Abstract
A projection position guiding method adapted to a projection system is provided. The projection system includes a projection target, an image capturing device and a projector. The projection position guiding method includes: projecting a projection content onto the projection target by the projector to generate a projection image, the projection content includes multiple positioning grid points arranged at intervals; capturing the projection target by the image capturing device to generate a captured image, and the captured image includes at least part of the projection image; and determining whether the positioning grid points satisfy multiple recognizable conditions according to the projection image in the captured image, when it is determined that the positioning grid points include at least one unrecognizable grid point that does not satisfy at least one of the recognizable conditions, adjusting a color of the at least one unrecognizable grid point in the projection content.
