The object surface profile scanning instrument with laser is few in operation programs, high in equipment precision, exact in data and accurate in orientation.
Description
Technical field
The invention belongs to the actualizing technology field that visual field laser imaging is measured, be specifically related to a kind of laser profiling object surface scanner.
Background technology
Adopt general camera to carry out taking pictures imaging, normal conditions only can present the plane characteristic of object.By carrying out algorithm identification to color of object surface further, the 3D feature of a part of body surface can be reduced.But be limited by object color and lighting effect, computing gained 3D result often with actual conditions difference to some extent.
Adopt line laser as active probe source, coordinate a Daepori to lead to industrial camera and observe, body surface 3D feature is detected, effectively can reduce color of object surface, and the loss of significance that the environment such as lighting angle causes.
Its Cleaning Principle is, when line laser irradiates object perpendicular to body surface, industrial camera and Laser emission covering of the fan are taken at an angle.When body surface is smooth, the laser observed from camera angle will be a straight line segment at body surface; When body surface has projection or depression, laser line segment will be close to body surface, and from camera angle observation, line segment will be no longer flat level.Now according to the concrete data of laser profile, body surface surperficial 3D profile now can be calculated.
When coordinating servomotor technology, motor can be used to carry whole imaging system and to carry out precise motion, thus carrying out repeatedly data acquisition.According to the image mosaic technology of Digital Image Processing, the line data that imaging can be produced many are spliced, and form the body surface 3D profile of a width large format, thus carry out further calculation process.
