Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] Such as figure 1 As shown, it is a schematic flow chart of the uneven free station setting method based on the improved Bursa model of the present invention; an uneven free station method based on the improved Bursa model includes the following steps:

[0035] S1. Manually aim at at least 3 backsight points on both sides of the line at the initial setting site, and measure the coordinates of the backsight points;

[0036] S2. According to the backsight point coordinates measured in step S1, the improved Bursa model is used to calculate the set point coordinates and the route distance, and a...

Abstract

The invention discloses a non-leveling free station establishment method based on an improved Bursa model. The method comprises the steps that rearview points on a route are manually aimed at on an initial station establishment point, the improved Bursa model is adopted to calculate coordinates of a current station establishment point, odometer measurement information is utilized to calculate mileage from the current station establishment point to a next station establishment point, then three-dimensional coordinates of the current station establishment point are calculated, the distance, horizontal angle and vertical angle between the current station establishment point and each rearview point are calculated, and the steps are circulated till measurement of the route is completed. According to the method, after the rearview points are aimed at on the initial station establishment point, the three-dimensional coordinates of the current station establishment point and the distance, horizontal angle and vertical angle between the current station establishment point and each rearview point are calculated through the mileage from the current station establishment point, designed over-height, a longitudinal slope and other information by the adoption of the improved Bursa model, therefore, automatic measurement without the need for aiming at a measuring point on a subsequent stationestablishment point is realized, the workload of measurement is reduced, the working efficiency of measurement is improved, and the safety risk is lowered.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping, and specifically designs an uneven and free station setting method based on an improved Bursa model. Background technique [0002] Total station free station measurement has been widely used in various engineering fields and has played a very important role. After the introduction of total station free station measurement technology from Germany, it broke the traditional measurement mode and greatly improved the measurement efficiency. The total station free station measurement actually means that the total station can be erected in a certain place at will, and there is no need to center the total station, as long as the total station is leveled, it can be measured. This measurement method is to establish a corresponding independent coordinate system of the total station for each station. Different observation stations have different coordinate systems for the station, so the total...
