Motion analysis device and method

Abstract

The invention discloses an action analysis device. The device comprises a projection unit, an image acquisition unit and an analysis and control unit; the projection unit is used for projecting an image of an action sensing area on a first projection plane and projecting action indicating information on a second projection plane under the control of the analysis and control unit; the image acquisition unit is used for acquiring the image of the action sensing area and sending the acquired image of the action sensing area to the analysis and control unit; the analysis and control unit is used for controlling the projection of the projection unit; when the image of the action sensing area indicated by the current action indicating information is judged to be blocked by an object by analyzing the image of the action sensing area received from the image acquisition unit, the current action is determined to be accurate. The invention further discloses an action analysis method. The use of the invention can avoid the limitations caused by the device shape and a sensor of the prior action analysis device.

Description

technical field [0001] The invention relates to image analysis technology, in particular to a motion analysis device and a motion analysis method. Background technique [0002] At present, motion analysis devices are often used to provide leisure and entertainment services, such as dancing machines and drumming machines realized by using motion analysis devices. Taking the dancing machine as an example, the existing dancing machine includes a stepping unit, a display unit and a central control unit, and these three units can be integrated into a dancing machine shell. Wherein, the display unit is a monitor, which is used to play music under the control of the central control unit and display the position that the player should step on along with the beat of the music, for example: up, down, left, right; the stepping unit includes a plurality of stepping position indications Each indication area is connected to a sensor. When the player steps on a certain indication area acc...

Problems solved by technology

Under the limitation of appearance, a motion analysis device can only realize one function, so the function is single, and motion analysis devices with different functions are not compatible

Moreover, the current motion analysis device uses the sensor as the motion signal sensing element. If the sensor fails, the analysis accuracy of the entire motion analysis device will be greatly reduced.
