From each accessory weight and its arm about the gimbal axis, positive ahead of the lens and negative behind it, computes the combined centre of gravity and checks moment balance.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Center of gravity | r_c = Σ(mᵢrᵢ)/Σmᵢ | Classical mechanics |
| Moment balance | Σ(mᵢg·dᵢ)=0 for balance | Static equilibrium |
| Gimbal balancing | Coincide CG with gimbal axes | Gimbal tuning guide |
| Gimbal torque | τ = m·g·d offset distance | Mechatronic design |
| Motor sizing | Rated ≥1.5× max static torque | Servo sizing practice |
| Inertia effect | J = Σmᵢrᵢ² moment of inertia | Rigid body dynamics |
云台相机重心计算器基于力矩平衡原理，输入相机机身、镜头、配重、附件等部件的重量与距云台轴的力臂，计算合成重心位置与各部件力矩，并给出配重方案建议，帮助实现云台静平衡。
