It learns spatial features from raw 3D points without requiring voxelization or image projections. This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/pointnet) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary). Qualcomm AI Hub Models uses [Qualcomm AI Hub Workbench](https://workbench.aihub.qualcomm.com) to compile, profile, and evaluate this model. [Sign up](https://myaccount.qualcomm.com/signup) to run these models on a hosted Qualcomm® device. ## Getting Started There are two ways to deploy this model on your device: ### Option 1: Download Pre-Exported Models Below are pre-exported model assets ready for deployment. | Runtime | Precision | Chipset | SDK Versions | Download | |---|---|---|---|---| | ONNX | float | Universal | QAIRT 2.42, ONNX Runtime 1.24.3 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/pointnet/releases/v0.50.2/pointnet-onnx-float.zip) | QNN_DLC | float | Universal | QAIRT 2.43 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/pointnet/releases/v0.50.2/pointnet-qnn_dlc-float.zip) | TFLITE | float | Universal | QAIRT 2.43, TFLite 2.19.1 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/pointnet/releases/v0.50.2/pointnet-tflite-float.zip) For more device-specific assets and performance metrics, visit **[PointNet on Qualcomm® AI Hub](https://aihub.qualcomm.com/models/pointnet)**. ### Option 2: Export with Custom Configurations Use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/pointnet) Python library to compile and export the model with your own: - Custom weights (e.g., fine-tuned checkpoints) - Custom input shapes - Target device and runtime configurations This option is ideal if you need to customize the model beyond the default configuration provided here. See our repository for [PointNet on GitHub](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/pointnet) for usage instructions. ## Model Details **Model Type:** Model_use_case.semantic_segmentation **Model Stats:** - Model checkpoint: save - Input resolution: 1x3x1024 - Model size: 13.2 MB ## Performance Summary | Model | Runtime | Precision | Chipset | Inference Time (ms) | Peak Memory Range (MB) | Primary Compute Unit |---|---|---|---|---|---|--- | PointNet | ONNX | float | Snapdragon® 8 Elite Gen 5 Mobile | 0.319 ms | 0 - 29 MB | NPU | PointNet | ONNX | float | Snapdragon® X2 Elite | 0.314 ms | 7 - 7 MB | NPU | PointNet | ONNX | float | Snapdragon® X Elite | 0.784 ms | 7 - 7 MB | NPU | PointNet | ONNX | float | Snapdragon® 8 Gen 3 Mobile | 0.405 ms | 0 - 42 MB | NPU | PointNet | ONNX | float | Qualcomm® QCS8550 (Proxy) | 0.648 ms | 0 - 8 MB | NPU | PointNet | ONNX | float | Qualcomm® QCS9075 | 0.826 ms | 0 - 3 MB | NPU | PointNet | ONNX | float | Snapdragon® 8 Elite For Galaxy Mobile | 0.435 ms | 0 - 25 MB | NPU | PointNet | QNN_DLC | float | Snapdragon® 8 Elite Gen 5 Mobile | 0.32 ms | 0 - 30 MB | NPU | PointNet | QNN_DLC | float | Snapdragon® X2 Elite | 0.426 ms | 1 - 1 MB | NPU | PointNet | QNN_DLC | float | Snapdragon® X Elite | 0.801 ms | 0 - 0 MB | NPU | PointNet | QNN_DLC | float | Snapdragon® 8 Gen 3 Mobile | 0.414 ms | 0 - 43 MB | NPU | PointNet | QNN_DLC | float | Qualcomm® QCS8275 (Proxy) | 1.857 ms | 0 - 27 MB | NPU | PointNet | QNN_DLC | float | Qualcomm® QCS8550 (Proxy) | 0.663 ms | 0 - 6 MB | NPU | PointNet | QNN_DLC | float | Qualcomm® QCS9075 | 0.798 ms | 2 - 4 MB | NPU | PointNet | QNN_DLC | float | Qualcomm® QCS8450 (Proxy) | 0.867 ms | 0 - 44 MB | NPU | PointNet | QNN_DLC | float | Snapdragon® 8 Elite For Galaxy Mobile | 0.477 ms | 0 - 26 MB | NPU | PointNet | TFLITE | float | Snapdragon® 8 Elite Gen 5 Mobile | 0.315 ms | 0 - 30 MB | NPU | PointNet | TFLITE | float | Snapdragon® 8 Gen 3 Mobile | 0.412 ms | 0 - 44 MB | NPU | PointNet | TFLITE | float | Qualcomm® QCS8275 (Proxy) | 1.9 ms | 0 - 28 MB | NPU | PointNet | TFLITE | float | Qualcomm® QCS8550 (Proxy) | 0.663 ms | 0 - 2 MB | NPU | PointNet | TFLITE | float | Qualcomm® QCS9075 | 0.804 ms | 0 - 9 MB | NPU | PointNet | TFLITE | float | Qualcomm® QCS8450 (Proxy) | 0.863 ms | 0 - 45 MB | NPU | PointNet | TFLITE | float | Snapdragon® 8 Elite For Galaxy Mobile | 0.485 ms | 0 - 27 MB | NPU ## License * The license for the original implementation of PointNet can be found [here](https://github.com/nikitakaraevv/pointnet/blob/master/LICENSE). ## Community * Join [our AI Hub Slack community](https://aihub.qualcomm.com/community/slack) to collaborate, post questions and learn more about on-device AI. * For questions or feedback please [reach out to us](mailto:ai-hub-support@qti.qualcomm.com).
