Embodiment Construction

[0016] see Figure 1-2 , in one embodiment, a tripod self-propelled vehicle 100 includes a warning sign 1 , a base 2 , wheels 3 installed on both sides of the base 2 , a control system 4 and a binocular camera 5 . The tripod self-propelled vehicle 100 can be used to place behind a predetermined distance (eg, 100 meters, 150 meters) from the vehicle when the vehicle (not shown) breaks down. The control system 4 runs in the tripod self-propelled vehicle 100 and controls the movement of the tripod self-propelled vehicle 100 . The control system 4 includes a memory 40 , a processor 42 and one or more modules, the one or more modules are stored in the memory 40 and executed by the processor 42 to complete the obstacle avoidance function provided by the present invention. The memory 40 can be used to store various data of the tripod self-propelled vehicle 100 , such as storing program codes of the control system 4 . The binocular camera 5 can be fixedly installed on the warning si...

Abstract

An obstacle avoidance method for a tripod self-propelled vehicle, which is applied to a tripod self-propelled vehicle. The obstacle avoidance method includes the following steps: collecting a real-time image ahead of the road to obtain a first image and a second image, wherein the first An image is captured by the left camera in the binocular camera, and the second image is captured by the right camera in the binocular camera; comparing the first image and the second image captured at the same time Obtain the depth value of the obstacle from the binocular camera to the calculation; judge whether the depth value is less than the safety value; if the depth value is less than the safety value, adjust the direction of travel of the tripod self-propelled vehicle to avoid Open the barrier. The invention also provides a tripod self-propelled vehicle. The above-mentioned tripod self-propelled vehicle and its obstacle avoidance method adopt a dual-camera imaging method to detect the depth value of the obstacle in front of it, so that the tripod self-propelled vehicle has an automatic obstacle avoidance function, and the obstacle detection accuracy is high.

Description

technical field [0001] The invention relates to the technical field of traffic warning, in particular to a tripod self-propelled vehicle and an obstacle avoidance method thereof. Background technique [0002] With the improvement of people's living standards, the usage of family cars is increasing day by day. When the temporary failure or traffic accident occurs in the automobile, in order to avoid causing secondary traffic accidents, the automobile is usually equipped with a tripod warning sign to remind other vehicles to avoid in time. The current self-moving tripod warning sign can realize path planning by connecting to the Internet when moving, or move to a preset distance (such as 100 meters, 150 meters) behind the car by calculating the moving distance in real time. However, the existing self-moving tripod warning sign does not have an obstacle avoidance function, which will cause the tripod warning sign to fail to move smoothly to a specified distance due to obstacle...
