Embodiment Construction

[0028] figure 1 It is a system structure diagram of the doorbell of the present invention. Such as figure 1 As shown, the system includes an image acquisition module, an image analysis module, a judgment drive module and a reminder module.

[0029] The image acquisition module acquires images in the corridor, wherein the image acquisition module can use any device capable of acquiring images. Considering the cost, it is preferable to use a camera. In one example, the image acquisition module uses a low-resolution CMOS camera. Alternatively, the lens of the camera can also be made of other cheap transparent materials such as plastic to reduce costs.

[0030] After the image acquisition module acquires the image, it is transmitted to the image analysis module.

[0031] The image analysis and processing module adopts the face detection and tracking method to obtain the face information in the image, and sends it to the judgment drive module. The judging drive module determi...

Abstract

The invention relates to an automatic doorbell device and a method how to realize the automatic doorbell device. The automatic doorbell device comprises an image acquisition module used for image acquisition, an image analysis module used for analyzing images for facial information by an image analysis algorithm, a drive judgment module used for judging whether to generate a driving signal according to the facial information, and a reminding module used for sending information when driven by the driving signal. The invention has the advantages that the invention can greatly reduce false alarmrate of doorbells, and the invention can also be used as an effective alarm device.

Description

technical field [0001] The invention relates to a doorbell, in particular to an automatic doorbell which automatically senses changes in the external environment and automatically generates reminders and a realization method thereof. Background technique [0002] Doorbell is an essential item in home life. However, common doorbells require visitors to manually press a button to drive the sounding module to make a sound to remind the owner that there is a visitor, which is not convenient enough. As a result, many automatic doorbells came into being. [0003] A Chinese patent (publication number CN1053316) discloses a method for automatically driving a doorbell. The method uses a photoresistor to automatically measure the sudden change in ambient brightness, and uses a sudden change signal to drive the doorbell. However, the biggest defect of this method is that it is easy to generate false alarms due to interference. For example, when someone passes by the corridor or the a...
