摘要： Techniques are provided for de-aliasing depth images. The depth image may have been generated based on phase differences between a transmitted and received modulated light beam. A method may include accessing a depth image that has a depth value for a plurality of locations in the depth image. Each location has one or more neighbor locations. Potential depth values are determined for each of the plurality of locations based on the depth value in the depth image for the location and potential aliasing in the depth image. A cost function is determined based on differences between the potential depth values of each location and its neighboring locations. Determining the cost function includes assigning a higher cost for greater differences in potential depth values between neighboring locations. The cost function is substantially minimized to select one of the potential depth values for each of the locations.
摘要翻译： 提供了去锯齿深度图像的技术。 可以基于发送和接收的调制光束之间的相位差来生成深度图像。 一种方法可以包括访问具有深度图像中的多个位置的深度值的深度图像。 每个位置都有一个或多个邻居位置。 基于深度图像中的深度图像中的深度值和深度图像中的潜在混叠，为每个多个位置确定潜在深度值。 基于每个位置的潜在深度值与其相邻位置之间的差异来确定成本函数。 确定成本函数包括为相邻位置之间的潜在深度值的更大差异分配更高的成本。 成本函数基本上被最小化以选择每个位置的潜在深度值之一。

摘要： Compatibility between a depth image consumer and a depth image producer is provided by receiving a native depth image having an unsupported type that is not supported by a depth image consumer, and processing the native depth image into an emulation depth image having a supported type that is supported by the depth image consumer. This emulation depth image is then output to the depth image consumer.

摘要： Compatibility between a depth image consumer and a plurality of different depth image producers is provided by receiving a native depth image having unsupported depth camera parameters that are not compatible with a depth image consumer, and converting the native depth image to a virtual depth image having supported virtual depth camera parameters that are compatible with the depth image consumer. This virtual depth image is then output to the depth image consumer.

摘要： An image camera component and its method of operation are disclosed. The image camera component detects when ambient light within a field of view of the camera component interferes with operation of the camera component to correctly identify distances to objects within the field of view of the camera component. Upon detecting a problematic ambient light source, the image camera component may cause an alert to be generated so that a user can ameliorate the problematic ambient light source.

摘要： A depth camera computing device is provided, including a depth camera and a data-holding subsystem holding instructions executable by a logic subsystem. The instructions are configured to receive a raw image from the depth camera, convert the raw image into a processed image according to a weighting function, and output the processed image. The weighing function is configured to vary test light intensity information generated by the depth camera from a native image collected by the depth camera from a calibration scene toward calibration light intensity information of a reference image collected by a high-precision test source from the calibration scene.
