Abstract
The invention discloses an intelligent cat eye system for automatically starting doorbell call. A laser transmitter is arranged at a height h right below a camera, a distance measurement module and a distance analysis module are arranged in an external processor, the distance measurement module is used for calculating a distance D between a target and the laser transmitter according to a focusing angle of a laser point and the height h, and D is equal to h/tan ; the distance analysis module is used for comparing the distance D measured by the distance measurement module with a first preset distance threshold, and starting a doorbell call system when the distance D is smaller than or equal to the first preset distance threshold, the external processor sends a doorbell call signal to an internal processor, and the internal processor outputs a trigger signal to activate a call loudspeaker. According to the intelligent cat eye system disclosed by the invention, the camera calculates the distance between the target and the laser transmitter according to the focusing angle of the laser point and the height difference of the camera and the laser transmitter, judges whether a visitor is approaching to a room door according to the distance, and automatically starts the doorbell call system when the visitor approaches to the room door, therefore is application is intelligent and convenient.
Description
Technical field
The present invention relates to a kind of electronic peephole viewer, particularly relate to a kind of intelligent peephole system of automatic startup doorbell calling.
Background technology
Tradition opal adopts optical imaging modalities, has a lot of inconvenience in actual use.Such as, visual angle is large not, and viewing is limited in scope.Men Caineng must be pressed close to and see situation outdoors.Evening, corridor just can not use without lamp.Old man's eyesight is bad, and child's height is inadequate, is not easy to them and uses.Except inconvenience, the more important thing is to there is potential safety hazard: occurred that opal peeps device on the market, by it, offender can clearly from seeing indoor situation outdoors, except privacy has no way of except protection, more to implement crime to offender and providing convenient.We often can see relevant report from media: offender finds no one in room, pulls down opal, put in door open lockset and carry out the case such as stealing with instrument.
Electronic peephole viewer, also known as video doorbell, it is integrated with the function of opal and doorbell, and overcome deficiency and the potential safety hazard of traditional optical opal, add the function of monitoring aspect simultaneously, being widely used in family and high-grade hotel doorway at present, is one upgrading and the substitute products of traditional optical cat-eye.But blemish in an otherwise perfect thing, existing electronic peephole viewer degree of intelligence is not high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of intelligent peephole system of automatic startup doorbell calling is provided, is detected by camera and generating laser realize target distance, and automatically start doorbell calling by target range.
The object of the invention is to be achieved through the following technical solutions: the intelligent peephole system automatically starting doorbell calling, comprise outer machine and interior machine, outer machine comprises camera, generating laser and outer machine processor, generating laser and camera are connected with outer machine processor respectively, interior machine comprises calling loudspeaker and interior machine processor, calling loudspeaker are connected with interior machine processor, are connected between outer machine processor with interior machine processor by cordless communication network;
Generating laser is arranged at height h place immediately below camera, range finder module and distance analysis module is provided with in described outer machine processor, range finder module is used for according to laser point focusing angle and the distance D between height h calculating target and generating laser, D=h/tan;
Distance analysis module is used for the distance D that recorded by range finder module and the first predeterminable range threshold value is compared, when distance D is less than or equal to the first predeterminable range threshold value, start doorbell calling system, the inside machine processor of outer machine processor sends doorbell call signal, and interior machine processor exports activation trigger signal calling loudspeaker.
It is radium-shine that the emission state of described generating laser is that intermittence sends, and radium-shine launch time is less than 0.1s, and interval time is greater than 0.1s, and a transmitting cycle is 0.2s.
The radium-shine light-emitting window eyeglass of described generating laser is provided with scale.
The invention has the beneficial effects as follows:
1) camera calculates distance between target and generating laser according to laser point focusing angle and the difference in height of camera and generating laser, and according to this Distance Judgment visitor whether close to door, when visitor is near door, automatic opening door bell calling system, uses intelligence, convenience.
2) be less than 0.1S radium-shine launch time, interval time is greater than 0.1S, one-period about 0.2S, and this radiation pattern can guarantee that human eye is insensitive to radium-shine launch time, prevents radium-shine burning from penetrating eyes.
3) the radium-shine light-emitting window eyeglass of generating laser adds scale, and this design, while guaranteeing focusing, can calculate moving target distance fast.
Accompanying drawing explanation
Fig. 1 is range measurement principle figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
The intelligent peephole system of automatic startup doorbell calling, comprise outer machine and interior machine, outer machine comprises camera, generating laser and outer machine processor, generating laser and camera are connected with outer machine processor respectively, interior machine comprises calling loudspeaker and interior machine processor, calling loudspeaker are connected with interior machine processor, are connected between outer machine processor with interior machine processor by cordless communication network.
As shown in Figure 1, generating laser is arranged at height h place immediately below camera, be provided with range finder module and distance analysis module in described outer machine processor, range finder module is used for according to laser point focusing angle and the distance D between height h calculating target and generating laser, D=h/tan;
Distance analysis module is used for the distance D that recorded by range finder module and the first predeterminable range threshold value (can be set to 50CM) is compared, when distance D is less than or equal to the first predeterminable range threshold value, start doorbell calling system, the inside machine processor of outer machine processor sends doorbell call signal, and interior machine processor exports activation trigger signal calling loudspeaker.Automatic opening door bell calling system, and by the instantaneous transmission of camera collection information in indoor wireless device buffer storage and acquiescence display device.Indoor owner can select else nearby and get respective electronic equipment and check image, carries out visiting checking work.When owner not time, outdoor images is gathered image information buffer memory and is sent to by the network equipment on the mobile device of owner's setting by camera, reminds in family and has people to come to visit, and provides corresponding video interception information to check for owner.
