Synchronous operation of light emitting diodes for vision systems

A vision system includes an image sensor configured to be exposed to a scene during exposure times, a light emitting diode (LED) driver operatively connected to the image sensor, an LED associated with the image sensor and operatively connected to the LED driver, and one or more processing circuits that synchronize pulses of an enable signal to the exposure times of the image sensor so that each pulse of the enable signal overlaps with one of the exposure times. The pulses of the enable signal are used by the LED driver to cause the LED to output light to the scene.

Live streaming auditing method and apparatus, server, and storage medium

The present application provides a live streaming auditing method and apparatus, a server, and a storage medium. The live streaming auditing method comprises: performing, by means of a high-accuracy auditing model and a high-recall auditing model which are cascaded, preliminary violation auditing on the current live streaming frame in a to-be-audited live streaming room; and if the current live streaming frame passes the preliminary violation auditing, inputting, into a pre-constructed behavior auditing model, a first violation score of the current live streaming frame under the high-accuracy auditing model, a second violation score of the current live streaming frame under the high-recall auditing model, and a multi-dimensional behavior feature of the current live streaming frame in said live streaming room, to obtain a target violation score of the current live streaming frame.

Methods for predicting a stability of a steel cylinder against tilt

Method for predicting a stability of a steel cylinder including: in response to the steel cylinder tilting toward a seaward side at an arbitrary rotation point, obtaining a safety factor for the steel cylinder tilting toward the seaward side by determining an anti-tilt moment and a tilt moment when the steel cylinder is tilted to the seaward side; under a same rotation point, in response to determining that the steel cylinder is rotated toward a land side, determining the safety factor for the steel cylinder tilting toward the land side; taking a smaller safety factor as the safety factor under the rotation point; re-selecting a new rotation point, determining a safety factor corresponding to the new rotation point, and taking a safety factor with a smallest value among all rotation points as a final safety factor; and generating, based on the final safety factor, an anti-tilt instruction.
