The invention discloses an automatic driving 3D modeling method, device and system. The invention relates to the technical field of automatic driving, and solves the problems that data modeling is incomplete due to single data sampling, or the relevance between data is poor, and an accurate 3D environment model cannot be created. According to the invention, the method comprises the steps of: obtaining and fusing data collected by the multi-element sensor to form a composite view, extracting inter-frame target parameters of the same detection target in a plurality of adjacent frames acquired bydifferent sensors in the comprehensive view; comparing and analyzing data acquired by different sensors; adopting a stepped threshold method to eliminate singular values and redundancy of data in different sensors, achieving accurate judgment of target parameters, and when the inter-frame target parameters of the same detection target in a plurality of continuous adjacent frames are within a preset threshold, determining
