Why are depth cameras common in indoor robot perception?

Asked on Oct 31, 2025

Answer

Depth cameras are prevalent in indoor robot perception due to their ability to provide detailed 3D information about the environment, which is crucial for navigation, obstacle avoidance, and interaction with objects. They offer real-time depth data that enhances the robot's understanding of its surroundings, enabling more accurate mapping and localization.

Example Concept: Depth cameras, such as stereo cameras or structured light sensors, capture 3D data by measuring the distance to surfaces within the camera's field of view. This information is used in Simultaneous Localization and Mapping (SLAM) algorithms to create a 3D map of the environment, allowing robots to navigate complex indoor spaces with precision.

Additional Comment:

Depth cameras are often used in conjunction with other sensors like IMUs and LIDAR for comprehensive perception.
They are particularly useful in environments with varying lighting conditions where traditional cameras may struggle.
Depth data can be used to enhance object recognition and manipulation tasks in robotics.
