Embodiments of the present disclosure may be used to install a target object in a target area. In the embodiment of the present disclosure, the target area may be any target installation area such as a wall surface or a furniture surface, and the target object may be any object such as a painting or a decoration that needs to be installed in the target area. For example, the target area is a rectangular wall surface, and the target object is a decorative painting to be installed on the wall surface.

In the embodiments of the present disclosure, the optical projection device may acquire the layout preview image in various ways. For example, the optical projection device may obtain the layout preview from the first terminal. The first terminal can be a mobile phone, a tablet computer, a computer or other terminal equipment.

In one possible implementation, the layout preview image may contain only the target object images corresponding to the target objects to be installed. In this implementation, the layout preview image may include target object images corresponding to one or more target objects to be installed.

In another possible implementation manner, the layout preview image may include an installed object image corresponding to an installed object and a target object image corresponding to a target object to be installed. In this implementation, the layout preview image may include installed object images corresponding to one or more installed objects and target object images corresponding to one or more target objects to be installed.

In a possible implementation manner, a target object to be installed may be placed on a plane (e.g., a table or a floor), and a first terminal with a camera may be used to capture a target object image corresponding to the target object. If a plurality of target objects need to be installed, the plurality of target objects can be placed on the plane at the same time, and the plurality of target objects can be shot at the same time.

Wherein the actual distance between any two points of the target object can be measured by the user. According to the actual distance between any two points of the target object and the positions of the two points in the target object image corresponding to the target object, the actual size information of the target object can be determined.

In step S122, the layout preview image is projected in the target area in accordance with the actual size information of the target object.

In the embodiment of the disclosure, the optical projection device may measure the distance between the galvanometer of the optical projection device and the wall surface by using a distance measurement component (e.g., a laser distance measurement sensor), and then accurately calculate the deflection angle corresponding to the galvanometer scanning mirror by combining with the actual size information of the target object, and the deflection angle may be controlled by a driving voltage, so that a control system of the optical projection device may generate the driving voltage according to the distance data fed back by the sensor and the actual size information of the target object, and control the deflection angle of the galvanometer scanning mirror, thereby automatically adjusting the projection size.
