Embodiment Construction

[0052]In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0053] Following the description of the background technology, the brightness of the image captured by the motion capture camera is uneven. It should be noted that the uneven brightness of the image mentioned here refers to the uneven brightness of the images formed by at least two objects of the same type in the image with the same distance from the motion capture camera, the same type and differe...

Abstract

The invention discloses an image brightness adjusting method and device, which are used for adjusting the brightness of an image shot by a motion capture camera. The method comprises the following steps of dividing an image into a plurality of sub-image regions; calculating a gain compensation value corresponding to each sub-image region; and adjusting the gain of each sub-image region according to the calculated gain compensation value in order to make the brightness of images formed by homogeneous target objects in the plurality of sub-image regions consistent; wherein the brightness of thesame sub-image region is consistent. By the adoption of the technical scheme, a capture effect of the motion capture camera can be guaranteed, and a problem that some regions of the image are too bright or too dark is avoided.

Description

technical field [0001] The invention belongs to the technical field of optical motion capture, and in particular relates to an image brightness adjustment method and device. Background technique [0002] At present, when realizing the motion capture of an object, an optical motion capture camera is usually used to obtain the three-dimensional space position of the object. The existing optical motion capture mainly adopts a marker-type optical motion capture system, which includes: optical markers (Markers), a motion capture camera (hereinafter referred to as a motion capture camera), a signal transmission device, and a data processing center. When a moving object is pasted with Markers and moves, multiple motion capture cameras detect Marker points from different angles, and transmit the spatial position information of the detected Marker points to the data processing center in real time through signal transmission equipment. The data processing center calculates the spatia...
