Problems solved by technology

Although the traditional screen-based battlefield electronic sand table can also display three-dimensional scenes, the display method is a two-dimensional computer screen, which does not conform to people's visual habits
Limited by physical display equipment, all commanders can only observe the situation from the same perspective, and the information display is not sufficient to meet the needs of group discussions

Embodiment approach

[0078] ①The implementation of gesture interaction is as follows: Considering the limited samples and the accuracy of recognition, the SVM classifier is used to classify and recognize gestures. Gesture recognition based on the projection template method mainly projects three kinds of gesture images onto the horizontal and vertical coordinate axes respectively, and compares them with standard templates to obtain gesture recognition results. However, due to the low resolution of the depth map itself and the algorithm’s Interference is weak, so the algorithm is limited by distance. Perform smoothing and noise reduction on the hand image, and remove some interfering isolated point blocks to obtain a hand contour that meets the conditions. The following gesture features are then computed:

[0079] Circularity:

[0080]

[0081] This feature describes the degree to which the hand shape is close to a circle. The closer the value is to 1, the more the hand shape is similar to a ci...

Abstract

The invention discloses a HoloLens-based battlefield situation construction and interaction implementation method. The method sequentially comprises the following steps of 1, firstly, sequentially constructing a terrain model, a three-dimensional object model and a three-dimensional military standard, and then adopting the mode of combining geometric characteristic optimization and grain optimization for performing model optimization; 2, sequentially achieving the purposes of battlefield situation dynamic showing fluency and authenticity and the purpose of three-dimensional virtual-real fusion; 3, performing user interaction. The method can achieve construction and interaction according to user identity roles, operation habits, interaction action tendencies and other natural human-machine interaction holographic battlefield situation electronic sand table information, the situation awareness fidelity and immersion can be enhanced, the method can intelligently and efficiently provide the imaginable and visual battlefield situation and visualized information interaction interface for commanders and the staff, and the method is used for supporting construction of intelligent information service systems of future advanced command posts with different fight persons and different operation patterns.

Description

technical field [0001] The invention relates to an information service technology based on a mobile smart wearable device, in particular to a method for implementing battlefield situation information construction and interaction based on HoloLens. Background technique [0002] Battlefield situation display is a visual expression of battlefield situation information, and its display content is determined by the need to fully and accurately express battlefield situation information. According to the basic theory of combat command, battlefield situation information includes main factors such as units, personnel, equipment, facilities, deployment, and actions. Therefore, the content displayed on the battlefield situation corresponds to it, and also includes the above six main contents. The form of battlefield situation display is determined by the needs of combatants to obtain battlefield situation information intuitively, efficiently and unambiguously. [0003] Traditional bat...
