[0094] see figure 1 , which is a schematic flowchart of a vehicle position detection method provided in this embodiment, the vehicle position detection method includes the following steps:
[0095] S101: Acquire a real image of an area in front of the target vehicle captured by an image acquisition device installed on the target vehicle, wherein the real image is an image captured by the image acquisition device at a current moment with a fixed viewing angle.
[0096] For ease of description, in this embodiment, the vehicle driven by the driver is referred to as the target vehicle.
[0097] In this embodiment, an image acquisition device may be installed on the target vehicle in advance, for example, the image acquisition device may be a camera, specifically a monocular planar camera. see figure 2 As shown, an image acquisition device can be installed on the front of the target vehicle, and of course it can also be installed on the roof, so that the image acquisition device...

[0109] This embodiment will introduce the specific implementation of step S102 in the first embodiment, specifically how to detect the position information of the vehicle in front of the left side of the target vehicle.
[0110] In this embodiment, the preset angle in the above step S102 may be a first angle, and the first viewing angle may be the viewing angle after the fixed viewing angle is rotated counterclockwise by a first angle in the horizontal direction, based on this , if the preset angle is the first angle, the vehicle on the side of the target vehicle is the vehicle on the left side of the target vehicle.
[0111] In this embodiment, real images captured at a fixed viewing angle are presented with a left viewing angle different from the fixed viewing angle, and this embodiment is referred to as a first viewing angle. In order to facilitate the understanding of the first viewing angle, an example is now used to illustrate that the first viewing angle may be figure...

[0181] This embodiment will introduce the specific implementation of step S102 in the first embodiment, specifically how to detect the position information of the vehicle in front of the right side of the target vehicle.
[0182]In this embodiment, the preset angle in the above step S102 may be a second angle, and the second viewing angle is the viewing angle after the fixed viewing angle is rotated clockwise by a second angle in the horizontal direction. Based on this, If the preset angle is the second angle, the vehicle on the side of the target vehicle is the vehicle on the right side of the target vehicle.
[0183] In this embodiment, a real image captured at a fixed viewing angle is presented with a right viewing angle different from the fixed viewing angle, and this embodiment is referred to as a second viewing angle. In order to facilitate the understanding of the second viewing angle, an example is given to illustrate that the second viewing angle can be figure 2 The...
