Wireless remote control single-lens vehicle pan-shot system based on mobile communication network

Abstract

The present invention discloses a wireless remote control single-lens vehicle pan-shot system based on a mobile communication network. A mobile control terminal is in wireless connection with a vehicle camera terminal through the mobile communication network or a WiFi wireless network; and the vehicle camera terminal includes a main control module and an image acquisition module, a lens driving module, an image storage module, a sensing triggering module, a module communication module, a wireless WiFi module and a power supply module which are connected with the main control module. The wireless remote control single-lens vehicle pan-shot system based on the mobile communication network is driven by a single lens and a stepping motor to realize the panorama shot and monitoring of the environment in a vehicle and the environment around the vehicle body; the installation is easier, the cost is lower, and because the mobile control terminal is provided with a 3G/4G mobile communication network and the WiFi wireless network, users are convenient to realize wireless and remote operation of a vehicle camera terminal through a mobile control terminal such as a smart phone, a tablet personal computer and the like so as to ensure the vehicle safety.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics and automobile safety wireless monitoring, in particular to a wireless remote control single-lens vehicle panoramic shooting system based on a mobile communication network. Background technique [0002] At present, there are mainly two types of civilian-grade vehicle cameras based on mobile communication networks. One is terminal equipment based on 2.5G mobile communication networks. Due to network bandwidth limitations, it is impossible to transmit smooth on-site video images in real time. Only static photos can be captured at intervals for remote transmission. It is impossible for car owners to understand the current status of the motor vehicle and surrounding scenes in real time and effectively when abnormal situations such as vehicle collisions and intrusions occur. The other type is terminal equipment based on WiFi modules. The vehicle camera is connected to mobile devices such...

[0002] At present, there are mainly two types of civilian-grade vehicle cameras based on mobile communication networks. One is terminal equipment based on 2.5G mobile communication networks. Due to network bandwidth limitations, it is impossible to transmit smooth on-site video images in real time. Only static photos can be captured at intervals for remote transmission. It is impossible for car owners to understand the current status of the motor vehicle and surrounding scenes in real time and effectively when abnormal situations such as vehicle collisions and intrusions occur.

The other type is terminal equipment based on WiFi modules. The vehicle camera is connected to mobile devices such as mobile phones and tablets through the WiFi module to monitor the video images captured by the vehicle camera in real time. However, because WiFi is only a short-range wireless transmission technology, it is limited The connection distance is limited, the owner can only operate within the effective range of the wireless WiFi signal of the device, and cannot realize real remote shooting and monitoring

[0003] The current vehicle-mounted camera achieves panoramic shooting mainly through two methods. The first is to place multiple cameras on one terminal to cover the panoramic range through a fixed viewing angle. Since the viewing angle range of a single camera is limited, at least 3 cameras must be installed on a terminal. Only one camera can achieve panoramic coverage, the disadvantage is that the cost is relatively high

The second is to install four cameras at the front of the car, at the rear of the car, and on both sides of the car body. By switching different camera angles of view or through software, the real-time shooting images of the four groups of cameras are panoramically stitched to achieve panoramic shooting around the car body. The disadvantages are high cost, inconvenient installation, and the inability to take pictures of the situation inside the car
