Embodiments of the presnet invention provide a projection terminal and a projection touch-control implementation method therefor. The terminal comprises: a structural body, a projection device arranged on the structural body and configured to project visible light frames on a projection region; an infrared distance measurement sensor array arranged on the structural body and forming an infrared touch-control region, wherein he infrared touch-control region at least partially overlaps the projection region; and a processing device connected to the infrared distance measurement sensor array and configured to control the touch-control detection of the infrared distance measurement sensor array and convert a touch-control detecting result into a control instruction. The infrared touch-control region formed by the infrared distance measurement sensor array at least partially overlaps the projection region. Therefore, the processing device performs conversion on the touch-control detecting result to form the control instruction corresponding to the visible light frames, and the projection touch control can be realized. Because the complex image processing technology is not needed, the technical difficulty for realizing the projection touch control is greatly reduced.
