A method and system for testing the stability of a child's stroller based on image recognition
By separating the geometric changes of the flexible and rigid regions of the stroller using image recognition technology, generating internal deformation and external displacement sequences, and combining this with two-dimensional phase space analysis, the subjectivity and error problems of traditional testing methods are solved, and a more accurate assessment of the tipping state is achieved.

Abstract
一种基于图像识别的儿童推车稳定性测试方法及系统，在该方法中，通过获取推车动态偏载测试的连续帧图像，分别提取表征座兜形变的柔性扰动区域和表征车架的刚性承载区域；据此分别计算柔性轮廓变化量与刚性空间位移量，生成内部形变特征序列和外部刚性偏移序列。通过监测内部形变序列的波动幅度，将幅度下降并维持稳定的起始时刻定为内部形变饱和点；随后提取该点后外部刚性偏移序列的时序变化率，当该变化率超过预设失稳阈值时，确认偏载能量由内部缓冲转化为整体倾覆，进而将该饱和点判定为推车的临界倾翻状态。本申请用于提高对推车真实临界倾翻状态评估的准确度。
