camera optical parameters
The optical parameters of the camera included the following aspects: 1. ** focal length **: This is a very important optical parameters of the lens. It refers to the distance from the main point of the lens to the focal point. It is an important performance indicator of the lens. The length of the focal length of the lens was inverse to the size of the image taken by the lens. That is, under the same object distance, the larger the focal length of the lens, the smaller the size of the image taken. Most industrial cameras use fixed-focus lenses in practical applications. Before choosing the focal length of the lens, you need to know the object distance of the on-site camera (the installation height of the camera lens from the surface of the measured object) and the field of view of the camera (the size of the characteristics of the measured object). In some applications involving the mixed inspection of objects at different heights, the use of a variable focal length lens would be considered. However, the variable focal length lens had two issues to consider: zooming speed and lens life. 2. ** Depth-of-field **: When the focal length of the lens is adjusted to a focal point, only the objects within a certain distance before and after the focal point are clearly visible. The objects outside this distance are blurred. This distance is the depth of field of the lens. 3. ** Pieces and resolution **: Pieces are the smallest unit of an image generated by the imaging chip, such as a 2-million-pel image. The resolution referred to the imaging ability of the CCD-or CMOS-chip. For example, the resolution of a 2-million-pel camera was 1626 x 1236, which meant that the camera had 1626 x 1236 rows in the X-axis direction. The total image taken was about 2 million pel. The detection accuracy could be simply evaluated by dividing the actual size of the image's X-axis by the number of X-axis dots. However, the final detection accuracy was affected by many factors, including the moving speed of the object being measured, light interference, the shape of the object, the contrast of the features, the computing power of the software, and so on. 4. ** Picture element size **: This is also an important optical parameters of the camera. 5. ** Target size of sensor **: It is the most concerned part of the camera's optical parameters.

The perfect husband suspense novel online free of charge
I recommend " Scumbag Detection System " by Jing Ling. This was a super cool sci-fi space novel. Its original name was " Scumbag Destroys the System ", and it had been completed. In the story, the female protagonist had a system to detect scumbags, like " Are you being pestered by straight man cancer? Beep…scumbag rating of 99. Save or destroy?" This setting was very interesting. There were all kinds of plots in the book to punish scumbags, and there was a story about a sister who was abused by a scumbag fighting back. Although it was a little dark, it was both satisfying and thought-provoking, such as the definition of scum, saving or destroying which was justice, and so on. The plot was tight, the ending was unexpected, the female lead was stubborn, and there was no CP. There was also " National Time Travel: I Have a VIP at the Beginning ", a game novel that his senior was not in a hurry to write. The main character, Chen Nian, was the only player who paid to play. Others struggled to survive, but his character was super powerful in the game and his writing was good. " The Law of Wife-Hunting " was also very good. It was a fantasy romance novel written by Chan Kong. The female protagonist, Qiqi, has transmigrated to a strange world. It's a classic of the early beast culture. The characters are deeply portrayed. Don't miss it if you like the theme of beasts. There was also " Perfect Entertainment ", a novel about urban life written by the Unsullied Witch. After the main character was reborn, he broke all kinds of records in the parallel world and showed off. Finally," I Love Strangers " was a mystery detective novel. The secrets behind the gorgeous mansion were mind-blowing. Although the female lead was a little silly and had a hasty ending, the overall story was great. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is statins helpful for gallstones? Can they be eaten?
Generally speaking, patients with gallstones were not directly related to statins. Statins were mainly used to lower blood fat. They would not aggravate gallstones, nor would they induce diseases such as cholecystectomy caused by gallstones. Therefore, patients with gallstones could usually take statins by mouth. However, if patients with gallstones had bile stasis, abnormal liver function, or even liver failure, they could not take atrofates because the drug had adverse reactions that led to liver damage. It was prohibited for patients with abnormal liver function. Statins should be taken under the guidance of a doctor, and liver function indicators should be monitored regularly. From the perspective of helping gallstones, a study covering more than 600,000 people showed that because statins could suppress the synthesis of gallstones, the use of statins could reduce the risk of gallstones compared to non-users. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The female author of the novel is called Lin Qianqian
I recommend " Daily Life of a Reborn Female Supporting Character," by Ruolan. Lin Jiaojiao was dressed as a top-grade supporting actress and had a scamming system. The Lin family had many top-grade characters. She worked hard to complete missions and change herself in order to eat meat. The rebirth of the original female lead was a small turning point. This was Su Shuang's work. The female lead had high EQ and IQ. Although the theme was old-fashioned, it was innovative. The writing was smooth, and the male lead did not have a high sense of existence. " Family Cultivation: I Use Water to Farm in the Sea ", a Xianxia novel written by Yueye Shenyin. After Zhang Daoran transmigrated, he used the Water Spirit Avatar of the Chaos Origin Pearl to find immortal cultivation resources in the sea, raise sea beasts, and establish an immortal dynasty in the sea. " Don't Be Cannon Fodder ", a sci-fi space novel written by Lin Miaomiao. An Ran, the female protagonist, traveled through different worlds to fulfill her wish to obtain eternal life and reap a beautiful life in reality. The female lead was a growth-type, down-to-earth, and unpretentious. "The Dragon King of Jinghe River in the West," Huang Yige's work. The protagonist dressed as the Dragon King of the Jing River. In order to avoid becoming a chess piece, he controlled the rise of the Four Spirit Treasures and restored the dignity of the Dragon Clan. It was written by Lin Miaomiao. Linlang traveled in time and space, eating, drinking, and occasionally fulfilling other people's wishes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Moon God's Effect and Treatment
If the "Moon God" here referred to the Moon God Probiotic, it had many effects. It can help to improve digestive problems, relieve constipation, diarrhea and other intestinal discomfort; It can improve the body's immunity and improve the body's condition; It has a good suppressive effect on candida, escheril, and gardnerella. It can maintain the self-cleaning and self-purification ability of the anus, promote the balance of the anus, secrete substances such as actic acid and suppressive bacteria to improve the balance of the anus and the microecological environment, adjust the PH value, and rebuild the balance of the flora in the private part, thus reducing or preventing vaginosis and protecting women's health for a long time. However, the quality and effect of the product varied according to one's physique and usage. It was best to consult a doctor or nutritionist before using it, and follow the product instructions and recommended dosage. If the "Moon God" here referred to the Moon God in myths and legends (such as Chang'e in Chang'e's Journey to the Moon), Chang'e followed her husband to the human world to eliminate disasters and heal wounds for humans, but this was not the concept of efficacy in the modern medical sense. In the novel "Ancient Godly Emperor," the Moon Goddess saved the protagonist Zhang Ruochen's life and taught him many things. It was important in the development of the story, but it didn't have the effect of treating people in the modern sense.

Doomsday despair novel
I recommend a few apocalyptic novels. " Descending of Hell," a sci-fi novel created by QQ. " Mi Mo of Doomsday " was a futuristic sci-fi novel written by Mi Wenduo. The female protagonist was reborn into a ten-year-old girl after the outbreak of Resident Evil. However, some people couldn't read the first dozens of chapters and felt that the female lead was not likable. " Doomsday Summoning Frenzy " was written by the black-hearted Da Bai. It was a sci-fi doomsday crisis genre. There was no female protagonist, and the main character was not a saint. It was a new novel and had quite a bit of potential. It was considered pretty good among similar works. " Doomsday: The Abyss Summoner " was a sci-fi novel written by the author who had yet to warm up. It was a sci-fi novel that was related to doomsday crisis. The main character was decisive and not saintly. Although the author's previous works had a bad ending, this book was not bad at the moment. " Survive in a Rotten Nation ", written by Kiwifruit 008, a zombie survival novel. It was purely realistic without abilities and harem, but there were problems such as repeated plots and lack of common sense. Those who liked apocalyptic novels could read these novels.
