US12768620 - Telescope range finder based on thermal image-wind speed-noise and ranging method thereof
Provided is a telescope range finder based on thermal image-wind speed-noise, which includes a range finder body, a wind speed measuring device, a noise measuring device, and a thermal image display device. The range finder body includes a processor. The wind speed measuring device includes a wind wheel, the wind wheel is connected to a tachometer, and the tachometer is connected to the processor. The noise measuring device includes a microphone, and the microphone is connected to an amplification-filtering-rectification circuit. The amplification-filtering-rectification circuit is connected to the processor. The microphone is configured to convert a noise into an electrical signal for entering the processor through the amplification-filtering-rectification circuit. The thermal image display device includes a thermal image sensor. The thermal image sensor is disposed in the range finder body. The thermal image sensor is connected to a display through the processor.
