Ensure the testing environment is nearly lightless, with an illuminance below 10 lux. (It is recommended that teams conduct the test indoors at night with the lights off and curtains closed.)<o:p></o:p>

Launch the Blackmagic Camera app or the native camera app, and switch to the Pro mode.<o:p></o:p>

3<o:p></o:p>

Go to camera settings:
1. For Xiaomi 14: lens: 23 mm; shutter: 1/1000s; FPS: 60; white balance: 6800k; tint: 25; ISO: 1600<o:p></o:p>

2. For iPhone 15 Pro and iPhone15 Pro Max: Lens: 24 mm; shutter: 1/1000s; FPS: 60; white balance: 4500k; tint: 15; ISO: 400<o:p></o:p>

3. For HUAWEI Mate 60 Pro: lens: 24 mm; shutter: 1/1000s; aperture: F1.6; FPS: 60; white balance: 5000k; ISO: 100<o:p></o:p>

1. Set the radio frequency between 10 Hz and 20 Hz.<o:p></o:p>

2. Position the phone at a 1.0-1.4 m distance directly in front of the Speed Monitor Module’s light indicator and record a 3-second or longer video of continuously launched projectiles.<o:p></o:p>

5<o:p></o:p>

Manually capture images from the video recorded in step 4, following these requirements:<o:p></o:p>

1. Capture images in the middle of continuous projectile launching.<o:p></o:p>

2. Each image must include a projectile in flight, 10-30 cm from the muzzle.<o:p></o:p>

3. Do not capture images of the initial shot or the first shot following a launching interruption.<o:p></o:p>

6<o:p></o:p>

Run 17mmBulletTest.exe and follow the instructions for a 17 mm projectile brightness self-test.<o:p></o:p>

Note: Image filenames must not contain Chinese characters.<o:p></o:p>

7<o:p></o:p>

In the opened image, draw a bounding box around the 17 mm projectile. The bounding box should enclose the projectile as tightly as possible, and only one projectile should be within each bounding box.<o:p></o:p>

8<o:p></o:p>

Record the value provided by the software.<o:p></o:p>

9<o:p></o:p>

Repeat steps 5, 6, 7, and 8 until you have five projectile brightness values. Calculate the average of these five values, which represents the effective brightness value of projectiles exiting the muzzle.<o:p></o:p>

1. For iPhone 15 Pro and iPhone 15 Pro Max, a brightness value greater than 95 indicates the test is passed.<o:p></o:p>

2. For Xiaomi 14, a brightness value greater than 170 indicates the test is passed.<o:p></o:p>

3. For HUAWEI Mate 60 Pro, a brightness value greater than 130 indicates the test is passed.<o:p></o:p>
