Pose estimation STM32 model zoo

January 22, 2026 ยท View on GitHub

Directory Components:

  • datasets placeholder for the pose estimation datasets.
  • docs contains all readmes and documentation specific to the pose estimations use case.
  • src contains tools to evaluate, benchmark, quantize and deploy your model on your STM32 target.

Quick & easy examples:

The operation_mode top-level attribute specifies the operations or the service you want to execute. This may be single operation or a set of chained operations.

You can refer to readme links below that provide typical examples of operation modes, and tutorials on specific services:

All .yaml configuration examples are located in config_file_examples folder.

The different values of the operation_mode attribute and the corresponding operations are described in the table below. In the names of the chain modes, 'e' stands for evaluation, 'q' for quantization, 'b' for benchmark and 'd' for deployment on an STM32 board.

operation_mode attributeOperations
trainingTrain a model from the variety of heatmaps single pose estimation models in the model zoo (BYOD) or your own model with the same model type (BYOM)
evaluationEvaluate the accuracy of a float or quantized model on a test or validation dataset
quantizationQuantize a float model
predictionPredict the classes some images belong to using a float or quantized model
benchmarkingBenchmark a float or quantized model on an STM32 board
deploymentDeploy a model on an STM32 board
chain_tqebSequentially: training, quantization of trained model, evaluation of quantized model, benchmarking of quantized model
chain_tqeSequentially: training, quantization of trained model, evaluation of quantized model
chain_eqeSequentially: evaluation of a float model, quantization, evaluation of the quantized model
chain_qbSequentially: quantization of a float model, benchmarking of quantized model
chain_eqebSequentially: evaluation of a float model, quantization, evaluation of quantized model, benchmarking of quantized model
chain_qdSequentially: quantization of a float model, deployment of quantized model

The model_type attributes currently supported for the pose estimation are:

  • spe: These are single pose estimation models that outputs directly the keypoints positions and confidences.
  • hand_spe: These are single hand landmarks estimation models that outputs directly the keypoints positions and confidences of the hand pose.
  • head_spe: These are single head landmarks estimation models that outputs directly the keypoints positions and confidences of the head pose.
  • heatmaps_spe: These are single pose estimation models that outputs heatmaps that we must post-process in order to get the keypoints positions and confidences.
  • yolo_mpe : These are the YOLO (You Only Look Once) multiple pose estimation models from Ultralytics based on the well known Yolov8 that outputs the same tensor as in object detection but with the addition of a set of keypoints for each bbox.

You don't know where to start? You feel lost?

Don't forget to follow our tuto below for a quick ramp up :

Remember that minimalistic yaml files are available here to play with specific services, and that all pre-trained models in the STM32 model zoo are provided with their configuration .yaml file used to generate them. These are very good starting points to start playing with!
