Embodiment Construction

[0028] The schematic diagram of the present invention shown by the party figure 1 As shown, the specific implementation is as follows:

[0029] Step 1. Collect gesture information, that is, capture finger information to complete gesture definition and collection. The implementation method is as follows:

[0030] Run the LeapMotion controller to calculate the hand’s moving direction, velocity, displacement, pitch angle, roll angle, yaw angle, etc. The situation defines three gestures: up and down, forward and backward, left and right. Obtain target information captured by LeapMotion, extract useful information related to gestures, and define three commonly used gestures: up and down, forward and backward, left and right.

[0031] The introduction of LeapMotion is as follows:

[0032] The LeapMotion controller adopts the principle of stereo vision, according to the two built-in cameras to simultaneously capture the target from different angles, and reconstruct the motion info...

Abstract

The invention discloses a Leap Motion based 3D commodity display method, and belongs to the technical field of mode identification. The method comprises the following steps: step 1, acquiring gesture information; step 2, judging an upward-moving gesture and a downward-moving gesture, if the gesture is the upward-moving gesture or the downward-moving gesture, entering the step 6, and if the gesture is neither the upward-moving gesture nor the downward-moving gesture, judging a forward-moving gesture and a backward-moving gesture; if the gesture is the forward-moving gesture or the backward-moving gesture, entering the step 6, if the gesture is neither the forward-moving gesture nor the backward-moving gesture, judging a leftward-moving gesture and a rightward-moving gesture, if the gesture is the leftward-moving gesture or the rightward-moving gesture, entering the step 6, and if the gesture is neither the leftward-moving gesture nor the rightward-moving gesture, entering the step 1; and step 3, establishing a 3D commodity model; and step 4, exporting a model file, namely, a *.osm file, required for scene rendering.

Description

technical field [0001] The invention relates to a 3D commodity display method based on LeapMotion, and belongs to the technical field of pattern recognition. Background technique [0002] Commodity online display is a key link in e-commerce, comprehensive and real commodity display can effectively promote the development of e-commerce. The current online display of commodities mainly includes two-dimensional plane display and 360-degree product display. The display of most commodities such as Taobao, Jingdong Mall, Amazon, etc. is only a static picture or still stays on a two-dimensional plane, which cannot be truly and comprehensively displayed. Commodity features, the latest three-dimensional product display, such as Philips, Taobao, Amazon and other products are displayed in the form of animation and 360-degree panoramic video, but lack of interaction with consumers, and the advertising method is relatively simple, unable to fully express the product characteristics, str...
