A method for processing information, comprising: identifying at least one obstacle from a point cloud, the point cloud being collected by a lidar provided on a vehicle during a traveling process of the vehicle; for each obstacle of the at least one obstacle, determining an appearance rate of the obstacle within a life cycle corresponding to the obstacle, the life cycle corresponding to the obstacle referring to a process from the obstacle being detected until the obstacle disappearing; determining a confidence degree of each grid region of at least one grid region based on appearance rates of obstacles in the at least one obstacle, the at least one grid region being obtained by dividing a collection area of the lidar; determining a target grid region from the at least one grid region based on the confidence degree, and determining whether an obstacle detected in the target grid region is an obstacle detected for a first time, wherein the determining a target grid region from the at least one grid region based on the confidence degree comprises: selecting a grid region with a confidence degree less than a preset threshold from the at least one grid region, for use as the target grid region; and in response to determining the obstacle detected in the target grid region being the obstacle detected for the first time, filtering out a point cloud corresponding to the obstacle detected in the target grid region for the first time, wherein the filtering out a point cloud corresponding to the obstacle refers to filtering out the point cloud corresponding to the obstacle, without reporting the point cloud corresponding to the obstacle, and without sending control information to the vehicle based on the point cloud of the obstacle. identifying at least one obstacle from a point cloud, the point cloud being collected by a lidar provided on a vehicle during a traveling process of the vehicle; for each obstacle of the at least one obstacle, determining an appearance rate of the obstacle within a life cycle corresponding to the obstacle, the life cycle corresponding to the obstacle referring to a process from the obstacle being detected until the obstacle disappearing; determining a confidence degree of each grid region of at least one grid region based on appearance rates of obstacles in the at least one obstacle, the at least one grid region being obtained by dividing a collection area of the lidar; determining a target grid region from the at least one grid region based on the confidence degree, and determining whether an obstacle detected in the target grid region is an obstacle detected for a first time, wherein the determining a target grid region from the at least one grid region based on the confidence degree comprises: selecting a grid region with a confidence degree less than a preset threshold from the at least one grid region, for use as the target grid region; and in response to determining the obstacle detected in the target grid region being the obstacle detected for the first time, filtering out a point cloud corresponding to the obstacle detected in the target grid region for the first time, wherein the filtering out a point cloud corresponding to the obstacle refers to filtering out the point cloud corresponding to the obstacle, without reporting the point cloud corresponding to the obstacle, and without sending control information to the vehicle based on the point cloud of the obstacle.
