s101, judging whether a first touch point is detected.
In the optical network formed by the infrared emission device and the infrared receiving device, when the shielding area is not scanned, the cyclic scanning is carried out consistently. The cyclic scanning may be that scanning is sequentially performed from a first infrared emitting device of the X axis to a last infrared emitting device of the Y axis, so as to complete one cycle of scanning, for example, the first infrared emitting device of the X axis scans one-to-one and the infrared receiving device of the right diagonal coordinate until the last infrared emitting device of the Y axis and the right diagonal coordinate are scanned, then the first infrared emitting device of the X axis emits infrared light of the left diagonal coordinate, the corresponding infrared receiving device collects infrared information until the last infrared emitting device of the Y axis and the infrared light of the left diagonal coordinate are collected, the corresponding infrared receiving device collects infrared information, and finally the first infrared emitting device of the X axis emits infrared light of the right diagonal coordinate, the corresponding infrared receiving device collects infrared information until the last infrared emitting device of the Y axis and the right diagonal coordinate are infrared light, and the corresponding infrared receiving device collects infrared information, so as to complete one cycle of scanning; for another example, infrared light rays of all angles are emitted from the first infrared emission device of the X axis, and corresponding infrared information is collected by the corresponding infrared receiving device until the last infrared emission device of the Y axis scans, so that one period of scanning is completed. The present embodiment is not limited to the scanning method, and may be set by a user in a user-defined manner as long as the purpose of the present embodiment can be achieved.
Further, whether the first touch point is detected is determined, but the detection mode is not limited in this embodiment, and the first touch point may be used only if there is touch information, or may be used only if the touch point reaches a certain condition, for example, when the width of the touch point is greater than a preset width threshold, the first touch point may be used as a false hand when the width of the touch point is less than the preset width, and further, the first touch point may be cleared, or may be considered as a false hand when the width of the touch point is less than the preset time, according to the touch time of the touch point.
S102, if the first touch point is detected, a first preset scanning area is obtained according to first touch point information of the first touch point.
If the first touch point is detected, a first preset scanning area is obtained according to first touch point information of the first touch point. The purpose of this step is to perform a predetermined operation to obtain a first preset scan area. The first touch point information comprises coordinate information, touch time, touch force and the like of the touch point. The first preset scanning area may be a preset area range, or may be an area range determined according to the first touch point information. For example, if the coordinate information of the touch point is (X, Y), the first preset scanning range is (X-n) 1 ，Y-m 1 )、(X-n 1 ，Y+m 2 )、(X+n 2 ，Y-m 1 )、(X+n 2 ，Y+m 2 ) At this time, n 1 、m 1 、n 2 、m 2 Any one or more of the items may be equal or different, and this embodiment is not described in detail, and the user may customize the setting. The area range determined according to the first touch point information may be that when the coordinate information in the first touch point information is within a preset range, n corresponding to the preset range can be directly obtained 1 、m 1 、n 2 、m 2 Values.
And S103, when the first preset scanning area is scanned, acquiring a second touch point in the first preset scanning area and corresponding second touch point information.

The second touch point information comprises coordinate information, touch time, touch force and the like of the second touch point.
Specifically, in this embodiment, after a preset operation is performed, a first preset scanning area is actively calculated and issued to a scanning sampling module, and after the scanning sampling module receives the first preset scanning area, signal scanning and acquisition are performed on an infrared transmitting device and an infrared receiving device of the first preset scanning area, as shown in fig. 2 below, fig. 2 is a schematic diagram of an external information acquisition method provided in an embodiment of the present application, and regional scanning and signal acquisition are performed in the first preset scanning area, so as to implement calculation and tracking of the point.
Further, after obtaining the second touch point in the first preset scanning area and the corresponding second touch point information, the method further includes:
detecting whether the second touch point is lifted;
if the touch point is not lifted, acquiring a third touch point and corresponding third touch point information in the second preset scanning area when the second preset scanning area is scanned, and circulating until the touch point is lifted, wherein circulating scanning is performed at the moment.
And S104, if the first touch point is not detected, performing cyclic scanning.
Based on the above technical solution, in this embodiment, by detecting the first touch point, a first preset scan area is obtained according to first touch point information of the first touch point; when the first preset scanning area is scanned, tracking of the first touch point is achieved by the mode of acquiring the second touch point in the first preset scanning area and the corresponding second touch point information, the first preset scanning area is scanned in a targeted mode, time consumption caused by data transmission after the infrared scanning sequence is completed in the related art is avoided, touch delay is reduced, touch response and transmission speed are improved, point reporting rate is improved, and user experience is improved.
Based on the above embodiments, the present embodiment provides another method for collecting infrared information, before determining whether a first touch point is detected, including: determining infrared receiving devices corresponding to the infrared emitting devices; and switching and scanning the infrared emission device and all corresponding infrared receiving devices according to a preset sequence.
Based on the above technical scheme, the embodiment performs switch scanning through the infrared emission device corresponding to all the infrared receiving devices so as to complete scanning of all the infrared emission devices, therefore, the infrared emission devices only need to be turned on normally and on once in the whole scanning process, and acquisition of all signals can be completed in one period, so that the related scanning addressing time and the time of switching the infrared emission devices are saved, the scanning sampling speed is improved, and the touch control delay is reduced.
