The original shape of the Hall sides represents an isosceles acute triangle on whose vertex the Hall contact is formed. |
It forms an extremely acute triangle of claimed seabed. |
The largest angle of an obtuse triangle is more than 90 degrees, and the largest angle of an acute triangle is less than 90 degrees. |
This is illustrated as an acute triangle beside the two cameras in Figures 1 and 3, and its geometry is determined by the length of the camera unit and the parameters of image combination. |
