With the rapid globalization of supply chains and the scaling up of transportation and warehousing, automation has become an urgent need. Among all the key processes, palletizing and depalletizing stand at the very core of efficient and safe material handling.

1. What is Palletizing & Depalletizing?
While often referred to as a single process, “palletizing & depalletizing” actually consists of two distinct tasks:
- Palletizing: The process of stacking loose items into an organized, complete pallet.
- Depalletizing: The reverse—unloading items from a pallet into individual units.
Compared to palletizing, depalletizing is much more challenging. In real-world logistics operations, robots must deal with:
- Objects of various sizes and shapes,
- Severe occlusions,
- Misaligned or shifted goods,
- External lighting or reflective interference.
These challenges make depalletizing one of the toughest automation tasks in modern logistics.
2. Visual Solutions for Automated Palletizing & Depalletizing
The “eyes” of automation lie in its vision system. Several approaches are currently used:
2D Cameras
Effective in structured environments but limited in handling depth, occlusions, and irregular objects.
Stereo Vision
Simulates human eyes to perceive depth. While cost-efficient, its accuracy decreases in large-scale or long-distance scenes, and it is sensitive to lighting conditions.
Structured Light
Provides high precision for static and small-range applications. However, it struggles under outdoor lighting, reflective surfaces, or dynamic scenes.
3D ToF Cameras
Time-of-Flight (ToF) cameras measure distance using light pulses, delivering robust performance in complex environments. With strong anti-light interference, adaptability to dynamic scenes, and high accuracy for irregular objects, 3D ToF cameras have become the optimal choice for palletizing and depalletizing automation.
