Python / OpenCV速度检测器 这是一个使用OpenCV从交通摄像头实时流中计算汽车速度的程序。 这个怎么运作 该演示gif在说明中将被多次引用,因此我将其保留在此处。 播种 我的程序对视频所做的第一件事是裁剪出所有不必要的区域。 在下面的gif中,黑框遮挡了屏幕上有运动的一部分,但不应该将其包括在我们的检测范围之内。 可以在运行时手动选择这些裁剪的区域(在“源图像”窗口上单击并拖动),并将其保存在settings.json (按's'键时)。 启动时将裁剪出保存的区域。 车辆检测 现在,不需要的区域已被移除,我们可以使用计算机视觉来隔离车辆(毕竟,这是我们真正关心的!)。 我使用KNN背景减法和形态学来隔离车辆并检测其轮廓。 由于这些是默认的OpenCV函数,因此我将不做过多解释,但是您可以在main.py的process_frame()和filter_mask()的第一部分

约翰逊的又一本SI力作,介绍如下: Raves for Dr. Johnson's previous classic, High-Speed Digital Design! "....one of the finest efforts to come along in the field of applied high-speed digital design because of its focus on providing tools for the whole design team bringing a high-speed product to life. For all the PCB designers and circuit designers out there, buy it; read it; keep it." -Dan Baumgartner, Printed Circuit Design In High-Speed Signal Propagation, Howard Johnson and Martin Graham bring together state-of-the-art techniques for building digital interconnections that can transmit faster, farther, and more efficiently than ever before. Packed with new examples and never-before-published high-speed design guidance, this book offers a complete and unified theory of signal propagation for all metallic media, from cables to pcb traces to chips. Coverage includes: Managing tradeoffs between speed and distance Physical theory of signal impairments: skin and proximity effects, dielectric loss, surface roughness, and non-TEM mode propagation Generalized frequency- and step-response models Calculation of time-domain waveforms from frequency-domain transfer functions Differential signaling: Edge-coupled and broadside-coupled differential pairs, bends, intra-pair skew, differential trace geometry impedance, crosstalk, and radiation Inter-cabinet connections: Coax, twisted-pair, fiber, equalizers, and LAN building wiring Clock distribution: Special requirements, repeaters, multi-drop clock distribution, jitter, and power filtering Simulation: Frequency domain simulation methods, Spice, and IBIS
