Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] In the semantic segmentation algorithm used in autonomous driving, unknown road obstacles cannot be identified. The present invention uses the fusion result of the three-dimensional point cloud and the two-dimensional image to perform plane fitting on the coordinates of the three-dimensional point cloud corresponding to the road area of the image, and then calculates the distance of each point relative to the fitting plane. Mark the points whose distance is greater than a certain threshold, and then perform region growth on all the above points in 3D space. Finally, each grown 3D region block is marked as an unknown road obstacle to guide the vehicle to avoid road obstacles on the driving route.
[0032] The invention discloses a method for discriminating unknown obstacles in three-dimensional semantic segmentation of road scenes. Fir...
