What can a 2D camera detect?
The reference mentioned that the 2D camera can be used to detect the location of the library, such as detecting the four small rectangular boxes of the library, obtaining the corner of the library, the corresponding position of the library in the actual position of the whole image, trimming the image and expanding and performing contour detection.(Upper left, upper right, lower right, and lower left) to obtain six points of each outline (red is the point of the required pel). It can also be used for the pel detection in the target detection project. For example, a 2D bounding box can be obtained through the Yolo model, and its center point coordinates (center_x, center_y) and size pel detection. The center point of the 2D bounding box corresponds to the pel point in the image, and the depth value (Z value) of the pel point can also be obtained through the depth image.

It can easily detect the accuracy of the camera lens.
If you want to check the accuracy of the camera lens, you can use the following methods: 1. ** Using the 550 to check the autofocus accuracy of the lens (whether it is out of focus)**: The camera body is fixed on the frame, and the autofocus is aimed at the target. Then, press the MV Check LV button to enlarge the target. The focus situation is clear at a glance. 2. ** For the lens accuracy test in machine vision inspection: - ** In terms of resolution **: The resolution of a CCD-based camera is an important indicator for visual measurement and visual inspection systems. The higher the resolution of the camera used, the higher the resolution of the surface of the object, and the higher the detection accuracy of the system. In machine vision measurement, the resolution of the acquired image is the decisive factor to provide high accuracy and low uncertainty. A specific application requires enough pixelation to ensure accuracy. In order to make a repetitive and reliable measurement, a measuring instrument with a minimum measurement unit of one-tenth of the required measurement tolerance must be used. Sometimes, multiple cameras, professional cameras (such as line scan imagers), or multiple views of a single component may be needed to achieve the resolution required for the specified inspection tolerance. - ** In terms of camera selection **: - ** focal length **: The focal length of the industrial camera lens of the machine vision inspection equipment is related to the working distance of the industrial camera lens, the system's resolution (and the resolution of the CCD-camera). When choosing a lens, one had to consider different types of focal length characteristics such as fixed focal length (with an aperture that could adjust the aperture size to adapt to changes in illumination, no aperture for stable light sources or cameras with electronic shutter speeds), and variable focal length (such as the common six times and ten times focal length lenses). - ** Image Dimension and Image Quality **: The image dimension of the selected lens should be compatible with the size of the camera's light-sensitive surface (following the principle of "the big fits the small"). In terms of image quality, focus on MTF and distortion, especially in measurement applications. - ** Aperture **: According to the aperture, it is divided into manual aperture lens and automatic aperture lens. If the environment is stable, the manual aperture lens is generally used (only one adjustment is required). On the contrary, the automatic aperture lens is used (industrial cameras with automatic aperture lens sockets must be equipped). The control signal for the automatic aperture lens can be divided into two types, namely, the control signal of the ADC and the control signal of the VIDEO. - ** Model of the lens **: The specifications of the lens are generally divided into 1/3 ", 1/2", and 2/3 ". The focal length of the lens is related to the angle of view of the lens under different specifications. In addition, the choice of illumination also had an impact on the accuracy of the lens. The appropriate light source illumination could improve the accuracy of the system. For example, the dual monocentric lens had certain advantages in high-precision inspection. It could greatly reduce distortion (within 0.1%), and the large depth of field could make the edges of the image clear and the measurement accuracy high. For example, the dual monocentric lens of the BT - 12 series could be used as a key component in high-precision inspection and precision measurement of machine vision. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to remember detect
The word "detect" could be memorized using the root memory method. The root of the word was " de "+" tect ", which together meant " remove the cover ", which could be understood as " detect ". For example," detect radioactive material " and " detect the massive changes " had this meaning. " Choose " was equally exciting. Everyone was welcome to read it!
How to detect plagiarized articles
To detect plagiarism, you need to conduct a text analysis. For details, you can refer to the following methods: 1. Check the structure of the article and the similarity between the passages. If the structure of the article is similar or some of the passages are the same, it may be plagiarized. 2. Check the way the author uses citations. For example, using expressions such as " it is said " or " it is reported " when using other people's works, or similar content to other people's works are all characteristics of plagiarism. 3. Check the language expression of the article, such as the similarity of vocabulary and sentence structure. If the language of the article is the same or very similar, it may be plagiarized. 4. Check the references used by the author. If the references are the same or very similar, it may be plagiarized. 5. Check the source of the article, such as the author, the publishing company, the publication date, etc. If the source of the article is the same or very similar, it may be plagiarized. These are some common methods to detect plagiarism, but it should be noted that these methods are not completely accurate in detecting plagiarism, so you need to be careful when using these methods.
What does CCTV detect?
CCTV inspection can detect various conditions and problems inside the pipeline, including the degree of damage, distortion, blockage, siltation, corrosion, etc. Through the camera robot's full-process camera inspection, it could clearly observe the internal situation of the pipeline, such as siltation, damage, collapse, and so on. CCTV inspection could also accurately locate the defects inside the pipeline, making it easy for maintenance personnel to formulate repair plans. In addition, CCTV detection could monitor the internal situation of the pipeline in real time, and could take timely measures to deal with emergencies. It had the characteristics of high efficiency and reliability. It could complete the inspection of the pipeline in a short time and improve the maintenance efficiency. Common application scenarios include acceptance of new pipes and maintenance of old pipes. As for the specific inspection content and cost, it needs to be determined according to factors such as the length, complexity, and maintenance needs of the pipeline. It is recommended to contact a professional pipeline CCTV inspection service supplier for more accurate information.
