选通技术 meaning in English
gating technique
Examples
- Ccd ) , light signals from the object is covered by relay scattering when laser beam penetrates through the atmosphere . so the technique of range gate has been used in such system
当激光通过大气时，瑞利散射将使得ccd器件接收到的目标回波信号淹没在噪声信号之中，因此系统中采用了距离选通技术。 - It is difficult to get the car plate picture . while , at the same time , we use a more powerful light in a limited range of spectrum to head on the car light , basing on the technology of the selecting and use a filter to filter the unnecessary light , we can get the clear car picture
如果，在拍摄车牌图像的同时，用一特定光谱范围内，辐射功率大于车灯辐射功率的光源，向车牌方向照射，利用光谱的选通技术，通过摄像机端的滤光片滤去车灯发出的不需要的辐射，摄像机就可以拍摄到的较为清晰的车牌图像了。 - All of above make the miss distance of the missile difficult to estimate in shooting range . in order to solve these problems , a novel method for detecting and tracking small moving point target in image sequence is proposed in this paper , based on combination of the correlation of multi - frames and wave gate techniques . especially , the qualifications to confirm the target and the establishment of the wave gate based on size and characteristic moving parameters of the target are stressed in the paper
针对目前靶场所面临的测量目标小、距离远、目标与背景对比度小,不具有形状信息的实际问题,提出了一种基于多帧相关技术与波门选通技术相结合的快速目标识别与跟踪方法,特别探讨了多帧相关技术中目标确定的理论判据,并综合考虑目标的尺寸因素和目标的运动特征研究了一种新的波门设定方案。
