The invention provides a paleontology fossil three-dimensional modeling method based on oblique photography, which comprises the steps of paleontology fossil preparation and placement, fossil photographing, aerial triangulation measurement, model production, establishment of an irregular triangulation network according to an aerial triangulation measurement result, automatic matching of texture mapping work, evaluation of texture quality, and the like. And if the key part is fuzzy, wiredrawing and the like, reasons need to be found out for re-modeling. And finally, cutting the model according to the model cutting range, exporting a corresponding model format and finishing according to actual requirements, and performing model finishing and repairing on a generated result, which mainly comprises vulnerability filling, flying object deletion and the like. And necessary description, legend, copyright and other information are added. According to the method, the paleontology fossil is subjected to three-dimension
