The invention discloses a parking space detection method comprising the following steps: obtaining an original image of an environment where a parking space is located, and carrying out distortion correction to obtain a corrected image; carrying out threshold segmentation on the corrected image to obtain a binary image, converting the corrected image from an RGB color space to an HSV color space, carrying out threshold segmentation to obtain an HSV threshold segmentation image, and fusing the HSV threshold segmentation image with the binary image to obtain a fused image; performing edge detection on the fused image to obtain a de-noised edge image; performing straight line detection on the de-noised edge image by adopting Hough transform, and determining a parking space line set based on a set slope difference threshold value and an intercept difference threshold value according to the detected straight line; coordinates of intersection points are determined according to the parking space line set and stored in the parking space line point set, and a parking space coordinate system is established based on the coordinates of the intersection points in the parking space line point set; and determining the parking space according to each point in the parking space line point set and the original point of the parking space coordinate system. The invention further discloses a system, a storage medium and computer equipment.

    本发明公开了一种车位检测方法,包括:获取车位所在环境的原始图像,并进行畸变校正得到校正图像;对校正图像进行阈值分割得到二值化图像,将校正图像由RGB颜色空间转换为HSV颜色空间和阈值分割得到HSV阈值分割图像,并将HSV阈值分割图像与二值化图像进行融合,得到融合图像;对融合图像进行边缘检测,得到去噪边缘图像;采用霍夫变换对去噪边缘图像进行直线检测,根据检测到的直线基于设定的斜率差阈值和截距差阈值确定车位线集;根据车位线集确定交点的坐标并保存在车位线点集中,基于车位线点集中的各交点坐标建立车位坐标系;根据车位线点集中各点与车位坐标系的原点确定车位。本发明还公开了一种系统、一种存储介质和一种计算机设备。
