The test platform (right picture) can also perform rotation by the vertical axis (stepper motor, bipolar, 24V, 0.5A). Since there is no slip ring for USB cameras' data transfer, the expected yaw angle is ±230-270° (some experiments required), the horizontal rotation angle is -85°..+110° (0° - horizontal line).
All my control boards are designed for a closed loop control (feedback angle is measured by optical sensor and corrections applied after each motor step if required). The pitch rotation motor does not have a secondary shaft, so the feedback wheel will be mounted on a plate's output shaft and a sensor will be mounted from the side. Bottom motor has a secondary shaft, so encoder wheel is mounted thru the special shaft coupling (on picture below the wheel is not yet installed).
I will describe a sensor system in details in next posts, when demonstrating a camera movement control and a video capture. Below there is a mounting place for a sensor (optical interrupter TCST1103/1202).
I'm planning to publish here run tests of my application (OpenCV+Qt) for image capture and disparity map generation within 4 weeks.
Currently I'm busy on programming (upgrading) my parallel neural network application (also using GPU /w OpenCL). I will post results and an application here about it within two weeks.
