Abstract

The invention discloses a joint point coordinate obtaining method and device, and electronic equipment and belongs to the technical field of computer vision. The method comprises steps that a specified number of depth cameras obtain multiple sets of original coordinates corresponding to multiple joint points of a target object, one set of original coordinates corresponding to one joint point of the target object comprise the specified number of original coordinates, and one set of original coordinates are obtained by collecting one joint point of the target object through the specified numberof depth cameras; the data processing center respectively acquires multiple groups of rigid transformation parameters taking the specified depth camera as a reference based on the multiple groups of original coordinates, one group of rigid transformation parameters corresponds to one group of original coordinates, and the specified depth camera is pre-specified from a specified number of depth cameras; the data processing center obtains a plurality of target coordinates of a plurality of joint points with the specified depth camera as a reference based on a plurality of sets of rigid transformation parameters and a plurality of sets of original coordinates, and one set of rigid transformation parameters corresponds to one target coordinate.

Description

technical field [0001] The present application belongs to the technical field of computer vision, and in particular relates to a method, device and electronic equipment for acquiring coordinates of joint points. Background technique [0002] With the rapid development of computer vision motion capture technology, the technical level of locating objects or human bodies is also constantly improving. In the prior art, the infrared optical positioning technology can usually obtain the three-dimensional coordinates of objects or human bodies at any position in the space by installing multiple emitters in the space. In addition, the traditional computer vision motion capture technology can use a depth camera to calculate the three-dimensional coordinates of the positioned object or human body based on the time difference and phase difference of light reflection emitted by the depth camera through Time of Flight (TOF) technology. [0003] In the process of implementing this applic...
