Infrared Thermal Camera
What are the differences between the three gain modes of Zenmuse H30T? What application scenarios do they correspond to?
High Gain mode offers more precise temperature measurement capabilities, with a measurement range of -20° to 150° C (-4° to 302° F).
Low Gain mode provides a broader temperature measurement range, from 0° to 600° C (32° to 1112° F).
High-Res mode is designed for observing objects with small temperature differences, making the subject stand out more clearly. Temperature measurement is not supported in this mode.
How many ways can I measure temperature using Zenmuse H30T?
Spot Measurement: Tap on any spot in the infrared thermal camera view to display the temperature of that spot.
Center Point Temperature Measurement: Tap on the center point in the infrared thermal camera view to display the temperature at that point for higher-precision measurements. Tapping outside the center point exits the Center Point Temperature Measurement mode.
Area Measurement: Frame to select any area in the infrared thermal camera view to display the highest and lowest temperatures within that area, along with their locations.
What is Flat-Field Calibration (FFC) in Zenmuse H30T?
Flat-Field Calibration is used to optimize thermal image quality so temperature changes can be observed more easily. You can choose to manually enable FFC by turning off the automatic FFC adjustment in settings.
Why does the image exhibit uneven dark or bright areas after performing manual FFC multiple times in succession?
It is not recommended to continuously perform manual FFC without pause, as this can cause the infrared thermal camera's shutter to heat unevenly, resulting in an inconsistent image. If this occurs, perform an FFC once every 30 seconds, and the image should return to normal.
What is the temperature measurement accuracy of Zenmuse H30T?
In a windless 25°C (77°F) laboratory environment, observing a blackbody subject from a distance of 13 meters:
Without the Infrared Density Filter installed, the measurement accuracy in High Gain mode is ±2° C or ±2%, and in Low Gain mode, it is ±5° C or ±3% (whichever is greater).
With the Infrared Density Filter installed, the measurement accuracy for temperatures = 1000° C (1832° F) is ±80° C (176° F) or ±8%; for temperatures > 1000° C (1832° F), it is ±100° C (212° F) or ±10% (whichever is greater).
What is the focusing distance of the infrared thermal camera on Zenmuse H30T? Does the focusing distance affect the accuracy of temperature measurements?
The minimum focusing distance is 13 meters. Within 13 meters, the temperature measurement accuracy is not affected, but the image will be out of focus. It is recommended to maintain a focusing distance of more than 13 meters.
What software can be used for post-processing of infrared thermal imaging photos taken by Zenmuse H30T?
You can use DTAT3 (DJI Thermal Analysis Tool 3) V3.3.0 or later.
Is the infrared resolution of 1280×1024 based on the original sensor size or from an algorithmic enhancement?
It is the native sensor size with a resolution of 1280×1024.
What is the function of Zenmuse H30T's UHR (Ultra-High Resolution) Infrared Image?
This feature allows the capture of clear images when the infrared thermal camera is at 5× zoom or higher.
What factors can affect the temperature measurement accuracy of the Zenmuse H30T's infrared thermal camera?
Factors such as the subject's emissivity, distance, environmental temperature, and humidity can impact the accuracy of temperature measurements.
How do I set the infrared temperature measurement parameters for Zenmuse H30T?
Infrared temperature measurement parameters can be set in the DJI Pilot 2 app. The app supports automatic reading of laser rangefinding and environmental temperature values, as well as manual setting of object emissivity and environmental humidity values to correct the temperature measurement results.
What is the main strategy for the Zenmuse H30T's sensor burn protection feature?
H30T will automatically close the shutter when it detects conditions that could cause burns to the infrared sensor. However, software detection may fail. Do not aim the lens of the infrared thermal camera at high-energy power sources, such as the sun, lava, or laser beams. Otherwise, it will burn the camera and cause irreversible damage.
What is the Zenmuse H30T's Infrared Density Filter for?
It extends the thermal imaging module's temperature measurement range to 0° to 1600° C (32° to 2912° F), allowing for more effective temperature variation assessment and rapid locating of high-temperature points. After installing the Infrared Density Filter, there is a reduction in IR signal reception, which also degrades image quality. It is not suitable for observing subjects at normal temperatures and is recommended for use in Low Gain mode.
Visible Light Camera
What is the Night Scene mode of the Zenmuse H30 Series?
It enhances image quality in low-light conditions, presenting clearer and more accurate visual information to ensure efficiency and precision during nighttime operations.
How has the Night Scene mode improved in H30T compared to H20N?
H30T's Night Scene mode supports adjustments of 25fps, 15fps, and 5fps, with a maximum ISO of 819,200, offering better noise reduction and support for NIR illumination.
In the Night Scene mode, why does a higher noise reduction level decrease the smoothness of live feeds?
Higher noise reduction levels result in lower frame rates, longer exposure times, and higher sensitivity, along with stronger noise reduction performance. However, due to the reduced frame rate, the smoothness of the live feed is correspondingly decreased.
What is the function of electronic dehazing of the Zenmuse H30 Series, and how do I choose the intensity of dehazing?
Electronic dehazing is an image-processing technique designed to reduce image blurring and haze effects caused by light scattering, atmospheric humidity, and other factors. It uses computer algorithms to optimize and restore images, enhancing their clarity and quality. Low-level electronic dehazing is mainly for mild haze conditions, while high-level electronic dehazing can handle situations like post-rain fog and moderate haze.
Can I enable electronic dehazing in the Night Scene mode?
No. Electronic dehazing is intended for daytime haze scenarios, while the Night Scene mode is for low-light conditions at night. Both require image processing, but due to different application scenarios and purposes, their effects would conflict, hence they are not supported simultaneously.
Why is electronic dehazing only supported by the zoom camera?
Zoom cameras typically observe subjects that are farther away and are more susceptible to the effects of rain, fog, and haze in the air. Therefore, electronic dehazing is primarily provided for the zoom camera.
What is the maximum zoom supported by the zoom camera when performing High-Res Grid Photo?
It supports up to 15× zoom.
What is the Smart Capture mode, and what are its main application scenarios?
Smart Capture mode allows the camera to automatically adjust parameters based on different scenes and lighting conditions to achieve higher-quality photo results. However, the shooting speed may be slower compared to Single Shot mode. Smart Capture is suitable for all scenarios.
What is the surveying and mapping accuracy of the Zenmuse H30 Series?
H30 series supports general surveying and mapping with an accuracy of = 10 cm.*
* Measured under the following conditions in a DJI laboratory environment: Zenmuse H30 mounted on a Matrice 350 RTK and powered up. Using DJI Pilot 2’s Area Route to plan the flight route. RTK in the FIX status.
The relative altitude was set to 80 m, flight speed to 10 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1500 m. The field contained objects with obvious angular features, and used exposed hard-ground checkpoints that conformed to the diffuse reflection model. Post-processing with DJI Terra achieved a horizontal accuracy of 10 cm.
What is the minimum focusing distance of the visible light cameras of the Zenmuse H30 Series?
For the zoom camera, the minimum focusing distance is 1.5 meters below 5× zoom, 5 meters between 5× and 20×, and 10 meters above 20× zoom. The wide-angle camera has a minimum focusing distance of 1 meter.
What is the IR Light feature of Zenmuse H30T, and what are its use scenarios?
It switches the live feed to a grayscale image by removing the IR filter, thereby strengthening the contrast between light and dark areas, making it easier to locate subjects.
IR Light is supported only when using the zoom camera.
NIR Auxiliary Light
What is the function of the NIR auxiliary light of the DJI Zenmuse H30 Series?
The NIR auxiliary light provides additional NIR illumination in low-light environments (less than 1 lux, half moon), enhancing covert night surveillance and search-and-rescue operations.
NIR Auxiliary Light is supported only when using the zoom camera and only after the aircraft has taken off. If the NIR Auxiliary Light is enabled first, IR Light will also start simultaneously.
What are the limitations of the NIR auxiliary light on the DJI Zenmuse H30 Series?
1. In low-light/dark environments (e.g., urban areas at night), the Night Scene mode is sufficient. It is not recommended to activate the NIR Auxiliary Light in these conditions, as it may cause image whitening and reduced contrast.
2. When observing at distances beyond 200 meters in low-light/dark conditions or in weather conditions like rain or fog, the backward scattering of light due to the Tyndall effect from particles in the air can lead to image whitening and reduced contrast.
Laser Range Finder
What is the measurement range of the laser range finder of the DJI Zenmuse H30 Series? What is the blind zone?
The range is 3-3000 m, with the upper limit of the measurement distance being 3000 meters and the lower limit being 3 meters.
Range for common objects: grasslands 2000 m, woodlands 1900 m, road surfaces 1700 m.*
Data measured in a DJI laboratory. The rangefinding data may vary based on the material and shape of the tested object as well as the impact of gimbal angle, environmental light, and weather conditions such as rain or fog. If a laser pulse hits multiple targets, its energy is dispersed, which may reduce the measurable distance.
* Test conditions: Flat surface subject, subject size exceeding the laser beam diameter, atmospheric visibility of 23 km (shorter range in clear conditions compared with overcast), laser impinges at an oblique angle (with an angle of incidence of approx. 0.2 radians).
What are the challenging scenarios for the laser range finder of the DJI Zenmuse H30 Series?
1. Weather conditions such as rain, fog, haze, or snow.
2. Specular reflective objects and total reflective objects.
