What Causes Parallax Error and How Do You Avoid It?

Parallax error is primarily caused by viewing the object at an oblique angle with respect to the scale, which makes the object appear to be at a different position on the scale. Place the measurement device on its edge so it is level with the object being measured.

What Causes Parallax Error and How Do You Avoid It?

Parallax error is an optical illusion that occurs when an object is viewed from different angles. The illusion is created when the object appears to move from one side to the other, even though it is actually stationary.

Parallax error can occur when viewing an object from different positions, such as when looking at a book from different angles, or when looking at a 3D object from different angles.

The illusion occurs because our eyes see different images when we view an object from different angles. When we look at an object from the front, we see the object from one angle, and when we look at it from the side, we see it from a different angle.

Our brain interprets these different angles as different positions, and this is what creates the illusion of movement. There are a few different ways to avoid parallax error.

One way is to use a ruler or other straight edge to help align the object with your eye. Another way is to view the object from the same position each time, such as using a tripod to take a photo of the object.

Finally, you can use software to correct for parallax error, such as Adobe Photoshop. Parallax error can be a problem when taking photos or trying to
