Disclosed are a road pedestrian classification method and a top-view pedestrian risk quantitative method in a two-dimensional world coordinate system, which belongs to the field of moving object tracking and processing and is intended to solve the problem of enriching the existing road pedestrian classification. Images of road pedestrians are captured by an in-vehicle camera, and the road pedestrians are classified according to magnetic relationships among the road pedestrians shown in the images; the magnetic relationships are characterized by moving speeds of the pedestrians, relative distances between the pedestrians in the images and relative distances between the pedestrians and the camera; the pedestrians are classified, according to the magnetic relationships, by the moving speeds of the pedestrians, the relative distances among the pedestrians in the images and the relative distances between the pedestrians and the camera, and the determination of the magnetic relationships can ...

The invention provides a solvent type acrylate pressure-sensitive adhesive as well as a preparation method and application thereof. The solvent type acrylate pressure-sensitive adhesive is prepared from the following raw materials: an acrylic acid soft monomer, an acrylic acid hard monomer, a functional monomer, modified talcum powder, octa-amino cage type silsesquioxane, an initiator and a solvent. The octa-amino polyhedral oligomeric silsesquioxane is adopted as a cross-linking agent, the further cross-linking effect of amino and acrylic anhydride is utilized, the holding power of the pressure-sensitive adhesive is improved, meanwhile, the modified talcum powder is added in a matched mode, the peel strength and high-temperature resistance of the pressure-sensitive adhesive are improved, the modified talcum powder and the octa-amino polyhedral oligomeric silsesquioxane can generate a synergistic effect, and the adhesive force of the pressure-sensitive adhesive is improved. The holding ...
