INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, PROGRAM, PROJECTION DEVICE, AND INFORMATION PROCESSING SYSTEM

The present technology relates to an information processing device, an information processing method, a program, a projection device, and an information processing system with which it is possible to correct the distortion of a projected image using a discretionary imaging device. An information processing device in one aspect of the present technology detects corresponding points on respective images on the basis of a projected image which is projected to a projection surface by a protection device and a plurality of captured images obtained by imaging the projected image at a plurality of imaging positions, estimates an imaging parameter that includes the plurality of imaging positions and attitudes during imaging time at the respective imaging positions and a projection parameter that includes the position and attitude of the projection device on the basis of corresponding-point information that represents the relationship of the corresponding points, generates correction data used for the geometric correc
