OpenCV Zoo and Benchmark

A zoo for models tuned for OpenCV DNN with benchmarks on different platforms.

Guidelines:

• Install latest opencv-python:

  python3 -m pip install opencv-python
  # Or upgrade to latest version
  python3 -m pip install --upgrade opencv-python
  

• Clone this repo to download all models and demo scripts:

  # Install git-lfs from https://git-lfs.github.com/
  git clone https://github.com/opencv/opencv_zoo && cd opencv_zoo
  git lfs install
  git lfs pull
  

• To run benchmarks on your hardware settings, please refer to benchmark/README.

• MAIX-III AXera-Pi: Axera AX620A SoC with a quad-core ARM Cortex-A7 CPU and a 3.6 TOPS @ int8 NPU.
• Toybrick RV1126: Rockchip RV1126 SoC with a quard-core ARM Cortex-A7 CPU and a 2.0 TOPs NPU.

RISC-V:

• StarFive VisionFive 2: StarFive JH7110 SoC with a RISC-V quad-core CPU, which can turbo up to 1.5GHz, and an GPU of model IMG BXE-4-32 MC1 from Imagination, which has a work freq up to 600MHz.
• Allwinner Nezha D1: Allwinner D1 SoC with a 1.0 GHz single-core RISC-V Xuantie C906 CPU with RVV 0.7.1 support. YuNet is tested for now. Visit here for more details.

Important Notes:

• The data under each column of hardware setups on the above table represents the elapsed time of an inference (preprocess, forward and postprocess).
• The time data is the mean of 10 runs after some warmup runs. Different metrics may be applied to some specific models.
• Batch size is 1 for all benchmark results.
• --- represents the model is not availble to run on the device.
• View benchmark/config for more details on benchmarking different models.
