The formula to calculate the Digital Height is:
OH=(SHR)×DFL
Where:
Digital height is the height of an object as it appears in a digital image. It is calculated using the physical properties of the camera sensor, the resolution of the image, the distance to the object, and the camera’s focal length. This measurement is useful in various applications such as photogrammetry, surveillance, and image analysis.
Let's assume the following values:
Using the formula:
OH=(244000)×1050=0.012 meters
The Object Height is 0.012 meters.
Let's assume the following values:
Using the formula:
OH=(366000)×2075=0.016 meters
The Object Height is 0.016 meters.
