included in the support column by using maximum response encoding and attention encoding to obtain a second encoding feature of the point cloud data, the second encoding feature including the first encoding feature of each support column; and performing obstacle identification on the second coding feature to obtain obstacle information of the obstacle. According to the scheme provided by the invention, when the obstacle is identified, the detail features and the overall features of the obstacle are comprehensively considered, the accuracy of identifying the obstacle is improved, and the driving safety of the automatic driving vehicle is further improved.
