This invention proposes a method for assembling a lightweight derrick, comprising the following steps: preparing an assembly site and configuring embedded ground bells; disassembling the derrick body into four components: upper, upper right, lower left, and lower right, respectively labeled a, b, c, and d; horizontally assembling components c and d, pre-tightening structural bolts; vertically assembling components b, c, and d together; horizontally assembling component a, installing outfitting parts, and erecting the assembly; hoisting component a onto components b, c, and d; and installing and laying pipelines, cables, and equipment between the components to complete the derrick assembly. This invention provides clear visibility of the straightness, verticality, and overall dimensions of the main structure in a horizontal configuration, allowing for more precise and clear control; it grounds high-altitude operations, greatly reducing construction difficulty and improving efficiency; it is applicable to the assembly of all lightweight derricks, has wide applicability, and improves the safety and efficiency of the entire construction process.

The application discloses a kind of based on computer vision's intelligent playing card dispensing device and method.The device includes computer vision identification module, mechanical card turning mechanism, automatic shuffling mechanism, intelligent dispensing mechanism and man-machine interaction module.The computer vision identification module is automatically judged playing card front and back by camera and image processing algorithm;The mechanical card turning mechanism is turned into back up with face up playing card;The automatic shuffling mechanism adopts cut card type shuffling, supports fixed or random shuffling times;The intelligent dispensing mechanism is equipped with rotatable card outlet, and can be sequentially distributed to 2-6 players from the specified player in clockwise / anticlockwise direction;The device supports three sets of 162 playing cards at most.The application solves the problems of uncontrollable card face direction, insufficient shuffling randomness and inaccurate dispensing rule execution in manual dispensing, and realizes the full-process automation of playing card processing.
