1 Group S2 Summary Rich Wrigley

2 We needed to… Learn how to used the ‘eyeballs’ Learn how to use ‘Paintshop Pro’ Create Anaglyphs Solid angle theory Measure disparity of images to choose best camera separation Determine best separation etc. for a lander Image a crater (If we had time)

3 Creating Anaglyphs - (and going insane in the process)  First attempts were fairly ‘low tech’. Mainly just test driving the cameras.  Later on measured disparity and used solid angle theory to refine the process, and choose the best camera separation as well as size and distance of object.  Making anaglyphs on PaintshopPro…

4 PainshopPro Take two images of one object. Make the two images semitransparent. Tint one red and one blue. Merge them.

5 Disparity Take two images using the eyeballs. Measure the distance between a fixed point of the images. We varied the eyeball separation, and the distance of the fixed point.

6 Some results…

7 … because we’re nerds and like graphs.

8 Imaging the crater. Worked with a Planetary Cratering GReP. Using data obtained, used the best camera separation (18cm) and object distance (75cm) to image crater. Created anaglyph as done previously.

9

10 Best cameras for a lander Decided to get a good anaglyph eyeball separation needed to be ~ separation of eyeballs This would allow us to image objects that were close up (1-3m) Eyeball distance also good size to easily fit on lander. Larger objects and distances need larger eyeball separation. Therefore our lander’s stereo camera good for imaging rocks and close up objects, but not mountains etc.
