Disclosed are remote spatial calibration apparatuses and spatial calibration methods. A first plurality of line-generating lasers is arranged for generating a first set of substantially parallel lines in a first orientation. A second plurality of line-generating lasers is arranged for generating a second set of substantially parallel lines in a second orientation. Both sets of lines are directed to project on an object and the second orientation is substantially perpendicular to the first orientation such that the lines form a matrix of lines. An imaging device is configured for obtaining an image of the object and the matrix of lines formed on the object. The spatial calibration apparatuses may be included in a housing comprising a projection face, an imaging device cavity formed in the projection face, and a plurality of laser cavities formed in the projection face.
