Embodiment approach

[0044] In order to solve the problems in the prior art, such as figure 1 As shown, this embodiment provides a VR chemistry laboratory implementation method based on unity3D and hand motion capture, which includes the following steps:

[0045] S100, constructing a module and a chemical laboratory model in the VR experimental scene through modeling software;

[0046] S200, constructing a virtual environment required for the experiment in the VR experiment scene by using the unity3D engine;

[0047] S300, identifying the initial position of the user's hand, inputting the coordinates of the initial position of the user's hand to match the hand model in the VR experiment scene, and mapping hand movements to the hand model in the VR experiment scene in real time;

[0048] S400. Pop up corresponding text and voice prompts according to the user's operation to guide the user's operation.

[0049]The present invention constructs a virtual chemistry laboratory by using VR equipment and...

Embodiment 1

[0100] like image 3 As shown, this is a flow chart of preferred embodiment 1, which is a combustion property verification experiment.

[0101] The implementation steps are:

[0102] (1) The unity3D engine loads the laboratory environment, including preset experimental equipment and object groups in the laboratory.

[0103] (2) Initialize the hardware device, send the image stream to the VR device, and detect whether the gesture recognition hardware works normally.

[0104] (3) Gesture recognition hardware detects hand movements. The processing module analyzes the depth information of the hand according to the depth image of the hand, and recognizes the tapping action of the hand; initially, the user can view the hand image through the display provided in the gesture recognition hardware driver, and when the user confirms that the joint points of the fingers have been correctly When tracking, you can freely grasp any object you want to manipulate.

[0105] (4) When the ope...

Embodiment 2

[0113] like Figure 4 As shown, this is the flow chart of the preferred embodiment 2, which is a flame reaction experiment.

[0114] The implementation steps are:

[0115] (1) The unity3D engine loads the laboratory environment.

[0116] (2) Initialize the hardware device, send the image stream to the VR device, and detect whether the gesture recognition hardware works normally. Gesture recognition hardware detects hand movements. The principle is not repeated here.

[0117] (3) Pop-up text and voice prompts inform the operator of experimental background information.

[0118] (4) When the operator grasps the glass rod, the hand model coincides with the preset collision body on the glass rod. When a collision is detected, the grip script is triggered so that the glass rod can move with the hand.

[0119] (5) Put the bottom end of the glass rod into the hydrochloric acid, the bottom of the glass rod collides with the collision body inside the hydrochloric acid, and a promp...

Abstract

The invention discloses a VR chemical laboratory implementation method and system based on unity 3D and hand motion capture. The method comprises the following steps: constructing a module and a chemical laboratory model in a VR experiment scene through modeling software; a virtual environment required by an experiment in the VR experiment scene is constructed through a unity 3D engine; identifying the initial position of the hand of the user, inputting the initial position coordinate of the hand of the user to be matched with the hand model in the VR experiment scene, and mapping the hand action to the hand model in the VR experiment scene in real time; and corresponding character and voice prompts are popped up according to the operation of the user to guide an experimenter to operate. The virtual chemistry laboratory is constructed by using the VR equipment and the unity 3D engine, students are placed in a scene which cannot be realized in an original classroom, the students are promoted to deeply understand knowledge, an operator can operate experiment equipment in the virtual chemistry laboratory through a hardware interaction means, the training effect is improved, the experiment understanding is deepened, and the experiment efficiency is improved. Meanwhile, the cost is reduced and the safety is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a VR chemical laboratory implementation method and system based on unity3D and hand motion capture. Background technique [0002] In fact, educational resources are unevenly distributed, while educational competition exists everywhere. Some schools do not have relevant equipment to provide corresponding hardware support for experiments. A large number of high school students reported that they did not achieve the expected ideal goals due to lack of experimental training when participating in major subject competitions. At the same time, the experiment is included in the examination scope of the middle and high school entrance examination, but in actual teaching, students are rarely allowed to operate by themselves, resulting in the inability of subject thinking to penetrate into every detail. The fundamental reason is the limited funding. In order to reduce the cost, the pre...
