Embodiment Construction

[0019] Hereinafter, the specific process of the present invention will be described with reference to the drawings, but the present invention is not limited to the examples shown in the drawings.

[0020] Step 1 is a calibrated space, which has an absolute coordinate origin and space range, and any point inside corresponds to a definite three-dimensional coordinate value. The modeling of the target is limited to the Cartesian coordinate system.

[0021] Step 2 as figure 1 In the way shown in , the image information of different bands is captured in space.

[0022] Step 2.1 Use a plastic steel bracket to build a three-dimensional bracket at the edge of the calibration space, and place an infrared and visible light collection device to determine the coordinates and viewing angles at various angles around the center of the space at a suitable position on the bracket.

[0023] In step 2.2, the several infrared and visible light collection devices are used to simultaneously captu...

Abstract

The invention relates to a water current modeling data capturing device with combination of infrared rays and visible light and belongs to the technical filed of virtual reality science. The water current modeling data capturing device comprises a water current generation device, an infrared camera, a visible light camera, a lens filter disc, an infrared transmitter in a specific waveband, a cold light lamp and a semi-transmitting semi-reflecting mirror. In the invention, the water current morphological data capturing device at multiple angles and multiple wavebands is designed by using the principle that the physical properties of water in the visible light and the specific infrared waveband are different; the water current generation device has high reflectivity when exposed under the cold light lamp of the visible light waveband and has high-absorption physical property under a light source of the specific infrared waveband (2.4-3.5mum); the accurate surface segmentation is realized by using the water current morphological data under the multi-angle infrared rays; data captured under visible light are used for model render with higher reality sense; and the better dynamic water current simulation effect can be achieved by combining the water current morphological data acquired under the infrared rays with the data acquired under the visible light. By using the water current modeling data capturing device, dynamic water body biased data and visual information can be acquired simultaneously and accurately; and the modeling distortion caused by inaccurate edge in the traditional method is overcome.

Description

technical field [0001] The invention relates to a water flow modeling data capture device using infrared rays and visible light, and belongs to the technical field of virtual reality. Background technique [0002] Virtual reality technology is a technology that better adapts to and utilizes nature by understanding nature and simulating nature. It usually simulates real objects in the real world in a virtual scene environment, pursuing the sense of reality and immersion of people in the virtual environment. sense, using the virtual to extend, direct, and improve reality. Simulating real objects in virtual scenes exists as the most commonly used expression method of virtual reality technology, and the modeling work using multi-angle video streams of the same object is a typical representative. There are many classical algorithms for multi-angle video modeling, and its advantages in real-time and accuracy make it an important position in virtual reality technology. [0003] T...
