digital_cam_pwm
Trigger using pwm cameras like MAPIR (https://www.mapir.camera/en-gb) or ThermalCapture 2.0 from TeAx (https://thermalcapture.com/thermalcapture-2-0/) **** MAPIR **** Duty cycle == 2000us : TRIGGER_ON Duty cycle == 1500us : SD Unmount Duty cycle == 1000us : TRIGGER_OFF Image capture frequency : 1.5s for JPG and 2.5-3.0s RAW+JPG The quickest the 2000us command should be sent is about once every 1.5s as the camera cannot capture JPG images more quickly than 1.5s. For RAW+JPG mode we recommend a 2.5-3.0s wait time. RAW images are used for capturing data for reflectance measurements, otherwise the pixels in the JPG are not usable. im_freq_timer should therefore be superior 1.5s (TRIGGER_CAMERA_CAPTURE_IMAGE_PERIOD = 1.5 seconds) NMEA GPS data are stored in metadata **** ThermalCapture **** Duty cycle inferior 1500us : TRIGGER_OFF Duty cycle superior 1500us : TRIGGER_ON Image capture frequency up to 30 Hz Possibility to capture one frame per trigger in configurator : Trigger frame mode Convert 14-bit data into temperature values : High gain mode: temp [°C] = raw * 0.04 - 273.15 Low gain mode : temp [°C] = raw * 0.4 - 273.15 NMEA GPS data are stored in metadata
