Detection device, scanning unit, movable platform, and control method of detection device

Abstract

A detection device (100) comprises a light source (10), a first scanning module (20) and a second scanning module (30). A light source (10) for emitting a sequence of light pulses; the first scanning module (20) and the second scanning module (30) are arranged on a light path of the light pulse sequence, the first scanning module (20) is used for changing the propagation direction of the light pulse sequence, and the first scanning module (20) can independently enable the emergent light beam to scan along a first path; the second scanning module (30) comprises a reflecting module (31) and a driving module (32), the reflecting module (31) comprises at least two reflecting surfaces (311), and the driving module (32) is used for driving the reflecting module (31) to rotate, so that the at least two reflecting surfaces (311) sequentially rotate to a light path of the light pulse sequence, and the detection device (100) scans in the two-dimensional direction. Therefore, the reliability of the detection device (100) is improved, and the cost is reduced. The invention also relates to a scanning unit, a movable platform and a control method.

Description

technical field

[0001] The present application relates to the technical field of detection equipment, and in particular, to a detection device, a scanning unit, a movable platform, and a control method of the detection device. Background technique

[0002] The application of detection equipment in autonomous driving scenarios generally requires a horizontal field of view of more than 100°, a long-distance range, high scanning density, and a uniform scanning trajectory. In traditional detection equipment, more light emitters are arranged on the vertical field of view, and the light emitters are driven to rotate on the horizontal field of view by driving a motor, so as to achieve a larger coverage in the horizontal field of view. However, this detection device requires many light emitters, has low reliability and high cost. SUMMARY OF THE INVENTION

[0003] The present application provides a detection device, a scanning unit, a movable platform and a control method of the d...
