Laser beam fast automatic positioning tracking measurement method and device

Abstract

The invention discloses a laser beam fast automatic positioning measurement device and a method thereof in laser tracking measurement process. According to the method, a laser tracking measurement device is used as a supporting platform, a right angle ball rod component is rapidly set up to form a rectangular coordinate system, three standard balls installed with wireless distance measurement devices are connected through two rod pieces to form the right angle ball rod component, the sphere center distance is a fixed value, a signal is sent to the wireless distance measurement devices through a self-positioning remote control at the position of a measured target, the distance is calculated through an information processing platform, and thereby the spatial three-dimensional coordinates of the target position can be determined; the spatial three-dimensional coordinates are sent to the laser tracking measurement device to guide the laser beam to roughly point to the target position; the laser beam is captured by a photoelectric detection part which is installed on the self-positioning remote control and automatically shot to the center of a reflecting portion to complete the navigation and automatic positioning of the laser beam; and the precision measurement for the target position can be completed by combining the laser tracking measurement device.

Description

[0001] Technical field [0002] The invention belongs to the technical field of mechanical manufacturing precision measurement, and relates to a laser beam rapid automatic positioning and tracking measurement method and a device thereof, and is particularly suitable for rapid positioning after the laser beam is cut off in the laser tracking measurement technology. Background technique [0003] In recent years, the laser tracking measuring instrument is a high-precision large-size measuring instrument in industrial measurement systems. It has the characteristics of high precision, high efficiency, real-time tracking measurement, quick installation, easy operation, etc. It can track the space moving target and measure the space three-dimensional coordinates of the target in real time. It is suitable for any large-size measurement occasions and is used in the manufacturing and installation of large equipment The process is widely used. The basic working principle of the laser tracki...

Problems solved by technology

[0005] The above method solves the problem of light interruption to a certain extent and makes the measurement process continuous, but the fundamental problem has not been solved. When the measurement range is large, such as the measurement of straightness and cylindricity of large flue ducts, the measurement of missile launchers in the defense industry The measurement of verticality, etc., needs to climb up and down. If the distance between two adjacent measurement points is several meters, or even tens of meters, it is inevitable or even necessary to cut off the light; Be careful, it will cause damage to the reflector and cause economic loss
