We describe a novel real-time depth-mapping camera, the Gainmodulated Axi-Vision Camera, where pulsed laser light is combined with a gain-modulated camera. Depth resolution of 2.4 mm was obtained, which is higher than the resolution of the previously reported depth-mapping Axi- Vision Camera. Pixel-by-pixel depth information of 768 x 493 pixels is obtainable at one half of the video frame rate (15 Hz). A short movie clip is attached that illustrates the depth measurement operation. The merits of the Gain-modulated Axi-Vision Camera are high-resolution, real-time operation, and a relatively simple optical system. These merits primarily arise from the ultra-fast exposure time using a pulsed laser diode.
我们介绍了一种新型的实时深度映射相机——增益调制轴视相机，它将脉冲激光与增益调制相机相结合。获得了2.4毫米的深度分辨率，高于先前报道的深度映射轴视相机的分辨率。在视频帧率的一半（15赫兹）下可获得768×493像素的逐像素深度信息。附件中有一个短片展示了深度测量操作。增益调制轴视相机的优点是高分辨率、实时操作以及光学系统相对简单。这些优点主要源于使用脉冲激光二极管的超快速曝光时间。
