What is a Monocular Depth Cue?
What do you understand about monocular depth cues? These cues are the information in the eye’s retinal images, which provide information about distance and depth.
Such cues work in both eyes, but you will not feel any difference when using these monocular cues with your one eye.
You can see that you will not see any difference in your eyesight by closing your one eye and can differentiate the objects and depths’ distances, the same as you feel with both eyes.
Some people say that they get a better vision about their around when they see with one eye. Read the below content and discover more about monocular depth cues.
What are some common monocular cues?
Some common monocular cues help us to perceive the depth in our surrounding objects.
The relative size of an object
The first monocular cue that we are explaining is the relative size of an object. It acts as a monocular cue for depth perception.
One simple explanation for you is that when we see two roughly objects of the same size, then the larger object will look close to us than the small object.
It is applied both on two-dimensional images and three-dimensional scenes. When two objects are placed on the table at the same distance, we feel that the object with a larger size is close to us than the smaller object.
Because the depth of the larger image becomes less from our eyes than the smaller object due to its larger size, so it looks us closer to our eye.
Position of the object relative to the horizon
When any of the positioned objects relative to the horizon can also serve as the monocular cue. The objects placed closer to the horizon will look at us as they are placed at more distance than the objects placed far from the horizon.
Amount of lighting and shading on objects
The amount of lighting and shading on the objects also presents the monocular cue. The objects placed in the light will see closer, while the objects placed in the dark places will appear far away from the observers.
Perception of the moving objects
The motion of the objects can also serve as the monocular cue for depth. When we move, the objects that come closer to us seem to zoom run faster and clearer than the objects at distances.
When we drive a bike, we feel that objects such as the sign boars near the roads move faster than the trees far from the roads.
Aerial perspective as a monocular depth cue
When we see the farther away objects seem hazy and blurred while we look at the horizon, the objects at a distance seem obscured by water vapor and dust. But the objects closer to us seem more distant than the real distant.
