Abstract

The invention relates to an interactive projection system, a depth sensor and a calibration method for a projector. The interactive projection system includes a depth sensor, a projector, and an imaging screen; the depth sensor is used to collect the depth information of the imaging carrier; the projector projects the image based on the depth information; the imaging screen is placed within the projection range of the projector, It is used to image the image of the reference object projected by the projector, and to calibrate the spatial position of the depth sensor or projector according to the imaging on it. By adopting the interactive projection system and the calibration method of the depth sensor and the projector of the present invention, the calibration is convenient, fast and accurate.

Description

technical field [0001] The invention relates to an interactive projection technology, in particular to an interactive projection system and a calibration method for a depth sensor and a projector. Background technique [0002] The interactive projector consists of a projector and a depth sensor (built-in color sensor, such as kinect), which can be projected on non-planar objects, and the projected image can change according to the shape of the object. For example, when projecting on sand, when the sand is piled at different heights, the projector can detect changes in the position and height of the sand pile, and change the projected image, such as projecting an image of a volcanic eruption on the sand pile, to achieve accurate virtual and A combination of reality. In this way, users can interact with the projected virtual image by changing the position and shape of the sand pile. [0003] Such an interactive projector first needs to calibrate the spatial position of the d...
