Tong Guo To annotate the XYZ coordinates of an object relative to a camera on a 2D image, you first need to understand the relationship between 3D space and 2D projections. Imagine you are taking a photo of a cup placed on a table. The cup exists in 3D space with height, width, and depth, but your camera captures it as a flat 2D image. The process of finding and marking its coordinates involves the following steps:

This process is widely used in robotics, augmented reality, and autonomous vehicles to understand object positions in the real world.

In robotics, if a robotic arm needs to pick up an apple, it must know the apple’s position in 3D space. The camera captures the image, calculates the XYZ coordinates, and feeds this data to the arm, ensuring it moves accurately to grab the apple without missing.
