Streams

Each camera contains a number of sensors of different types. Each sensor (or combination of multiple sensors) provides an image stream which can be consumed directly as video stream, or fed as input into a neural network. Our API exposes operations through which these streams can be consumed or manipulated. Each stream is addresses either by its sensor name - CAM_(A-H) or by its combined name - DEPTH_(A-H)_(A-H).

Depth API

Some camera models containing multiple image sensors, support a feature called Stereo Depth. This feature combines data from two image sensors at a time, to calculate the depth of the image in front of it. The result is a single image stream. The image will consist of depth data calculated by the camera, lighter areas will contain objects that are closer to the camera while darker areas will contain objects further away. This stream is configurable the same way as a single sensor.

Depth stream and the respective sensors it uses cannot be both active at the same time. E.g. if stream DEPTH_B_C is active, then streams CAM_B and CAM_C will be inactive and vice versa.
