Abstract

The invention discloses an automatic rock core volume measuring device based on vision. The device comprises a measuring platform, and a six-degree-of-freedom manipulator, a tray, a three-dimensionalscanner and a high-precision rotating table which are arranged on the measuring platform, the three-dimensional scanner is supported on the measuring platform through a support, the support is fixedlyinstalled on the measuring platform, the high-precision rotating table is arranged under the three-dimensional scanner, and the high-precision rotating table and the tray are arranged under the six-degree-of-freedom manipulator. The invention also discloses two methods for automatically measuring the rock core volume by using the device. By combining an automatic control technology and image processing software, non-contact automatic measurement of the rock core volume is realized, the problems of large conventional manual measurement error, complex wax sealing and the like are solved, the accuracy is high, the speed is high, and the measurement precision, the measurement efficiency and the personnel safety in the measurement process are greatly improved.

Description

technical field [0001] The invention belongs to the field of machine vision measurement and at the same time belongs to the field of petroleum automatic equipment, and relates to a non-contact measurement technology of rock core volume, in particular to a vision-based automatic rock core volume measurement device and method. Background technique [0002] In the process of oil exploration and development, it is necessary to carry out drilling work according to the stratum level and depth of the geological design, put coring tools into the well, drill out rock samples, ore-bearing minerals taken out from solid mineral ore bodies or ore beds Rock or ore is called core. Core is the most intuitive and practical data to understand the characteristics of underground strata and ore-bearing. As an important data of conventional physical properties of petroleum exploration, core porosity is a parameter to measure the size of rock storage capacity, and it is one of the important param...
