Description

Technical Field

[0001] The utility model relates to the technical field of vehicle obstacle perception, in particular to a camera for four-way shuttle vehicle obstacle perception. Background Art

[0002] The four-way shuttle obstacle perception camera is a special-purpose camera, mainly used for obstacle perception of four-way shuttles in automated logistics systems. The four-way shuttle is a mechanical device that can shuttle in all directions between warehouse shelves to transport and store items. During operation, the four-way shuttle needs to avoid obstacles such as shelves and walls, otherwise it may cause collisions and damage.

[0003] When using a four-way shuttle to transport items, we found that the existing four-way shuttle cannot avoid obstacles and is prone to collisions. Therefore, we proposed a camera for obstacle perception on a four-way shuttle. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0005] Specifically, the technical problem to be solved by the present invention is to provide a camera for obstacle perception of a four-way shuttle vehicle, so as to solve the technical problem that the existing four-way shuttle vehicle cannot avoid obstacles and is prone to collision.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A camera for obstacle perception of a four-way shuttle vehicle, comprising: a camera group, the camera group consisting of a plurality of high-precision cameras, the cameras being arranged on the side of the four-way shuttle vehicle and used to collect image information of the vehicle's surrounding environment;

[0008] A sensor group, comprising a plurality of high-precision sensors, disposed on the sides of the four-way shuttle vehicle and configured to sense target information of obstacles surrounding the vehicle;

[0009] A central processing unit is connected to the camera group and the sensor group respectively, and is used to receive image information, target information and speed information to determine obstacles close to the vehicle body.

[0010] As an improved technical solution, at least two of the cameras are arranged relative to each other so that the detection directions of the at least two cameras are different, and the detection ranges of the at least two cameras partially overlap. The cameras can obtain environmental images within the vehicle's own lateral blind spot and promptly identify obstacles close to the vehicle.

[0011] As an improved technical solution, at least two of the sensors are arranged relative to each other so that the detection directions of the at least two sensors are different and the detection ranges of the at least two sensors partially overlap. The sensors are used to detect obstacles in advance and assist the camera in identifying close-range obstacles.

[0012] As an improved technical solution, the central processor is also connected to the braking system of the four-way shuttle vehicle for timely braking.

[0013] As an improved technical solution, the central processing unit includes a storage module for storing position information of the camera group and the sensor group.

[0014] As an improved technical solution, the central processor is also connected to the electronic control unit of the four-way shuttle vehicle to send specific information about the obstacle to the electronic control unit.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] The utility model obtains the final specific information of the obstacle after the central processing unit fuses the image information, the target information and speed information of the obstacle and the position information of the camera group and the sensor group, and sends the fused obstacle information to the electronic control unit. The electronic control unit judges the impact of the obstacle on the travel of the four-way shuttle vehicle based on the obstacle information, and then sends braking information to the braking system of the four-way shuttle vehicle. If the obstacle is sensed, it is avoided in time or braked to stop in time, so as to achieve the effect of sensing the obstacle and avoiding or braking in time to avoid collision, so that the obstacle can be sensed and avoided, and the brakes can be applied in time to avoid collision.
