James Cameron To Develop 3-D Camera For Mars Rover

Hugh Pickens writes "Computerworld reports that movie director James Cameron, of Avatar and Titanic fame, is working with Malin Space Science Systems Inc. to build an updated 3-D camera that will be installed on the Mars Science Laboratory rover Curiosity if completed in time, to be the machine's 'science-imaging workhorse,' says Michael Malin, who is working on the camera team. Malin delivered two cameras to be installed on the rover's main mast; however NASA has provided Malin with funding to work with Cameron to build alternatives to these two cameras. 'The fixed focal length [cameras] we just delivered will do almost all of the science we originally proposed. But they cannot provide a wide field of view with comparable eye stereo,' he says. 'With the zoom [cameras], we'll be able to take cinematic video sequences in 3-D on the surface of Mars.'"

Any Takers?

I'm taking bets on how long it takes NASA to discover blue aliens on Mars.

Why?

[dangitman]

I don't see why James Cameron's involvement is necessary. Stereoscopic imaging is pretty simple technology, and it's not like James Cameron invented it. What's so hard about turning a fixed-focal-length stereo camera into one that has zoom lenses? And why would you employ a film director, rather than an optical engineer to do it?

For the publicity. NASA is in serious need of some.

I don't know the level of detail that he was involved in, but Cameron did have a hand in developing the camera and he's used it in several of his movies (including Avatar).

How much actual technical help was he? No idea, but it is called the Pace-Cameron Fusion Camera System. It must be pretty good as well considering both the amazing job it did for Avatar and the fact that the technology is going to be used in other films as well.

And, as others mentioned, dropping his name is good for publicity and is probably designed to give the public something to look forward to from the next rover.

Having worked on several stereo films (including Avatar) I can tell you that it isn't simple at all. Building something that takes stereo photos and developing an automated machine that can take effective photos with proper interocular and all that jazz are two very different things. You can hand a camera to an experienced photographer and then to your sister and get two VERY different photos. With your sister, you'd be lucky if she didn't chop off the head. With the photographer, besides setting all the settings correctly, he'd also find the most effective angle/lighting to take the photo at.

It's also worth mentioning that Jim has had a lot of experience not only behind the camera, but also with using machines to capture imagery in very hostile enviornments. (see Ghosts of the Abyss and Aliens of the Deep.)

Really it makes perfect sense why they'd want his input, it just helps to know more about who he is and how simple stereo photograph aint. ;)

Actually, Cameron did indeed study physics, and did a lot of engineering. As others have mentioned, he's most likely one of the best-connected people to the community of optical engineers who work on 3D images. He's already proven that he can co-design a pretty effective 3D camera.

And it's not like NASA is putting him in charge of anything. He's being brought in as an adviser, probably on a pretty high level, and as far as I can tell, pro bono. I think that's pretty cool. I have no doubt that he will contribute two or three useful ideas based on his extensive experience. This also serves to promote the narrative of Cameron the technical wizard: Gear he helped design even went to Mars! It makes a great feel-good talking point for him when he's doing the interview circuit for his next movie.

I think if the Slashdot crowd really wanted technical examples, they'd ask questions instead of making statements. ;)

Photography is a strong blend of art and science. The expert photographer would understand that he is capturing a two dimensional image of a three dimensional object. He'd make sure the lighting is such that it gives proper cues to the brain about what its three dimensional form is. He'd attempt to capture the subject at the right angle that its silohuette reads, even making choices about what's behind it. He'd also compose the shot to land your eye onto the right part of the image. He'd also do things like make sure there isn't a bright light-source behind the subject preventing the camera from exposing them properly. This is only a small portion of what a professional photographer would do.

Stereo photography is all that and then it's compounded by having a second camera in the mix. On Avatar a number of things had to be taken into consideration. Take an environment like the Ops Center. You've got a lot of shiny hard edged things, many right up near the camera, and a good deal of overlap. Shiny, in particular, is a problem. With the seperation between the cameras the specularity or reflectivity of the metal can cause one eye to see something drastically different from the other. Sometimes that's fixed by a guy on the set, sometimes it's fixed by re-composing the shot. How far apart should the cameras be? That depends on what you want to show the audience. It's not as simple as "Make it the width of a human!" because our eyes don't zoom. When you zoom in the seperation is exaggerated so you have to adjust the width. When you're transitioning from one shot to another you have to be mindful of how much you're asking the audience to change their focus. Etc etc etc.

What it all boils down to is that there is no simple set of rules to shoot streographically. This worries me as I imagine the whole reason they'd do this is to make the stereo functions on the machine as automatic as possible. They only way they're going to make something usable a suitable percent of the time is to have a good idea of the sort of scenarios it would encounter and how it could best deal with them. That's where having somebody who's been behind the lens of a stereo camera for many many hours comes in handy. And that is why somebody like Jim would be ideal to have on hand.

My sister's an excellent photographer, you insensitive clod!

James Cameron -> The Terminator -> Arnold Swarchenegger -> Total Recall -> Get Your Ass to Mars!!!

No need for two cameras

[jms]

This will satisfy the burning need for three dimensional movies of stationary martian rocks.

Re:Sigh...

[MichaelSmith]

What bothers me about this, though, is that this science project has to pander to the public with eye-candy. Because we can't sell them on the science. I think this says something about our national lack of education, and something about the public having become a massively parallel knee-jerk driven by the lies fed to them daily on Fox TV and the trash TV that is more important to them than mankind's future.

No Bruce its the same all around the world. I don't think it is education as such. I am sure there are plenty of highly educated managers who would not care about the science and perhaps be inspired by a good picture in passing.

Immersion is a good way of catching people's attention. Cameron did that with Avatar and found new viewers for a simple action+SF story. Maybe he can do the same with Mars. Maybe someone can sell monitors just for viewing the latest from Mars in 3D. I don't think data on air temperature or organics in the soil will ever do it for the majority.

It's obvious why NASA needs him

[OrwellianLurker]

Who else is going to be able to fake the Mars landing?

Does anyone bother to read the nice words?

[Anonymous Coward]

Several people got modded up for questioning why Cameron was "hired" or "designing" the rig. He's not been hired and no one said he's designing anything. He's promoting the idea with NASA to help get people more excited about space. The Mars rover shots did more to get people excited about space than anything since the Moon landing. He's also going to be advising the team but that's legitimate given how much experience he has with 3D camera rigs, it goes back to Terminator 3D, I worked on it and he does know the subject. He also knows the best people in the field for helping them design the rig and software so he can make contacts for them. It's a growing field but 10 years ago the experts were on a very short list. I worked on several 3D productions and you always used to see a lot of the same faces. He's offering free help and he's better informed than most people here seem to give him credit for. Avatar has the best 3D ever and his pushing to make it the best was the reason why. Focusing strictly on hard science is a great way to drive people away. Also 3D images have technical value. Ever try to drive a car with one eye closed? In the future when rovers travel faster and further stereo vision systems will become more important. Now is a good time to develop the technology. Good on Jim for diving in. NASA needs all the help it can get if they are to have any hope of hanging onto their budget as money tightens up.

Re:Does anyone bother to read the nice words?

[Required Snark]

I have also worked in the film business and worked on 3D projects, and it is still an art, not a science. There are a lot of trade-offs involved, and experience is a big factor in making the right choices.

Besides this, Cameron has already worked with scientists. Between Titanic and Avatar he got involved in other deep sea filming projects. He's been with oceanographers and worked with remotely operated vehicles. Kind of like a rover on Mars.

The way he makes films uses 'pre-visualization', where virtual environments are built before the film is shot, allowing many problems to be solved before being on the set. This is what they do when planning spacecraft operations. This is why there are all those flyby simulations that they show before the actual data comes back. In addition, the current Mars rover planning uses a virtual environment for generating path planning before the commands are sent to the real rover. Just like pre-viz in movies.

I would say that Cameron is a real asset for NASA. It's not like he is inserting himself where he is not wanted. I think he can make a positive contribution.

Negative

[Silvrmane]

The negative comments on Slashdot are really getting depressing to read. From Cameron's biography at IMDB:
James Cameron was born in Kapuskasing, Ontario, Canada, on August 16, 1954. He moved to the USA in 1971. The son of an engineer, he majored in physics at California State University.
So yeah, I think he can do trigonometry. He might actually be smarter than you. Give the guy a break.

Halo effect

[Hognoxious]

I heard he grinds the lenses himself. By hand. He also wrote an optimized implementation of MLT over dinner one night. In perl.
