Problems solved by technology

Currently, there are many applications of structured light for single-camera and single-projector, but there are still few applications for multi-camera and multi-projector, most of which are still in the research stage, and there are few related experimental platforms for multi-camera and multi-projector on the market , the current structured light experimental platforms on the market are mainly supported by tripods. Some companies have developed small special experimental platforms for their own products, but the structured light experimental platforms for general purpose, large multi-camera and multi-projection have not yet been seen.

Abstract

The invention discloses a structured light experiment platform of multi-camera and multi-projector, which comprises an experimental platform, a camera adjustable mount, a projector adjustable mount, and a rotating platform. The array of the X-axis direction and the Y-axis direction of the upper end plate of the experimental platform is uniformly arranged with a plurality of tapping screw holes. The camera adjustable mount and the projection adjustable mount are mounted in the tapping screw holes by bolts, and the position of the camera adjustable mount and the projection adjustable mount on the upper end plate is adjustable. The top platform of the rotating platform can be rotated 360 degrees. The invention can be used for three-dimensional reconstruction of single-camera and single-projection, and can also be used for three-dimensional reconstruction of multi-camera and multi-projection, and can be used for researching reconstruction effects of different camera-projectors at differentpositions for comparison test. The camera adjustable mount, projector adjustable mount and rotating platform are equipped with servo motors, so that important parameters such as running speed and rotation angle can be precisely controlled by the program.

Description

Technical field[0001]The invention relates to the technical field of three-dimensional reconstruction experiment platforms, in particular to a structured light experiment platform with multiple cameras and multiple projectors.Background technique[0002]With the continuous improvement of people's requirements for imaging, the traditional two-dimensional imaging technology can no longer meet the demand. Now, more and more technologies based on three-dimensional images are emerging, enriching people's lives and promoting the development of science and technology. In order to obtain real three-dimensional images, we usually have to perceive the depth of scenes or objects. Structured light technology is a widely used depth perception technology. Three-dimensional imaging based on structured light is actually the measurement and reproduction of three-dimensional parameters. It is necessary to actively project structured light onto the measured object, and determine the size of the measured...
