本发明解决了现有技术中检测成本高或检测准确率偏低的不足，提供一种基于计算机视觉技术判断停车位是否空闲的停车位检测方法，包括：各个停车位分别设定辅助识别图案、将辅助图像对应区域设置为视频检测区域、记录各个检测区域在停车位空闲时的图像色彩游程编码，进行停车位空闲检测时分别对图像中各个检测区域进行像素扫描分析、获得各检测区域的图像色彩游程编码、对比各个检测区域的图像游程编码与停车位空闲时是否匹配，若特征一致，则该停车位空闲，否则该停车位忙碌，其有益效果是辅助识别图案在不同光照环境中具有图像色彩组合模式一致性，在直接利用监控系统的视频图像进行停车位车辆存在性检测时具有较高的准确率。
The invention discloses a parking space detection method which judges whether a parking space is free or not based on computer vision technology and solves the defects that in the prior art, detection cost is high and detection accuracy is low. The free parking space detection method based on the computer vision comprises the steps that an auxiliary recognition image is respectively arranged in each parking space, areas correspond to the auxiliary images are arranged to be video detection areas, image color run length codes of all detection areas when the parking spaces are free are recorded, pixel scan analysis is conducted to all the detection areas in the images during parking space free detection, image color run length codes of all the detection areas are obtained, and the image color run length codes of all the detection areas are compared with those when the parking spaces are free to judge whether the features are matched, and if the features are uniform, the parking spaces are free, otherwise the parking spaces are busy. The parking space detection method based on the computer vision technology has the advantages that the auxiliary recognition images have image color composite mode uniformity in different light environments, and when video images of a monitoring system are directly used for conducting parking space vehicle existence detection, high accuracy is achieved.
