Focusing method and device, projection equipment and storage medium

The invention provides a focusing method and device, projection equipment and a storage medium, and relates to the technical field of projection. The method comprises the following steps: determining a motor step number corresponding to a projection clear point of the projection equipment under the current projection distance by adopting a pre-constructed calculation model according to the obtained current projection distance of the projection equipment; driving the motor to move the motor step number to reach a target position, shooting at least two projection images according to a preset time interval in the moving process of the motor, and determining the definition of each projection image; if the definition of each projection image is sequentially increased according to the shooting time of each projection image, determining the position of a target clear point according to the definition of the corresponding shot image when the motor is at the target position and the definition of the corresponding shot
