Vision-based trackless electric door operation control method, device and system

Abstract

The present invention relates to a vision-based trackless electric door operation control method, device and system, the method comprising: S1, acquiring the current image in the moving direction of the electric door collected by an image acquisition device; S2, using a preset method to extract the current image Current feature, comparing the current feature of the extracted current image with the pre-stored feature, judging whether the current feature matches the pre-stored feature, if so, perform step S4, if not, perform step S3; S3, output control signal to control the electric door to stop ; S4, analyzing and processing the current image, and combining the movement information of the head of the electric door to obtain the offset information of the head of the electric door; S5, controlling the operation of the electric door according to the offset information of the head. The present invention can effectively remove traditional magnetic nails or guide rails, avoid obstacles accurately without adding additional infrared sensors, realize navigation of electric doors more accurately, and effectively prevent electric doors from wandering.

Description

technical field [0001] The present invention relates to the field of door control, and more specifically relates to a vision-based trackless electric door operation control method, device and system. Background technique [0002] The gates of places such as factories or schools are generally opened or closed by one or more motors dragging the fence-like gates. At present, most electric doors on the market have guide rails or magnetic nails embedded in the ground, through which the direction of motion of the electric door can be controlled to prevent the electric door from drifting. [0003] However, there are certain defects in these two methods. For the guide rail method, because the guide rail protrudes from the ground, the vehicle will bump and shake when the vehicle passes by, and the frequent rolling of the vehicle will also cause damage to the guide rail. In addition, the guide rail protrudes from the ground. Affect the appearance. For the magnetic nail method, it is...

[0003] However, there are certain defects in these two methods. For the guide rail method, because the guide rail protrudes from the ground, the vehicle will bump and shake when the vehicle passes by, and the guide rail will be damaged due to the frequent rolling of the vehicle. In addition, the guide rail protrudes from the ground. Affect the appearance

For the magnetic nail method, it is necessary to drill holes in the ground during installation, which not only destroys the beauty and physical structure of the ground itself, but also increases the installation labor cost and material cost. The installation cost is high and the installation efficiency is low.
