Measurement system and measurement method

Abstract

The invention discloses a measurement system and a measurement method. The measurement system comprises a measurement module comprising a camera and a laser displacement sensor; the laser displacementsensor is used for measuring the distance from a measurement reference point of the laser displacement sensor to a measurement point on a first assembly surface in the laser emitting direction of thelaser displacement sensor; a calculating device is used for calculating a rotation angle that a second part needs to rotate around an x axis, a rotation angle that the second part rotates around a yaxis and the translation amount that the second part translates in the z-axis direction so that the first assembly surface and a second assembly surface can be overlapped; the camera is used for shooting a feature group picture of a feature group; and the calculating device is further used for calculating the translation amount of the second part in the x-axis direction and the translation amountof the second part in the y-axis direction in order to make a midpoint coincide with the reference point, and a rotation angle that the feature group needs to rotate around a z axis to move a preset position after the midpoint coincides with the reference point. The measurement system is high in measurement precision.

Description

technical field [0001] This article relates to robotics, in particular to a measuring system and measuring method. Background technique [0002] At present, the final assembly of high-precision equipment with large load and large size is completed manually. The traditional manual-based assembly mode has problems such as backward assembly equipment, poor accuracy consistency, and uncontrollable risks. This assembly mode is only suitable for single-piece, small-batch, small-scale, and simple-structure spacecraft assembly, but it is far from meeting the requirements of modern large-scale High-precision equipment requires high precision, high efficiency, and flexibility for final assembly. Robot autonomous assembly provides an effective solution for improving the assembly accuracy, efficiency and flexibility of high-precision equipment, which can greatly improve the comprehensive quality of equipment and the production level of manufacturing enterprises. With the rapid develop...

Problems solved by technology

However, the current robot autonomous assembly system usually adopts three construction methods: building in the end coordinate system, building in the installation base coordinate system and building in the global coordinate system. These three coordinate system construction methods will have deformations that affect accuracy, The narrow space leads to problems such as incomplete collection of information and the inability to use the diverse needs of assembly tasks
