Check out Don Mitchell's Venera stuff. It is by far the best I have seen (although I have seen a bit more than is on this site). His work recreating the raw images from the original data is far better than other sources available. Plus, he has lots of neat info on the other Veneras. -------------------- |

Here is a perspective drawing I made in support of the rectified airbrush view referenced earlier. I also made vertical projections and side views including the spacecraft, all plotted by hand. I abandoned the scenery mapping work because the airbrush required constant tweaking while performing at it's fine detail limit. I will redo such work digitally one of these days.

QUOTE (tedstryk @ Jun 2 2005, 04:34 AM) Nice work! I does make sense to orient the images that way. My best atempt in correcting this images is something like this: ![]() It makes sense to look at the Venera image strip as 2 separate images going from a point in the ground in front of the lander up to the horizon. Don Davis diagram of the camera's location really helps in figuring this out! The the images can be corrected for the odd scan angle and presented in more natural side view perspectives ;-) -------------------- _______________________

QUOTE (GregM @ Jun 3 2005, 02:51 AM) I think you just may have figured it out! Excellent work! If the Soviets in the 70' and 80's had figured out how reproject and rectify their own Venera images in the excellent ways seen in this forum, they would have scored a much bigger propaganda coup than what they did! Their loss then - our gain now! Actually, there are some rectified versions floating around...the problem is that all that remain of those are paper copies, which don't work well for enhancement. 4th rock - excellent job with rectifying the images. Be careful with the alignment - the tips of the pans slightly overlap, but the match isn't perfect due to camera parallax. If you look near where the images touch, you will notice the doublet features. Also, the curvature of the pans is backwards. Here are some Soviet reprojections: ![]() -------------------- |
