Introduction to 3D laser scanner
2019-06-01
A 3D laser scanner is an instrument that measures the size and shape of a workpiece by scanning technology. The laser scanner must use a rotating motor with good stability and precision. When the beam is hit (fired) by the motor. The multi-faceted prism is reflected to form a scanning beam. Since the multi-faceted prism is located on the front focal plane of the scanning lens and rotates uniformly to make the incident angle of the laser beam to the mirror continuously change, the reflection angle also changes continuously, and a parallel is formed by the action of the scanning lens. And continuous scan lines from top to bottom.
The 3D laser scanner system itself mainly includes a laser ranging system and a laser scanning system, as well as an integrated CCD and instrument internal control and correction system. In the instrument, through the rapid and orderly rotation of two synchronous mirrors, the narrow beam laser pulse emitted by the laser pulse emitter is sequentially swept through the measured area, and the measurement is transmitted from the surface of the object to be tested and returned to the instrument through the laser pulse. The elapsed time (or position difference) is used to calculate the distance, and the scanning control module controls and measures the angle of each pulsed laser, and finally calculates the three-dimensional coordinates of the laser spot on the object to be measured.
Hualang's latest HL-3DH-3M handheld 3D laser scanner system is a new portable scanning system developed by foreign countries. The scanning system adheres to the key leading technologies and front-end concepts of peripheral scanners in the field of portable scanning. With the goal of improving user productivity and saving measurement time, the scanning system is designed to meet customers' new application requirements, including dimensional verification and 3D digitization. 3D printing, rapid prototyping, reverse engineering design, vocational and technical education and training, technology research and development, ergonomics, industrial product reproduction, etc. It solves the problem of on-site scanning measurement of various large and complex products and successfully solves customer problems.
The above is some knowledge about laser scanners, I hope to help everyone.
