A self-parallel method and device for industrial ct scanning motion

Abstract

The invention discloses an industrial CT motion autoparallel method. The method comprises the steps of acquiring the position of the starting point of scanning, determining a ranging reference generatrix nearest to the starting point of scanning on a scanning copy, and acquiring the first distance between the starting point of scanning and the ranging reference generatrix; acquiring an analog scanning path with the starting point of scanning as the starting point, selecting the position of a reference point on a projection line obtained after the analog scanning path is projected onto a reference plane, and acquiring the second distance between the reference point and the ranging reference generatrix; determining the path from the starting point of scanning to a target terminal point according to the second distance, the first distance, the position of starting point of scanning and the position of the reference point. The method is applicable to the condition that the scanning copy is not parallel to a clamp body as well as the condition that the axis of the scanning copy is not parallel to a standard scanning path, the scanning path can be made parallel to the actual rotating axis of the scanning copy through autoparallel adjustment, and scanning accuracy and convenience are guaranteed. The invention further discloses an industrial CT motion autoparallel device.

Description

technical field [0001] The invention relates to the technical field of industrial scanning, more specifically, to a self-parallel method and device for industrial CT scanning motion. Background technique [0002] Industrial CT is an imaging technology widely used in various fields, which is developed on the basis of radiation detection. [0003] The existing industrial CT equipment geometric position relationship adjustment technology is mostly manual adjustment, and most of the industrial CT equipment’s radiation sources and detectors have only translation and radial movement axes, or only translation and lifting movement axes, making the geometric position relationship adjustment The method is cumbersome and not flexible enough. After the equipment is transported to the testing site, it takes more time to adjust the geometric positional relationship of the equipment so that the equipment meets the basic coordinate setting of the testing. The existing industrial CT equipm...
