Embodiment Construction
[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0049] Such as figure 1 As shown, the specific implementation steps of a method for obtaining a three-dimensional attitude of a carrier based on the horizon and polarized light in the present invention are as follows:
[0050] Step (1) Use the forward-looking camera of the carrier to obtain the horizon information, and calculate the line equation L of the horizon in the image coordinate system, and use the line equation L, the height H of the carrier from the ground, and the camera parameters to estimate the roll angle γ and pitch angle of the carrier θ;
[0051] Step (2) Use the apparent polarization camera on the carrier to obtain a set of sky polarization images, and calculate the sky polarization degree information p and polarization azimuth information And extract the polarization neutral point in the sky polarization image;
