RealsenseD435i+Python+PyQt窗体应用程序(基础篇)

资源包包含一个pycharm工程，其中包含两个.py文件，展示了Intel公司的RealsenseD435i深度相机API的基本操作，结合PyQt制作了基本的窗体应用程序。主要内容：D435i深度相机数据流的开启、RGB图和深度图的获取与对准、深度图的后处理、IMU数据的获取和相机姿态的绘制、相关的PyQt窗体界面的设计等等。希望该资源能够帮助到大家！

To draw a 100k point graph using PyQt, you can use the following controls: 1. QGraphicsView: This widget provides a viewport for displaying the graph. It allows you to scroll and zoom in/out of the graph. You can also add custom items to the view, such as lines and points. 2. QPen/QBrush: These classes allow you to define the style of the lines and points in the graph. You can specify the color, thickness, and other properties. 3. QPolygonF: This class represents a polygon with floating-point coordinates. You can use it to draw lines and points on the graph. 4. QTimer: This class allows you to create a timer that can trigger events at regular intervals. You can use it to update the graph periodically, for example, to animate the data or to display real-time data. 5. QThread: This class allows you to run code in a separate thread, which is useful for long-running calculations or data processing. You can use it to generate or manipulate the data for the graph without blocking the user interface. 6. QScrollBar: This widget allows you to add scrollbars to the QGraphicsView, which is useful when the graph is larger than the viewport. 7. QGridLayout: This layout manager allows you to arrange the widgets in a grid. You can use it to position the QGraphicsView and other controls on the main window. By using these controls, you can create a custom graph widget that can handle large datasets and provide a smooth user experience.
