In this paper we present experimental results on a novel Low-cost 3D scanning method using the three-dimensional laser scanning technology with Linear Laser beam and a Webcam (LLW) that apples for visual laser scanning mechanisms for the selection of points of interest in an arbitrary scene.Alternatively, 3D laser scanning is an established technology that can provide high resolution range images of object surfaces. We describe a method to extract these surfaces from scanned range images, register them in 3D mode, and combine them into a single surface representing the particular object from which volume, area, and thickness can be computed.The vast majority of the primary attended locations pointed to scene objects of potential interest for navigation and object detection tasks.Moreover, both sensor modalities complement each other, resulting in a greater variety of points of interest than one modality alone can provide. We validated (LLW) method by using it in mobile robots that generate an environment maps in rescue class robotic competition.Building 3D maps involves a number of issues. This paper addresses the issue of how to fuse the geometry data of the laser beam with webcam. The proposed algorithm allows texturing geometrical 3D scenes-models.
