物体位姿估计综述英文Overview of Object Pose Estimation.Object pose estimation is a crucial task in computer vision, aiming to determine the position and orientation of objects in a given scene. It plays a pivotal role in various applications, ranging from augmented reality to robotics and autonomous driving. This article presents a comprehensive overview of object pose estimation, discussing its importance, methods, challenges, and future trends.Importance of Object Pose Estimation.Object pose estimation is essential for understanding and interacting with the physical world. It enables systems to perceive the three-dimensional position and orientation of objects accurately, enabling precise manipulation, localization, and tracking. In augmented reality, pose estimation is crucial for overlaying virtual objects ontothe real world. In robotics, it enables robots to grasp, manipulate, and interact with objects effectively. In autonomous driving, pose estimation is vital for perceiving the position and orientation of vehicles and pedestrians to ensure safe navigation.Methods of Object Pose Estimation.Object pose estimation can be categorized into two broad approaches: template-based methods and learning-based methods.Template-based methods involve the creation of a 3D model or template of the object and matching it with the observed 2D image to estimate the pose. One popular algorithm is the Iterative Closest Point (ICP), whichaligns the 3D model with the 2D image by minimizing the distances between corresponding points. Template-based methods are accurate but computationally expensive and limited to known object categories.Learning-based methods, on the other hand, utilize deeplearning techniques to learn pose estimation directly from data. Convolutional Neural Networks (CNNs) are commonly used to extract features from images, and pose estimationis performed using regression or classification tasks. Methods like PoseNet and PVNet have achieved remarkable results in recent years. Learning-based methods are more flexible and can handle unknown object categories but require large amounts of labeled data for training.Challenges in Object Pose Estimation.Object pose estimation faces several challenges, including occlusion, cluttered scenes, and varying lighting conditions. Occlusion occurs when objects overlap or are partially hidden, making it difficult to extract sufficient information for pose estimation. Cluttered scenes present a challenge due to the presence of multiple objects, makingit difficult to separate and identify individual objects. Varying lighting conditions can affect the appearance of objects, leading to inaccuracies in pose estimation.Another challenge is the diversity of object shapes andsizes. Different objects have unique geometric properties that require specific approaches for accurate pose estimation. Additionally, pose estimation is oftensensitive to noise and outliers in the input data, which can affect the accuracy of the estimated pose.Future Trends in Object Pose Estimation.With the advancements in deep learning and computer vision, object pose estimation is expected to evolvefurther in the coming years. One promising direction is the integration of sensor data, such as depth sensors or RGB-D cameras, to enhance pose estimation accuracy in complex environments. Multi-modal data fusion can provideadditional information about object geometry and depth, leading to more robust pose estimation.Another trend is the utilization of larger and more diverse datasets for training deep learning models. This will enable the development of more generalizable and robust pose estimation algorithms that can handle a wide range of object categories and environments.Finally, real-time pose estimation is an important direction for future research. Many applications, such as augmented reality and robotics, require pose estimation to be performed in real-time, enabling fast and responsive interactions. The development of efficient algorithms and hardware optimizations can lead to significant improvements in real-time pose estimation capabilities.In conclusion, object pose estimation is a crucial task in computer vision with widespread applications. It involves the estimation of the position and orientation of objects in a given scene, enabling precise manipulation, localization, and tracking. Template-based and learning-based methods are commonly used for pose estimation, each with its own advantages and limitations. Challenges such as occlusion, cluttered scenes, and varying lighting conditions need to be addressed to improve pose estimation accuracy. Future trends include the integration of sensor data, utilization of larger and more diverse datasets, and the development of real-time pose estimation algorithms. With continued research and advancements in this field,object pose estimation is expected to play a pivotal role in enabling more intelligent and responsive interactions with the physical world.。

顶点构成四边形英语The Formation of Quadrilaterals by Vertices.Quadrilaterals, a fundamental geometric shape, are enclosed by four straight lines, creating four angles and four sides. These four sides are connected by four vertices, each serving as a point where two or more lines intersect. The study of how these vertices come together to form a quadrilateral is an essential aspect of geometry, providing insights into the properties and characteristics of this shape.To understand how vertices construct a quadrilateral,it's crucial to first grasp the basic elements of a quadrilateral. A quadrilateral can be defined as a closed two-dimensional figure with four sides and four vertices. These sides can vary in length, and the angles between them can be acute, obtuse, or right angles. Depending on the lengths of the sides and the measures of the angles, quadrilaterals can be further classified into specifictypes such as rectangles, squares, trapezoids, and parallelograms.Vertices play a crucial role in determining the shape and properties of a quadrilateral. Each vertex represents a point of intersection where two line segments, or sides, meet. The positioning of these vertices relative to each other determines the overall shape and structure of the quadrilateral. For example, in a rectangle, the vertices are positioned such that the opposite sides are parallel and equal in length, resulting in right angles at each vertex.The connections between the vertices are not just mathematical abstractions; they have practical applications in real-world scenarios. In architecture, the vertices of a quadrilateral can represent the corners of a room or the junctions of beams and supports in a bridge. In computer graphics, vertices are used to define the shape andposition of objects, enabling precise rendering and animation.To form a valid quadrilateral, the vertices must be arranged in such a way that they can be connected by four distinct line segments. These line segments, known as edges, must not intersect each other except at the vertices, ensuring that the shape is closed and well-defined. If the edges intersect at points other than the vertices, theshape would no longer be considered a valid quadrilateral.The positions of the vertices can be represented using coordinate geometry, where each vertex is assigned aspecific position in a two-dimensional plane. By knowingthe coordinates of the vertices, it's possible to calculate the lengths of the sides, the measures of the angles, and other geometric properties of the quadrilateral. This approach is particularly useful in advanced geometry and related fields such as trigonometry and analytic geometry.In summary, the vertices of a quadrilateral play a pivotal role in its formation and properties. They serve as the fundamental building blocks of this geometric shape, defining its shape, size, and characteristics. The study of how these vertices come together to create a quadrilateralis not just an academic exercise; it has practical implications in various fields, from architecture to computer graphics. By understanding the role of vertices in quadrilateral formation, we gain a deeper understanding of the principles and applications of geometry in our daily lives.。

可控硅相位控制原理English:The principle of phase control in a thyristor, also known as a silicon-controlled rectifier (SCR), involves controlling the firing angle of the thyristor to regulate the power delivered to a load. The thyristor is a four-layer, three-junction semiconductor device that can only conduct current when triggered into its conducting state. The control of the firing angle is achieved through the application of a gate pulse at the gate terminal of the SCR.When an AC voltage is applied to the input terminals of the thyristor circuit, initially the thyristor blocks the current flow as it is in its non-conducting state. In order to trigger the thyristor into conduction, a gate pulse is applied at the gate terminal. The gate pulse is generally a short-duration, low-voltage signal synchronized to the AC waveform. When the gate pulse is applied within a particular time window, which corresponds to the desired firing angle, the thyristor gets triggered into conduction, allowing the load current to flow.By controlling the phase angle at which the gate pulse is applied, the firing angle of the thyristor can be adjusted. This determines the point in the AC waveform at which the thyristor starts conducting. As the firing angle is reduced, the thyristor conducts for a longer duration during each half-cycle of the AC waveform, resulting in increased power delivery to the load. Conversely, increasing the firing angle reduces the conduction duration and decreases the power delivered to the load.The controlled firing angle allows for efficient power control in applications like motor speed control, light dimming, and power factor correction. Additionally, phase control helps in the reduction of harmonic distortions and minimizes the generation of electromagnetic interference. With the appropriate gate pulse triggering, the thyristor can be turned on and off at specific points in the AC waveform, enabling precise control over power delivery.中文翻译:可控硅的相位控制原理，也称为硅控整流器（SCR），涉及通过控制可控硅的触发角以调节传送给负载的功率。

DO YOU NEED A RUDDER FEEDBACK UNIT?For reliable and accurate auto-steering, your autopilot computer must also keep track of your rudder position, a rudder feedback unit provides that data. On smaller boats, Virtual Rudder Feedback (VRF) eliminates the need to install a physical sensor by using a software-based approach to calculate rudder position.Rudder Feedback Units are typically used on larger boats or boats with inboard engines. A rudder feedback unitphysically connects to your rudder, continually measures its position, and reports it to your autopilot computer.Boats with commercial electronic steering (e.g. Volvo IPS, Optimus EPS etc.) may not require a rudder feedback unit as this feedback is integrated into the existing system. There are Simrad autopilot solutions with Virtual Rudder Feedback (VRF) options.3. YOUR DRIVE SELECTION DICTATES YOUR AUTOPILOT COMPUTERWhether you command your autopilot via multifunction display, dedicated autopilot controller or remote control, there’s an autopilot computer siting below deck that continuously monitors data from compasses, rudderfeedback units and other on board instruments. Our autopilotcomputers also looks at your current heading and works out how to move the rudder or outboard.Depending on the size of your boat and drive unit required, you’ll either need a standard or high-current computer.A) A reversible hydraulic steering pump is used to add autopilot capabilities to outboard or sterndrive (inboard/outboard) vessels with existing hydraulic steering systems. Larger boats need larger pumps; your choice of pump will decide whether you need a standard NAC-2 or high-current NAC-3 autopilot computer.Locate the hydraulic RAM on your engine and check the label for the cylinder capacity (cubic inches or cc)Tip on how to identify what kind of steering mechanism your boat has……B) Helm drives and linear rams are used to add autopilot capabilities to vessels with mechanical (non-hydraulic) steering systems.• Electronic helm drive units suit smaller cable steered runabouts.• Linear rams operate rudders on power-driven boats, or steering quadrants on sailing vessels.Helm drives and smaller rams work with a standard NAC-2 autopilot computer; more powerful rams for larger vessels are driven by a high-current NAC-3 autopilot computer.4. CHOOSE YOUR CONTROLLER – IT’S UP TO YOU!With a Simrad autopilot, the choice of display (controller)is up to you. Dedicated controllers offer an always-visible display and instantaneous control at the touch of a button. It’s also possible to control your autopilot system using a Simrad multifunction display for an on-screen touch interface.
