This application discloses a calibration method, a calibration system, and a calibration board. The calibration board includes checkerboard cells arranged on a surface of the calibration board, where at least one dot is arranged in each of the checkerboard cells, the dots of the calibration board include at least a first feature dot and a second feature dot, the first feature dot and the second feature dot are arranged in the checkerboard cells according to a random rule or a specific rule, and a diameter of the first feature dot is greater than a diameter of the second feature dot. The calibration board in this application improves the stability and accuracy of calibration board detection by utilizing characteristics such as a high detection accuracy and a strong anti-blur capability of a dot mark, combining with corner points of checkerboard cells.

Calibration board and calibration method and system

The present disclosure provides a vehicle, a start control method for the vehicle, and a start control system of the vehicle. The method includes: when a door of the vehicle is in an open state, determining a position of a key; when the key is in the vehicle, controlling a first high-voltage module group of the vehicle to perform power on; when the door of the vehicle is changed from the open state to a closed state, determining the position of the key and detecting a state of a brake pedal of the vehicle; and when the brake pedal of the vehicle is depressed and the key is in the vehicle, controlling, according to a start instruction, a second high-voltage module group of the vehicle to perform power on.

Vehicle, start control method for vehicle, and start control system of vehicle

The present disclosure discloses a vehicle and a vehicle security control method and system based on an open platform. The open platform includes a software development kit in which a control protocol is encapsulated, the software development kit provides an API function interface, and the method includes: receiving a call request from a third-party device for a target API function interface of the open platform; converting the call request by using the software development kit to generate a control signal that meets a requirement of the control protocol and that is used for controlling a first vehicle component in a vehicle; and transmitting the control signal to a security gateway through a first bus, to enable the security gateway to perform protocol conversion on the control signal, and transmitting the control signal to an in-vehicle network to control the first vehicle component in the vehicle.

Vehicle and vehicle security control method and system based on open platform

The present invention provides a method for selecting a working remote radio unit for a user equipment. By comparing isolation of a current working RRU set of a user equipment with a preset isolation threshold, resource utilization and signal interference can be effectively balanced and a working remote radio unit of the user equipment can be accurately determined.
