Hardware Preparation

• 3D ToF Depth Sensor Camera (SKU:SEN0581), Quantity:1, Purchase Link: https://www.dfrobot.com/product-2741.html
• USB-TTL module (optional), Quantity:1, Purchase Link: (not provided in original)
• Type-C cable, Quantity:1, Purchase Link: (not provided in original)

Software Preparation

• Windows system:comtool-windows
• Linux system:https://github.com/sipeed/MetaSense-ComTool

Open the COMTOOL software and select the Graph interface. If there is no Graph above the software, you can add a Graph at the + sign in the upper right corner. If the middle part is blank after creation, double-click MaixSenseLite in the lower left corner

Select a small Port and baud rate in the left port (choose any high baud rate), click open and check USB to receive a large amount of data. Connected will be displayed in the lower left corner

Set the Header to \x00\xFF to correctly parse the image data and observe the depth map to intuitively feel the depth on the 2D flat image.

Comtool configuration instructions

Comtool configuration control description of the host computer

• Header:et the identification header.
• RawCMD:User can send commands manually (USB and UART serial ports behave the same).
• ISP:start stop.
• LCD:display the lcd screen on and off.
• USB:serial port transmission depth map on and off.
• UART:serial port transmission depth map on and off.
• ANTIMMI:Automatic anti-multi-machine interference is turned on and off (susceptible to interference, the effect of turning off is better)
• Binn:pull down to set BINNING, Baud to set UART baud rate.
• X, Y:coordinates:When the checkbox to the left of D is on, the (x,y) distance from the camera is displayed.
• Unit:sets the quantization unit:16-bit quantization to 8-bit, the scale is reduced, if the setting is too small, only very close images can be seen clearly.
• FPS:Set the output frame rate (it should not be too high, set it reasonably according to the performance of the docking device, reducing the frame rate can reduce the amount of transmitted data)
• Ev:Exposure gap control (leftmost represents AE, others are fixed exposure time)
