A very good question Box Brownie and something that is well worth adding to the list of things that could increase the level of accuracy with any measurements as the index of refraction would be slightly different to air I should imagine. ianp5a, curiosity does have some stereoscopic images but...

Here is a link about focusing on the 100mm camera, it mentions at the bottom of this page that distances we're calculated using a combination of curiosity's images and the high res satellite image data which may be the only way to get accurate measurements but proximity measurements will...

Box Brownie, many thanks for your assistance along with the others on this post as it has been a great help. A number of years ago I downloaded a lens program and modeled a pair of binoculars but then I new the curvature of all the lenses which made it much easier as I actually created all the...

Thanks for that feedback StewartR, just one last question and then I can set about trying some of these methods out. I found another article that says there is an autofocus mechanism within the lens set that will focus from 2.1 metres to infinity and I am assuming that this will just increase...

Thanks StewartR, as these images are cropped to a square shape, will I need to calculate the vertical FOV or is it still classed as the same in other words has the FOV already taken into account the cropping.

Here is a link to the data sheet or specs. http://www.datasheetarchive.com/KAI-2020-datasheet.html (Edited) here is a better version of the spec sheet. http://www.stargazing.net/david/QSI/KAI-2020LongSpec.pdf

Okay, I have found the ccd type here. Now off to find the ccd spec. Although they use different optics, all four main images on the Curiosity rover use the same KAI-2020CM CCD imager, originally supplied by Kodak...

I have just found this information from Box Brownie's post but as you say will probably have to get the ccd type to find dot pitch or pixel spacings and ascertain the actual size of the sensor. the Mastcams are based around 1,600 x 1,200 pixel CCD sensors, but both Mastcams have a square crop...

Thanks for the feedback lads, it's not an easy one as very few known lengths or distances within the Mars Curiosity images only snippets where some of the parts of the rover are in view but I have an idea that some of the aerial satellite images of some of the area's that have mountain peaks...

Problem solved it has just turned up in the Talk Photography Forum.:)

Just posted my first post about 30-40 minutes ago and received an alert saying the post had been moved to another forum but does not say where, any ideas as I have obviously posted to the wrong section. Here was what my alert said. Your thread Overlaying a grid on a photograph was moved to a...

Hello all, I am new to the forum and a novice really with photography but wonder if anyone can help me out. I am in a Mars anomaly research group that is analyzing structures and other objects on the NASA Mars rover Curiosity images, and to cut a long story short the images do not have any...
