| 2015-05-21 01:41:36 -0500 | answered a question | Does anyone know the focal length(mm) of RGB camera? I don't know whether I'm right or not. As the focal length in pixels is 525(default) and the pixel size is 2.8 um, the focal length is 525*2.8 um = 0.147 cm. |
| 2015-05-20 21:10:11 -0500 | asked a question | Does anyone know the focal length(mm) of RGB camera? Image size is 640*480. I don't know whether I'm right or not. As the focal length in pixels is 525(default) and the pixel size is 2.8 um, then the focal length is 525*2.8 um = 0.147 cm, which is needed to use my robot model. I've used this parameter to implement conversion from image coordinate to camera coordinate. But it turns out a big error. |

| 2015-05-18 22:03:19 -0500 | answered a question | Who knows the pixel size of the image(640*480) of kinect RGB camera Problem resolved. Check on this site: http://zh.scribd.com/doc/86437713/kin... And you'll find: ...over 1.3 mm (0.051 in) per pixel I'm gonna try on this value. |
| 2015-05-18 20:31:54 -0500 | commented answer | Who knows the pixel size of the image(640*480) of kinect RGB camera Thx for your reply. 1, I'm gonna to check out the (Color CMOS) VNA38209015 chip. 2, Or my graduation project is due to be handed in... Aw~_~ |

| 2015-05-18 07:46:04 -0500 | asked a question | Who knows the pixel size of the image(640*480) of kinect RGB camera I know other cameras' parameters, which are often given. For example, CCD's is 80 pixel/mm. I've asked others, and maybe the pixel size should be calculated. If you've ever done this or knew something, hope to get your results or quotes. Thx in advance. |
