Embodiment 1

[0035] see figure 1 , the present embodiment provides a scientific display device based on projection technology, the scientific display device includes a three-dimensional model display device 11 , a depth detection device 12 and a projector 13 .

[0036] Wherein the three-dimensional model display device is a sand table, with the advancement of technology, the three-dimensional model display device can also be a large flexible screen with a simulated shape.

[0037] The depth of field detection device is connected to the projector, and the projection direction of the projector and the detection direction of the depth of field detection device are parallel to and perpendicular to the plane where the table top of the three-dimensional model display device is located.

[0038] The depth of field detection device includes an infrared emitter and an infrared receiver, the infrared emitter is used to emit an infrared speckle field, and the infrared receiver is used to receive feed...

Embodiment 2

[0060] This embodiment is basically the same as Embodiment 1, the only difference is:

[0061] The scientific demonstration device, the sand table, includes a reference surface.

[0062] The projector is used to project an image of one color on a first target area on the model, wherein the first target area is an area on the model that is a preset distance away from the depth-of-field detection device, The values ​​within the preset distance interval are all smaller than the distance from the reference plane to the depth-of-field detection device;

[0063] The projector is used to project an image of one color on a second target area on the model, wherein the second target area is longer than the base surface reference on the model from the depth detection device face to the length of the depth detection device.

[0064] With the scientific display device, the projection method includes:

[0065] The projector projects an image of one color on a first target area on the mod...
