Object control method and device, electronic equipment and storage medium

Abstract

The invention relates to the technical field of computers, in particular to an object control method and device, electronic equipment and a storage medium. According to the object control method provided by the embodiment of the invention, the position change information of the target control part is determined based on the acquired target image information, and the current actual offset of the control object is determined based on the current position change information and the historical actual offset of the control object; and the position of the control object is updated based on the current actual offset, so that the influence of shaking of the target control part or fluctuation of position change of the target control part on the moving track of the control object can be relieved, the moving track of the control object is smoother, and user control is facilitated.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to an object control method, apparatus, electronic device, and storage medium. Background technique [0002] Gesture tracking (Tracking) uses the information obtained by image recognition technology to map the coordinate changes of the key points of the hand in the two-dimensional space of the image to the corresponding cursor position changes on the TV / computer, so as to realize the somatosensory sensation of the TV / computer and other specific equipment. Mouse control. Different from traditional mouse devices, the use of gesture tracking is completely dependent on the free movement trajectory of the user's hand key points in three-dimensional space.

AI Technical Summary

Problems solved by technology

Different from the traditional mouse device, the use of gesture tracking completely depends on the free movement track of the key points of the user's hand in three-dimensional space. There is no desktop support of the traditional mouse device during use, so the gesture tracking process is more likely to be affected by the arm. , wrist, fingers, and the unconscious and non-subjective behavioral influences of the human body

If the coordinate changes of the key points of the hand in the two-dimensional space of the image are directly mapped to the display device to form a cursor position change without any processing, it will be too sensitive and difficult for the user to manipulate

[0003] Some schemes that use sensors (such as gyroscopes) for cursor tracking control are usually based on digital signal processing techniques such as Fourier analysis, filter design, and filter cascading to realize the identification and elimination of trembling signals. The calculation of such algorithms The complexity is high, and the computing power of the device is high, so it is not suitable for use in gesture tracking with high real-time requirements.

In addition, because some users' gesture trembling amplitude has exceeded the general noise range, it is difficult to distinguish them from subjective and conscious actions, so extremely complex signal analysis and filter design are required, and the requirements for algorithm design and adaptation are high, and the implementation cost is relatively high. high
