DETECTION SYSTEM, TERMINAL DEVICE AND DETECTION CONTROL METHOD

A detection system, a terminal device, and a detection control method are provided, to resolve a problem of low detection accuracy of a detection system in the conventional technology, and are used in fields such as autonomous driving, intelligent driving, assisted driving, or networked vehicles. The detection system includes a transmit module, a receive module, a first scanning module, and a second scanning module. An included angle between a first normal vector of a first reflective surface of the first scanning module and a second normal vector of a second reflective surface of the second scanning module is a first angle greater than 0 degrees. The first reflective surface and the second reflective surface are adjacent reflective surfaces. An included angle between an optical axis of the transmit module and an optical axis of the receive module is a second angle greater than 0 degrees. The transmit module is configured to transmit signal light, the first scanning module is configured to reflect the received signal light, the second scanning module is configured to reflect, to the receive module, an echo signal obtained by reflecting the signal light by at least one target, and the receive module is configured to receive the echo signal. Based on this, detection accuracy of the detection system can be improved.
