Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, a visually guided theodolite measurement method includes the following steps:

[0026] Step 1: Install a camera on the theodolite, and the front end of the camera is provided with an eyepiece; the camera adopts a high-precision camera with more than 8 million pixels; the theodolite adopts TM5100A.

[0027] Step 2: Calibrate the camera and theodolite combination, obtain the coordinates of the image mark center or the quasi-upright cube mirror cross cursor center in the image plane coordinate system through image processing, and calculate the theodolite rotation to the mark point center or cross according to the calibrated system model The horizontal angle and vertical angle required for the center position of the cursor to drive the theodolite motor servo system to achieve the purpose of visually guiding theodolite automatic measuremen...

Abstract

The invention discloses a theodolite measurement method based on vision guidance. The theodolite measurement method comprises the steps that 1, a camera is installed on a theodolite, and an eyepiece is arranged at the front end of the camera; and 2, the camera and the theodolite are combined for calibration, the coordinates of the image mark center or the collimating cubic mirror cross cursor center in the image plane coordinate system are obtained by image processing, the horizontal angles and vertical angles required for the theodolite to rotate to the center of the mark point or the cross cursor center are calculated according to a calibrated system model, so as to drive a theodolite motor servo system to realize the purpose of enabling the theodolite to perform automatic measurement through visual guidance. The measuring speed is improved, human errors are reduced, the working efficiency is greatly improved, and the measuring accuracy can meet the requirements of a spacecraft on precision measurement.

Description

technical field [0001] The invention relates to a vision-guided theodolite measurement method, which belongs to the technical field of automatic measurement. Background technique [0002] At present, the optical theodolite is a theodolite in which both the horizontal dial and the vertical dial are made of optical glass. It is an instrument used in surveying to measure horizon and vertical angles. It includes a telescope with reticles on the eyepiece for aiming. The telescope can be rotated along the horizontal axis and the vertical axis. These axes pass through two circular scales. It has a spirit level which, when supported on an adjustable tripod, is horizontal to indicate and display results. [0003] In the measurement of large-scale spatial coordinates, in order to adapt to the complexity of the industrial field measurement environment and the diversity of measurement requirements, different measurement systems are combined. Theodolite measurement system is favored...
