3D scanning 3D measurement 3D scanning, as the name implies, is to measure the measured object in all directions and determine the 3D coordinate measurement data of the measured object. The measuring principle is divided into four aspects: ranging, angular displacement, scanning and orientation. The instruments developed according to the principle of 3D technology include three kinds of measuring instruments: photographic (structured light) 3D scanner, laser 3D scanner and CMM. Three dimensional measurement Three dimensional scanning can be defined as "a kind of detector that can move in three directions, and can move on three mutually perpendicular rails. This detector transmits signals in contact or non-contact ways. The three axis displacement measurement system passes the data
The principle of structured light scanner optical 3D scanning system is to continuously project the grating onto the object surface, and the camera synchronously collects the image, then calculates the image, and uses the phase stable polar line to realize the 3D space coordinates (X, Y, Z) on the two images, thus realizing the measurement of the 3D contour of the object surface. The principle of laser scanner is also called time method because the scanning method takes time as the calculation basis. It is a very accurate, fast and simple instrument, and can be installed on the production line to form an instrument for inspection while producing. The basic structure of the laser scanner consists of a laser light source and a scanner, a light receiving sensor (
The development of intelligent robots promotes the sensor industry, and sensors will also be the "catalyst" for the development of the intelligent robot industry. Recently, the robot industry, as a new big industry, has become one of the focuses of the development of the manufacturing industry. As the main component of robot work, sensors play an important role in the development of the robot industry. With the development of robot industry, it also brings new vitality to related industries, such as machine vision, sensors, etc. The external sensors of intelligent robots mainly include mechanical touch, proximity, sensing, sliding and thermal sensors. Sensor destruction is the basic premise of intelligent robot work, only
