Store transport module with data, be connected with monitoring camera by CAN communication circuit or physical hardwired, car
Door control module is connected with car door by physical hardwired, for receiving the output signal that image processing module sends,
And by electric-controlled hydraulic mode, open or close car door.
The present invention is further improved by, and data storage transport module is vehicle-mounted single-chip microcomputer.
The present invention is further improved by, and image processing module, for the space field transformation to image, utilizes
Fourier algorithm is converted to transform-domain processing to image in the process of spatial domain, after pre-processing, carries out figure
As segmentation, characteristic significant in image is extracted, then the image obtained in car is known
Not, finally judge whether have in passenger image region.
The present invention is further improved by, and uses edge extracting or region segmentation method will to have a mind in image
The characteristic of justice extracts, and wherein, in image, significant characteristic includes the edge of image.
The present invention is further improved by, and this intelligent monitor system is arranged on the ECU circuit of commercial car
Place.
The present invention is further improved by, and door control module uses logical trigger to combine electric-controlled hydraulic side
Formula, opens or closes car door.
Relative to prior art, the present invention has a following beneficial effect:
The intelligent monitor system that the present invention provides can well monitor the activity situation of child in school bus, prevents
Child is because a variety of causes is omitted in car.Utilize existing vehicle-mounted camera and car-mounted computer, so that it may
To realize this purpose, it is not necessary to extra design or change automobile on a large scale, reduce cost.At vapour
The passive security field of car has more preferable development prospect.
Accompanying drawing illustrates:
Fig. 1 is monitoring method flow diagram based on the present invention a kind of commercial car intelligent monitor system.
Detailed description of the invention:
Below in conjunction with drawings and Examples, the present invention is further described in detail.
As it is shown in figure 1, one commercial car intelligent monitor system of the present invention, it is characterised in that include that image is adopted
Collection module, image processing module, data storage transport module and door control module；Wherein, image acquisition
Module is positioned over the surface of front windshield or rear seat windscreen, utilizes monitoring camera gather image and pass
Being defeated by image processing module, image processing module stores transport module with data, by CAN communication circuit or
Person's physical hardwired is connected with monitoring camera, and door control module is connected with car door by physical hardwired, is used for
Receive the output signal that image processing module sends, and by electric-controlled hydraulic mode, open or close car door.
Wherein, the image processing module space field transformation to image, utilize Fourier algorithm to image in space
The process in territory is converted to transform-domain processing, and such being advantageous in that greatly reduces amount of calculation, namely hardware money
The computational load in source, and digital filtering can be convenient for and process.After pre-processing, carry out image to divide
Cut, characteristic significant in image is extracted, the edge etc. of such as image, the side mainly taked
Method is the edge extracting of current main flow, region segmentation method, is identified by the image obtained, finally in car
Judge whether have in passenger image region.
Specifically, the present invention utilize (after consideration, it is only necessary to this external hardware of monitoring camera),
Monitoring camera and vehicle-mounted single-chip microcomputer, by Computer Image Processing function, camera monitoring system, automobile
Car door, and triple combination is got up, use monitoring camera to transmit the situation in school bus car in real time, and will adopt
Collect to picture signal be delivered in car-mounted computer.Computer Image Processing function treatment analysis is utilized to image
The view data that head photographs, first carries out spatial domain process, Morphological scale-space to the signal gathered；Secondly
Signal is carried out modal idenlification, thus excavates deeper information in image, it is achieved in school bus car
Monitoring.Use computer intelligence image identification function, develop image procossing, pattern recognition and image reason
Solve, can qualitative, the personnel amount determined in quantitative analysis car and kind, and the result after be able to analyzing
