　　 Common ground interactive projection forms

1、 Ground interaction plant and flower projection

The ground is full of images of various flowers in bud and in full bloom. When people walk on flowers in different open states, there will be an interactive effect of blooming, withering, and petals moving with footprints, which is suitable for creating an atmosphere in art themed exhibition halls.

The interactive projection of fish and water on the ground, when people walk on the ground, the ground will appear the effect of ripples shaking, grass swaying, water flow changing direction, fish avoiding and swimming elsewhere. This kind of projection method can be applied to exhibition halls with environmental protection, ocean, biology and other themes. This ground interactive projection project can also be used in shopping malls and restaurants to quickly attract the attention of people.

3、 Interactive projection of ground cracking and collapse effect

Similar to the ice surface cracking, the image initially presents a solid ground projection interaction. When people walk, the ground begins to crack and collapse downward, and the collapsed part changes into the seabed, galaxies and other scenes. According to different exhibition themes and display needs, it can also be replaced by scenes such as ice cracking and sinking, desert sand blowing, etc.

4、 Ground projection interactive football

Players can use their feet to operate the billiards on the virtual game interface by stepping forward and hitting the billiards into the opponent's column to score.

　　 Requirements for ground interactive projection conditions and installation

Interface requirements and environmental requirements for ground projection

1. Projectors, cameras and infrared lights need to be hoisted: the ceiling height is about 3-4 meters or there is a fixed structure at this position.

2. Usually, the ground interactive projection is indoor. The main reason is that the outdoor light is too strong, which has an impact on the projection function. For example, when we look at the large screen on the wall in the outdoor, we will have confusion. The interactive projection also has requirements for light, and it is a light source that does not change or move.

3. In addition to light, the ground interactive projection is usually projected on the smooth and lubricated ground. If the ground is pitted, it will inevitably have an impact on the projection. In addition to these constraints, the installation requirements of the ground interactive projection are still quite simple. For example, it is not restricted by the size of the ground and can be customized according to the needs of customers. It is simple in installation and convenient to replace the site, and it is still very fast in later protection.

　　 Ground interactive projection installation

1. Installation of projector: the projector shall be installed above the ceiling and shall be projected downward, with a distance of about 3 meters from the ground.

2. Camera installation: the camera is installed next to the projector (near the projection port), and the direction of the projected image is consistent with the direction of the image captured by the camera, and the distance from the ground is consistent with the distance from the projector.

3. Board installation: The board is installed to the PCI interface of the computer and fixed with screws. Connect the attached braid cable to the board card and tighten the screws on the braid cable.

4. Equipment connection: the projector is connected to the VGA video interface of the computer, and the camera is connected to the V1 cable of the braid cable with a signal cable. Connect the power supply separately to complete the connection.

5. Projector requirements: resolution: 1024 * 768, brightness: 3000 lumens or more. The projector using DLP display technology has high cost performance.

6. Computer requirements: Generally, the CPU should be P4 or above (dual core as far as possible), and the L2 cache should be as large as possible (4M or above).
