Abstract

The invention designs a micro-scale object surface reconstruction method based on line laser to SLM micro stereo vision and especially relates to combined usage of line laser and a stereo light microscope (SLM). A laser stripe image pair sequence is employed; and a micro-scale object surface is constructed again by processing the image pair sequence. The method comprises: a laser stripe image pair sequence is inputted; stripe center sub-pixel-level extraction is carried out; relative parameter calculation of a left image and a right image is carried out; longitudinal distortion correction at the stripe center is carried out; stripe center area segmentation is carried out; matching point parallax calculation is carried out; parallax stripe pose changing is carried out; a parallax curve surface is outputted; and then micro-scale object surface reconstruction is carried out. According to the invention, problems of complicated global image distortion correction and lots of wrong matching data in the stereo matching process during the traditional SLM vision reconstruction can be solved; and a process of lots of complex image fusion is also avoided. A novel micro-scale object surface reconstruction method is established. The provided reconstruction method has high novelty; and a precise method is provided for micro-scale object surface reconstruction.

Description

technical field [0001] The invention relates to a method for surface reconstruction of small-scale objects (with a size range of 0.1 mm to 0.5 mm) for stereoscopic vision of a stereo microscope (Stereo Light Microscope, referred to as SLM) with a line laser, in particular combining a line laser and SLM is used in combination to obtain a sequence of laser stripe images, estimate the parallax surface of small-scale objects by processing laser stripes in the image, and then reconstruct the surface of small-scale objects in the world coordinate system through visual model conversion, and establish a new and effective Surface reconstruction methods for small-scale objects. Background technique [0002] The structured light method is usually based on the principle of triangulation to reconstruct the three-dimensional surface of the object. The laser light emitted by the laser is reflected by the surface of the object and received by the camera to calculate the three-dimensional st...
