The invention discloses a three-dimensional gesture
estimation method and a three-dimensional gesture
estimation system based on depth data. The three-dimensional gesture
estimation method comprises the following steps of S1, performing
hand region of interest (ROI) detection on photographed data, and acquiring hand depth data, wherein the S1 comprises the processes of (1), when bone point information can be obtained, performing hand ROI detection through single bone point of a palm; (2) when the bone point information cannot be obtained, performing hand ROI detection in a manner based on
skin color; S2, performing preliminary estimation in a hand three-dimensional global direction, wherein the S2 comprises the processes of S21, performing characteristic extracting; S22, realizing regression in the hand global direction according to a classifier R1; and S3, performing joint gesture estimation on the three-dimensional gesture, wherein the S3 comprises the processes of S31, realizing gesture estimation according to a classifier R2; and S32, performing gesture correction. According to the three-dimensional gesture estimation method and the three-dimensional gesture estimation
system, firstly cooperation of two manners is utilized for dividing hand ROI data; afterwards estimation in the hand global direction is finished according to a regression
algorithm based on hand ROI data dividing; and finally three-dimensional gesture estimation is realized by means of the regression
algorithm through utilizing the data as an aid. The three-dimensional gesture estimation method and the three-dimensional gesture estimation
system have advantages of
simple algorithm and high practical value.
