Spatial data acquisition by laser scanning for robot or SHM task

This paper presents through of the principle of laser triangulation a technique to acquisition data from an environment. The prototype can discover obstacles or objects in a unknown environment. Using a light source (laser) and very simple but efficient scanning unit is possible determinate distances and angles of any point on object in environment based in data acquisition by these elements. The most important parameters are: accuracy, functioning speed, range of action, and power requirements; the main characteristics is based in simplicity, versatility and economical accessibility. Fully automatic navigation and monitoring system is able to implement this prototype.
