ABSTRACT
Accurate, fast, and anti-jamming extraction of frame is the primary tasks of the indoor scene reconstruction. The existing frame extraction methods are complex, and the extraction results are in low fitting degree with the real indoor frame. Extracting frame structure from the indoor scene is the primary task of indoor scene understands. The illumination, occlusion, and other interference make the computer automatically identify the framework full of challenges. For the five-sided indoor scene image, although the vanishing points in three directions are not all necessarily detected, there must be a vanishing point located inside the frame intersected by feature lines of other two directions. For the indoor scene frame structure detection method proposed in this paper, the feature lines in the direction of three vanishing points are important clue and foundation. According to the candidate corner vertices detected in the previous step, corner vertices of the frame will be determined.
