The invention discloses a method, a device and equipment for determining an aerial photography area based on BIM (Building Information Modeling) information of water transportation navigation channel engineering, relates to the technical field of water transportation navigation channel engineering, and aims to solve the problems of inaccurate aerial photography area determination and low aerial photography efficiency in the prior art. The method comprises the steps of determining a first offset distance and a second offset distance based on a channel width in a channel BIM model; performing reverse offset operation on the channel center line along the directions of the two banks of the channel according to the first offset distance and the second offset distance in the BIM model to obtain first edge information and second edge information; performing reverse offset operation at the start and end points of the channel according to a second offset distance to obtain third edge information; forming a first targe
