Title:
THREE-DIMENSIONAL MEASUREMENT SYSTEM AND MEASUREMENT METHOD FOR FEATURE POINT BASED ON PLANE OF FOUR-CAMERA SET ARRAY
Document Type and Number:
WIPO Patent Application WO/2017/124654
Kind Code:
A1
Abstract:
A three-dimensional measurement system and measurement method for a feature point based on a plane of a four-camera set array. The measurement method comprises: establishing a measurement system comprising at least one four-camera set arranged in a 2 x 2 array consisting of four digital cameras; performing a matching operation on feature points of an image acquired by the camera set; calculating, according to image coordinates of the matched feature points, spatial location coordinates of the respective feature points; and calculating, according to the spatial locations coordinates, other three-dimensional sizes of a measured object that need to be particularly measured to form three-dimensional point cloud data, establish a three-dimensional point cloud graphic, and carry out three-dimensional reconstruction. In the measurement system and the measurement method, point-by-point translation, superposition and comparison is directly performed on pixel points of a measured image in X-axis and Y-axis directions, and thus complete matching can be performed on all points of a measured object capable of being measured. The method of the present invention can greatly simplify a complex algorithm for binocular matching, and achieves a simple, quick, accurate and direct measurement of three-dimensional sizes of an object by using a multi-ocular camera system.
