Abstract: The information projection system includes stereo cameras, a controller, and projectors. The controller has a communication device, an analysis unit, a registration unit, and a projection control unit. The communication device acquires sets of appearance information in which each stereo camera detects an appearance of a workplace. The analysis unit analyzes the sets of appearance information, and creates a map information indicating shapes and positions of objects existing in the workplace. The registration unit creates and registers a work status information based on the map information that is individually created from the sets of appearance information respectively detected by the plurality of stereo cameras. The projection control unit creates an auxiliary image for assisting a work based on the work status information, and outputs the auxiliary image to each projector.

Abstract: A deformation processing support system acquires target shape data of a work having a reference line; acquires intermediate shape data from the work in an intermediate shape having a reference line marked thereon; and overlaps the two data on each other by aligning the reference lines relative to each other, to calculate a necessary deformation amount of the work based on a difference between the two data overlapped on each other. To align the reference lines with each other, first and second alignment axes with the same length calculated for the respective reference lines are superimposed on each other. Subsequently, the intermediate shape data is relatively rotated with respect to the target shape data around the first alignment axis.
