Abstract

The invention discloses a frame synchronization method of image data and a camera. The method of the present invention comprises: acquiring a color image data stream and a depth image data stream transmitted by different signal channels; wherein a color image frame in the color image data stream and a depth image frame in the depth image data stream comprise synchronous frames which are synchronously output after exposure of a color camera and a depth camera; wherein the transmission delays of the different signal channels are different, and the data volume structures of the color image frameand the depth image frame carry timestamps and exposure time; obtaining the SOF time of the color image frame and the SOF time of the depth image frame respectively according to the timestamp and theexposure time; and acquiring a synchronous frame image from the color image data stream and the depth image data stream according to the SOF time. According to the invention, image data asynchronization caused by transmission delay can be avoided, and it is ensured that an upper layer obtains a synchronous color image and a depth image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a frame synchronization method of image data and a camera. Background technique [0002] 3D bone recognition technology has been applied to many fields, such as various Meitugong software, which has bone recognition technology, which can accurately locate the position of human bones, so as to make partial adjustments to portraits and realize the function of beautifying the whole body. "Bone recognition point technology", also known as "limb detection technology", can use computer vision technology to estimate the position of human joint points from images or videos, and given an image containing the human body, it can accurately locate the position of each joint of the human body in the image , such as elbow joints, wrist joints, knee joints, etc., the positioned joint points can finally form a human skeleton map, which can reflect the current posture of the human body a...
