The embodiment of the invention discloses a sample set construction method, an image imaging method and device, a medium and electronic equipment. The method comprises the following steps: taking a preset initial shooting position as a starting point; taking a preset shooting ending position as an end point; gradually adjusting the shooting position between the preset starting shooting position and the preset ending shooting position; in each shooting position, taking the preset initial environment illumination as a starting point; taking a preset ending environment illumination as an end point; gradually adjusting the environment illumination between the preset starting environment terminal and the preset ending environment illumination for shooting; shooting at each shooting position toobtain a scene image set of the sample scene under different ambient illuminance; finally, combining scene images in the scene image set obtained through shooting into sample pairs, obtaining a sampleset used for training an image enhancement model. Due to the fact that noise distribution of the sample pairs in the sample set is real noise distribution, the image enhancement effect of the image enhancement model can be improved by training the image enhancement model through the noise distribution.
