Splicing error detection method and error detection system for splicing equipment

The embodiment of the invention provides a splicing error detection method and an error detection system for splicing equipment. The method comprises the following steps: acquiring a relative horizontal error equation which takes a first distance and a second distance as independent variables and takes a relative horizontal error as a dependent variable; taking a lower limit distance of a use distance range of the splicing equipment as a first distance, taking an upper limit distance of the use distance range as a second distance, substituting the first distance and the second distance into the relative horizontal error equation to obtain a relative horizontal error, and taking the relative horizontal error as a predicted relative horizontal error, the use distance range is a possible value range of the distance between the splicing equipment and an object needing to be collected in the use process; and determining a splicing error of the splicing device based on the predicted relative horizontal error, the s
