Abstract
A method for automatically inferring a 2D scale range threshold to eliminate 2D object bounding boxes outside the target non-planar zone in a corresponding monocular image. The method leverages given camera parameters, 3D coordinates of the target non-planar zone vertices, and the real 3D scale of the target object. The process comprises three primary steps: 1) Deriving the real 3D object scale range from pre-acquired data, 2) Estimating the corresponding 2D bounding box scale range in the image using camera parameters, 3D coordinates of the target non-planar zone, and the real 3D scale range obtained in the first step, 3) Eliminating bounding boxes that fall outside the bounding box scale range.
