[0004] However, the previous ECU can only grasp the physical address of the camera from the data received and sent by the camera, and cannot know the port or installation location of the lower link of the Ethernet switch to which the camera is connected.
[0005] Therefore, it is difficult for the conventional ECU to grasp the camera that sent the corresponding data from the physical addresses contained in the data of multiple cameras.

The present invention relates to a camera position determination apparatus and method. One aspect of the present invention is the camera position discrimination apparatus, comprising: a plurality of switches, a control unit, an Ethernet switch, and an ECU (electronic control unit). When the switches are closed, the power supplies from a power supply unit are respectively supplied to a plurality of Ethernet cameras. The control unit controls the close or disconnection of the plurality of switches. The inferior link of the Ethernet switch is connected with the plurality of Ethernet cameras and the control unit. ECU is connected with the superior link of the Ethernet switch. In the position determination step, the ECU enables the plurality of switches to be closed one by one through the control unit based on the sequence corresponding to the set fixation locations. Meanwhile, in the plurality of Ethernet cameras, the MAC address of the Ethernet cameras is mastered from the closed switches of the plurality of switches to receive the power supply and be started. The mastered MAC address is associated with the fixation locations. After the implementation of the position determination step, the fixation locations of the Ethernet cameras sending the data are determined from the MAC address included in the data of the Ethernet cameras.
Description
technical field [0001] The invention relates to a camera position judging device, in particular to a camera position judging device and method capable of judging the positions of multiple cameras connected to an Ethernet switch. Background technique [0002] Generally speaking, when installing multiple cameras on the vehicle, use an Ethernet camera with a relatively simple interface, and connect multiple Ethernet cameras to the ECU through an Ethernet switch. [0003] The ECU is connected to the upper link of the Ethernet switch, communicates with a plurality of cameras connected to the lower link of the Ethernet switch, and controls the cameras or receives image data from the cameras. [0004] However, the conventional ECU can only grasp the physical address of the camera from the data received and sent from the camera, and cannot know the port or installation location of the lower link of the Ethernet switch to which the camera is connected. [0005] Therefore, it is diff...
