[0041] Test method, three-point leveling method

[0042] Step 1: Use a high-precision electronic level to zero function at point a to observe the values ​​of three points a, b, and c: a: 0", b: -42", c: -24". (The following display values ​​are in units of second)

[0043]The second step: add 28" to the leveling nut at point b, and observe that a: -5", b: -14", c: -53".

[0044] The third step: add 40" to the leveling nut at point c, and observe that a: -17", b: -46", c: -13".

[0045] Step 4: Add 22" to the leveling nut at point b, and observe that a: -25", b: -24", c: -29".

[0046] Step 5: Add 3" to the leveling nut at point c, and observe that a: -26", b: -26", c: -26".

[0047] Step 6: Tighten the nut, adjust the fine file and observe to obtain a: -51", b: -55", c: -54".

[0048] Step 7: Reduce the leveling nut at point a by 2", and observe that a: -53", b: -55", c: -55". The numerical error of three points a, b and c is less than or equal to 3 to meet the requiremen...

[0061] Test method: three-point leveling method

[0062] experiment procedure:

[0063] Step 1: Use the vehicle-mounted high-precision electronic level to observe the values ​​of three points a, b and c: a: -298", b: 25", c: 144". (The following values ​​are displayed in seconds)

[0064] The second step: add 62" to the leveling nut at point a to reach the limit, and observe that a: -236", b: no observation, c: 107".

[0065] Step 3: The leveling nut at point c is reduced by 64", and the observation can be obtained a: no observation, b: 28", c: 43".

[0066] Step 4: Reduce the leveling nut at point b by 99", and observe that a: -124", b: -127", c: 120".

[0067] Step 5: The leveling nut at point c is reduced by 126", and observation can be obtained as a: -60", b: -70", c: -6".

[0068] Step 6: Reduce the leveling nut at point c by 31", and observe that a: -44", b: -56", c: -37".

[0069] Step 7: Add 9" to the leveling nut at point b, and observe that a: -49", b: -47", c: -...

Abstract

The patent of the present invention is mainly aimed at the rapid leveling method of large-caliber photoelectric theodolites. The high-precision electronic level is placed on the theodolite turntable, and the geometric principle of "two intersecting lines determines a surface" is considered and studied, and a geometric model is established to integrate high-precision The electronic level is fixed on the theodolite turntable, and the theodolite leveling legs are used for leveling by rotating the theodolite turntable, so that the horizontal inclination angles of the two mutually perpendicular coordinate axes of X and Y are equal, and the leveling work of the large-diameter photoelectric theodolite is completed. The scheme is simple and quick, and has high leveling accuracy and reliability.

Description

technical field [0001] The present invention is in the technical field of optical measurement, in particular to a method for quickly leveling a large-diameter photoelectric theodolite from field transition arrangement to various measurement processes. Background technique [0002] The large-caliber photoelectric theodolite is a photoelectric measurement and radiation characteristic measurement equipment developed according to the current situation of various aircraft measurement requirements. It is used to complete the measurement of new aircraft. The photoelectric theodolite can be flexibly deployed in China according to the working conditions. The trajectory of UAV and other moving and fixed "small, far, dark, fast" targets, while measuring the flight attitude of the initial and landing segments of the target, as well as the live mirror recording of the intersection measurement target, providing accurate data for real-time and post-event . At present, the more relevant re...
