Description
Technical Field
The invention relates to public transportation safety technology, in particular to a method for installing a vision blind area camera device.
Background
In the prior art, although the rearview mirrors for buses and commercial buses can provide the conditions of vehicles on two sides of a bus driver in the running process of the buses and commercial buses, the driver can not observe the environment of a region, which is in a certain direction of the automobile and is close to the automobile, due to the running speed, the height of the vehicle body, the angle of the rearview mirrors, the turning of the vehicle and the visual field of human vision during the driving of the driver; at present, many pedestrians or other passersby do not know the visual blind areas of driving, and usually consider that an automobile driver should see himself so as to break into the visual blind areas of the vehicle, and at this time, if the driver does not pay attention to the traffic conditions of the visual blind areas on two sides of the driver, traffic accidents easily occur; in order to prevent such situations, the camera device is usually installed at the body of the bus or the commercial bus and is connected with the display screen in the bus or the commercial bus, so that the situation that the image viewing angle is required to be corresponding to a designated area in the driving process of the bus or the commercial bus is avoided, the viewing angle calibration of the common camera device is troublesome, the viewing angle of each bus or commercial bus is required to be calibrated and debugged one by one, time and labor are wasted, and the consistency is difficult to ensure.

d. according to the picture in the external display screen, the lens visual angle of the camera device is further adjusted;
e. disconnecting the camera device from an external display screen, and simultaneously connecting the lens view angle of the camera device after the adjustment with the display screen in the middle-large-sized vehicle to finish primary installation;
f. recording preliminary adjustment data and further adjustment data of the lens visual angle in the primary installation process;
g. installing the image pickup device on the body of the medium-sized and large-sized vehicle according to the adjustment data recorded in the step f, and finishing secondary installation;
h. according to the secondary installation step, the image pick-up devices are fixedly arranged on the rest of the large and medium-sized vehicle bodies in sequence. According to the method, the lens visual angle of the camera device arranged in the installation shell in an embedded mode is adjusted, and meanwhile, the camera devices of the following vehicles are installed in a unified mode according to recorded adjustment data, so that the time required for installing the camera devices in batches is shortened.
The distance between the outer edge of the mounting shell and the lens in the camera device in the step a is higher than the specification of the rubber sealing rubber strip for the doors and windows of the vehicle in the national standard HG/T3088-1999. This method prevents the rubber strip of the vehicle from covering the shooting angle of the camera device by requiring a spacing between the mounting housing and the lens in the camera device.
In a further aspect, the preliminary adjustment of the lens angle of view of the image capturing apparatus in the step b specifically includes: the scale dial plate arranged in the outer surface of the mounting shell and the reference mark line arranged on the camera device are pre-calibrated in advance, so that the lens visual angle of the camera device is initially locked in a vision blind area at the rear side of the middle-large vehicle when the middle-large vehicle turns. The method locks the lens visual angle of the image pickup device in a smaller section in advance by installing the scale dial in the shell and the reference mark in the image pickup device, thereby reducing the time for adjusting the lens visual angle of the image pickup device.
In a further aspect, in the step c, the photographing of the image by the initially adjusted image capturing device specifically includes: and the camera device is used for photographing pictures after the initial locking of the lens visual angle. According to the method, the picture shot after the initial adjustment of the visual angle of the camera device is displayed through the external display screen, so that the time of running back and forth from the inside of the vehicle to the outside of the vehicle for calibrating the visual angle of the lens is avoided.
In a further aspect, in the step d, the further adjustment of the lens angle of the image capturing apparatus specifically includes: after the picture shot after the initial locking of the view angle of the lens of the image pickup device is combined with the actual situation met by the medium-sized and large-sized vehicles in the running process, the view angle of the lens of the image pickup device is secondarily corrected through the scale dial and the reference mark, and the direction of the reference mark arranged in the image pickup device pointing to the scale dial is recorded. According to the method, the final calibration of the lens visual angle is carried out through the shooting picture displayed by the external display screen and the actual condition of the vehicle in the driving process, and the calibrated data are recorded.
In a further scheme, the adjustment data recorded in the step f are specifically angle data obtained by calibrating a scale plate in an installation shell and a reference mark line in an image pickup device in advance in the initial installation, and calibration data of the scale plate and the reference mark line recorded after a picture shot after the initial locking of the view angle of a lens in the initial installation is combined with actual conditions encountered in the driving process. The method uniformly installs the imaging devices of all subsequent vehicles through the data recorded in the step d, thereby greatly shortening the time required for installing the imaging devices in batches while ensuring the unchanged manufacturing cost.
According to the visual blind area image pickup device installation method designed by the invention, the image pickup device embedded in the installation shell is rotated according to the scale dial in the installation shell and the reference mark in the image pickup device, the lens view angle of the image pickup device is pre-locked in a smaller interval, so that the time required for final calibration of the lens view angle of the image pickup device is reduced, the lens view angle of the image pickup device is primarily locked, the photographed images are displayed through an external display screen, the lens view angle of the image pickup device is calibrated according to the display images in the external display, and meanwhile, calibrated data are recorded, and then the primary installation angle of the image pickup device of the residual vehicle is recorded according to the recorded scale disc and the reference mark on the installation shell, so that the time required for batch installation of the image pickup device is greatly shortened while the manufacturing cost is ensured to be unchanged.
