Definition of Parallax Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06 Definition of Parallax Parallax is the apparent difference in an object’s position, as observed from two different points of view.

Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06 Parallax can easily be observed with the eyes, a natural dual sensor system. Center of Retina Images of Object

Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06 Calculation of Parallax - the focal length of system n n - the distortion coefficient of system n. Mn - the optical magnification of system n - the number of pixels between the pixel the image occupies and the center of the sensor - the pixel pitch of sensor n

Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06   - distance on display of image from sensor n - the ratio of the display pixel count and the pixel count of sensor n - the pixel pitch of the display OP – observed parallax

Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06 Parallax Versus Range

Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06 Parallax Versus Range Little Noticeable Parallax Very Noticeable For sensors in parallel, parallax decreases with range.

Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06 Parallax Versus Angular Separation

Sean Moore Quantification of Parallax In Dual Sensor Systems Dec 06 Conclusion The capabilities of a sensor can be enhanced through dual-waveband technology. Parallax is an issue that will need to be dealt with in these systems. Understanding parallax is a necessary step towards dealing with it.
