step S102, collecting infrared light spots through an infrared camera, wherein the infrared light spots are formed by reflecting infrared rays through a target object contacting a projection area, and the projection area is obtained by projecting the infrared light spots to the target area through a projection device;
step S104, determining the size of the infrared light spot, and identifying whether the contact of the target object to the projection area is an effective contact operation according to the size of the infrared light spot.
According to the application, the infrared camera is used for collecting the infrared light spots, wherein the infrared light spots are formed by reflecting infrared rays through a target object contacting a projection area, and the projection area is obtained by projecting the infrared light spots to the target area through the projection device; and determining the size of the infrared light spot, and identifying whether the contact of the target object to the projection area is an effective contact operation according to the size of the infrared light spot. Therefore, the problem that invalid contact operation of an interfering object cannot be identified in the related technology can be solved, the identification accuracy of the contact operation is improved, and the user experience is optimized.
In the above embodiment, before the collecting the infrared light spot, the method further includes: and projecting the target area through the projection device to obtain the projection area, and transmitting an infrared light beam to the projection area through an infrared laser transmitter. As an alternative embodiment, the projection device may be an ultra-short Jiao Guangji, for example, by projecting the ultra-short Jiao Guangji onto the target area to form a projection area, and by emitting an infrared beam of light onto the projection area by an infrared laser emitter, the infrared light being reflected by the target object when the target object contacts the projection area, the emitted light forming an infrared spot, which is then captured by an infrared camera.
The size of the infrared light spot may be the diameter or the area of the infrared light spot, or the size of the infrared light spot may be the width of the infrared light spot when the infrared light spot is in a band shape.
Based on the above embodiment, the identifying whether the contact of the target object to the projection area is a valid contact operation according to the size of the infrared light spot includes: determining that the contact of the first object to the projection area is an ineffective contact operation under the condition that a first light spot exists in at least one infrared light spot; the size of the first light spot is smaller than or equal to a first threshold value or larger than or equal to a second threshold value, the first light spot is formed by reflecting the infrared rays through the first object contacting the projection area, and the target object comprises the first object.
Under the condition that a first light spot with the size smaller than or equal to a first threshold value or larger than or equal to a second threshold value exists in infrared light spots collected by an infrared camera, determining that a first object corresponding to the first light spot is an interfering object, the first light spot is an invalid light spot, and the contact of the first object to a projection area is an invalid contact operation, so that the identification of the invalid contact operation of the interfering object is realized, the influence of the interfering object on the touch operation is avoided, the accuracy of the touch operation is improved, and the user experience is optimized.
In the above embodiment, the identifying whether the contact of the target object to the projection area is a valid contact operation according to the size of the infrared light spot further includes: judging whether a second light spot exists in at least one infrared light spot, wherein the size of the second light spot is larger than a first threshold value and smaller than a second threshold value; determining the number of at least one of the second spots in the presence of the second spot; determining that the contact of the second object to the projection area is effective contact operation under the condition that the quantity meets a third preset condition; wherein the second light spot is formed by the reflection of the infrared ray by the second object contacting the projection area, and the target object comprises the second object.
Based on the above embodiment, in the case where there is a second light spot whose size is greater than the first threshold value and smaller than the second threshold value in the infrared light spot collected by the infrared camera, it is determined that the second object corresponding to the second light spot is not an interfering object. Because the number of touch points supported by the touch device is limited, it is further determined whether the number of second light spots meets a third preset condition, for example, the third preset condition is that the number of second light spots is smaller than a number threshold. Under the condition that the number of the second light spots accords with a third preset condition, the contact of the second object to the projection area is determined to be effective contact operation, and the second light spots are effective light spots, so that the effective contact operation which can be supported by the touch equipment can be identified, and the accuracy of the touch operation is improved.
After the determining the size of the infrared light spot and identifying whether the contact of the target object with the projection area is an effective contact operation according to the size of the infrared light spot, the above embodiment may further execute the following technical solutions: and under the condition that the contact of the target object to the projection area is identified as effective contact operation, responding to the effective contact operation, and generating a touch signal corresponding to the effective contact operation.
It should be noted that, since the effective contact operation is identified, the touch signal may be generated in response to the effective contact operation, so as to perform touch control on the touch device according to the touch information number.
Wherein, when the contact of the target object to the projection area is identified as an effective contact operation, the generating a touch signal corresponding to the effective contact operation in response to the effective contact operation includes: determining coordinates of the effective contact operation from the emitted light forming the infrared light spot; and generating a touch signal corresponding to the effective touch operation according to the coordinates.
In the above embodiment, by determining the coordinates of the effective contact operation and generating the touch signal corresponding to the effective contact operation according to the coordinates, an accurate touch signal can be generated according to the effective contact operation, and the accuracy of the touch operation is improved.
The above operation recognition method is explained below with reference to an example, but is not limited to the technical solution of the embodiment of the present application.
The operation recognition method of the embodiment of the application can be applied to desktop projection and infrared touch equipment, for example, the ultra-short-focus desktop projection and infrared touch equipment shown in fig. 2. Fig. 2 is a schematic diagram of an ultra-short focal desktop projection and infrared touch device according to an embodiment of the present application, and as shown in fig. 2, the ultra-short focal desktop projection and infrared touch device 21 projects toward a target area to obtain a projection area 22. The ultra-short-focus desktop projection and infrared touch equipment comprises a projection device, an infrared laser emitter, an infrared camera and a processor.
The ultra-short Jiao Guangji is used for projecting a rectangular picture with a specified size (for example, 23 inches) on a desktop to obtain a projection area; the infrared laser emitter is used for emitting a beam of infrared light, and the infrared light passes through the conical optical device to cover a layer of infrared light on the whole projection area; the infrared camera is used for detecting reflected infrared light formed after infrared light is blocked by the target object, wherein the reflected infrared light forms an infrared light spot; the processor is used for controlling the projection of the ultra-short Jiao Guangji and determining the coordinates of the reflected light received by the infrared camera and the size of the reflected light spot.
FIG. 3 is a flowchart of a method of identifying operations according to another embodiment of the present application, as shown in FIG. 3, comprising the steps of:
step 1: starting up the touch control equipment;
step 2: after the touch equipment is started, the processor controls the ultra-short Jiao Guangji to project;
step 3: controlling the infrared laser to normally emit infrared rays;
step 4: controlling the infrared camera to collect light spots;
step 5: judging whether the infrared camera collects infrared light spots or not;
if no infrared light spot is acquired, step 9 is performed. If the infrared light spots are not collected, the fact that no finger touch is performed in the projection area and no interference object exists is indicated;
if the infrared camera collects the infrared light spots, executing the step 6;
step 6: the processor processes and analyzes the infrared light spot to determine whether the touch operation is effective (i.e., effective touch, such as finger touch).
In the embodiment of the application, when the size of the infrared light spot (for example, the diameter of the light spot) is between 10mm and 20mm, the size can be determined to be caused by finger touch; an infrared spot of 10mm or less is determined as being caused by the presence of a small interfering object (e.g., an interfering object such as a desktop bump, an electric wire, etc.) in the projection area; an infrared spot of 20mm or more is determined to be caused by the presence of a relatively large interfering object in the projection area. For the infrared spots of 10mm or less and the infrared spots of 20mm or more, the interference spots caused by the interfering object and the ineffective contact operation at this time were determined. Since finger touches are typically set with acceptable points (e.g., 10-point touches and 5-point touches) according to the device hardware configuration, valid finger touches within a set point number will respond. Thus, when the infrared spot is an infrared spot between 10mm and 20mm, it is necessary to further determine whether the number of infrared spots between 10mm and 20mm is within the set point number, and if so, the processor determines that the contact within the projected area is a valid contact operation.
If the contact operation is invalid, executing the step 8; otherwise, executing the step 7;
step 7: and performing normal picture response according to the effective touch operation.
Step 8: the processor filters and shields the light spots and does not respond according to an invalid touch operation;
step 9: no touch operation is received and no response is made.
Fig. 4 is a schematic diagram of a touch operation according to an embodiment of the present application. As shown in fig. 4, normal finger touch operation exists in the projection area. The touch control equipment can capture infrared reflection light spots through the infrared camera and accurately identify finger touch control coordinates through calculation, so that the processor can make correct picture feedback response.
The touch device in the related art has very high requirements on the flatness of the desktop. Firstly, the desktop is to be flat and can not be rugged, otherwise, touch control is not available or false triggering is easily caused; secondly, the desktop cannot have foreign matters, such as pens, erasers, wires and the like, otherwise, the desktop can be identified as having objects to trigger touch control to perform touch control response, and when the finger clicks the projection picture (namely the projection area) again. FIG. 5 is a schematic diagram of a touch operation according to another embodiment of the present application, as shown in FIG. 5, in addition to a finger touch, there is an interfering object in the projection area, and at this time, the touch operation is not responded to the finger touch or a disorder of response occurs; thirdly, when one hand presses or arms are positioned in the projection area, the other hand clicks the projection area again, and the response is disordered. FIG. 6 is a schematic diagram of a touch operation according to another embodiment of the present application, as shown in FIG. 6, in which one hand presses on the projection area, and when the other hand clicks on the projection area again, the touch operation responds to confusion. Therefore, in order to achieve accurate touch control, the projection surface must be strictly controlled, otherwise the operation experience effect is seriously affected.
Through the embodiment, the problem that touch experience is affected due to the fact that touch is not flexible and false triggered by the interfering object in the projection area can be solved, invalid touch operation caused by the interfering object is filtered, operation stability of touch equipment is improved, natural smoothness of touch operation is ensured, and user experience is improved.
From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment.
