FPV热像仪如何修改色彩变焦

We offer two methods for modifying the color and zoom settings on the FPV thermal imaging camera.

1. Via the keypad serial port board parameter configuration board. Vcan2023-tool.
   • Click the Mode (飞涨) 按钮 once to change the color of the thermal imaging camera.
   • Click the Mode (飞涨) 按钮 twice to change the zoom in or out in 1x 2x 4x of the thermal imaging camera.
2. Via the UART AT commands. Please read this port.

This method applies to the following FPV thermal imaging cameras.

2. Communication method

2.1. Serial communication format

与主机建立通信之前, the communication parameters need to be set on the host according to the following table.

Data transfer communication example

This example is “Set the current color to Fusion 1 模式”。 

步 1 Query the device address command, class command address, subclass command address, and read-write flag.

Query the serial port command table in Appendix A to obtain the device address command(0x36) and the class command address (0x78), subclass command address (0x20), and flag bit (写: 0x00).

步 2 Calculate SIZE, 数据, and CHK values. 

尺寸: N+4. The color setting is N=1 and SIZE is 0x05. 

数据: Color fusion mode, corresponding hexadecimal value is 0x02.

CHK: The fields are 0x36, 0x78, 0x02, 0x00 and 0x02. After accumulation, the result of taking the lower 8 bits is 0XD0. 

It can be calculated using the calculator that comes with your PC. 

Combined with the above parameters, the host sends the command F0 05 36 78 20 00 02 D0 FF to the camera.

Communication receiving the data packet

 In the command format returned by the thermal imaging core to the host, DATA0 is the high byte, and DATA (N-1) is the low byte.

Color Settings

Thermal imaging is based on infrared radiation intensity and has no color information. The image algorithm maps a set of colors based on the grayscale value, namely pseudo color. The camera supports multiple pseudo-color modes for users to choose from. The default is white hot 0x00.

Commands and parameters

Set the pseudo-color type displayed by the camera:

Command Direction	尺寸	设备地址	Class Command Address	0x00: 白热 0x01: 黑热 0x02: 融合 1 0x03: 彩虹 0x04: 融合 2 0x05: 铁红 1 0x06: 铁红 2 0x07: 深棕色 0x08: 颜色 1 0x09: 颜色 2 0x0A: Ice Fire 0x0B: 雨 0x0C: 绿色热力 0x0D: 红热 0x0E: 深蓝色	Flag bit	数据	CHK
