视频卡的应用领域是非常广泛的。作者曾利用各种视频卡开发过多个在线检测和识别的实际系统,如保龄球自动计分系统,微循环尺寸和速度的检测,洗衣粉中荧光成份检测和热钢板优化剪切与控制系统等。下面分别以监视、计量检测、娱乐和医疗观察为例介绍视频卡的应用。 1.多点监视 如图1,摄像机输出信号经射频调制后单线(75欧同轴电缆)传输,通过电视被计算机接收,使用Trident9685显示,在大屏幕电视机上多点切换显示。由于采用了廉价的RF调制器,成本低,可靠性高。还可以用软件实现自动运动目标识别,一
The application of video card is very extensive. The authors have used a variety of video cards to develop real-world systems for on-line inspection and recognition such as bowling automatic scoring systems, detection of microcirculation size and speed, detection of fluorescent constituents in laundry detergent and optimization of hot plate cutting and control systems . The following are the monitoring, measurement testing, entertainment and medical observation as an example to introduce the application of video card. 1. Multi-point monitoring As shown in Figure 1, the camera output signal is modulated by a single line (75 ohm coaxial cable) after RF modulation and received by the computer through a television. The camera is switched over using the Trident 9685 display and multi-point switching on the large-screen television. Low cost and high reliability thanks to the cheap RF modulator. You can also use software to achieve automatic movement target recognition, a
