Abstract: Based on the field data collection methods of terrestrial three-dimensional laser scanner，this paper analyzes the key points and key factors of scanning scheme design according to the structure characteristics and the surrounding environmenl of different scanning objects and the speclic appiucaluon of scanning results. Combined with two different types of scanning objects，it discusses the scanning scheme design and field data collection steps in detail，and focuses on the notes in field data collection.

Key words: three-dimensional laser scanning, scheme design, field, collection
