Embodiment Construction

[0120] A head posture detection method based on RGB-D images, the method steps are as follows: (1), collect head posture depth images and RGB images, and align the head posture depth images and RGB images to obtain head posture attitude image; (2), point cloud calculation is performed on the head attitude image aligned in step (1) to obtain the point cloud data of the head to be detected; (3), the point cloud data in step (2) is substituted into the three-dimensional standard head The body model is registered with the 3D standard head model point cloud to complete the head pose detection.

[0121] (1) The depth image in the step is obtained by the 3D depth imaging module in the Intel RealSense SR300 camera, that is, the depth camera, which is a grayscale image reflecting the distance from the imaging object to the optical center of the depth camera; the color image is an RGB image, due to The 2D color imaging module in the Tel RealSense SR300 camera, that is, the color camera....

Abstract

The invention discloses a head posture detection method based on an RGB-D image, and the method comprises the following steps: (1) collecting a head posture depth image and an RGB image, and aligningthe head posture depth image and the RGB image to obtain a head posture image; (2) carrying out point cloud calculation on the head posture images aligned in the step (1) to obtain to-be-detected headpoint cloud data; and (3) substituting the point cloud data in the step (2) into the three-dimensional standard head model to be registered with the point cloud of the three-dimensional standard headmodel to complete head posture detection. According to the algorithm, the human head posture can be accurately detected in a diagnosis and treatment room environment with a uniform and sufficient light source, and the posture estimation robustness when the head posture angle is large is improved.
