功能：1:1比对性能测试程序
|
||
1. 基于标准特征集所对应的原始图像样本，生成标准特征集并保存。
|
||
func: generate_event_and_stdfeatures():
|
||
(1) get_std_barcodeDict(stdSamplePath, stdBarcodePath)
|
||
提取 stdSamplePath 中样本地址，生成字典{barcode: [imgpath1, imgpath1, ...]}
|
||
并存储为 pickle 文件，barcode.pickle'''
|
||
(2) stdfeat_infer(stdBarcodePath, stdFeaturePath, bcdSet=None)
|
||
标准特征提取，并保存至文件夹 stdFeaturePath 中，
|
||
也可在运行过程中根据与购物事件集合 barcodes 交集执行
|
||
2. 1:1 比对性能测试，
|
||
func: contrast_performance_evaluate(resultPath)
|
||
(1) 求购物事件和标准特征级 Barcode 交集，构造 evtDict、stdDict
|
||
(2) 构造扫 A 放 A、扫 A 放 B 组合，mergePairs = AA_list + AB_list
|
||
(3) 循环计算 mergePairs 中元素 "(A, A) 或 (A, B)" 相似度;
|
||
对于未保存的轨迹图像或标准 barcode 图像，保存图像
|
||
(4) 保存计算结果
|
||
|
||
|
||
3. precise、recall等指标计算
|
||
