DISTANCE ESTIMATION AND DEPTH PERCEPTION Flashcards
NVG DISTANCE AND DEPTH PERCEPTION
NVGs distort depth perception and distance estimation. The quality of depth perception in a given situation depends on factors including available light, type and quality of NVGs, degree of contrast in the FOV, and user experience. The aircrew must often rely on the monocular cues
NVS DISTANCE AND DEPTH PERCEPTION
The FLIR system greatly affects depth perception and distance estimation. To help overcome the loss of peripheral vision cues and the two-dimensional image, flight information is symbolically superimposed on the FLIR image. An aviator must rely on flight symbology and monocular cues for accurate depth perception and distance estimation.
MONOCULAR CUES
- Geometric Perspective
- Retinal Image Size - Aerial Perspective
- Motion Parallax
GEOMETRIC PERSPECTIVE
- Linear Perspective
- Apparent Foreshortening
- Vertical Position In The Field
RETINAL IMAGE SIZE
- Known Size Of Object
- Increasing Decreasing Size
- Terrestrial Association
- Overlaping Contours/Interposition Of Objects
AERIAL PERSPECTIVE
Fading Colors And Shades
Loss Of Detail Or Texture
Position Of Light Source And Direction of Shadow
