Problems solved by technology

[0005] However, whether it is a reversing radar system or a reversing imaging system, although it provides the driver with information on the distance of obstacles behind the car, and even can see the front, rear, left, and right environmental information through video, the video acquisition device is installed on the car body. The presented image cannot overcome the limitations of the vehicle body itself, and the information cannot fully express the relationship between the vehicle and the surrounding environment. When parking, the driver still needs to rely on his own experience to judge the operation of the vehicle.

Embodiment 1

[0093] Embodiment 1, a kind of parking indication system based on video image processing, such as Figure 9 As shown, including the parking in-position indicating device and the vehicle-mounted device, and the wireless communication between the parking-in-position indicating device and the vehicle-mounted device;

[0094] The parking in-position indicating device is installed above the parking space, and includes a first control unit, a camera connected to the first control unit, a first communication module, a data storage unit, an in-position trajectory prediction module, a parking position indicating module and Speech generating module; the vehicle-mounted device is installed on the vehicle, including a second control unit and a second communication module connected to the second control unit, a storage module, a vehicle steering angle acquisition module, a vehicle gear position acquisition module, a display and a voice output module, the first communication module and the ...

Embodiment 2

[0251] Embodiment 2, based on the parking in-position indication system described in embodiment 1, this embodiment proposes a corresponding parking in-position indication method, which specifically includes:

[0252] (1) After the target vehicle obtains the location of the target parking space, it will go to the target parking space under the guidance of the navigator. When the vehicle reaches the target parking space, the distance is d 1 (d 1 The size of the vehicle can be set to 50 meters), the vehicle-mounted device starts, establishes contact with the parking in-position indicating device through the wireless communication module, and receives the target parking space environment image and the adjacent parking space from the parking in-position indicating device. Use status information, and display it through the display at the same time, the display form is as follows figure 1 shown.

[0253] (2) When the target vehicle continues to drive, the distance to the target par...

Abstract

The invention discloses a parking entry indicating system and an indicating method based on video image processing. The indicating system includes a parking entry indicating device and a vehicle-mounted device. The parking entry indicating device is installed above the parking space. Through image processing and analysis Generate relevant data information of vehicles and parking spaces, and realize the prediction of the target vehicle’s parking trajectory, generate parking criteria and perform real-time judgment and instructions on parking; the vehicle’s steering angle and gear information are obtained by the vehicle-mounted device , and together with the vehicle’s own parameters are sent to the parking indication device to realize the parking space environment information, the real-time relationship data between the vehicle and the parking space, and the real-time display of the vehicle’s parking motion trajectory, combined with voice prompts and display in the form of flashing The warning instructs the driver to park the vehicle quickly and accurately. This solution realizes the comprehensive expression of the relationship between the self-vehicle and the surrounding environment, and gives corresponding instructions according to the driver's real-time parking operation, effectively assisting the driver to complete the parking space safely, accurately and effectively.

Description

technical field [0001] The invention relates to the field of intelligent parking in a parking lot, in particular to a video-based vehicle parking indication system and indication method. Background technique [0002] With the rapid development of my country's economy, more and more cars are owned, and people will inevitably encounter parking problems when driving daily. The difficulty of parking is determined by the driver's parking experience and the complexity of the scene. ease. In order to improve the convenience of the driver's parking and make up for the driver's lack of rear vision, the reversing radar system and the reversing imaging system are successively configured on the vehicle. [0003] The car reversing radar system utilizes the principle of ultrasonic propagation. When parking and reversing, the ultrasonic transmitting probe installed on the rear bumper of the vehicle emits ultrasonic waves, which are reflected back when encountering obstacles during the pro...
