m1l0/opencv repository overview

⁠M1L0 OpenCV Docker image

Image of OpenCV built from source

There are 2 kinds of images: plain CPU images and GPU images

The GPU Images are built using nvidia CUDA images as source in a multistage build process.

⁠Supported builds

OpenCV versions:

• 4.5.5
• 4.6.0
• 4.7.0
• 4.8.0
• 4.9.0

All images are built using python 3.10.13, 3.11.6, 3.12.2 and Ubuntu 22.04

The GPU images are built to support the CUDA arch of 6.1, 7.0, 7.5, 8.0, 8.6

⁠Tagging and labels

CPU images are tagged in the following format:

<OPENCV VERSION>-<PYTHON VERSION>-<UBUNTU_VERSION>

e.g. 4.5.5-python3.10.9-ubuntu22.04 indicates that the image was compiled with 4.5.5 version of OpenCV with python version of 3.10.9 and Ubuntu version of 22.04

Likewise for GPU images, they are tagged in the following format:

<OPENCV VERSION>-<CUDA VERSION>-<CUDNN VERSION>-<PYTHON VERSION>-<UBUNTU VERSION>

e.g. 4.5.5-cuda11.8.0-cudnn8-python3.10.9-ubuntu22.04 indicates that the image was compiled with OpenCV 4.5.5, with CUDA version 11.8.0, CUDNN 8.0, python 3.10.9 and Ubuntu version 22.04

⁠Multi-stage builds

The OpenCV built artufacts are installed into /installed.

It can be used in multi-stage builds. For example to use the python bindings

FROM m1l0/opencv:4.5.5-python3.10.9-ubuntu22.04 as base

...

FROM ubuntu:latest
...

# copies the opencv libs from base image
COPY --from=base /installed /usr/local

# symlinks the shared lib into python site-packages
RUN ln -s /usr/local/lib/python3.6/site-packages/cv2/python-3.6/cv2.cpython-36m-x86_64-linux-gnu.so /usr/local/lib/python3.6/site-packages/cv2.so && \
    cd /usr/share/pkgconfig && \
    ln -s /usr/local/lib/pkgconfig/opencv4.pc opencv4.pc && \
    ldconfig

To use it with C++ bindings:

FROM m1l0/opencv:4.5.5-python3.10.9-ubuntu22.04 as base

...

FROM ubuntu:latest
...

# copies the opencv libs from base image
COPY --from=base /installed /usr/local

RUN cd /usr/share/pkgconfig && \
    ln -s /installed/lib/pkgconfig/opencv4.pc opencv4.pc && \
    echo "/installed/lib" >> /etc/ld.so.conf.d/opencv4.conf && \
    ldconfig
