The invention discloses a portal crane mounting method which comprises the following steps: S1, lifting a main beam to a first height, acquiring a first mounting image, identifying the main beam in the first mounting image, and calculating the offset of the main beam; s2, if the offset is smaller than the first threshold value, one side of the upper end of each supporting leg is hinged to the main beam, and one side of the lower end of each supporting leg is hinged to a sliding trolley; s3, the main beam is lifted to a second height, a second installation image is obtained, a supporting leg in the second installation image is recognized, and the inclination angle of the supporting leg is calculated; s4, if the inclination angle is within the preset range, continuing to lift the main beam to a third height, and obtaining a third installation image; s5, identifying a supporting leg and a main beam in the third installation image, and calculating an included angle of a hinged part of the supporting leg and the main beam; and S6, if the included angle is smaller than a second threshold value, the supporting leg and the main beam are welded. The mounting process can be controlled, and the mounting precision is guaranteed.

    本发明公开了门式起重机安装方法,包括:S1:提升主梁至第一高度,并获取第一安装图像,识别第一安装图像中的主梁,计算主梁的偏移量;S2:若偏移量小于第一阈值,则将支腿上端一侧与主梁铰接,并使下端一侧与一滑移小车铰接;S3:提升主梁至第二高度,并获取第二安装图像,并识别第二安装图像中的支腿,计算支腿的倾角;S4:若倾角在预定范围内,则继续提升主梁至第三高度,并获取第三安装图像;S5:识别第三安装图像中的支腿和主梁,计算支腿和主梁铰接部位的夹角;S6:若夹角小于第二阈值,则将支腿与主梁焊接。本发明能够对安装过程进行控制,保证安装精度。
