Problems solved by technology

However, in the real environment, there are often some obstacles on the roadside, and the detection results returned by roadside obstacles will affect the vehicle's detection of the distance between itself and the edge of the road, which can be regarded as abnormal detection results

Embodiment Construction

[0052] Based on the understanding of the above problems, this manual provides a distance measurement method, by calculating the passive movement speed of the target device towards the detection surface, filtering out abnormal detection results, and realizing stable distance measurement on the detection surface.

[0053]The ranging method provided in this manual can be used for any target device to measure the distance of the detection surface. In , when the drone is flying, the detected distance is the ground-to-ground height between the drone and the ground. Among them, the unmanned aerial vehicle can be a delivery unmanned aerial vehicle in the field of distribution, especially for food delivery.

[0054] In the following parts of this manual, the area with a gentle change in height is regarded as the ground in this manual. Figure 2B In , the ground is shown by the dotted line, while Figure 2B The tree heights shown in Figure 2B Trees are shown in as obstacles on the g...

Abstract

The invention discloses a distance measuring method and device, a storage medium and electronic equipment. After the first detection value of the detection equipment is obtained, the relative movement speed of the target equipment towards the detection surface is determined according to the first detection value, and the passive movement speed reflecting the height change degree of the detection surface can be determined according to the relative movement speed and the active movement speed of the unmanned aerial vehicle towards the direction of the detection surface. And the first detection value is screened according to the passive movement speed, so that a detection result returned by an obstacle with violent height change is filtered out, and stable distance measurement is realized.

Description

technical field [0001] This specification relates to the technical field of distance measurement, and in particular to a distance measurement method, device, storage medium and electronic equipment. Background technique [0002] At present, ranging technology has been applied in more and more fields. More commonly, the radar mounted on the vehicle can provide assistance to the driver by detecting the distance between surrounding obstacles and the vehicle. [0003] In some applications, when the detection device detects the detection surface, the returned detection results may include abnormal detection results that affect the detection effect. For example, in figure 1 In the scene shown, the radar mounted on the vehicle body detects the detection surfaces located on both sides of the vehicle, and determines the position of the vehicle in the road coordinate system in real time according to the detection results returned by the radar. At this time, the required detection res...
