  2. The above detection distance, recognition distance, and identification distance are estimated according
    to Johnson’s Criteria, taking pedestrians (1.8×0.5×0.3m) as the target. The temperature measuring
    distance is estimated by a non-point source blackbody with a diameter of 0.15m.
  3. The temperature correction here refers to the distance correction tables, which can be provided by our
    company. Customers can correct the accuracy of temperature measurement targets at a longer distance by
    other distance correction methods.

5. Functions

5.1. Software Resources

We provide the following software and software development resources:

  • Application software: demonstration software FalconApplication
  • Parameter calibration/correction and firmware upgrade tool on Windows: FalconDevelopTool
  • Linux/Windows USB/DVP/SPI SDK
  • Android USB/SPI SDK
  • RTOS DVP/SPI SDK

Developers can contact our technical support personnel to obtain the latest version of software development
materials.

NOTE: The module itself has no USB interface. When using the module on Windows or using the USB SDK, please connect the development board with a DVP-to-USB converter.

5.2. Sequencing and Control

The device control interface adopts standard I2C. The maximum clock frequency is 400KHz, complies with the CCI
protocol in MIPI CSI-2, and the 7bit I2C address is 0111100b (0x3C).

The default output of the module is in “Image” Mode. Customers can switch to “Image + Temperature” Mode through
commands or switch to the “Raw Data” Mode if customized algorithm processing or image recognition is needed. Note
that “Imaging + Temperature” output at the same frame rate will double the data stream transmitted.

Table 5-1. Data format
Mode Data Type Data Format
Image Mode YUV422 256×192 / 160×120
Raw Data Mode Y14 / Y10 256×192 / 160×120
Temperature Mode Y14 256×192 / 160×120
Image + Temperature Mode YUV422 + Y14 256×384 / 160×240

DVP Mode

  • Support internal coding synchronization signal and external field synchronization signal.
  • 8-bit wide parallel port transmission.

DVP external synchronization

Figure 5-1. DVP external synchronization

VoSPI (Video Out SPI Interface) Mode

The VoSPI (Video out SPI interface) uses Motorola’s Serial Peripheral Interface (SPI) and its 4 lines interface
protocol. VoSPI defines two commands for reading data:

  1. Reading a new data frame.
  2. Continuing reading the current data frame.

The command to read a new data frame is used for SPI master to obtain a new image from RS001. When a frame of image
is too long to be transmitted at one time, it will continue reading the current frame for the continuation of the
previous “reading a new frame of image”.
