What are the 3d coordinates of the point in the world that produce these two image points? so let's draw an equation for a line for a left image.
00:10
Our left image is located at 4, 1, 1, and so that's equal to our x, y, z plus some time x, y, z.
00:21
And so we get x plus tx, y plus time times y, z plus tz.
00:29
Now we can rewrite x equal to 4 over 1 plus t, y is equal to 1 over 1 plus t, and z is equal to 1 over 1 plus t.
00:41
We can do the same thing for a right image which is located at 6, 1, 1.
00:45
And so we write 6, 1, 1 is equal to x, y, z plus t times x minus 10, y, z equal to x plus tx minus 10t, y plus ty, z plus tz.
01:05
Now we have another parameter here.
01:08
X is equal to 6 plus 10t divided by 1 plus t, y is equal to 4 over 1 plus t...
