Device and method for aiming of micro target pellet with diagnostic device

Abstract

The invention discloses a device and a method for aiming of a micro target pellet with a diagnosis device, belonging to the technical field of visual measurement of machines and aiming to solve the problem of contradiction between high precision and the manufacturing cost for aiming of the micro target pellet with the diagnosis device. The device comprises an optical imaging system, an image processing system which is used for signal transmission with the optical imaging system and a calibration board which is arranged at a target pellet and is provided with a plurality of straight lines, wherein the straight lines cross the centroid of the target pellet and are divided into sections with an known distance. The method comprises the following steps: determining the distance between the optical imaging system and the target pellet; calibrating internal and external parameters of the camera of the optical imaging system; accurately extracting the centroid of the image of the target pellet formed in the optical imaging system through subpixel extraction so as to obtain three-dimensional spatial coordinates of the target pellet, and judging whether a detection device accurately aims at the target pellet according to the three-dimensional spatial coordinates; and if the detection device does not aim at the target pellet with the set high accuracy, transmitting control parameters to a diagnosis platform for automatic posture regulation, thereby realizing the purpose that the diagnosis device accurately aims at the target pellet.

Description

technical field [0001] The invention relates to a detection device and method in the field of laser inertial confinement nuclear fusion, and mainly relates to the technical field of machine vision measurement. Background technique [0002] For the method of manually aiming the detection equipment at the target ball, there are disadvantages such as labor-intensive installation and debugging, and a low degree of automation. Therefore, the traditional manual aiming method is no longer suitable in the shooting range. In order to facilitate engineering, automation and reduce operating costs, it is very important to develop targeting technology that carries diagnostic equipment on a public diagnostic platform to achieve relevant engineering technical indicators. [0003] The main method for the diagnostic equipment to aim at the tiny target pellets adopts the detection method based on machine vision and the detection method based on optics. The detection method using machine vis...
