Description

Reversing photography system

The present invention relates to a photographic technique, and more particularly to a reversing camera system.

With the development of science and technology and the continuous improvement of people's lives, cars have entered the lives of many people, and driving safe cars has become a growing concern. Previously, when driving a car, the rear view method was mainly realized by installing a rear view mirror on both sides of the front of the car. Under the condition of the car rear view device, the rear part of the car body belongs to the driver's "blind zone". However, when the driver reverses the car, if you want to understand the "blind zone" on both sides of the car, you need to turn around and look at the side mirrors. This is easy to happen because the car is not clearly and timely. The wrong situation around the real situation caused the wrong driving, and thus the wrong driving operation, and thus may have serious consequences.

At present, the reversing monitoring device used in the car, from the initial reversing of the rearview mirror, followed by a voice prompt, followed by the use of the ultrasonic sensor reversing radar, and later developed to the photographic display, however, the photographic display system will be installed In a fixed position on the car, this will result in a smaller viewing angle.

In view of this, it is necessary to provide a reversing camera system that can expand the viewing angle.

A reversing camera system includes a guiding member, a processor power supply device, and an imaging device electrically connected to the processor and the power supply device respectively , drive unit and display. The photographing device is movably disposed on the guiding member. The driving device is drivingly connected to the photographing device, the processor controls the driving device to drive the photographing device to move along the guiding member, and the processor displays the image captured by the photographing device in On the display.

Compared with the prior art, the above-described reversing camera system expands the angle of view by moving the image pickup device provided on the guide member.

In order to further explain the reversing camera system of the present invention, the following embodiments will be described in detail below with reference to the accompanying drawings.

Specifically, the processor 150 can be controlled by an operation button near the display screen 140, the driver presses a button, the reverse photography system 100 is activated, and the processor 150 controls the driving device 130 to drive the photography. The device 120 is moved to the desired position along the guiding member 110, thereby expanding the viewing angle, and the image control unit 151 displays the image captured during the moving of the photographing device 120 on the display screen 140, so that the driver can borrow By looking at the display screen 140, you can know the specific situation behind the car.

Second embodiment

Referring to FIG. 3, a reversing camera system 100' provided by the present embodiment is basically the same as the reversing camera system 100 of the first embodiment, and is different. The processor 150' further includes a steering control unit 152' and a gear position sensing unit 153'. The steering control unit 152' is configured to generate a steering signal according to the direction of the steering of the automobile steering wheel, and send the driving signal to the driving device 130', so that the driving device 130' drives the imaging device 120' to move in the direction of the steering signal indication. . The gear position signal sensing unit 153' is configured to receive the signal of the car gear and transmit it to the steering control unit 152' of the processor 150'.

Specifically, if the gear position signal sensing unit 153 ′ receives the signal that the vehicle gear position is the reverse gear, the signal of the reverse gear is input to the steering control unit 152 ′ of the processor 150 ′, the steering control unit 152 ' Further determining the direction of reversing, if the reversing direction is the left rear of the car, the steering control unit 152' transmits the direction to the driving device 130', which drives the camera device 120' to move along the guiding member 110' To the left of the guiding member 110' (to the left of the direction of the car), and to capture the image at that position, the image control unit 151' displays the captured image on the display screen 140'; The direction of reversing is directly behind the car, and the steering control unit 152' transmits the direction to the driving device 130'. The driving device 130' drives the camera device 120' to move along the guiding member 110' to the middle of the guiding member 110'. Positioning, and capturing the image at that time, the image control unit 151' displays the captured image on the display screen 140'; if the direction of the reverse is the right rear of the car, the steering The unit 152' transmits the direction to the driving device 130', and the driving device 130' drives the camera device 120' to move along the guiding member 110' to the right of the guiding member 110' (to the right of the car forward direction), And at this position, the image at the time is taken, and the image control unit 151' The captured image is displayed on the display screen 140'.

The above-mentioned reversing camera system 100' expands the viewing angle by the camera device 120' disposed on the guiding member 110', and is realized by the combination of the gear position signal sensing unit 153' and the steering control unit 152'. In addition, the reversing camera system 100' is activated only in the reverse state to achieve the effect of energy saving, and is started in the non-reversing state to realize real-time monitoring.
