[An antennal electric signal detection system based on template matching]

Area of Science:

• Biomimetic sensor technology
• Insect sensory perception mechanisms
• Neuroethology

Background:

• Insect antennae are highly efficient natural sensors.
• Current antenna perception studies face challenges with standardization and efficiency.
• Manual operations introduce variability and reduce experimental throughput.

Purpose of the Study:

• To develop an automated experimental device for collecting insect antenna electrical signals.
• To standardize the experimental process for studying antenna perception mechanisms.
• To accurately measure antenna reaction times in response to stimuli.

Main Methods:

• Established image templates for automatic insect head identification and localization using Hausdorff template matching.
• Developed a method to calculate insect head angle deviation based on the minimum external rectangle.
• Utilized an electrical signal acquisition device to record antennal responses to chemical reagents.

Main Results:

• Achieved 95.3% accuracy in locating honeybee heads with minimal angle deviation (<1°).
• Ensured consistent and appropriate distance between antennae and experimental reagents.
• Collected honeybee antenna contact reaction times to sucrose solution, consistent with manual experiments.

Conclusions:

• The automated system effectively collects undisturbed antenna contact signals.
• Standardization of experiments on antenna perception mechanisms is realized.
• Provides a reliable experimental method and device for studying biological antenna perception and reaction times.
