Abstract
Disclosed are a projection device and a projection method. The projection device includes an optical engine, a distance measuring unit, and a processor. The distance measuring unit is configured to emit testing light to the target area and receive reflected light. The distance measuring unit generates multiple pieces of corresponding distance information according to the reflected lights received and multiple areas of the target area. The processor is configured to: generate area distance information according to the multiple pieces of distance information; select a mode from multiple pieces of sub-area distance information comprised by each piece of area distance information as corrected distance information corresponding to each area; and control the optical engine to project an image beam according to the corrected distance information of each area to form a projected image in the target area.
