Abstract

The invention provides a three-dimensional object absolute attitude control method and device based on a fingerprint image, and the method comprises the steps: collecting a fingerprint image of a current finger in real time; speculating the three-dimensional posture of the current finger according to the sequence image; mapping the three-dimensional posture of the current finger into a three-dimensional input signal, and controlling the absolute posture of the target object in the three-dimensional space according to the three-dimensional input signal; and taking the absolute attitude obtained after control as a target attitude, and calculating a conversion path for converting the controlled object to the target attitude. According to the three-dimensional absolute attitude control method, the existing man-machine interaction mode can be effectively expanded, and convenience is provided for object attitude control in a three-dimensional space.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to the problem of three-dimensional attitude control. Background technique [0002] With the continuous development of human-computer interaction technology, the way of interaction between humans and machines has been constantly changing and developing. In the fields of games, virtual reality (VR), security monitoring, spacecraft control, vehicle control, robot control, 3D design, etc., most objects such as cameras, 3D models, airplanes, and cars exist in 3D space, so they can be accurately and efficiently It is a very important requirement to control the 3D pose of the target object. In the existing technologies, there are still few object attitude control systems that directly output three-dimensional control signals. The commonly used control input device is a traditional mouse, and then control the moving direction, speed and displacement distance of the mouse on the t...
