[0012] In the above technical solution, the preferred camera unit 7 includes an RGB camera, an infrared camera, or a TOF camera.

[0013] In the above technical solution, the preferred camera unit 7 includes a monocular camera, a binocular camera, a tri-lens camera, or a multi-lens camera.

[0014] In the above technical solution, the portable smart terminal 2 is preferably a mobile phone, tablet computer, or laptop computer.

[0015] In the above technical solution, when the signal connection between the content generation and execution unit 1 and the projection image processing unit 12 includes a wired connection, the wired connection at the content generation and execution unit 1 end is a detachable connection, and more preferably the detachable connection is a plug-in connection.

[0016] In the above technical solution, when the signal connection between the camera image processing unit 6 and the touch behavior recognition unit 4 includes a wired connection, the wired connection at the touch behavior recognition unit 4 end is a detachable connection, and more preferably the detachable connection is a plug-in connection.

[0017] The workflow of this utility model is as follows:

[0018] Step 1: The user opens the content generation and execution unit 1 through the portable smart terminal 2;

[0019] Step 2: The content generation and execution unit 1 transmits the signal to the projection image processing unit 12 in the projection and image acquisition accessory 5 via wired or wireless means (wireless means can be WiFi or Bluetooth);

[0020] Step 3: The projection image processing unit 12 transmits the processed signal to the projection optical engine 11 through the signal connection for projection. The image projection area 9 can be, but is not limited to, a screen, wall, desktop, floor, etc.

[0021] Step 4: Based on the actual situation of the image area 9, if the user needs to adjust the projected image, they can apply the preset gesture touch action 10, such as tap, drag, slide, zoom, handwriting and other common touch actions of smart terminals to the image area 9.

[0022] Step 5: The camera unit 7 acquires the image of the image area 9 and the touch action 10, and sends the acquired photographic signal to the camera image processing unit 6 through the signal connection;

[0023] Step 6: The camera image processing unit 6 transmits the processed signal to the touch behavior recognition unit 4 via a wired or wireless means (wireless means can be WiFi or Bluetooth);

[0024] Step 7: The touch behavior recognition unit 4 outputs the recognized signal to the control command generation unit 3 to generate control commands;

[0025] Step 8: The control instruction generation unit 3 generates control instructions and applies them to the content generation and execution unit 1 via signal connection;

[0026] Step 9: The content generation and execution unit 1 executes the control instructions of step 8, thereby realizing the touch control of the image in the image projection area 9.

[0027] The effects or advantages of this utility model are:

[0028] 1. The perception and recognition of user touch behavior and the generation of touch events do not require a dedicated projection touch screen or screen, additional touch input auxiliary equipment, or a separate touch recognition system. It can be achieved solely through camera acquisition accessories and touch recognition algorithms and touch event generation software on the user's smart terminal, which greatly simplifies the system complexity and system cost.

[0029] 2. For multimedia audio-visual entertainment distribution channels, no additional audio-visual entertainment playback system or equipment is required, which simplifies the system complexity and system cost;

[0030] 3. By organically combining a portable smart terminal with photography and image acquisition accessories, a simple, portable, easy-to-use, and economical touch projector has been achieved;

[0031] 4. The above-mentioned detachable connection makes it easy for the portable smart terminal 2 to be assembled into the touch projector of this utility model to perform touch projection tasks at any time. When there is no touch projection task, the portable smart terminal 2 can also be easily detached from the touch projector of this utility model to perform other smart terminal tasks, instead of using the portable smart terminal 2 exclusively for touch projection tasks, thereby helping to reduce the total cost of the touch projector.
