Rigid-body collision track prediction display unit

Abstract

The invention provides a rigid-body collision track prediction display unit. The rigid-body collision track prediction display unit is composed of an aerial camera, a collision view angle camera, a wearable observation device, an aiming adapter, data processing equipment and a rigid-body collision track prediction software system. The rigid-body collision track prediction software system is configured in the data processing equipment, and is divided into a camera calibration system, an object identification system, a spatial posture calculating system and a rigid-body track estimation system. The spatial positions of rigid bodies on the working plane and the posture and force of the colliding party are obtained by analyzing video data transmitted by the aerial camera and the collision view angle camera by combination with spatial pose information transmitted by the aiming adapter, so that possible movement tracks generated after the colliding party and the collided party collide are obtained through calculation, and the tracks and actual scenes are overlapped to be displayed on a display screen of the wearable observation device. The collision tracks can be predicted and displayed in real time, and users can adjust the positions and movement states of the rigid bodies before collision happens.

Description
