Indoor image type plumb aligner calibration device

Abstract

The invention discloses an indoor image type plumb aligner calibration device. The device comprises an image processing system and a working base, a working platform is arranged on the working base, asupporting frame is arranged on the working base, a two-dimensional inclined platform for bearing a plumb aligner to be calibrated is fixed on the supporting frame, a supporting arm which is integrally formed with the base is arranged beside the working base, the supporting arm is fixedly connected with a collimator arranged in the vertical direction, an objective lens end of the collimator is downwards aligned with the position of an upward plumb line emitted by the plumb aligner to be calibrated, a first image shooting device is arranged on the collimator, the first image shooting device isused for shooting a reticle of the collimator and an image on the reticle, and the first image shooting device is in signal connection with the image processing system. Thus, the indoor image type plumb aligner calibration device is convenient to operate and use, high in calibration speed and high in accuracy and meets specification requirements.

Description

technical field [0001] The invention belongs to the technical field of instrument equipment detection and calibration, and in particular relates to an indoor image-type vertical collimator calibration device. Background technique [0002] The vertical collimator is based on the gravity line, and uses visible light or laser that coincides with the collimation axis to generate an upward and downward plumb line, which is used to measure the small horizontal deviation relative to the plumb line and to locate the plumb line, A measuring instrument for measuring the vertical profile of an object. Commonly used plummets include optical plummets, optical plummets with lasers, laser plummets and laser automatic plummets. It is widely used in the construction of high-rise buildings, high towers and chimneys, the installation of launch wells, frames and large-scale cylindrical mechanical equipment, elevator detection, horizontal displacement measurement of dams, engineering supervisio...

Problems solved by technology

[0003] JJF1081-2002 "Calibration Specifications for Plummeting Instruments" stipulates the technical requirements for parameters such as the coaxiality between the vertical axis and the collimating axis of the telescope, and the vertical alignment measurement deviation of one measurement round, and explains the calibration method of the technical indicators of the plummeting instrument. It is pointed out that the standard deviation of the one-round vertical measurement of the optical plummet and the optical plummet with laser is calibrated according to the indoor method, and it can be calibrated by a similar theodolite level calibration device, and the one-round vertical measurement of the laser plummet The standard deviation is calibrated according to the outdoor method, but there are the following problems when using the outdoor method to calibrate the laser plummet: (1) The calibration of the laser plummet is carried out on an outdoor site greater than 40 m, and air disturbance, air pollution, Environmental factors such as mechanical vibration have a great impact on the stability of the laser; (2) The outdoor working environment also puts forward higher requirements for the measurement personnel to accurately and stably arrange and erect the measurement equipment, and more than two (3) The calibration data needs to be manually estimated and read by the calibration personnel on the Cartesian coordinate board with a large division value

[0004] Chinese patent, the notification number is CN104949689A, the name is the laser plummet digital calibration method and device based on source imaging, the invention discloses a laser plummet digital calibration method and device based on source imaging, using the reticle as the projection Entity, by adding an imaging light source to image the reticle, so that the image of the reticle is projected onto the target at infinity, simulating the projection state at infinity, and comparing and calibrating with the debugging reference center on the target, according to The offset state at infinity adjusts the reticle. Compared with the device in the prior art that projects the debugging reference center at infinity onto the reticle, its calibration accuracy is higher, but it has not yet met the requirements of laser vertical alignment. Standard requirements for vertical collimation of the indoor one-test round of the collimator
