1. Understanding the Importance of Sensor Size in Autel EVO Cameras

The sensor size of any camera, including those found in Autel EVO drones, significantly impacts the quality of images and videos produced. A larger sensor generally captures more light, resulting in better dynamic range, improved low-light performance, and reduced noise. This is particularly crucial in professional applications such as aerial photography, surveying, and inspection where clarity and detail are paramount. With a clear understanding of sensor dimensions and their implications, users can optimize their drone settings and capture higher-quality data.

1.1. What is Sensor Size?

Sensor size refers to the physical dimensions of the image sensor in a camera, typically measured in millimeters. The sensor is the component that captures light and converts it into an electronic signal to form an image. Common sensor sizes include full-frame, APS-C, and smaller formats found in smartphones and drones. The larger the sensor, the more light it can capture, leading to improved image quality.

The EVO II Pro 6K, with its larger 2.4μm pixels, excels in low-light conditions compared to the EVO II 8K, which has smaller 0.8μm pixels but higher resolution.

4. Calculating Ground Sample Distance (GSD)

Ground Sample Distance (GSD) is a crucial metric in aerial surveying and mapping, indicating the size of one pixel on the ground. Accurate GSD calculation ensures precise data collection and analysis.

4.1. What is Ground Sample Distance (GSD)?

Ground Sample Distance (GSD) represents the physical distance on the ground that each pixel in an aerial image covers. It is typically measured in centimeters per pixel (cm/pixel) or inches per pixel (in/pixel). A smaller GSD value indicates higher resolution and more detailed imagery.

4.2. Formula for Calculating GSD

The formula for calculating GSD is:

GSD = (Sensor Width * Flight Altitude) / (Focal Length * Image Width)

Where:

Sensor Width is the physical width of the camera sensor in millimeters.
Flight Altitude is the height of the drone above the ground in millimeters.
Focal Length is the focal length of the camera lens in millimeters.
Image Width is the width of the image in pixels.

4.3. Practical Example: Calculating GSD for EVO II Pro 6K

Let’s calculate the GSD for an Autel EVO II Pro 6K flying at an altitude of 100 meters (100,000 mm).

Sensor Width: 13.2 mm (approximate for a 1-inch sensor)
Flight Altitude: 100,000 mm
Focal Length: 28 mm
Image Width: 5472 pixels

GSD = (13.2 mm * 100,000 mm) / (28 mm * 5472 pixels)
GSD ≈ 8.6 cm/pixel

This means each pixel in the image covers approximately 8.6 cm on the ground.

4.4. Factors Affecting GSD

Several factors can influence GSD:

Flight Altitude: Higher altitudes increase GSD, reducing image resolution.
Focal Length: Longer focal lengths decrease GSD, increasing image resolution.
Sensor Size: Larger sensors generally allow for lower GSD values at the same altitude and focal length.

4.5. Optimizing GSD for Specific Applications

Surveying and Mapping: Aim for a GSD of 5 cm/pixel or lower for highly accurate measurements.
Inspections: A GSD of 2 cm/pixel or lower is recommended for detailed visual inspections.
Aerial Photography: GSD can be less critical, but lower values improve overall image quality and detail.

5. Formulas for Understanding Camera Performance

Understanding various formulas related to camera performance helps optimize image quality and data accuracy.

5.1. Crop Factor

Crop factor is the ratio of a full-frame sensor size to the sensor size of a smaller camera. It affects the effective focal length and field of view.

Crop Factor = 35mm / Digital Sensor Width

5.2. True Focal Length

True focal length is the actual focal length of the lens, which can be calculated using the crop factor.

True Focal Length = 35mm Equivalent Focal Length / Crop Factor

5.3. Motion Blur

Motion blur occurs when the camera or subject moves during exposure. It can be calculated as:

Motion Blur = Camera Shutter Interval (s) * Drone Speed (m/s)

5.4. Optimal Flight Speed

Optimal flight speed ensures sufficient overlap between images for photogrammetry.

Optimal Flight Speed = Image Interval / Camera Interval

5.5. Sensor Width Calculation

Sensor width can be calculated using the focal length and horizontal field of view (FOV).

Sensor Width = 2 * (Focal Length * TAN((0.5 * Horz Field of View) / 57.296))

6. Optimizing Camera Settings for Different Scenarios
