The invention relates to the technical field of wind tunnel tests, in particular to a wind tunnel test aerodynamic load measuring device and method, and the device comprises an installation module, a ball model, an image collection module and a data processing module. The installation module is installed on a wind tunnel test section and used for suspending the ball model in a flow field area of the wind tunnel test section through a suspension line. The image acquisition module is used for horizontally shooting an image of the ball model from one side of the flow field; and the data processing module is connected with the image acquisition module and is used for acquiring images at different moments, determining the position of the ball model, fitting a curve changing along with time and calculating the aerodynamic load of the ball model in the flow field. According to the invention, the aerodynamic load in the wind tunnel flow field can be measured in a non-contact manner. 本发明涉及风洞试验技术领域，尤其涉及一种风洞试验气动载荷测量装置及方
