In the field of logistics sorting, single item separation is a crucial step before automated sorting.
Piles of packages need to be separated one by one before entering the automated sorting line to ensure efficient processing.
However, in traditional warehouses, package separation mostly relies on manual labor, which not only consumes a large amount of manpower but also has low efficiency.
To improve the speed and efficiency of package separation, many companies have started to combine vision systems with conveyor belts to develop package recognition and single item separation systems.

Single Item Separation System Based on RGB-D ToF Camera
Goermicro Vzense has accumulated a wealth of successful cases in this field.
By integrating Vzense RGB-D ToF cameras and combining them with target detection algorithms, its partners have launched package recognition and single item separation systems for logistics sorting.
The system mainly consists of a scattering conveyor belt, a separation conveyor belt, and a 3D ToF depth camera.
Through the precise coordination of machine vision and the speed of the conveyor belt, the system can make piles of packages pull apart from each other before entering the automated sorting line, achieving orderly processing.
Whether it is a large or small package, it can be intelligently “queued” and separated, thus preparing for the next link in automated logistics.
According to incomplete statistics, the separation success rate of using this single item separation system is as high as 98%, with a workload of up to 4000 pieces per hour, equivalent to replacing 3-4 manual workers. This not only significantly improves the production efficiency of the logistics industry but also greatly reduces labor costs, bringing significant economic benefits.
Vzense RGB-D ToF Camera Solves Industry Pain Points
In the logistics sorting scenario, traditional two-dimensional color cameras can only capture the two-dimensional image information of the package, lacking depth distance data, which leads to low package recognition accuracy and easy misjudgment of the package status.
Some 3D cameras have problems such as low frame rate and motion blur, which cannot meet the needs of high-speed moving express packages.
In addition, some 3D cameras have a small field of view, requiring multiple cameras to be spliced to cover the complete field of view, increasing the complexity and cost of the system. The high price of 3D cameras is also an important factor that hinders their large-scale promotion in logistics sorting scenarios.
Advantages of Vzense RGB-D ToF Camera
The Vzense RGB-D ToF camera has the following significant advantages:
High Frame Rate: Up to 30fps, it can accurately capture high-speed moving packages, ensuring the stable operation of the system in dynamic scenarios.
High Cost Performance: Reasonable price, suitable for large-scale batch applications in logistics sorting scenarios, effectively reducing the overall cost.
Synchronous Capture of Two-Dimensional Depth and Information: It simultaneously obtains the two-dimensional color image and depth distance data of the package, which can accurately distinguish the position and status of the package, greatly improving the recognition accuracy.
Customization Ability: It can be customized in batches according to the needs of customers with edge computing power, further improving sorting efficiency and reducing solution costs.
Scene Display
Here is a comparison display of the RGB effect map and the Depth effect map:
RGB Picture: Only shows the two-dimensional color appearance of the package, lacks depth information, and cannot accurately judge the three-dimensional position and status of the package.
Depth Piture: Clearly presents the depth information of the package, which can accurately identify the outline, distance, and mutual position relationship of the package, providing key data support for single item separation.
With the help of Vzense RGB-D ToF cameras, single item separation in the logistics sorting field has become more efficient and intelligent.
Vzense will also be attending ProMat 2025, one of the biggest logistics shows worldwide. We welcome you to visit us there and see our innovative smart logistics solutions in action.
