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 work support system includes a measurement apparatus measuring a state of each of multiple measurement points on an object surface of a workpiece, a projector apparatus, and an arithmetic apparatus creating a projection image of the projector apparatus based on a measurement result of the measurement apparatus. The arithmetic apparatus calculates a difference between a state measured by the measurement apparatus and a target state for each of the multiple measurement points, and creates the projection image such that a picture of a characteristic point representative of the difference at each of the multiple measurement points is projected by the projector apparatus at a position of a corresponding measurement point on the object surface of the workpiece.

Abstract: A laser beam projector to be employed in an automatic welding machine, such as a robot, includes an optical head that projects a laser beam and a holding and turning mechanism that holds and turns the optical head. The spot of the laser beam can be accurately located on the portion to be welded by turning the optical head by the holding and turning mechanism.

Abstract: A weld portion detector (20) and a laser beam projector (10) disposed a predetermined distance behind the weld portion detector (20) are moved together. The weld portion detector (20) detects a weld line and the laser beam projector (10) projects on the weld line detected by the weld portion detector (20) for laser welding. Pieces of data on weld positions sequentially detected by the weld portion detector (20) are stored sequentially in combination with times when the pieces of data on the weld positions are obtained and moving speeds of the weld portion detector (20) in a memory. A time when the weld portion detector (20) passed a point at which the laser beam projector (10) has just arrived is calculated on the basis of the times and the moving speeds stored in the memory. The laser beam projector (10) projects a laser beam on a weld position detected at the thus calculated time.
