A method for enhancing a three dimensional image from frames of flash LIDAR data includes generating a first distance R_i from a first detector i to a first point on a surface S_i. After defining a map with a mesh Θ having cells k, a first array S(k), a second array M(k), and a third array D(k) are initialized. The first array corresponds to the surface, the second array corresponds to the elevation map, and the third array D(k) receives an output for the DEM. The surface is projected onto the mesh Θ, so that a second distance R_k from a second point on the mesh Θ to the detector can be found. From this, a height may be calculated, which permits the generation of a digital elevation map. Also, using sequential frames of flash LIDAR data, vehicle control is possible using an offset between successive frames.

The present invention is directed to enhancing the cleaning of surfaces by the contact application of a non-apertured nonwoven fabric having a three-dimensional image imparted therein.

The invention discloses a shell-imitated ceramic-based composite material. The shell-imitated ceramic-based composite material is prepared by an ice template method and a liquid-phase infiltration technology, and is characterized by comprising a layered structure, wherein ceramic layers and second phase layers are alternately overlapped to form a layered structure; each ceramic layer has surface projections and an interlayer bridging structure; and the ceramic layers and the second phase layers are bent in a wavy manner. Preparation of the wavy bent layered structure is realized by compression of a porous ceramic blank which has the straight layered structure, and meanwhile, the degree of bending of the ceramic layers can be controlled by adjustment of compression deformation of the blank. Along with increasing of amount of compression, the curvature of the bent ceramic layers in the blank is increased. Mechanical performance tests show that if the bending degree of the layered structure of the shell-imitated ceramic-based composite material is increased properly, the strength and fracture toughness of the composite material can be improved effectively.

The invention discloses a laser scanning three-dimensional point cloud tree automatic classifying method based on deep learning. The method can used to automatically classify an extracted single tree having a trunk and crown structure. A rotary side surface projection method is employed, and effective model training can be conducted even when tree data is less. Since a normalized pretreatment method is employed, the defect that the point cloud data densities of different distances (to a scanner) are non-uniform can be overcome. The influence of acquisition equipment on the result is minimal, and the result is more stable. Since deep learning is employed for model training, the accuracy for automatically classifying a plurality of trees is improved. A characteristic vector is used as a unit for calculation, and the calculation speed is fast. The method is more suitable for large-scale point cloud scene and has practical meanings and application values.
