Access Mars lets you explore a 3D replica of the Martian surface, exactly as it was recorded by the Curiosity rover. As Curiosity has travelled across Mars, it’s taken digital photographs with two stereoscopic camera systems. By combining and analyzing these photographs, scientists at NASA JPL have created a 3D model used to study Mars and plan future experiments. For the first time, this same 3D model is now available here for anyone to explore in their browser using WebVR.
Image mosaics are captured with the left and right Navcam and Mastcam.
The two mosaics are then combined together to create a stereo match.
Using the data from the stereo match scientists are able to extract 3D mapping data.
Using metadata from the time, location, and direction the images were taken, scientists can tile the terrain data into a composite piece of terrain.
