Embodiment Construction

[0062] The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0063] A method for expanding the observation range of a vertical line collimator and simplifying the algorithm. The vertical line collimator includes a base plate 1, a left vernier caliper and a right vernier caliper. Two aiming needles 3, four installation holes 5 are opened on the base plate 1, and the base plate 1 is fixed on the ground through the four installation holes 5. It is characterized in that a downstream cursor caliper is added on the lower edge of the base plate 1, and a downstream cursor caliper, a left vernier caliper and a right vernier caliper are used. The three measured values ​​of the vernier caliper expand the observation range of the vertical collimator and simplify the conversion of the observation data of the vertical collimator.

[0064] Further, the upper edge of the b

Abstract

The invention discloses a method for expanding the observation range of a vertical line collimator and simplifying an algorithm. The vertical line collimator comprises a bottom plate (1), a left vernier caliper (9) and a right vernier caliper (8). A left vernier caliper (9) is arranged on the left edge of the bottom plate (1). A right vernier caliper (8) is arranged on the right edge of the bottomplate (1). Two sighting needles (3) are arranged at the upper edge of the bottom plate (1). The method is characterized in that a lower vernier caliper (10) is additionally arranged at the lower edgeof the bottom plate (1), the observation range of the vertical line collimator is expanded by adopting three measurement values of the lower vernier caliper (10), a left vernier caliper (9) and a right vernier caliper (8), and the conversion of observation data of the vertical line collimator is simplified. The effective observation range of the vertical line collimator is expanded exponentially,so that the measurement space of the vertical line collimator is greatly improved, and the situation that the installation position of the instrument needs to be moved again when the position of a vertical line body exceeds the observation range of the instrument due to large deformation amplitude of a dam is greatly avoided.
