specific Embodiment approach 1

[0027] Specific implementation mode one: see figure 1 Describe this embodiment, a machine vision-based automatic tracking and monitoring system described in this embodiment, which includes a first micro-vision system 1, a second micro-vision system 2, a third micro-vision system 3, an air tube Fine-tuning auxiliary clamping piece 4, reflector 5, negative pressure adsorption head 6, and pellet micro-adjustment platform 7;

[0028] The structure of the first micro vision system 1, the second micro vision system 2 and the third micro vision system 3 is exactly the same, the negative pressure adsorption head 6 is placed on the target pellet micro-adjustment platform 7, the negative pressure adsorption head 6 is used to adsorb the target pellet 8,

[0029] The center of reflecting mirror 5 is provided with through hole, and gas-filled tube 9 is positioned at the top of reflecting mirror 5, and passes through the through hole of reflecting mirror 5, and reflecting mirror 5 forms 45...

specific Embodiment approach 2

[0037] Specific embodiment two: the difference between this embodiment and the automatic tracking and monitoring system based on machine vision described in specific embodiment one is that the diameter of the mirror 5 is 20 mm, and the diameter of the through hole on the mirror 5 is 3mm.

[0038] In this embodiment, since the reflector is hollow and at an angle of 45 degrees to the horizontal, in order to ensure that the inflatable tube can pass through smoothly while reducing the loss of light energy, it is necessary to analyze and calculate the influence of the existence of the through hole on the imaging of the reflector. In the known microscope The size of the mirror and the size of the opening of the mirror can be calculated from the numerical aperture and the distance of the mirror relative to the target.

specific Embodiment approach 3

[0039] Embodiment 3: The difference between this embodiment and the machine vision-based automatic tracking and monitoring system described in Embodiment 1 is that the first micro vision system 1, the second micro vision system 2 and the first micro vision system The three microscopic vision systems 3 are all realized by using a 10x microscopic objective lens 1-1, a coaxial lighting source 1-2, a CCD camera 1-3, and a focusing electric translation stage.

[0040] In this embodiment, the point light source in the microscopic vision system is used as a coaxial light source through the light source socket of the microscope lens, and illuminates the upper side of the target pill through a 45-degree reflector to provide illumination for the on-road camera, so that the CCD can accurately monitor the outline of the target pill and the gas-filled tube. Clear imaging, each microscopic vision system realizes precise position adjustment through the electric focusing platform.

It includes 3 microscopic vision systems, inflatable tube fine-tuning auxiliary clamping parts, mirrors, negative pressure adsorption head, and target pellet micro-adjustment platform; the negative pressure adsorption head is placed on the target pellet micro-adjustment platform, and the negative pressure adsorption head is used for Adsorption target pill, a microscopic vision system is used to image the target pill through the reflection of the mirror, and monitor the position of the target hole on the target pill. degree angle, the two-way system monitors the spatial position and attitude of the inflatable tube. It is mainly used for the assembly of target pellets and gas tubes.

Description

technical field [0001] The invention belongs to the field of automatic assembly of targets in inertial confinement fusion (ICF). Background technique [0002] The idea of ​​inertial confinement fusion (ICF) is to use high-energy particle beams to compress deuterium-tritium target pellets to a high density of several hundred grams per cubic centimeter within a few nanoseconds, and the pressure is hundreds of millions of atmospheres, so that the target pellets are locally Forms hot spots that ignite and burn. In the late 1980s, American scientists successfully drove inertial confinement nuclear fusion using the radiation energy of underground nuclear explosions, confirming the feasibility of this technical route. [0003] With the emergence of laser technology, people began to study the use of high power density and excellent directivity of strong lasers to bombard deuterium-tritium targets, allowing them to produce controlled inertial confinement nuclear fusion to release fu...
