Abstract
Provided are a lidar three-dimensional (3D) target detection method based on region pillar feature fusion and a system thereof. The method includes: collecting a point cloud data set of a target region and a coordinate thereof, determining a point cloud range and dividing the point cloud range into several sub-regions; calculating a maximum difference of a z coordinate in each sub-region, creating a feature array, and allocating the maximum difference to points in the sub-region to form a pillar feature. According to an area of a target, the allocation number is dynamically adjusted to obtain the target feature. The detection performance of the network for small targets is improved through region attention enhancement feature coding.
