Not only has important theoretical significance, but also has significant practical value, a very broad application prospects. Three-dimensional information acquisition and processing techniques have important applications in large areas with the development and application of modern information science and technology came into being. Defense technology and industrial applications, medical imaging industry, its needs are becoming increasingly urgent. Three-dimensional information acquisition and processing technology has a collection of the latest achievements of a number of disciplines such as machinery, electronics and information science, optics and computer is an integrated emerging technologies. Three-dimensional digitization of information will be converted into three-dimensional information in the real world to the digital signal so that the computer can deal directly with these three-dimensional digital signal processing to restore or rebuild the digital model of the object. Here will introduce the function of electronic pointer of  laser pointer .
More recently, with the development of computers, imaging equipment, Electrical and optical integration technology, the three-dimensional information for the devices become more intelligent, measured from exposure to non-contact measurement, faster and faster, getting higher and higher accuracy, access to information the range is also growing. People to quickly and easily, with high accuracy the wide scene, object measurement, to obtain three-dimensional data. It is hoped that a breakthrough in this area more, faced with the problem is how to deal with these huge three-dimensional data. 1.2 3D coordinates of methods for measurement of space object data acquisition refers to the use of a measurement method or measuring equipment to measure the physical surface of a number of point three-dimensional space coordinates. The function of remote control of  laser pointer  will be described in details.laser pointer  is used to indicate and highlight the content
The largest measuring method of classification, data acquisition can be divided into destructive measurement and non-destructive measurement of the two forms, a branch of which non-destructive measurement method, a detailed breakdown see Figure 1-1. The following non-destructive measurement method used more often several measurement methods: contact measurement refers to the use of contact measuring device outer surface of the physical measurements, such as coordinate measuring machine CMM (Coordinate Measurement Machine Coordinate Machine) as a precision measurements in the industrial field has been widely used, it is the use of sensors to control the fast-moving of the measuring head in the workbench, to quickly record the next path point coordinates.
