Abstract: In this paper, the idea of object-oriented fine modeling is proposed by using the technology of photo and point cloud fusion, and practices and explores a landscape sketch from three stages:data acquisition, data processing and model production. Through comparison, the advantages and disadvantages of data obtained by different types of sensors in the model results are analyzed. Finally use the point cloud and photo fusion modeling technology, the problem of rough geometry and poor texture of the real scene model is solved. It provides reference basic data for small-scale planning.

Key words: real scene model, refinement, point cloud fusion, geometry, texture
