视频捕获卡 meaning in Chinese
video capture card
Examples
- Research method of video capture card in multi - channel data acquisition ' s system
多通道数据采集系统中视频捕获卡的研究 - Design and implementation of the driver for the multi - channel video - capture card driver based on the platform of linux
4视频捕获卡驱动程序的设计与实现 - Due to the sole - designed of the low voltage startup and power testing , for combined with the other four modules , we built the hardware and software flats , it was also convenient for continued extension . but , if there was different system wanted to combined in this system , we must redesigned all the hardware and software , it was a very hard work and could bring incompatibility . for this instance , the text designed a suit of number discriminating embedding system
但是如果有不同类型的系统也要增加到本系统中的话，就需要重新设计软硬件，工作量很大，还容易产生不兼容等问题，针对这种情况，本文设计了一套数字识别的电器安全测试嵌入式系统，可以面向多台仪器装置，不采用电气的连接，即是不改变原来的仪器装置，通过电压耦合元件摄像头和视频捕获卡从测量仪器的显示屏幕获取测试信息，再把信息传送到原来系统，从而组成了一个新的系统。 - The algorithm of image processing is the key . due to anomalous welding seam , the intensive arc light , random breaking of the bubble and gathering of the gas in the welding area , the seam images captured contain a lot of noise . in this case the noise must be removed and the welding seam is positioned accurately
本系统的图像处理部分采用了ccd摄像头和视频捕获卡，图像处理的算法是最关键的部分，由于焊缝图像并不是十分规则，而且在焊接时还会受到强烈弧光、飞溅和工件表面状况的影响，因此在这种情况下，必须有效的排除干扰把焊缝的中心位置准确找出来。
