Embodiment Construction

[0072] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0073] The overall method of the embodiment of the present invention is that the human body turns around facing the depth camera device, and collects a sequence of depth images including the torso. The depth image sequence is spliced ​​to form a point cloud data of the torso, and the body measurements are measured according to the point cloud data.

[0074] figure 1 It is a method flowchart of the method for measuring the circumference of a human body trunk in an embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps.

[0075] Step 100. Acquire three-dimensional torso point cloud data, the three-dimensional torso point cloud data reflecting the spatial coordinates of all sampling points on the human torso surface.

[0076] Wherein, the point cloud...

Abstract

The invention discloses a human body torso girth measurement method and a device based on computer visual sense. Human body torso depth image sequences are obtained through the human body surrounding shooting via a depth camera device, human body torso three-dimensional point cloud data is obtained through human body posture identification division and point cloud registration split joint, torso profile images are obtained through re-projection of the torso three-dimensional point cloud data, and in addition, the human body torso girth is calculated according to the profile images. The precision of the torso measurement value obtained according to the method and the device provided by the invention is high, the batch data processing by measuring personnel is convenient, and the automation degree and the efficiency of the human body contour data measurement are greatly improved.

Description

technical field [0001] The invention relates to computer vision technology, in particular to a method and device for measuring the circumference of a human body based on computer vision. Background technique [0002] With the development of Internet and image processing technology, it is necessary to obtain the body shape parameters in many applications such as games, human-computer interaction, security, telepresence and health care. Human trunk circumference, such as chest circumference, waist circumference and hip circumference, are important body shape parameters of the human body. The traditional way of measuring the circumference of the torso requires the subject to go to the physical examination site to measure with a ruler or optical equipment. This traditional measurement method is inefficient and requires on-site operations and records by surveyors, and cannot perform batch measurement of human torso circumference. Especially when performing human body modeling, ...
