1. A mistie detection system comprising:
a square baler configured to form square bales from crop material, wherein said baler includes a baling chamber configured to compress crop material into bales and a knotter assembly configured to tie securement lines around the bales,
wherein the knotter assembly comprises a first knotting mechanism and a second knotting mechanism, each being configured to tie a securement line around the bales, such that the knotter assembly is configured to tie two securement lines around the bales;
image sensors mounted to said baler and configured to monitor the securement lines and the bales; and
a control system configured to process image data from said image sensors to determine if a mistie event has occurred,
wherein said image sensors comprise a first image sensor and a second images sensor aimed towards an interior of said baling chamber, wherein the first image sensor is configured to obtain images or video of knots of a first of the two securement lines having been tied onto the bales, and wherein the second image sensor is configured to obtain images or video of knots of a second of the two securement lines having been tied onto the bales,
wherein said control system is configured to determine if a mistie event has occurred by analyzing the images or videos of the knots of the securement lines having been tied around the bales.
