A bidirectional reflectance distribution function (BRDF) measurement system and method, an electronic device, and a storage medium. The BRDF measurement system includes: a blackbody, a spectroradiometer and a controller; where in case that the blackbody is heated to a target temperature, it undergoes a solid-liquid phase change; the spectroradiometer is used to measure the blackbody and transmit a first measurement signal to the controller, and in case that the blackbody irradiates a to-be-measured point on a sample surface, the spectroradiometer is further used to measure radiation from the to-be-measured point, and transmit a second measurement signal to the controller; and the controller is used to obtain a BRDF of the to-be-measured point based on the first measurement signal, the second measurement signal, the target geometric relationship, a target mapping relationship and a dimension parameter of the blackbody.
