The present invention provides a convenient marking method, system, equipment and storage medium for an object to be identified, including the following steps: Step S1: Collect several images, the images include at least one commodity area; Step S2: Preset a mark frame, so that the image can move relative to the marked frame, so as to drag a commodity area on each of the images into the marked frame; Labeling is performed such that each product area has a product label box. The present invention can drag the commodity area on the image to a preset mark frame to mark the commodity region by dragging the image, realizes the possibility of marking the image collected by the mobile terminal, such as a mobile phone, and improves the picture collection and The efficiency of marking can outsource the complicated work of image marking through the mobile APP, and realize the possibility of collecting and marking a large number of pictures.

The invention relates to a video trigger method and a device. The video trigger method comprises the following steps: a trigger signal is output when vehicle characteristics are detected in a virtual coil of a video image, and the vehicle characteristics comprise the characteristics of vehicle bottom shadow. When the characteristics of vehicle bottom shadow are detected in the virtual coil of a video image, the output of the trigger signal comprises the following steps: pixel points in the virtual coil, which have a gray value smaller than or equal to a threshold of vehicle bottom shadow, arejudged as characteristic points of vehicle bottom shadow; the trigger signal is output when the sum of the characteristic points of vehicle bottom shadow is larger than a first preset sum threshold. The invention can obtain a high trigger rate and a low error trigger rate.

The invention discloses a contract trigger method and device based on a block chain. The method comprises steps that the transaction information of a transaction presently processed by a block and relevant to a contract is acquired, wherein the contract comprises the identifier information of the transaction, and the transaction information comprises the transaction number and the total amount information; according to the number and the total amount information, whether the presently-accomplished transaction is the last one is determined; if yes, the contract is triggered. The method is advantaged in that the contract itself can be spontaneously triggered.
