Description

Pair of parking area sensing cameras, a parking area sensing method and a parking area sensing system

The present invention relates to a pair of parking area sensing cameras, parking area sensing methods, and parking area sensing systems, and more particularly to a parking area sensing camera and parking area sensing method, which can reduce hardware cost, reduce installation cost, and increase user convenience. And parking area awareness system.

As shown in Fig. 1, a conventional parking area sensing camera is usually installed directly above the parking space to be sensed, and the body itself contains an indicator light. A parking area A contains at least one parking space, such as parking space A1, parking space A2, and parking space A3. The installation method usually installs one camera in one or two parking spaces. When the parking area sensing camera detects that at least one of the parking spaces is vacant, it will display a green light, otherwise it will display a red light. Because the distance between the parking area sensing camera and the parking area to be perceived is short, the parking area sensing camera cannot capture a wide range of parking areas. Therefore, each parking area senses that the camera can detect a small number of vehicles, and at most Sensing one or two parking spaces.

In addition, as shown in FIG. 2, there are also known parking area sensing photography frames located above the middle of the lane, and each camera has two lenses for respectively photographing the parking spaces on the left and right sides of the lane, when the camera detects at least one of the parking spaces. When the parking space is empty, a green light will be displayed, otherwise a red light will be displayed. Because the two lenses need to be integrated into a single body, the disadvantage of this design is that the hardware and mechanism of the camera are complicated. And because of the need to deal with two image sources, another disadvantage of this design is that the firmware and software of the camera are more complicated. In addition, the car can not be judged by the signal to determine whether the vacancy is on the left or right side of the lane. Moreover, similar to the conventional parking area sensing camera described above, the distance between the parking area sensing camera and the parking area to be perceived is also close, so that the number of vehicles that each camera can sense is not much.

One of the objects of the present invention is to provide a parking area sensing camera, a parking area sensing method, and a parking area sensing system, which can reduce hardware cost, reduce installation cost, and increase user convenience, to solve the above problems.

According to an embodiment, the parking area sensing camera of the present invention comprises: a first parking area sensing camera, monitoring a first parking area to generate a parking state of a first parking area; and a second parking area sensing camera, Monitoring a second parking area to generate a parking state of a second parking area; wherein the first parking area sensing camera is configured to display a parking status of the second parking area.

According to another embodiment, the parking area sensing method of the present invention includes: using a first parking area sensing camera to monitor a first parking area to generate a parking state of a first parking area; using a second parking area to sense a camera monitoring A second parking area is seen to generate a parking state of the second parking area; and the first parking area sensing camera displays the parking status of the second parking area.

According to another embodiment, the parking area sensing system of the present invention comprises: a parking lot having a first parking area and a second parking area; a first parking area sensing camera, monitoring a first parking area to generate a first a parking state of a parking area; a second parking area sensing camera, monitoring a second parking area to generate a parking state of a second parking area; wherein the first parking area sensing camera is configured to display the second parking area Parking status.

In summary, the present invention improves the shooting range of the camera, reduces the total number of cameras, and reduces the camera shooting range by sensing the position of the camera in the paired parking area and sensing the parking area to sense the parking position of the camera. System cost. Moreover, since the field of view of one lens can include more parking spaces, it is not necessary to use a dual lens, which reduces the cost of the camera. Moreover, the car driving can directly determine whether the empty parking space is on the left side or the right side by the light number, which is convenient for the user.
