Abstract
The embodiments of the disclosure relates to the technical field of projection adjustment. Embodiments specifically disclose a self-adaptive adjustment method and adjustment system for brightness of a projection apparatus. In the disclosure, ambient illuminance and a projection distance of the projection apparatus are obtained by controlling an illuminance sensor and a distance sensor, and a functional relationship among the ambient illuminance, projection plane illuminance and the projection distance is found through analysis and modeling of a large amount of data.
