Touch detection method and apparatus, electronic device, and readable storage medium

A touch detection method, comprising:

• determining at least one touch area according to sampled values of capacitive sensing nodes of a touch screen;
• performing, according to the sampled values of each of the at least one touch area and position information of each of the at least one touch area, target restoration processing on the sampled values in each of the at least one touch area to determine target values of the capacitive sensing nodes in each of the at least one touch area;
• determining a peak point of the target values in each of the at least one touch area according to the target values of the capacitive sensing nodes in each of the at least one touch area;
• and
• determining a valid touch area according to a preset touch threshold and the peak point of the target values in each of the at least one touch area, wherein
• before the performing, according to the sampled values of each of the least one touch area and position information of each of the least one touch area, target restoration processing on the sampled values in each of the at least one touch area to determine target values of the capacitive sensing nodes in each of the least one touch area, the method further comprises:
• extending an edge of each of the at least one touch area toward a surrounding area by a preset number of layers of capacitive sensing nodes to obtain a first target area corresponding to each of the at least one touch area;
• and
• performing, according to the sampled values of each of the at least one touch area and the position information of each of the at least one touch area, target restoration processing on the sampled values in the first target area to obtain a target value of each capacitive sensing node in the first target area, wherein the first target area comprises the touch area, and the first target area comprises N columns of capacitive sensing nodes, and N is a positive integer.
