Method for promoting accuracy of preset position of dome camera

Abstract

The invention relates to a method for promoting the accuracy of a preset position of a dome camera, which comprises the following steps: when a user stores a preset position, a microprocessor MCU (Microprogrammed Control Unit) simultaneously stores a movement direction of the dome camera at the time into an EEPROM (Electrically Erasable Programmable Read-Only Memory); and when the user calls the preset position, the microprocessor MCU calls the preset movement direction of the dome camera from the EEPROM, compares the preset movement direction of the dome camera with a currently actual movement direction of the dome camera, does not carry out correction if the preset movement direction of the dome camera is the same with the currently actual movement direction of the dome camera, and carries out compensation and correction if the preset movement direction of the dome camera is opposite to the currently actual movement direction of the dome camera. The return difference generated when the dome camera moves inversely is eliminated and the accuracy of the preset position of the dome camera is improved, so that the dome camera works more accurately.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a method for improving the precision of a dome camera preset position. Background technique [0002] The dome camera is an intelligent camera front end, its full name is a high-speed intelligent dome camera, or an integrated high-speed dome smart dome, or a fast dome for short, or a high-speed dome for short. The high-speed dome is the most complex camera front end with the best comprehensive performance in the monitoring system, and can adapt to high-density and most complex monitoring occasions. The dome camera is a highly integrated product that integrates the pan-tilt system, communication system and camera system. The pan-tilt system refers to the rotating part driven by the motor, and the communication system refers to the control of the motor and the processing of images and signals. , The camera system refers to the all-in-one movement used. Between several major system...

AI Technical Summary

Problems solved by technology

The large rotational inertia of the load carried by the pan / tilt determines that the torque of the pan / tilt drive motor must be large. Due to product cost factors, the distance between the mechanical gears of the drive motor and the accuracy of the structural parts of the ordinary pan / tilt have a certain gap with the high-end smart pan / tilt. , resulting in an error in the precision of the preset position, and calling the preset position for a long time will cause the error to accumulate, causing the preset position to completely deviate from the original set position
