Embodiment Construction
[0028] Hereinafter, the present invention will be described in detail based on the drawings.
[0029] like figure 1 As shown, the present invention has designed a kind of single linear array satellite laser joint high-precision positioning processing method, and this method comprises the following steps:
[0030] Step (1) Use the single linear array satellite to swing back and forth along the orbit to obtain the stereoscopic image of the ground target at a set intersection angle, and obtain the coordinates of the image square with the same name through stereoscopic image registration, which are used to calculate the initial encryption point in step (2). object space coordinates.
[0031] Step (2) Obtain the initial outer orientation element corresponding to the single-line array image according to the initial parameters of the satellite, and calculate the initial object space coordinates of the encrypted point by using the initial outer orientation element and the single-line...
