step S23: each group of camera modules shoots an imaged picture and makes a comparison analysis with a brand new umbrella sample picture;
step S24: the breakage rate calculation unit calculates the breakage rate of the current umbrella compared with that of the new umbrella, and evaluates the current value of the umbrella by calculating the breakage rate;
step S25: comparing the current estimated generation value of the umbrella with the last estimated generation value of the umbrella which is called out in the umbrella value database module, when the estimated umbrella value is smaller than or equal to the last estimated value of the umbrella, judging the result as accurate by the accuracy judging unit, and when the estimated umbrella value is larger than the last estimated value of the umbrella, judging the result as inaccurate by the accuracy judging unit, restarting the photographing unit to perform re-photographing calculation evaluation.
4. A blockchain method of network hosting an application platform as in claim 3, wherein: the step S23 further includes:
the imaging contrast module is used for comparing imaging pictures shot by each group of camera modules with corresponding brand new umbrella sample pictures, wherein the two groups of camera modules are mainly responsible for shooting the whole umbrella cover and the whole umbrella support, the damage judging unit is used for automatically identifying whether the umbrella cover has light leakage emitted by the light capturing unit and whether the umbrella support has super-radian bending, when the umbrella cover has light leakage or the support super-radian bending, the umbrella is judged to be damaged, and an electric signal is transmitted to the damage rate calculating unit, so that the value of the umbrella is directly estimated to be 0; the rest camera modules are respectively a color calling camera module and a detail calling cameraThe head module is used for collecting the color of the umbrella, comparing the color with the color of a brand new umbrella sample to obtain a color standard difference value delta E, extracting different local characteristics of the umbrella in an amplified mode by the detail collecting camera module, and measuring the tie distance of the crease interval of the umbrella cover
5. The blockchain method of claim 4 wherein the network hosts the application platform, wherein: the step S24 further includes:
the damage rate calculating unit judges whether the umbrella is damaged or not through the integral sample of the current umbrella and the totally new umbrella, outputs 0 when the umbrella is damaged, and compares chromatic aberration, so that the current degree of freshness of the umbrella is judged according to the fading condition of the umbrella, namely the damage rate, meanwhile, the crease density of the umbrella is considered, the evaluation accuracy of the value of the umbrella is further improved, and the calculation formula of the damage rate value of the damage rate calculating unit is as follows:
the actual value of the umbrella is as follows:
T at present ＝(1-P)×T Original source
Wherein P is the refractive index value calculated by the refractive index calculating unit, delta E is the color contrast value obtained by comparing the currently detected umbrella with the new umbrella sample,to measure the tie distance value of the umbrella cover crease interval, beta is a constant value larger than 0, T At present To obtain the existing value of the umbrella through the evaluation of the value evaluation end, T Original source The novel umbrella has selling value.
6. The blockchain method of claim 5, wherein the network hosts the application platform, wherein: in the step S4, the cost of the escrow is:
wherein D is the hosting time, the unit is that the day is less than one day and calculated according to one day, the first day deduction is more, the original value is higher, the basic service fee is higher, the subsequent deduction amount is the preservation cost and the natural aging loss of the umbrella, when the hosting time is within 5 days, the preservation cost is continuously reduced, and the umbrella with higher value is higher in quality and is not easy to age and damage, so the preservation cost and the natural aging loss are less, the subsequent deduction cost is more in change reduction amount, and the hosting cost is unchanged after more than 5 days, and T is not changed Towing vehicle For the cost generated by the trusteeship, the value of the umbrella taken out by the user next time is the value estimated by the value estimating terminal minus the cost value generated by the trusteeship; besides selecting the hosting, the umbrella can be used always by being kept at the user, and can be recycled and sold, and the value of the umbrella when sold is T Sell (E) ＝0.8·T At present Thereby realizing recycling.
7. The blockchain method of claim 6, wherein the network hosts the application platform: in the step S1, when any sharing management end buys an umbrella, a brand new umbrella and a second-hand umbrella can be selected to be bought, and the price of the second-hand umbrella is the value T of the selected umbrella after being evaluated at the value evaluation end At present 。
