查询词典 camera angle

The Fresnel lens in the optical receptor spotlights the headlamp beams to form their image at the 1-meter distance between the optical receptor and headlamps. CMOS camera as an image sensor, takes the photos of their images, which are captured by VG-M201, The application of some digital image processing techniques to these images, such as edge-picking up、 least-square fitting-curve algorithm, is to calculate the offset position/angle of optical axis of the high beams and the nodical offset of the unsymmetrical facular light and shade cut-off line of the low beams.

系统的图像采集工作是利用受光箱中的菲涅耳透镜在1米的测量距离上聚合前照灯灯光，由CMOS摄像头作为图像传感器件，照入灯光远光光斑和非对称近光图像，由嵌入式处理器对捕获的图像运用边缘提取、最小二乘法拟合曲线等数字图像处理技术计算出远光主光轴偏移角度以及非对称近光光斑明暗截止线拐点的偏移，实现了前照灯近光非对称光斑的自动测量。

Such as: calibrating the laser system, calibrating the measurement region and focusing the CCD camera for the diffuser passage with complex shape, selecting the best incidence angle for the laser sheet,, setting the time parameter including the time between pulses and the time between records, designing the laser system, and selecting water fog with 1～5μm diameter as seedings for PIV measurement after comparing several particles. All of the work is useful to accumulate the PIV measurement experience in turbomachinery. 2. Experimental research of the unsteady flow in diffusers The instantaneous velocity fields within the vaneless and vaned diffuser were measured by using PIV technique.

本文在国内首次进行PIV测量系统对离心风机扩压器内部非定常流动的测量，为此，作者作了必要的实验前期工作：双谐振激光器工作特性的标定；针对扩压器复杂的流道形状，解决了片光源照射区域位置的标定和CCD相机的聚焦等问题；为复杂流道形状的扩压器内部流动的PIV测量选择了最佳片光源入射角度；选择了合适的PIV测量时间参数；为实现非定常内流的PIV测量设计了PIV系统的光路布置；根据非接触测量示踪粒子的选取原则，对几种示踪粒子进行了筛选，最终1～5μm的水雾粒子在本文实验条件下获得最佳效果。

Considering the angle sensor as the camera. and analogizing the theodolite measuring system to the photogrammetric system.

本文将经纬仪工业测量系统模拟摄影测量系统，把角度传感器视为摄影机，将物方点的角度观测值化算为虚拟像点坐标，从而按摄影测量光束法平差进行两台或多台经纬仪间的系统定向和空间坐标解算。

As they closed to within one hundred meters of the sputtering, partially disassembled drive coils, his rear-angle camera fuzzed with static.

他们飞到了离这个仍然在喷溅着火花的半解体的发动机线圈差不多100米的地方。库尔特的后视镜头因静电而模糊。

In some shots the apparent tilt angle was steepened using various tricks such as tilting the camera and horizon.

一些船明显倾斜的镜头都是用各种各样的技巧实现的，如旋转摄像机等。

If you're shooting film, bracket a lot to make sure of getting the exposure you want. With a digital camera, check the images as you shoot. Wide-angle lenses tend to work best because the blown-out sun takes up less of the image, but they are susceptible to lens flare.

如果使用胶片相机，务必多点测光确保得到正确的曝光量，如果是数码相机，拍摄后要检查图片，使用广角镜头更有效，因为高温的太阳在画面占据更小的面积，但广角镜头由于镜头反射容易引起成像模糊。

With a digital camera, check the images as you shoot. Wide-angle lenses tend to work best because the blown-out sun takes up less of the image, but they are susceptible to lens flare. The advantage of SLRs is that you can see the flare when you frame the image.

The next step is to set up your camera's viewing angle.

接下来要做的是设定摄像机角度（也就是我们目前视野的角度）。

Believe it or not , this new digital camera has a wide angle lens.

不管你信不信，这新的数位相机有广角镜头。

The camera can shoot any angle in front of the picture plane.

该相机可拍摄任何角度前面的图片飞机。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
