Seen in another Jeypore-Dehing camera-trap picture, the leopard cat is a diminutive and distant relative of the better-known spotted predator from which it takes its name.

这张照片的主角是豹猫。 豹是最为人们熟悉的斑点皮纹食肉动物，因为体形偏小，又是豹的远亲，豹猫的名字就由此而来。

This isn't a liable solution, because when the billboards turn to follow the camera, their Angle relative to the light source will change, and so will their brightness.

这不是一个主观的解决办法，因为当粒子块朝向摄像机时，他们与光源的角度会改变，他们的亮度也会随之而变。

Because the calibration method directly optimizes the camera rotation angles relative to the world coordinate system, it ensures the orthonormal constraints as well as the precise solutions.

该标定方案直接优化摄像机相对于世界坐标系的旋转角度，因此能够在获得精确解的同时，保证旋转矩阵的正交约束条件。

We're looking at a revamped but still tiny CX sensor, this time with the resolution bumped up to 14 megapixels (instead of 10) -- a move that likely won't do much for the camera's overall image quality or low light performance relative to APS-C or Micro Four Thirds shooters.

Pixim's innovation is to give each pixel its own analog-to-digital converter so that photons are continuously converted to ones and zeros and the camera's microprocessor can tell exactly how fast each pixel is filling up relative to the other pixels.
