4 3 Feature-Point Three-dimensional Measuring System of Planar Array of Four-camera Group and Measuring Method

摘要

The present invention relates to a three-dimensional measurement system and method for measuring feature points of a four-camera group planar array and belongs to the technical field of optical electronic measurement technology products and methods. And a measurement system constructed by four camera groups of at least one group constituting a 2x2 array group with four digital cameras. A matching operation is performed on the feature points of the image collected by the camera group, Calculating spatial position coordinates of each feature point based on the phase coordinates, calculating other three-dimensional sizes to be specifically measured of the measured object based on the spatial position coordinates to form cloud data of the three-dimensional points, Construct a figure and perform three-dimensional stereoscopic reproduction. The present invention can perfectly match all measurable points of a measured object after parallel movement, superimposition, and comparison of the measured image directly in the X-axis and Y-axis directions according to one pixel point, Can be simplified to the maximum extent, and an effect of directly measuring the three-dimensional size of an object can be achieved simply, quickly, and accurately using a multi-camera.
