基于BLOB跟踪算法的老年群体安全疏散时间预测

Prediction of safe evacuation time of elderly group based on BOLB tracking algorithm

安全疏散设计是建筑防火设计的一项重要内容,而老年人群体的安全疏散具有其特殊性,因此,需要对老年公寓进行特殊的消防安全设计,有针对性地保障火灾发生情况下老年人群体的安全。通过BLOB跟踪算法对老年人运动样本进行安全疏散运动参数计算,分析老年人在火灾疏散中的特点,预测老年人在火灾情况下安全疏散速度及所需时间,并根据计算结果指出老年公寓建筑消防安全设计重点。

Prediction of safety evacuation time in elderly population based on BLOB tracking algorithm Safe- ty evacuation design is an important part in the fireproof design on buildings, and the safety evacuation of the senior citizens is particular, therefore, it＇s necessary to make special design for the elderly, targeting to protect their safety under the circumstance of fire. This paper calculated the safe evacuation motion parame- ters in sports samples of the elderly through BLOB tracking algorithm,analyzed the characteristics of the elderly in fire evacuation, forecasted the velocity and time of the safety evacuation for the elderly under the fire condition, and pointed out the key in construction of senile apartments about firefighting designing based on the calculated results.
