Problems solved by technology

[0003] The normal charging time of electric vehicle batteries is much longer than the refueling time of gasoline passenger vehicles. Therefore, providing fast battery replacement services for electric vehicles will be an important business content of charging and replacement facilities. However, due to the heavy weight of electric vehicle battery packs , the rapid battery replacement business cannot be effectively promoted only by manual battery replacement

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation. Such as figure 1 As shown, it is a schematic diagram of the layout of the stereo vision battery positioning method. The electric vehicle battery visual positioning method of the present invention, its specific process is:

[0027] (1) Image acquisition:

[0028] figure 2 It is the front view of the image acquisition device of the vision system. The image acquisition device is composed of a single-chip microcomputer 1, a cylinder 2, a camera and a mechanical shutter 3, a supplementary light 4, and a power supply 5. The single chip provides feedback signals for trigger switch, synchronous switch, distance measuring and other devices for the software system. The fill light between the left and right cameras provides a stable light source for the vision system.

Abstract

The invention relates to the field of machine vision, in particular to a stereoscopic-vision-based location method for electric vehicle batteries. Two synchronous sampling images are acquired by a binocular stereo image acquisition unit and a stereoscopic-vision precision synchronous switch device. The mechanical shutter device proofs water and dust. A single-chip microcomputer is used for light measurement and control parameter adjustment. LED light supplement is triggered by a mechanical shutter, so that stable-light sampling images are obtained. After battery location is over, compensating is performed according to ranging data of a sensor. The method is free of projecting active information to a car, bonding a location mark to a car body, installing the sensor on the car body, and highly requiring uniformity on the shape and size of battery frames for the same type of cars. Location accuracy is insusceptible to certain dirtiness of car body and battery surface and changes of external environmental conditions.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to an electric vehicle battery positioning method based on stereo vision. Background technique [0002] Compared with traditional fuel vehicles, electric vehicles have the advantages of zero emission, low noise, high energy efficiency, low operation and maintenance costs, etc., and have obvious advantages in cleanliness, environmental protection, and energy saving. The power source of the electric vehicle is the power storage battery installed inside the vehicle body. When the power of the power battery is consumed to a certain extent, it must be supplemented with energy to ensure the continuous use of the electric vehicle. One of the most important energy supply methods for electric vehicles is battery replacement. Battery replacement refers to replacing the depleted power battery on the electric vehicle with a fully charged power battery to complete the power supplement. [0003] T...
