A feature point matching method of a planar array of a four-camera group and a measuring method based on the feature point matching method of the planar array of the four-camera group relate to the field of optical electronic measurement. The matching method comprises determining unique matching point groups on four imaging planes corresponding to the same viewed point. For each unique matching point group, three-dimensional space coordinates of the viewed point can be calculated according to image coordinates of the matching point group and parameters of the camera system itself. Under any illumination conditions, as long as the acquired image is clear enough, for any viewed object imaged on an image of a planar array of a four-camera group and having certain image features, using completely identical matching method and measuring method can realize three-dimensional measurement of the viewed object.

A system for measuring object points on a three-dimensional object using a planar array of a multi-camera group, and a measuring method, are provided. The system is useful in the field of optical measuring technologies. The method includes establishing a measuring system of at least one four-camera group wherein digital cameras form a 2&#xd7;2 array; matching an image object point acquired by the camera group; upon matched object point image coordinates, calculating coordinates of spatial locations of respective object points; upon coordinates of the spatial locations, calculating other three-dimensional dimensions of the measured object to be specially measured to form three-dimensional point clouds and establish a three-dimensional point clouds graph for performing three-dimensional stereoscopic reproduction. Here, full matching is performed for all measured points of the measured object by directly translating, superimposing, and comparing, point-by-point, the pixel points of measured images in X and Y-axes directions. In this way a three-dimensional object may be reproduced.
