Range image projection

TīmeklisRange images and range grids. A range image is, in principle, a regular (i,j) grid of points with a depth at every pixel and a projection procedure for taking a point in 3D and mapping (projecting) it into to grid coordinates.In practice, the projection may … TīmeklisSlant Range to Ground Range Projection. Determine the ground range projection given a slant range of 2000 m and a grazing angle of 30 ∘. slantrng = 2000; grazang = 30; Compute the ground range projection. grndrng = slant2grndrange (slantrng,grazang) grndrng = 1.7321e+03.
