The image processing module locally processes the image data based on the coordinate data on the coordinate system, and performs a superposition simulation of the original image data and the processed image data through the image integration module. The screen projection module projects the superimposed image data onto the projection wall.

[0040] The infrared laser irradiation and wall projection interactive device developed in this project is based on infrared laser visual detection technology. It uses simulated searchlights to illuminate the wall to achieve interaction with the wall projection content, and achieves real-time detection, real-time interaction, and non-delayed interaction. It can be applied to image display and interaction on large-size projection surfaces. This system provides a more interesting means of interaction for various exhibition halls. In addition to completing a set of underlying technologies including hardware structure design and basic detection technology, it also provides an upper-level interactive API interface, which is of great significance in the research and development of various interactive exhibits in museums.

[0041] The infrared interactive device is also provided with a visible light filtering module and a coordinate correction module. The visible light filtering module filters the light in the visible light range collected by the infrared spectrum camera module, and the coordinate correction module corrects the position of the recognition area sensed by the infrared spectrum camera module based on the shooting angle, so as to avoid visible light interfering with the operation and recognition of the infrared spectrum camera module and ensure accurate sensing and positioning of the recognition area.

[0042] The infrared interactive device includes the following structures: an outer shell, the outside of the entire device is fixed on the protective component; a top cover, which is detachable and used for equipment maintenance; a heat dissipation hole, which is located between the top cover and the bottom, and is used for heat dissipation; a top radiator, which is installed on the inside of the top cover of the device, and is used for internal heat dissipation; a bottom radiator, which is installed on the inside of the bottom cover, and is used for internal heat dissipation; a power interface, which is used to connect a power adapter, and the power supply adopts a 5V, 1A DC power supply; a USB debugging structure, which is used for debugging testing; a debugging network port, which is used for network debugging; a debugging indicator light, which is used during debugging, and different colors and flashing frequencies indicate different debugging states; a signal indicator light, which indicates the wireless signal connection status; a status indicator light, which indicates the normal working state of the device, green is normal, and red is abnormal; a power indicator light, which indicates whether the power supply is correctly connected; a battery, which uses a lithium-ion battery with a capacity of 1000mah; a main control circuit board, which is the main control circuit of the device, and mainly includes multiple control chip modules such as a network module, a security control module, a lighting control module, and a human body sensing control module; a protection module, which is used to protect the device from unexpected situations.

[0043] The infrared interactive device is also provided with a status display module, which includes a working status indicator light and a speaker for broadcasting the working status, a signal indicator light, and a power indicator light, which can be used to inform users and visitors of the operating status of the projection interactive device to ensure its standardized and reasonable use.

[0044] The image processing module is used to crop and enlarge a part of the original image data, or retrieve and enlarge the image data related to the identification area in the image data memory to form the processed image data.

[0045] The image integration module overlays the processed image data on the original image data, and performs blurring or cropping processing on the overlapping position of the original image data.

[0047] The working principle of an infrared laser searchlight wall projection display interactive device of the present embodiment is as follows: when there is no human interaction, the picture projection module projects some fixed animation pictures on the projection wall; when the audience interacts with the interactive remote control, the infrared laser emission module directly irradiates the wall and moves, so that an identification area is formed on the projection wall; the infrared spectrum camera module identifies the identification area and performs coordinate positioning on the coordinate system corresponding to the image data; at this time, the state switching module switches the operating state of the projection device to the interactive state, and the image processing module and the image integration module process the original image data of the projected and identified area, and superimpose it on the original image data, and refine and beautify it to ensure that it is convenient for visitors and users to recognize the image; finally, the superimposed image data is projected on the projection wall to realize the interaction between the projection display and the user's infrared laser irradiation, and the local amplification of the projection image and the extension and supplement of the content; the equipment is charged and maintained by the staff every few days.

[0048] Embodiment 2:

[0049] See also Figure 1 On the basis of the above-mentioned embodiment 1, preferably, a remote control module is provided on the interactive remote control, and the infrared laser emission module is provided on the infrared interactive device, and the remote control module controls and adjusts the direction of the infrared laser emission module, which is used to adjust the recognition area on the projection wall.

[0050] In this embodiment, the visitor's interactive operation method is to control the infrared laser emission module of the infrared interactive device on the top to emit infrared rays through the remote control module, thereby avoiding the mobile interactive remote control of embodiment 1 causing visitors to move around randomly and cause chaos in the venue, affecting the order of the exhibition hall and the interactive visiting operations of other people.

[0051] Embodiment three:

[0052] See also Figure 1 Based on the above-mentioned embodiment 1, preferably, the infrared laser emitting module is an adjustable light emitter for emitting 850nm infrared laser and adjusting the light intensity. The control host is provided with a distance sensing module for identifying the distance between the infrared laser emitting module and the projection wall. The distance sensing module is associated with the adjustment module for controlling the light intensity on the infrared laser emitting module.

[0053] The distance sensing module measures the emission and return time of the infrared laser based on the distance data obtained by identification. The infrared interactive device is also provided with an obstacle sensing module, which is used to receive the infrared laser emitted and reflected by the infrared laser emission module. When the time difference between the emission and reception of the infrared laser is less than the calculated time value of the distance sensing module, the infrared laser emission module is shut down.

[0054] In this embodiment, when visitors operate the interactive remote control and the distance between the infrared light emitting module and the projection wall changes during the interaction, the emitted light can be adjusted synchronously for light intensity, ensuring stable and efficient recognition of the infrared spectrum camera module while avoiding excessive infrared laser light intensity, which may cause harm to personnel and the venue environment. When the infrared light encounters visitors and obstacles on the moving path, the infrared laser emission module will be shut down, and the visitor will be prompted that the obstacle is blocked, thereby ensuring personnel safety, device safety, and the integrity and fun of the exhibits.
