Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0026] The present invention is a light-weight and dynamic configuration method for photoelectric sensors of a large-scale R-LATs measurement network. figure 2 , including the following steps:

[0027] 1. System preprocessing:

[0028] The master control software is the terminal of the R-LAT measurement system, which receives photoelectric sensor data and performs top-level tasks such as coordinate calculation. The master control software needs to prepare the following data before running the R-LATs system:

[0029] a) measure the external parameters of the rotating laser theodolite of all R-LATs networks in the space, the external parameters include the spatial position matrix (R, T) and the number Trans_id;

[0030] b) The R-LATs measurement network is divided into multiple local networ...

Abstract

The invention provides a lightweight dynamic configuration method for a photoelectric sensor of a large-scale R-LATs measurement network. The method comprises the following steps: dividing a R-LATs measurement network into local network units; calculating the coordinates of the photoelectric sensor in real time; and then a local network unit in which the R-LATs measurement network is located. Thus, the rotational speed information of a rotating laser theodolite in the local network unit is sent to the photoelectric sensor for real-time configuration, thereby ensuring that an optical plane recognition algorithm of a photoelectric sensor surface only needs the optical plane traceability of the currently-updated rotating laser theodolite. Thus, the lightweight calculation task of the photoelectric sensor is ensured; the real-time response and sampling frequency of the system are improved; and the expansion ability of the photoelectric sensor is not influenced.

Description

technical field [0001] The invention belongs to the field of large-scale space measurement, relates to large-scale rotating laser theodolite measurement network (R-LATs) networking measurement, in particular to a photoelectric sensor lightweight dynamic configuration method for large-scale R-LATs measurement network. Background technique [0002] Rotating laser theodolite network (R-LATs) is an important method for large-scale space measurement. Through reasonable station layout, the measurement space expansion of any size can be realized, and it has an unlimited number of parallel measurement capabilities. Its measurement accuracy can be maintained at ±0.2mm, and it is widely used in aerospace and military fields such as aircraft manufacturing, shipbuilding, and large antenna manufacturing. [0003] In the R-LATs work, each rotating laser theodolite emits two fan-shaped plane lights with an included angle, and rotates at a constant speed at a specified speed. At the same ti...
