Abstract: The invention discloses a control method of a laser projector. The control method of the laser projector comprises the steps: acquiring a projection distance between a target user and a laser projector; according to the projection distance, acquiring an energy density of the laser projector during laser projection based on a preset parameter at a current distance; and on the basis of the energy density and a safety energy threshold, adjusting a preset parameter and controlling the laser projector based on the adjusted parameter. In addition, the invention also discloses a control device of thelaser projector, a terminal, a computer-readable storage medium, and a computing device. According to the invention, the emission parameter of the laser projector can be controlled based on the projection distance between the target user and the laser projector and the projection energy density, so that a phenomenon that the user is injured because of too high projection energy density of the laser projector is avoided.
