摘要： RGB-Z imaging systems acquire RGB data typically with a high X-Y resolution RGB pixel array, and acquire Z-depth data with an array of physically larger Z pixels having additive signal properties. In each acquired frame, RGB pixels are mapped to a corresponding Z pixel. Z image resolution is enhanced by identifying Z discontinuities and identifying corresponding RGB pixels where the Z discontinuities occur. Thus segmented data enables RGB background substitution, which preferably blends foreground pixel color and substitute background color. The segmented data also enables up-sampling in which a higher XY resolution Z image with accurate Z values is obtained. Up-sampling uses an equation set enabling assignment of accurate Z values to RGB pixels. Fixed acquisition frame rates are enabled by carefully culling bad Z data. Segmenting and up-sampling enhanced video effects and enable low cost, low Z resolution arrays to function comparably to higher quality, higher resolution Z arrays.
摘要翻译： RGB-Z成像系统通常采用高X-Y分辨率RGB像素阵列获取RGB数据，并采用具有加性信号特性的物理上较大的Z像素阵列获取Z深度数据。在每个获取的帧中，RGB像素被映射到相应的Z像素。通过识别Z不连续性并识别发生Z不连续性的相应RGB像素来增强Z图像分辨率。因此，分段数据可以进行RGB背景替换，其优选地将前景像素颜色和替代背景颜色混合。分段数据还可以进行上采样，其中获得具有精确Z值的较高XY分辨率Z图像。上采样使用能够将精确Z值分配给RGB像素的方程组。通过仔细剔除不良Z数据可以实现固定采集帧速率。分段和上采样增强的视频效果，并使低成本，低Z分辨率阵列能够与更高质量，更高分辨率的Z阵列相比较。
