1. Purpose:
Using Android or HarmonyOS system to take photos of mobile phones, high-precision and ultra fast automatic counting of shrimp fry, crab fry, fish fry, fish eggs, microscopic images of granular purebred algae, etc. with black features.

2. Principle of Counting Analysis:
Place shrimp fry, crab fry, fish fry, etc. in a white rectangular dish with about 200 milliliters of water using a small mesh bag, and evenly disperse them,Avoid overlapAdjust the field of view of the phone, start the automatic seedling selection app on the phone, click on the phone to take photos and count, accurately select all shrimp seedlings, crab seedlings, fish fry, fish eggs, microscopic images of granular pure algae, etc. in the photo (the selected seedlings are automatically marked with colored dots and circles), and the time for one automatic recognition point operation is ≤ 10 seconds.

3. Main performance indicators:

• Shrimp fry and crab fry size: 6-15mm; fish fry size: 10-30mm; fish eggs size: 2-20mm
• Photo shrimp fry quantity: 3000-4000 per time (crab fry and fish fry quantity: 300-3000 per time, fish egg quantity: 3000-10000 per time)
• Shrimp fry automatic counting speed: 3000-10000 per minute
• The automatic counting error of shrimp fry, crab fry, fish fry, and fish eggs is ≤± 3%, and after a small amount of correction, it can be 100% correct
• The point counting results can be output to an EXCEL table, and the seedling marking chart can be saved
