A measurement and installation data indicating apparatus and a measurement and installation data indicating method capable of easily and appropriately measuring a target position are provided. The measurement and installation data indicating apparatus includes a distance image sensor (55) that obtains distance image data (62) in a predetermined range, a projector (56) that projects an image on a projection plane (13) in a predetermined range, an inclination data obtaining part (54) that obtains inclination data (61) on a detection optical axis (55a) and a projection optical axis (56a) relative to a vertical direction, a positional data obtaining part (12, 57) that obtains coordinate data (71) on a present position (75) and a target position (72), and a terminal controller (52) that generates, based on the coordinate data, a target information image (77) related to the target position and seen from the present position. The terminal controller (52) corrects the target information image (77) to fit to a shape of the projection plane (13) based on the distance image data (62) obtained by the distance image sensor (55) and the inclination data (61) obtained by the inclination data obtaining part, and projects the corrected target information image (77) by the projector (56).
