Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
G2O's documentation assumes a strong background in graph optimization and robotics, making it challenging for beginners to understand and implement.
While G2O is written in C++, there are no official bindings or libraries provided for other languages such as Python or Java, limiting its accessibility to developers who prefer these languages.
Setting up the environment and dependencies for G2O can be cumbersome, especially on non-standard platforms or configurations, leading to potential frustration during initial integration into projects.
G2O may suffer from performance degradation when dealing with very large graphs due to its memory management and optimization algorithms, which can be a bottleneck in real-time applications.
