Fuel tank fuel quantity detection method and device, fuel tank, T-box and vehicle

The invention relates to a fuel tank fuel quantity detection method and device, a fuel tank, a T-box and a vehicle. The method comprises the steps that an internal image of the fuel tank is acquired; determining the relative position of an oil mark boundary line of the inner wall of the oil tank and a reference pattern coated on the inner wall of the oil tank in the internal image; according to the relative position of the oil mark boundary line and the reference pattern, space reconstruction is conducted on fuel oil in the oil tank; and calculating the oil quantity in the oil tank according to the reconstructed space. By means of the technical scheme, even if the vehicle runs on a road surface with a large slope or a bumpy road surface and the oil tank inclines, the remaining oil amount in the oil tank can be accurately calculated. 本公开涉及一种油箱油量检测方法、装置、油箱、T-box及车辆，所述方法包括：获取油箱的内部图像；在所述内部图像中确定所述油箱内壁的油迹边界线与所述油箱内壁涂布的参照图案的相对位置；根据所述油迹边界线与所述参照图案的相对位置，对所述油箱内的燃油进行空间重构；根据重构的空间计算所述油箱内的油量。通过上述技术方案，即使车辆行驶在坡度较大或较颠簸的路面上，油箱发生
