Walt Disney has filed a patent for a method to project content from a moving projector. The method involves analyzing an object to identify a projection surface, determining the position of the projector relative to the surface, modifying frames of content based on the position, and projecting the modified frames onto the surface. The modification of frames can include changes in pixel hue, position, discarding or adding pixels, based on the distance change of the projector between positions.

A recently filed patent (Publication Number: US20230206790A1) describes a method for projecting content onto a projection surface using a projector. The method involves several steps to ensure accurate and dynamic projection.

The first step is to analyze the object and identify a suitable projection surface. This could be a building or any other object with a surface suitable for projection.

Next, the method determines the initial position of the projector relative to the projection surface. Based on this position and the characteristics of the projection surface, the first frame of the content is modified to optimize the projection.

Once the first frame is modified, it is projected onto the projection surface from the projector.

The method then determines a second position for the projector, which is different from the initial position. The second frame of the content is then modified based on the projection surface and the new position of the projector. This modification can involve adjusting pixel hue, position, discarding or adding pixels, depending on the change in distance between the projector and the projection surface.

Finally, the second frame of the content is projected onto the projection surface from the projector.

The patent also mentions additional features and variations of the method. For example, the projection surface can be formed on a building or any other object. The projector can move arbitrarily or along a predetermined path between the initial and second positions. The projector can be mounted on a vehicle for mobility.

The method also involves analyzing the angle between the projector and the projection surface to ensure the projection falls within a desired range.

To determine the initial position of the projector, a sensing light is projected onto the projection surface, and the reflection data is analyzed. This can involve using laser beams arranged to reflect at different locations on the projection surface.

The object is analyzed to identify the projection surface by analyzing its texture and approximate size of surfaces between architectural openings.

Another variation of the method involves analyzing object characteristics that impact the projection of video content. This can include determining the reflectivity, hue information, pattern information, planarity, occluded surfaces, or aspect ratio of the object's surfaces.

The projection surface can be a portion of an exterior surface of the object or extend across multiple separate surfaces.

The method may also involve using a separate detector to detect object characteristics. This can involve projecting light from the detector onto the object and analyzing the object with the projected light to determine its characteristics. Multiple laser beams can be used for this purpose.

Overall, this patent describes a method for projecting content onto various surfaces using a projector, with the ability to dynamically modify the content based on the position and characteristics of the projection surface and the object being projected upon.
