### How it works

The camera captures depth data. Ground calibration establishes the spatial reference, and each slot is defined by its 3D bounds. The algorithm filters the scene, detects cargo within each slot, and returns occupancy and the enabled measurements.

<div align="center"><img src="https://742486550-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FmoqeeXLb686zPPeOsDq3%2Fuploads%2Fgit-blob-92c932a26f38331469b8cc9110a9ad0aace796c3%2Fstocksync-detection-flow.png?alt=media" alt="Empty and occupied slots, ground reference, depth capture, detection, and outputs" width="860"></div>

### Outputs and capabilities

| Output or capability          | Purpose                                                                            |
| ----------------------------- | ---------------------------------------------------------------------------------- |
| Empty / occupied              | Indicate whether valid cargo is detected within the configured slot.               |
| Placement quality             | When enabled, distinguish normal, misaligned, and out-of-bounds placement.         |
| Dimensions                    | Report the object's bounding dimensions when measurement is enabled.               |
| Coverage                      | Report the portion of the slot footprint occupied by cargo.                        |
| Multiple slots                | Configure multiple slots per camera; cameras detect independently.                 |
| AW3 configuration and results | Calibrate, configure slots, inspect results, and forward data to business systems. |

The white paper specifies S10 Pro as the standard camera. Confirm the device platform against the **RK3588** package before installation. Validate occupancy and dimensional performance separately at the actual mounting height, lighting, and cargo conditions. Occlusion and very dark surfaces can affect detection; highly reflective objects are outside the documented operating conditions.
