Embodiment 1

[0043] This embodiment discloses an intelligent car-finding method in a parking lot based on vehicle body CAN data and terminal applications, such as figure 1 shown, including:

[0044] S10. Collect the front video signal during the driving process of the vehicle whose speed is within a certain range, and transmit it to the cloud server to identify the entrance and exit gate of the parking lot directly in front of the vehicle.

[0045] This step specifically includes:

[0046] S101. Determine the vehicle speed. When the vehicle speed is less than or equal to the first preset threshold, the video recognition unit installed on the vehicle side collects the video signal directly in front of the vehicle in real time, and sends it to the cloud server through the communication transmission module installed inside the vehicle.

[0047] Alternatively, this step can also be: collecting the front video signals during the driving process of the vehicle in real time, screening out the fr...

Abstract

The invention relates to a parking lot intelligent vehicle searching method based on vehicle body CAN data and terminal application. The method comprises the following steps: collecting a right ahead video signal of a vehicle with a vehicle speed within a certain range in a driving process, and transmitting the right ahead video signal to a cloud server, so as to recognize a parking lot entrance and exit barrier gate right ahead of the vehicle; enabling the vehicle to obtain vehicle body CAN data in real time and transmit the vehicle body CAN data to the cloud server, and enabling the mobile terminal to obtain gyroscope data and accelerometer data and send the gyroscope data and the accelerometer data to the cloud server; enabling the cloud server to generate a driving track diagram of the vehicle in the underground parking lot and a walking track diagram of a vehicle owner according to the vehicle body CAN data and the mobile terminal data; and sending to a mobile terminal application to generate a complete navigation route map. The position of the vehicle in the parking lot is determined only through the vehicle body CAN data and the mobile terminal data without depending on a GPS signal of the underground parking lot and other equipment, so that a vehicle owner can quickly find the vehicle and the entrance and exit of the parking lot, and the problem that the vehicle owner is difficult to find the vehicle and the exit is solved.

Description

technical field [0001] The invention relates to the technical field of parking lot management, in particular to an intelligent car-finding method in a parking lot based on CAN data of a vehicle body and terminal applications. Background technique [0002] In the underground space, especially the underground space of public places such as large-scale shopping malls and large-scale entertainment in cities, the parking lot in the underground space generally has a large construction scale, the traffic organization and spatial layout are relatively complicated, and the car owners are unfamiliar with the parking area in the underground space. Many factors make it difficult for car owners to find a car after parking. [0003] At this stage, there are many solutions for indoor positioning technology, but there are not too many solutions that can be used as consumer-level technical solutions. At present, the commercial indoor positioning solutions based on lightweight sensors and mob...
