查询词典 Camera

Brandts, who appears hilariously to think the whole thing was her idea, explained:"We had our camera set up on some rocks and were getting ready to take the picture when this curious little ground squirrel appeared, became intrigued with the sound of the focusing camera and popped right into our shot."

勃兰茨似乎很捧腹地认为整件事情是她的主意，她解释道："我们把照相机架在岩石上，然后做好准备拍照，此时这个好奇的小地松鼠出现了，它对照相机对焦的声音产生了浓厚的兴趣，正好就走进我们的镜头里。"

Just listed this phone, he's hard-line opponents of digital camera, but it can automatically rotate, even more surprising is that it has a ccd 1000-megapixel camera.

刚上市的这款手机，他的强硬对手是数码相机，但是它可以自动旋转，更让人惊讶的是它拥有ccd 1000万像素的摄像头。

A set of linear constraints on the camera intrinsic parameters is then derived by means of homography matrix.The camera is then linely calibrated.

这种定标方法最大的缺点就是：需要一高精度的标定参照物，并且在很多实际应用中难以实现。

In the system, a 2D motion model is established on the image plane of the static camera to predict the position of the object by Kalman filter, then by using homography relation, the predicted position of object can be obtained on the image plane of the dynamic camera.

系统在静态摄像机的图像平面上建立目标的2D运动模型，采用卡尔曼滤波实现目标位置的预测，由单应性关系求出动态摄像机图像平面上对应目标的预测位置，然后计算摄像机动态平台的旋转角度，实现对动态平台的伺服控制。

A new algorithm is presented to determine infinite homography matrix and camera intrinsic matrix parameters under one camera motion set from the matched-point sets on two orthogonal planes.

摘要论述由位于正交平面上的特征点对集合复原无穷远单应性矩阵和摄像机内参数的新算法。

In IBR (image-based rendering) application, we introduce homotopy mapping into view interpolation based on uncalibrated images, and present three forms of perspective homotopic transform according to different conditions.①The linear interpolation technique presented only preserves perspective geometry, but the intrinsic and extrinsic parameters of camera are changed. For the uncalibrated images, its application is restricted.②The view interpolation presented for rotational uncalibrated images can preserve both perspective geometry and the intrinsic parameters of camera, and the view position can be controlled. At meanwhile, the image registration method and panoramic images synthetic method is presented.

3在基于图象的绘制技术方面，将同伦变换引入视图插补中，针对未标定图象序列，并根据以下三种情况给出相应的透视同伦变换，①只保证符合透视关系，而摄象机内外参数均已改变的线性插补技术，对于标定图象序列，这种插补技术是非约束的，而对于未标定图象序列则只适合于某些特殊场景；②旋转图象序列的视图插补技术，同时给出了旋转图象序列的整合及全景图生成方法；③通过对非约束图象的预校正，完成平移情况下的视点插补。

Close to the hyperfocal distance, the small-sensor camera has a much more than 1.6x the DOF of a full-frame camera.

如果在全幅机和小幅机上使用相同镜头，为了达到相同的视野而在不同的距离拍摄，小幅机比全幅机多1.6倍的景深。

The production used a Toshiba three-chip ice-cube camera and a Sony lipstick camera, according to the DP."Those were recording to a Sony DV clamshell," says Ward."But that raised the question: If we use those cameras, can we go all the way out to 35mm for the final print?"

马上我们意识到必须用小型微型镜头来代替，"图像由他们传送到一个Sony DV盒带中"沃德说，"接着问题出来了：如果我们使用哪些摄像机，最后能够在35毫米规格中使用呢？"

The measurement is simulated by ""regular icosahedron "" method, utilizing the direct current moment electric motor and the photoelectrical axis angle encoder, the rotation of the shot carrier and the CCD camera is completed, and can orientation the rotating angle, so that the system can make the CCD camera to measure the square diagraph in 16 independent projections.

该系统的研制是利用"正二十面体"方法进行模拟，直流力矩电动机和光电轴角编码器配合使用，完成载物台和CCD相机的旋转运动和角度定位，使CCD相机能够实现对十六个独立方向上的投影测量。

For our 2D drawing, we don't need to move the camera, and we don't want to move the world for now, so we'll use an identity matrix, which basically sets the camera and world in a default position.

为了我们的2D绘制，我们不需要移动摄像机，也不用想移动世界，所以我们将使用一个单位矩阵，将摄像机和世界放置在缺省的位置。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
