cvat with segment anything 半自动标注
cou版的正常运行，gpu显存5G不够，运行就提示显存不够，换了pth-facebookresearch-sam-vit-l模型显存也不够。 附：更换不同尺度模型方法 https://github.com/opencv/cvat/issues/6189 Yes, it was probably because you changed the model name.I can no longer deploy different fine-tuned SAM models at the same time.Yes, deploying several SAM models at the same……Read More
我的2023
博士的前半个学期匆匆过去，今年做的大多数是基础性的工作，没有显著的成果。明年应该调整任务策略，避免多个长线任务并存，仔细考虑任务的拆分，让手头尽量保持2~3个预期之内且没有难点的任务，借此来维持正常研究进度汇报。

Introduction to Lattice Boltzmann Method
The Lattice Boltzmann Method (LBM) is a computational fluid dynamics (CFD) technique used to simulate fluid flow at a mesoscopic level. It is based on the kinetic theory of gases and solves the Boltzmann equation, which describes the behavior of particles in a fluid. In LBM, the fluid domain is divi……Read More
小实验装置搭建
2023.7.5 买的松香和焊锡丝到了，迫不及待取回来打算焊接下压力传感器调理芯片的电路板，结果发现烙铁头沾不上焊锡是烙铁头氧化的缘故，今晚再买个烙铁头，明天悄悄去实验室拿点砂纸打磨下试试吧 kk40的滑台配置步进电机的驱动器还需要写个控制程序，把手头的Ardiuno mega2560板子拿出来试下吧，3D打印机的计划要等把marlin固件的代码大致了解下再实现了 2024.5.22 转眼一年要过去了，装置在运动控制，压力采集，图像识别方面做出了很多改进。运动采集部分通过移植GRBL至当前装置，实现了串口通讯控制滑台位移，压力采集也解决了多线程图像显示及停止功能设计。 此处粘贴一个遇到的问题，……Read More
