Immersive man-machine environment interactive positioning measurement method

Abstract

The invention discloses an immersive man-machine environment interactive positioning measurement method, comprising the following steps: (1) building a portable measuring helmet; (2) measuring the spatial position of a to-be-measured target point; (3) determining the spatial pose of the measuring helmet; (4) unifying the coordinates to a global coordinate system; and (5) displaying measurement information. The method of the invention has good portability, and can help free the hands of measurement personnel. The method ensures excellent coordination with other operations especially in industrial large-scale assembly and detection, enhances the flexibility of measurement, and facilitates smooth conduction of measurement tasks in a complex environment. Moreover, measurement personnel can acquire measurement information in real time, and the man-machine interaction experience is good. Measurement personnel can immerse themselves in measurement objects and measurement scenes. The efficiency of measurement in an industrial field can be improved.

Description

technical field [0001] The invention relates to the field of precision measurement and positioning of industrial large-scale environments, in particular to an integrated human-machine environment interactive positioning measurement method. Background technique [0002] Most of the existing industrial large-scale measurement methods for assembly and inspection are carried out by manual operation of special measuring instruments and equipment. The measurement equipment is generally separated from the front-end measurement personnel, such as laser trackers, indoor GPS, etc. These methods are relatively portable. Poor and unable to liberate the hands of the measurement personnel, especially in the interior space of the equipment with limited volume, the flexibility of the above measurement method is greatly limited. In addition, the front-end surveyors are often unable to obtain the measurement information of the current location in real time, the interaction between the surveyo...

Problems solved by technology

[0002] Most of the existing industrial large-scale measurement methods for assembly and inspection are carried out by manual operation of special measuring instruments and equipment. The measurement equipment is generally separated from the front-end measurement personnel, such as laser trackers, indoor GPS, etc. These methods are relatively portable. Poor and unable to liberate the hands of the measurement personnel, especially in the interior space of the equipment with limited volume, the flexibility of the above measurement method is greatly limited

In addition, the front-end surveyors are often unable to obtain the measurement information of the current location in real time, the interaction between the surveyors and the measuring equipment is poor, and the analysis and comparison between the measured data and the theoretical value is difficult to be carried out directly on site. These factors make it difficult for the surveyors to truly integrate into the In the measurement scene, it greatly restricts the measurement efficiency of the industrial site and the development of work tasks

[0003] Taking the laser tracker as an example, in the process of using the laser tracker to perform assembly or inspection tasks, the front-end measurement personnel generally only need to place the reflective target ball at the position to be measured. On the one hand, the measurement personnel need to hold the target ball. Poor, which reduces the work efficiency; on the other hand, the surveyor is far away from the laser tracker and computer, and cannot intuitively obtain measurement information, and cannot grasp the progress of the current measurement task in real time

The above factors make it difficult for the laser tracker to carry out measurement tasks in a complex industrial environment, especially in a limited space. It is even more difficult for measurement personnel to integrate into the measurement scene, which restricts the improvement of work efficiency and product quality.
