What it is

Slambook is a comprehensive C++ codebase accompanying the textbook '14 Lectures on Visual SLAM: From Theory to Practice' (2017). It implements visual Simultaneous Localization and Mapping (SLAM) from first principles, covering rigid body motion, feature-based odometry, direct methods, bundle adjustment, loop closure detection, and dense reconstruction using libraries like Ceres, g2o, and DBoW3. Chapter-based monorepo: ch2–ch13 directories contain topic-specific C++ implementations; ch10 (backend optimization) has two separate implementations via ceres_custombundle/ and g2o_custombundle/ with shared common/ code for BALProblem, BundleParams, and projection utilities. 3rdparty/ holds all…

Open these first:

• README.md — Essential overview explaining this is code from "14 Lectures on Visual SLAM" book; describes chapter organization and…
• ch10/g2o_custombundle/g2o_bundle.cpp — Core bundle adjustment implementation using g2o library; demonstrates pose graph optimization which is central to SLAM…
• ch10/ceres_custombundle/ceresBundle.cpp — Alternative bundle adjustment implementation using Ceres solver; shows custom cost functions for camera pose and landmark…
• ch11/pose_graph_g2o_SE3.cpp — Pose graph optimization using SE(3) Lie groups; demonstrates loop closure and pose graph construction for backend…
• ch12/loop_closure.cpp — Loop closure detection implementation using DBoW3 vocabulary tree; critical for place recognition in SLAM systems

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/gaoxiang12/slambook.git
cd slambook
# Extract dependencies (requires manual compilation)
cd 3rdparty
tar -xzf Sophus.tar.gz && tar -xzf g2o.tar.gz && tar -xzf ceres-solver.tar.gz && tar -xzf Pangolin.tar.gz && tar -xzf DBow3.tar.gz
# Build a specific chapter (e.g., ch3 for Eigen basics)
cd ../ch3 && mkdir build && cd build && cmake .. && make

Daily commands:

CMake-based: cd ch<N> && mkdir build && cd build && cmake .. && make. Each chapter has independent CMakeLists.txt. No single 'main' entry point—run individual chapter executables after build. Examples: ./ch7_vo_mono…

…shortened for this brief.

Key cautions & unknowns

• Stale — last commit 2y ago
• Dependency hell: Sophus, g2o, Ceres, and Pangolin must be manually compiled from tarballs in 3rdparty/—no vcpkg, conan, or apt integration. Some tarballs may require Ubuntu 16.04-era libraries; modern Ubuntu (20.04+)…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
