Based on context alone High-speed cameras could be used to measure displacement. The principle was to continuously capture moving images of an object in a short period of time and determine the displacement according to the change in the position of the object in the image. First of all, high-speed cameras could shoot at very high frame rates, such as thousands of frames per second or even higher. When an object moves in the field of view, the position of the object will change between adjacent frames. Through precise image analysis technology, the coordinates of the object in each frame could be determined. When measuring displacement, a suitable coordinate system needed to be established. If it was a two-dimensional displacement measurement, a rectangular coordinate system could be used to determine the coordinate changes of the object in the x-axis and y-axis directions. Assuming that the coordinates of the object in the first frame are (x1, y1), and the coordinates in a subsequent frame are (x2, y2), then the displacement in the x direction is x = x2 - x1, and the displacement in the y direction is y = y2 - y1. The total displacement can be calculated according to the Pythagorean theorem: d =(x <2>+ y <2>). In practical applications, factors such as lens distortion and measurement errors also needed to be considered. In order to improve the accuracy of the measurement, multiple measurements could be taken to average the value, or more complicated calibration-and-compensation algorithms could be used. At the same time, the resolution of the high-speed camera would also affect the accuracy of the displacement measurement. A higher resolution would help to determine the position of the object more accurately. Read more exciting novels for free

Ten Years of Sword Debate on Mount Hua

In Jin Yong's martial arts novels, the Huashan Sword Seminary was held once every twenty-five years. There was no such official setting as the " ten-year Huashan Sword Seminary ". However, if there was a sword tournament on Mount Hua that happened once every ten years, judging from the development of the characters 'martial arts, the rise and fall of the sects, and the structure of the Jianghu, it would greatly change the distribution of power and the relationship between the characters in the Jianghu. For example, some young masters might have more opportunities to stand out. Guo Jing, for example, had made a great leap in martial arts in a relatively short period of time. If the Sword Seminary was held once every ten years, he might have participated earlier and influenced the outcome of the Sword Seminary. Some old masters, such as Huang Yaoshi, also needed to constantly improve their martial arts to deal with more frequent challenges. In terms of sects, Beggar's Sect and other large sects might speed up the training of new people to participate in the competition. Some small sects might use this more frequent event to increase their popularity and influence. However, since there was no such setting in the original novel, this was only a speculation based on the original concept of the Huashan Sword Seminar.
