On the side that target frame is equipped with laser sensor, the liquid crystal display and N number of laser sensor by electric interfaces respectively with
Central processing unit connection, central processing unit and liquid crystal display connect to power supply respectively, and target frame is fixed on bracket.
A kind of test method based on full-automatic Nutation Angle testing laser target, method and step are as follows:
Step 1 builds full-automatic Nutation Angle testing laser target.
Step 2 opens power supply.
Step 3, bullet pass through target frame when, N number of laser sensor test automatically respectively its between bullet reflecting surface away from
From, and it is sent into central processing unit.
The distance of laser sensor is converted complete virtual shell hole by step 4, central processing unit, and calculates the height of bullet
The angle of attack and the direction angle of attack, and current time is recorded, and above- mentioned information are sent into liquid crystal display.
Step 5, crystal display show the high low angle of attack of calculating of central processing unit, the direction angle of attack and record it is current when
Between.
In step 4, the distance of laser sensor is converted complete virtual shell hole by central processing unit, and the specific method is as follows:
