Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] A global calibration method for a multi-station articulated arm-type measuring platform of the present invention comprises the following steps:

[0035] Set the starting position of the tracks on both sides, install the laser tracker and the three-dimensional target;

[0036] The target ball of the laser tracker is placed on the slider of the articulated arm measuring instrument on the side track, the slider starts to move from the starting position, and walks 10 meters along the track with a step length of 0.5 meters, and the laser tracker collects each slider The coordinates of the corresponding point after the stop, and the direction vector of the fitting track line;

[0037] At the starting position, the articulated arm measuring instrument and the laser tracker respectively measure the target ball coordinates of the laser tracker ...

Abstract

The invention relates to a global calibration method for a multi-station articulated arm type measuring platform, which comprises the following steps: setting the starting point of track movement on both sides, installing a laser tracker and a three-dimensional target; The block starts to move from the starting point of the movement, and walks 10 meters with a step length of 0.5 meters. The laser tracker collects the coordinates of the target ball after each slider stops, and fits the direction vector of the moving line; at the starting position, the joint arm measuring instrument and The laser tracker measures the coordinates of the target ball on the three-dimensional target respectively, and calculates the positional relationship between the joint arm measuring instrument and the laser tracker at the starting position; repeat the above process on the two side tracks; take the laser tracker coordinate system as the global coordinate system, Realize the unification of the coordinate system at any position on the 1st and 2nd side rails to the global coordinate system. The invention can realize the global calibration of the measurement mode in which the articulated arm measuring instrument can move freely in a large range, and provides a new way of global calibration of the multi-station articulated arm measuring platform.

Description

technical field [0001] The invention relates to a global calibration method of a multi-station articulated arm measuring platform, which can realize the global calibration of a measuring mode in which an articulated arm measuring instrument moves freely in a large range. Background technique [0002] The multi-station articulated arm measuring platform is a platform composed of double slide rails and double articulated arm measuring instruments that can measure geometric parameters in a large range. The working process is that the articulated arm measuring instruments measure workpieces at different positions on their respective guide rails. The surface point cloud is integrated with the measurement point cloud of different stations for overall data analysis. Therefore, it is required to establish the mutual positional relationship of the track joint arm measuring instruments on both sides at different measuring stations. A common practice is to divide the stations with sma...
