S103、从预设的M个净味策略中选取与所述当前新鲜状态对应的目标净味策略，其中，M为不小于2的整数；
S104、通过所述目标净味策略对所述目标对象进行净味处理。
依据本公开内容的一些实施例，在步骤S101中，可以通过设置在冰箱中的摄像装置，每隔设定时间采集目标对象的图像，进而得到图像序列集。
依据本公开内容的一些实施例，目标对象可以蔬菜和水果等，例如可以是韭菜、芹菜、香蕉和苹果等；进一步的，摄像装置通常是摄像头，其数量可以为1个或多个，可以设置在冰箱内部的前后左右等方位上，本说明不作具体限制。
依据本公开内容的一些实施例，设定时间可以是固定时长，还可以变动时长，在是固定时长时，设定时长例如可以是2小时(h)，3h和6h等；在是变动时长时，在前一次采集图像是间隔n小时，后一次是间隔(n+1)小时进行图像采集，其中，n可以为不小于0的值，例如前一次是间隔1小时，再间隔2小时采集后一次的图像。
依据本公开内容的一些实施例，在通过多个摄像头每隔设定时间采集目标对象的图像时，可以将多个摄像头每次采集的图像作为一组图像，根据每次采集的一组图像按照时序进行排列，得到图像序列集；也可以将多个摄像头每次采集的图像拼接成一幅图像，再根据每次拼接的一幅图像按照时序进行排列，得到图像序列集。
在实际应用过程中，在通过多个摄像头每隔设定时间采集目标对象的图像时，可以将多个摄像头设置在冰箱内部的不同面上，如此，使得采集的目标对象的图像的 完整度更高，使得在后续判断时，其判断的准确性也会随之提高。
在得到图像序列集之后，执行步骤S102。
在步骤S102中，可以首先提取图像序列集中的初始图像和最后一次图像；将最后一次图像和初始图像进行比对，获取比对结果；根据比对结果，确定当前新鲜状态。
依据本公开内容的一些实施例，由于图像序列集中的图像是按时序排序的，由此可以根据图像序列集中的图像排序，从图像序列集中的初始图像和最后一次图像，然后将初始图像与最后一次图像进行比对，将最后一次图像和初始图像进行比对，获取目标对象的变化参数，并将变化参数作为比对结果，其中，变化参数包括色泽变化参数、软化变化参数和表面萎缩变化参数等参数中的至少一种参数；再获取到比对结果之后，确定出当前新鲜状态。
依据本公开内容的一些实施例，变化参数可以仅包括色泽变化参数，或，软化变化参数，或表面萎缩变化参数；变化参数还可以由色泽变化参数和软化变化参数组成，或者，由色泽变化参数和表面萎缩变化参数组成，或者，由软化变化参数和表面萎缩变化参数组成。优选地，变化参数可以包括色泽变化参数、软化变化参数和表面萎缩变化参数。下面具体以变化参数包括色泽变化参数、软化变化参数和表面萎缩变化参数为例。
依据本公开内容的一些实施例，在获取到比对结果之后，可以从预设的N种设定状态中获取与比对结果对应的设定状态，并将与比对结果对应的设定状态作为当前新鲜状态。其中，N种设定状态可以包括新鲜状态、次新鲜状态和腐败状态等状态中的至少两种。下面具体以N种设定状态包括新鲜状态、次新鲜状态和腐败状态为例，多种设定参数具体如下表1所示：
Figure PCTCN2021108613-appb-000001
Figure PCTCN2021108613-appb-000002
表1
例如，以目标对象以韭菜为例，每隔2小时采集一次韭菜的图像，采集的图像序列集依次为图像A1、A2、A3和A4，从图像序列集中提取到初始图像为A1，最后一次图像为A4，将A1和A4进行比对，获取韭菜的色泽变化参数、软化变化参数和表面萎缩变化参数，若色泽变化参数表征从翠绿色变成了黄绿色，且软化变化参数表征从坚挺变成了叶子软化，以及表面萎缩变化参数表征从表面完整变成了表面有褶皱，则再根据韭菜的色泽变化参数、软化变化参数和表面萎缩变化参数，从表1中确定韭菜的当前新鲜状态为次新鲜状态。
在实际应用过程中，若目标对象为食物，而食物在正常状态下整体轮廓比较饱满；以及在放置时间较长之后，其水分流失较多，整体轮廓会有一定程度的萎缩；以及食物在正常状态下表面不会存在斑点；以及在放置时间较长之后，可能会出现腐烂变质现象，表面会出现一些黑色的斑点；如此，可以通过图像比对，获取食物的软化变化参数和表面萎缩变化参数，还参考水果的色泽变化参数，进而能够更准确的判断食物的当前新鲜状态。
以及，若目标对象为水果，而水果在正常状态下表面比较光滑；若放置时间较长，水分流失较多，其表面可能会出现褶皱，而且水果在正常状态下颜色较鲜艳；若放置时间较长，可能会出现腐烂变质现象，颜色会变深甚至变黑；如此，可以通过图像比对，获取水果的表面萎缩变化参数和色泽变化参数，还参考水果的色泽变化参数，进而能够更准确的判断食物的当前新鲜状态。
以及，若目标对象为蔬菜，而蔬菜在正常状态下整体轮廓比较饱满；以及在放置时间较长之后，其水分流失较多，整体轮廓会有一定程度的萎缩；以及蔬菜在正常状态下通常为翠绿色且颜色较正；以及在放置时间较长之后，颜色会变黄变黑等；如此，可以通过图像比对，获取蔬菜的软化变化参数和色泽变化参数，还可以参考蔬菜的表面萎缩变化参数，进而能够更准确的判断蔬菜的当前新鲜状态。
在确定当前新鲜状态之后，执行步骤S103。
在步骤S103之前，会预先设定M个净味策略，在预先设定M个净味策略之后，会将M个净味策略与N种设定状态对应，在M＝N时，M个净味策略与N种设定状态一一对应，在M<N时，至少存在一个净味策略对应的两种设定状态，且每种设定状态至少对应一个净味策略；如此，使得在从N个设定状态中确定了当前新鲜状态之后，可以根据N个设定状态与M个净味策略的对应关系，从M个净味策略中选取与当前新鲜状态对应的净味策略，并将选取的净味策略作为目标净味策略。
依据本公开内容的一些实施例，在预先设定M个净味策略和N种设定状态之后，还可以将N种设定状态进行分级，得到N个新鲜等级，使得M个净味策略与N种新鲜等级对应，新鲜等级可以用数字进行表示例如第一级用001表示和第二级用010表示，以使得在获取到新鲜等级之后，通过新鲜等级对应的数字从M个净味策略中查找到与新鲜等级对应的净味策略，以提高查找的效率。
依据本公开内容的一些实施例，在设定M个净味策略之后，还可以根据当前新鲜状态所对应的新鲜等级，从M个净味策略中选取与新鲜等级对应的净味策略，并将选取的净味策略作为目标净味策略。此时，M个净味策略与新鲜等级对应，且N中设定状态中每种设定状态对应一个新鲜等级，若N种设定状态可以包括新鲜状态、次新鲜状态和腐败状态，此时，新鲜状态、次新鲜状态和腐败状态依次对应第一级、第二级和第三级，第一级的新鲜度最高，第二级次之，第三级的新鲜度最低，此时，M个净味策略可以3个净味策略，依次为低频净味策略，高频净味策略和高压高频净味策略，其中，低频净味策略与第一级对应，高频净味策略与第二级对应，高压高频净味策略与第三级对应。
此时，以目标对象以韭菜为例，并从表1中确定韭菜的当前新鲜状态为次新鲜状态，可以确定当前新鲜状态所对应的新鲜等级为第二级，由于M个净味策略中与第二级对应的净味策略为高频净味策略，则确定目标净味策略为高频净味策略。
在确定目标净味策略之后，执行步骤S104。
在步骤S104中，执行目标净味策略，以通过目标净味策略对目标对象进行净味处理，以降低冰箱中出现异味的概率。
依据本公开内容的一些实施例，可以在通过冰箱中设置的净化杀菌模块来执行目标净味策略，其中，净味杀菌模块可以包括高压发生器、离子场净化器和循环风机，其净味原理是利用高压电激发放电单元产生大量活性的高能自由基，同时配合贵金属陶瓷催化剂的协同催化作用，使用循环风机制造气流使得冰箱内空气得以循环通过离子场净化器，从而起到快速除味、除菌的目的。高压发生器含有可调输出电压模块，在一定电压范围内，电压值越高，净化效果越好。
依据本公开内容的一些实施例，若M个净味策略包含低频净味策略，高频净味策略和高压高频净味策略，其中，低频净味策略的具体步骤为：控制冰箱的净化杀菌模块的电压值为第一电压，开停比例为第一比例，以及输出频率为第一频率；高频净味策略的具体步骤为：控制冰箱的净化杀菌模块的电压值为第二电压，开停比例为第二比例，以及输出频率为第二频率，其中，第二电压不小于第一电压，第二比例大于第一比例，第二频率大于第一频率；以及，高压高频净味策略的具体步骤为：控制冰箱的净化杀菌模块的电压值为第三电压，开停比例为第三比例，以及输出频率为第三频率，其中，第三电压大于第二电压，第二比例不小于第一比例，第三频率不小于第二频率。如此，使得在新鲜等级为第一级时，执行低频净味策略；在新鲜等级为第二级时，执行高频净味策略；以及在新鲜等级为第三级时，执行高频高压净味策略。
若净味杀菌模块包括高压发生器、离子场净化器和循环风机，此时，低频净味策略的具体步骤为控制高压发生器的电压为第一电压，控制离子净化器的开停比例为第一比例，控制循环风机的输出频率为第一频率，相应地，高频净味策略和高压高频净味策略的具体步骤可以参考低频净味策略的具体步骤。例如，低频净味策略中的第一电压可以为2000v，第一比例为1:8和第一频率为40Hz；高频净味策略中的第二电压可以为2000v，第二比例为1:5和第二频率为55Hz；以及，高压高频净味策略中的第三电压可以为2000v，第三比例为1:5和第三频率为75Hz等。
依据本公开内容的一些实施例，N为大于3的值时，每种设定状态对应一个级别，使得N种设定状态对应N个级别，根据级别的不同，确定不同的净味策略。如此，根据当前新鲜状态所对应的新鲜级别，确定目标净味策略，使得目标净味策略与目标对象的新鲜级别的匹配度较高，由于新鲜级别的新鲜程度从高到低排序是从第 一级，第二级依次到第N级，在新鲜级别表征新鲜程度越低时，其对应的净味策略去除净味的功率越大，在单位时间内能够去除掉更多的气味，从而能够有效提高净味的精度。
基于上述技术方案，每隔设定时间采集设置在所述冰箱中目标对象的图像，得到图像序列集；将所述图像序列集的图像进行图像比对，确定所述目标对象的当前新鲜状态；从预设的M个净味策略中选取与所述当前新鲜状态对应的目标净味策略；通过所述目标净味策略对所述目标对象进行净味处理；由此可知，目标图像的当前新鲜状态是根据图像序列集中的图像进行图像比对而确定的，而目标净味策略是根据新鲜等级从M个净味策略中确定的，如此，可以根据新鲜等级的不同采取不同的净味策略，使得目标净味策略与目标对象的当前新鲜状态匹配度更高，使得净味处理的精确度更高。
