Vehicle door control identification system and signal source positioning method, device and product

The invention relates to a vehicle door control recognition system, a signal source positioning method, a signal source positioning device and a product, and the method comprises the steps: obtaining an anchor point coordinate set and an actual measurement distance set corresponding to a current time sequence, the anchor point coordinate set comprises the position coordinates of a plurality of positioning anchor points in a preset coordinate system, the actually measured distance set comprises a first distance from each positioning anchor point to the target signal source; according to the actually measured distance set and the anchor point coordinate set, applying a weighted least square positioning method to determine initial prediction coordinates of the target signal source; based on the initial prediction coordinate, the anchor point coordinate set and the actually measured distance set, iteratively solving an optimized prediction coordinate of the target signal source by applying a Gaussian Newton itera
