Abstract: A method for searching a path by using a 3D reconstructed map includes: receiving 3D point-cloud map information and 3D material map information; clustering the 3D point-cloud map information with a clustering algorithm to obtain clustering information, and identifying material attributes of objects in the 3D point-cloud map information with a material neural network model to obtain material attribute information; fusing the those map information based on their coordinate information, thereby outputting fused map information; identifying obstacle areas and non-obstacle areas in the fused map information based on an obstacle neural network model, the clustering information, and the material attribute information; and generating 3D path information according to the non-obstacle areas. Since the 3D path information is generated based on those map information, the obstacle areas and flight spaces are effectively determined to generate an accurate flight path.

Abstract: The present invention discloses a simple house structure that includes a framework, a floorslab, a wallboard and a shingle, and the framework includes a pedestal coupled to each first vertical rod, a first corner pillar, a first edge pillar and a first center connector disposed at different positions of each first vertical rod, and a second vertical rod connected to each first corner pillar, edge pillar and center connector, and each second vertical rod includes a second corner pillar, a second edge pillar, and a second center connector disposed at different positions of each second vertical rod, and a transversal rod installed between each connectors, and a diagonal rod installed between each transversal rod and first and second vertical rods, such that the house structure can have a better strength and achieve the effects of quick installation and dismantling.
