Valentin Bolshakov

Computer Vision / Edge AI Engineer

I work on real-time computer vision, embedded inference, and perception systems, with a focus on taking algorithms from prototyping to resource-constrained hardware.

My main areas of interest are object detection and tracking, stereo vision, camera calibration, classical computer vision, and neural network deployment on edge devices.

Most of my commercial and production work is private or NDA-protected. The repositories below contain independent tools, experiments, and engineering projects related to the areas I work in.

Selected public projects

YOLO → RKNN Converter Toolkit for deploying YOLO-family detectors on Rockchip NPUs. Covers ONNX graph modification, INT8 post-training quantization, RKNN conversion, and reference inference.

Stereo Camera Calibration Configurable OpenCV pipeline for intrinsic and stereo calibration, reprojection-error analysis, outlier filtering, and estimation of relative camera pose.

BrightSpotDetector Lightweight C++ / OpenCV detector for bright targets in grayscale, thermal, and IR imagery, with configurable ROI and detection parameters.

Electronics Workshop Personal hardware projects covering the complete prototyping cycle from circuit design and firmware to assembly and enclosure.

  1. yolo-rknn-converter yolo-rknn-converter Public

    Extensible toolkit for converting YOLO-family detectors to RKNN format. Includes quantization dataset preparation and a reference inference pipeline with raw tensor output.

    Python 2

  2. stereo_calib_py stereo_calib_py Public

    Two-stage calibration pipeline for stereo camera systems: intrinsic calibration (per-camera parameters) followed by extrinsic calibration (relative pose between cameras).

    Python 2

  3. BrightSpotDetector BrightSpotDetector Public

    A C++ implementation of a bright spot detector.

    C++ 1

  4. ElectronicsWorkshop ElectronicsWorkshop Public

    My engineering workshop: a collection of homemade electronic devices with a full design cycle — from the idea to the final case. All projects are designed, assembled and tested personally.
