The quality of a table tennis racket could not be judged by the same standard. It had to be judged according to the level and needs of the user. - For beginners, because they mainly wanted to learn the movements, they didn't have high requirements for the feel of the racket and often bumped into the racket. They didn't need to buy an expensive racket. They could just choose a finished racket that cost about 50 to 60 yuan. - People who had a certain foundation, had basic control over the movements, and had begun to feel the beat in their hands, and no longer often bumped the beat, using a finished product that cost about 100 yuan was enough. - Those who had some basic skills, had basically fixed movements, and had begun to use friction techniques to play could buy a better bottom plate and match it with a low-cost rubber (under the guidance of a coach) to assemble the racket. - Those who had reached a certain level of learning basketball, had solid basic skills and certain offensive and defensive skills, and had their own understanding of rackets could buy low-end products from big brands under the guidance of their coaches and spend about 1,000 yuan to satisfy their hobbies. - Those who often participated in competitions and valued competition results could consult professional coaches and buy high-end products from big brands that suited their characteristics. - The equipment of professional table tennis players must be customized by professional coaches.

The selection of a machine vision camera requires consideration of the following aspects: ** 1. Type of camera ** 1. ** Line Array Industrial Cameras ** - It was suitable for capturing continuous, long production lines. For example, detecting problems on the roller, or scenes that required a large field of view or extremely high precision. It worked with an extremely long and narrow imaging feature, and the field of view was a slender strip. 2. ** Array camera ** - It was more suitable for capturing the entire scene. 3. **3D camera ** - It is suitable for specific scenarios that require 3D information acquisition. For example, in the 3D machine vision camera market research, it will involve the market size (production capacity, output, sales, output value, price, cost, profit, etc.) and industry competition analysis (raw materials, market applications, product types, market demand, market supply, downstream market analysis, supply chain analysis, major companies, market share, M & A, expansion, etc.). ** 2. Signal Type ** 1. ** Simulation camera ** - An image acquisition card was required. The resolution of a standard simulated camera was very low, usually 768 x 576, and the frame rate was fixed (25 frames per second). The data collected was an analogy signal, which was converted into a digital signal by the digital acquisition card for transmission and storage. However, it is susceptible to distortion caused by electromagnetic noise interference from other equipment in the factory (such as electric motor or high-voltage cable). As the noise level increases, its dynamic range (the ratio of the original signal to noise) will decrease, affecting the amount of information transmitted to the computer. 2. ** Digital camera ** - What was collected was a digital signal that was not affected by electromagnetic noise. The dynamic range was higher, and it could transmit more accurate signals to the computer. ** 3. Determination ** The resolution of the camera was chosen according to the system's requirements. For example, to detect the scratches on the surface of an object, the size of the object required to be shot was 10mm × 8mm, and the required detection accuracy was 0.01mm. Assuming that the field of view to be shot was 12mm × 10mm, then the camera that should be chosen had a minimum resolution of (12/0.01)×(10/0.01) = 1200x1000, which was about 1.2 million pixels. Generally, the lowest resolution camera required was determined according to the actual accuracy inspection requirements. The common camera had 1.3 million resolution to choose from. ** 4. Chip Type ** 1. ** Charge Coupled Device (CCD-Chip) camera ** - If the object to be shot is moving and the object to be processed is also moving in real-time, it is more suitable to choose a camera with a CCD-chip. 2. ** Complimentary Metal Oxide Silicon (LCD) chip camera ** - If the object being photographed was moving very slowly, the distance of the object's movement was very small within the set exposure time of the camera, which was converted to a 1 - 2-pixel-sized image, then the use of a LCD camera was also suitable (if not for measurement). Moreover, if the manufacturer's LCD camera used the frame exposure method, it could also be used as a CCD. However, if the deviation was more than 2 px (caused by the movement of the object), the image taken by the object would have smear, so it was not suitable to choose a LCD camera. ** 5. Other Key Elements ** The frame rate, color depth, dynamic range, and sensitivity of the camera were key factors in the selection. The quality of the lens, the optical format of the camera, the number of graphics, and the type of interface (such as USB, ether, or GigE) were also considerations that could not be ignored when selecting the camera. At the same time, for the line array industrial camera, parameters such as line frequency, line height, and trigger method also needed to be considered. The line frequency was the camera's shooting speed, and the line height was based on the application requirements to determine how many lines to capture an image (that is, the image's "high" resolution). The trigger methods were line trigger (suitable for scenes where the motion speed was not uniform or required some special imaging technology, such as long and short exposure HVR, time-sharing stroboscopic, etc.) and frame trigger (suitable for shooting objects with relatively uniform motion. After the frame trigger, the line array camera would continue to shoot at the set line frequency until it reached the specified line height). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Legend of Zhen Huan was one of the representative works of the online writer Liu Lianzi. It was a long palace novel inspired by the Golden Branch. In 2011, with the help of director Zheng Xiaolong and screenwriter, the novel was adapted into a TV series of the same name. The novel was set in the fictional Great Zhou Dynasty. It narrated Zhen Huan's growth process from entering the harem to becoming the Empress Dowager. It created the image of many harem women fighting for power and survival under the feudal royal power. It examined and criticized the historical view of power from the perspective of human nature. The TV series adapted some of the content of the original work. For example, in the original work, the emperor did not fall in love with Zhen Huan. After returning to the palace, she still carried the title of "Concubine Guan", which symbolized a substitute. In the drama version, the emperor fell in love with Zhen Huan and was called "Concubine Xi" after returning to the palace. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
