The camera described here makes color TV images that include information about the distance between the camera and the objects in the images. This range information is obtained from two images of the same scene taken under different illumination conditions. The camera does not require scanning, multiple camera units, or complicated computation. Range information for each pixel is acquired fast enough to keep up with the video rate of a TV camera. We describe various operational features and technical specifications such as ranging errors as well as the results of experimental investigations of the dependence on the color and reflectivity of the objects, of the sensitivity to interference from external light, and of the effects of the movement of the objects.
这里所描述的相机能够生成彩色电视图像，这些图像包含了相机与图像中物体之间距离的信息。该距离信息是通过在不同光照条件下拍摄的同一场景的两幅图像获得的。该相机不需要扫描、多个相机单元或复杂的计算。每个像素的距离信息获取速度足够快，能够跟上电视摄像机的视频速率。我们描述了各种操作特性和技术规格，如测距误差，以及关于物体颜色和反射率的依赖性、对外部光干扰的敏感性和物体运动影响的实验研究结果。
