A sword is a sword. There is no difference between a wooden sword and a copper sword

   The sword Saint gannie once said ：“ A sword is a sword , Wooden sword 、 There is no difference between copper swords .”
   The sword , For the sword Saint gannie , Just a tool in hand , There is no good or bad . This is the understanding of the sword Saint gainie ！
   Jin Yong's 《 The Brave Archer and His Mate 》 There are similar descriptions , Book No 26 Wrote back the four levels of understanding of sword by sword demons in their lonely pursuit of defeat , These four levels use four swords as carriers !
   The first sword is to seek defeat alone 20 Used before the age of , This sword is about four feet long , The green light is shining , It's a sharp weapon . The evaluation of this sword is “ Fierce and fierce , invulnerable , Before the weak crown, they fought with the heroes of Heshuo .”
   The second sword is to seek defeat alone 20~30 Years old , This sword is called crape myrtle soft sword , Later, it was unlucky to hurt a righteous man by mistake , The deep valley of being abandoned . As you can imagine , Ziwei soft sword must be a sharp weapon in the world , It should be characterized by profit 、 light 、 fast .
   The third sword is to seek defeat alone 30~40 Years old , This sword is extremely heavy , The weight is no less than 70 or 80 Jin , Three feet long , The dark body of the sword , The blades on both sides are blunt , The tip of the sword is more round, like a hemisphere . Look at it from the conventional perspective of martial arts practitioners , It's easy to use the sword , This sword is too heavy , And the sword tip and blade are open , How to make ？ The evaluation of this sword is “ A heavy sword has no edge , It's a coincidence . Forty years ago, I relied on it .”
   The fourth sword is a wooden sword , To seek defeat alone 40 Used after the age of . After forty years of age , Not stagnant in things , Grass, wood, bamboo and stone are all swords , Gradually, no sword wins the realm with sword .
   The level represented by the fourth sword , His understanding of sword is similar to that of the sword Saint gainie , They all use the sword as a tool , It doesn't stick to the sword . They ignore the sword itself , What I care about is the method and strategy of using the sword .
   thus , I think of my industry ── Industrial visual inspection .
   In the field of industrial visual inspection , To provide customers with a complete industrial vision detection system . As a system , It must consist of many different parts , And the pursuit is stability and reliability . Generally speaking , Industrial vision inspection system includes image acquisition part 、 Image processing section and motion control section . These three parts are indispensable , There is no difference between light and heavy . As an image algorithm engineer , Work related to image processing . Deep learning algorithms are often used in image processing , Such as YOLOv3、YOLOv4、YOLOv5 etc. . Theoretically , In the open dataset （ Such as VOC、COCO） On ,YOLOv3、YOLOv4、YOLOv5 The accuracy increases in turn . But sometimes , On a small dataset ,YOLOv3、YOLOv4、YOLOv5 The performance is also close to . here , The author asked ,YOLOv3、YOLOv4 and YOLOv5 What's the difference in image processing ？ They are just an algorithm , A tool , Are used to solve image processing tasks . so to speak , No difference .
   Jump out of the field of industrial visual inspection , From the perspective of life .1000 ten thousand 、100 ten thousand 、10 What's the difference between 10000 cars ？ They're just vehicles .3 ten thousand 、3 Qianhe 300 What's the difference between your bag ？ They are just tools for holding things .
   A sword is a sword , Wooden sword 、 There is no difference between copper swords . The sword is just a tool , The only difference is the person who uses the sword ！
