Embodiment Construction

[0019] Briefly summarized, the present invention relates to a method and apparatus for generating a display of a 3D metrology surface. The method includes determining a 3D point cloud representation of the surface of the object in a point cloud coordinate space. An image of the object is acquired in the camera coordinate space and mapped to the 3D point cloud representation to generate a display of the surface of the object. If necessary, before the image is mapped onto the 3D point cloud representation, it is transformed from the camera coordinate space to the point cloud coordinate space.

[0020] The present teaching will be described in more detail below with reference to various exemplary embodiments thereof as shown in the accompanying drawings. Although the present teaching has been described in conjunction with various embodiments and examples, it is not intended to limit the present teaching to such embodiments. On the contrary, as those skilled in the art will recogni...

Abstract

Described are a method and apparatus for generating a display of a three-dimensional (“3D”) metrology surface. The method includes determining a 3D point cloud representation of a surface of an object in a point cloud coordinate space. An image of the object is acquired in a camera coordinate space and then transformed from the camera coordinate space to the point cloud coordinate space. The transformed image is mapped onto the 3D point cloud representation to generate a realistic display of the surface of the object. In one embodiment, a metrology camera used to acquire images for determination of the 3D point cloud is also used to acquire the image of the object so that the transformation between coordinate spaces is not performed. The display includes a grayscale or color shading for the pixels or surface elements in the representation.
