This invention relates to the field of measurement data analysis technology, specifically to an engineering measurement data analysis method and system based on image recognition. The method includes the following steps: using an industrial camera to identify structural edges, measurement markers, and calibration rulers to form a reference set of measurement point coordinates; establishing corresponding quantities of directional scales based on the calibration ruler direction; combining the displacement relationship of the measurement points to form a measurement point interval characterization set; determining the edge deviation reference rate; and finally forming a boundary positioning association result. This invention uses grayscale abrupt changes to define edges and construct measurement point positioning references; calculates the lateral and longitudinal displacements of the calibration ruler to extract corresponding directional scales; combines measurement point displacement and edge direction to form interval characterizations; analyzes the normal span and surface deviation state to form edge references; and combines the boundary extension orientation to define the associated segments of the arrangement trajectory. This reduces interference from manual interpretation, maintains consistency of multi-directional conversion benchmarks, controls the error accumulation process, and improves the coherence and stability of engineering monitoring data processing.

This invention relates to a fast selection interaction method, apparatus, and electronic device for an electronic paper display, comprising: rendering and displaying an interactive interface containing multiple candidate options on an electronic paper display unit, wherein the interactive interface does not display a movable visual focus used to indicate the current candidate option; establishing a corresponding mapping relationship between each option in the multiple candidate options and each specific physical direction button, the mapping relationship being determined based on the spatial arrangement of each option in the interactive interface; responding to a detected trigger operation on a target physical direction button in a group of physical direction buttons, identifying the trigger operation as a selection operation on the option mapped to the target physical direction button according to the mapping relationship, and executing the subsequent logic corresponding to that option; during the process of the trigger operation being responded to and the subsequent logic being executed, interface refresh triggered by moving the movable visual focus is not performed. This invention can avoid frequent screen refreshes and operation delays caused by cursor movement.

This invention relates to the field of mortar testing, specifically to a mortar consistency testing device for environmentally friendly mortar. It includes a lead screw slide with its output end fixed to a worktable. A cover is located beside the worktable, and a cone-shaped device coaxially and detachably holds the mortar. A vibration mechanism is located at the lower end of the cover. An infrared sensor is fixedly connected to the lead screw slide near the cover, and the infrared sensor is electrically connected to a controller. An electromagnet is fixedly connected to the lead screw slide below the sensor. A support is fixedly connected to the lead screw slide below the electromagnet, and an electric actuator is fixedly connected to the upper end of the support. A retaining ring is fixedly connected to the end of the support away from the lead screw slide, and a guide rod is coaxially connected to the retaining ring. A permanent magnet is fixedly connected to the upper end of the guide rod near the lead screw slide, and a cone-shaped device coaxially with the cone-shaped device is fixed to the lower end of the guide rod. During testing, the cone is filled with mortar and fixed coaxially with the cover cylinder. The vibration mechanism disperses the mortar. The screw slide and electric actuator adjust the position of the cone, and the electromagnet attracts the guide rod. After the power is cut off, the cone falls, the infrared sensor detects the displacement and transmits it to the controller to calculate the consistency, thus achieving accurate testing.

This invention belongs to the field of multi-live-room synchronous live streaming technology, specifically involving a method for multi-live-room synchronous live streaming based on AI digital humans. The method includes: deploying a system template; constructing audience profiles and script templates; rendering seeds and initializing a lightweight ledger; performing edge deterministic rendering during live streaming; employing distributed ledger recording and local perception optimization; performing playback verification based on the ledger and frame records; quantifying business effects and conducting offline training. This invention can reduce the cross-node consistency of visual and audio-visual aspects of digital humans in multiple live-streaming rooms, thereby reducing the perceptual latency on the viewing end and improving the real-time viewing experience for the audience.
