Abstract in different language:	Reconstruction from real images has evolved very differently from reconstruction from sketches. Even though both present similarities, the latter aims to surpass the subjectivity that drawings present, increasing the task's uncertainty and complexity. In this work, we draw inspiration from reconstruction over real multi-view images and adapt it to work over sketches. We leverage inverse rendering as a refinement process for 3D colored meshes while proposing modifications for the domain of drawings. Compared to previous methods for sketches, our proposal recovers not only shape but color, offering an optimization system that does not require prior training. Through the results, we evaluate how different quality factors in sketches affect the reconstruction and report how our proposal adapts to them compared to directly applying existing inverse rendering systems for real images.
