We have developed a field-worthy, high-definition, real-time depth-mapping television camera called the HDTV Axi-Vision Camera. The camera can simultaneously capture both an ordinary HDTV color image and a depth image of objects on more than 1280 x 720 pixels at a frame rate of 29.97 Hz, or on 853 x 480 pixels at a frame rate of 59.94 Hz. The number of detectable pixels per unit time was increased by about 5 times that of the prototype camera by improving the sensitivity and resolution of the depthmapping camera. Short video clips demonstrate how depth information from the camera can be used to create a virtual image in actual television program production.
我们开发了一款适用于现场的高清实时深度映射电视摄像机，称为高清电视Axi-Vision摄像机。该摄像机能够同时捕捉普通的高清电视彩色图像以及物体的深度图像，在29.97赫兹的帧率下，图像分辨率超过1280×720像素；在59.94赫兹的帧率下，图像分辨率为853×480像素。通过提高深度映射摄像机的灵敏度和分辨率，每单位时间可检测的像素数量比原型摄像机增加了约5倍。短视频片段展示了如何在实际电视节目制作中利用该摄像机的深度信息来创建虚拟图像。
