---|---|
0 "DEFAULT UNIT" | The default quantization strategy is used. Due to the tof characteristic, the imaging accuracy at near distances is better than that at far distances. Therefore, the difference at short distances is enlarged, and 5.1*sqrt(x) is used to quantify the original data of 16 bits into 8 bits |
1...9 "QUANTIZE UNIT" | Represents quantization in x mm. The smaller the value, the more details and the shorter the visual distance. Please set it properly |

Image Packet Description
When power on, the ISP will be activated by default and display the image on the display screen, and output the image data to uart and usb at the same time
Image data encapsulated into packets (not stabilized):
- Header 2 bytes: 0X00, 0XFF
- Packet length 2 bytes: the number of bytes of remaining data in the current packet
- Other content 16 bytes: including packet serial number, packet length, resolution, etc.
- Image frame
- Check 1 byte: the lower eight bits of the "sum" of all previous bytes
- 1 byte at the end of the packet: 0XDD
