Embodiment Construction
[0093] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0094] figure 1 It is a schematic diagram of a motion capture system provided by an embodiment of the present invention. The motion capture system may include multiple image acquisition devices 101 and computer devices 102 , and may also include a synchronization generator 103 .
[0095] Wherein, the image acquisition device 101 is used for image acquisition of multiple objects, and the multiple objects may be reflective balls installed on various moving objects, such as infrared reflective balls. A sphere that strongly reflects infrared light. The image acquisition device 101 is also used to process the acquired images, obtain two-dimensional position information (such as two-dimensional coordinates) of multiple targets imaged in each of th...

The invention discloses a motion capture method, device and system, belonging to the technical field of computers. The method includes: acquiring two-dimensional position information of a plurality of targets imaged in each image collected by a plurality of image acquisition devices at the current moment; Know the predicted three-dimensional position information of the target at the current moment; convert the predicted three-dimensional position information of the known target at the current moment into the predicted two-dimensional position information based on the parameter information of multiple image acquisition devices; convert the predicted two-dimensional position information with the predicted two-dimensional position information The two-dimensional position information of each image in each image is corresponding to determine the two-dimensional position information of the known target imaged in each image; the two-dimensional position information of the known target imaged in each image is converted into a known target The three-dimensional position information of the object at the current moment. The invention can improve the accuracy of the system capturing the target.
Description
technical field [0001] The present invention relates to the field of computer technology, and in particular, to a motion capture method, device and system. Background technique [0002] With the development of computer technology, motion capture technology is becoming more and more mature. Motion capture technology is based on the principle of computer graphics to obtain the motion status of moving objects at different times, so as to achieve the purpose of positioning and tracking running objects. [0003] At present, the motion capture method used in the related art is as follows: first, the color component model [R, G, B] of the moving object is extracted by taking the average value of multiple shots, and then each camera is used to collect images of the moving object to obtain There are multiple images to be recognized that contain moving objects. For each image, traverse the color components [Rp, Gp, Bp] of each pixel in the image, and each time a pixel is traversed, de...
