A portable touch projection device, relating to the field of touch projection. The portable touch projection device comprises a rectangular housing (1), and a projector (3), an infrared laser emitter (5), an infrared camera (6), and a computer (2) that are accommodated in the rectangular housing (1). Lenses of both the projector (3) and the infrared camera (6) are both located at the top of the rectangular housing (1). A reflecting mirror (4) directly facing the lens of the projector (3) is disposed above the projector (3). A projected image is reflected and displayed on a desktop by means of the reflecting mirror (4), the infrared laser emitter (5) emits light to the desktop to form a light touch surface, the light touch surface is touched by a finger to form a light touch point, the infrared camera (6) receives a mirror image of the light touch point mapped in the reflecting mirror (4), an image information processing module processes the mirror image to obtain a coordinate position of the light touch point in the projected image, and the coordinate position is simulated into a mouse for interactive operation. The present device is small and exquisite in appearance and convenient to carry. A user interactively operates and controls a projected image by directly using a finger, such that the device is convenient to use. |
