摄像机

In this paper, instead of corresponding image points which are widely used in the literature, corresponding image conics are used to calibrate a rotating camera.

摘要研究探讨了一种基于平面二次曲线的纯旋转摄像机自标定方法。

This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.

这种非接触的测量方式，采用RAC两步法对摄像机进行标定，然后对采集到的钢板图像进行分析处理，通过多项式插值的方法，采用具有保持边缘特征和滤波功能，且能适应非均匀照明的十字窗图像边缘检测算子进行象素级边缘检测，再用最小二乘拟合法和逆透视法对二维图像进行三维重建，便可测出钢板上给定点的距离及其变化值，以期为水火弯板的变形机理研究提供一种新的检测手段。

The collimator neutron flux is drawn from the horizontal channel by the use of SPRR-300 as a neutron resource. The convector made of 6LiFZnS and the long focus professional twilight lens with the small field of view are used, and the digitalized CCD camera is developed by the use of scientific grade CCD chip, the double thermocouple refrigeration and 14bit A/D convector. The image grabbing, processing and analyzing software of double bytes has been developed by the use of Visual C++ and C++ Builder, and the facility of anti-radiation for CCD is set up.

With the development of missile defense system,the penetration of ballistic missile will faces with a greater menace,and the midcourse of ballistic missile is the focus of countermine.

"国防支援计划"系统是由美国空军的空间和导弹系统中心研制的预警卫星系统，属于同步轨道导弹预警卫星，提供24h全球监视，载有红外传感器、电视摄像机和核爆炸探测器等设备，主要用于导弹预警和核爆炸探测。

The Courier-Mail reports descriptions of the three unmarked vehicles containing the hidden cameras are such closely guarded secrets that not even the Queensland Police Minister knows what they look like.

据Courier - Mail报道，三辆载有隐藏测速摄像机的没有任何标志的车辆的信息作为一项被严格保守的机密，以至于连昆士兰警察部长也不知道它们看上去象什么样子。

I'd love to hear more of your theory,but I don't give a cra also the pillcam's back.

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。
