A measurement system and method based on binocular camera and structured light codec

Abstract

The invention discloses a measurement system and method based on a binocular camera and a structural optical codec. The measurement system comprises a control host, a projector and two cameras; the projector and the two cameras are all controlled by the control host; the projector is located between the two gray-scale cameras; the control host forms structural stripe light and transmits an image needing to be projected to the projector; the projector projects the structural stripe light onto a measured object serving as a projection object; the two gray-scale cameras are arranged side by sideto form a binocular gray-scale camera group, and the two gray-scale cameras respectively acquire left and right projection images; the acquired left and right projection images are transmitted to thecontrol host; the control host is further used for decoding the left and right projection images, matching stripes and calculating parallax so as to achieve the three-dimensional visual reconstructionof the measured object. The measurement system and method based on the binocular camera and the structural optical codec are implemented easily, and the imaging and measurement speed are fast.

Description

technical field [0001] The invention relates to a measurement system and method based on a binocular camera and structured light encoding and decoding. Background technique [0002] In the past two or three decades, with the rapid development of computer technology, the application of computer vision has transitioned from a fixed two-dimensional plane to an intuitive and flexible three-dimensional three-dimensional. In the industrial era of highly automated production, traditional two-dimensional measurement and three-dimensional contact measurement methods can no longer meet the needs of modern production. Therefore, modern industrial production puts forward an urgent demand for three-dimensional non-contact measurement. [0003] Optical 3D measurement technology is a kind of non-contact measurement, which has the advantages of high measurement accuracy, easy implementation, and the ability to measure objects with complex surfaces. Therefore, optical 3D measurement technolo...

However, the detection effect on objects with no texture or less texture on the surface of the measured object is not ideal

With the rapid development of industrial production automation, there is an increasing demand for the detection of objects with no or less texture on the surface of the object, but the current three-dimensional detection technology cannot fully meet its needs.
