The invention relates to a target state estimation method, which comprises the following steps of: acquiring observed quantities of a target at various moments through various sensors, and acquiring at least one observed quantity through each sensor; determining a to-be-optimized state quantity of the target based on the observed quantity; and optimizing the state quantity of the target at each moment by minimizing the loss function to obtain the optimized state quantity of the target at each moment. The loss function comprises at least one of position loss, orientation loss, speed loss, size loss and structural constraint of the target. According to the target state estimation method disclosed by the invention, enough accurate state estimation can be obtained. In addition, the invention also provides a target state estimation device, electronic equipment and a medium.
