In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, the present embodiment provides a method for coloring a motion trajectory, including:
constructing a speed matching value reference table, wherein the speed matching value reference table comprises a plurality of standard speed matching values; configuring a plurality of color classes correspondingly based on the number of the standard speed matching values, wherein the standard speed matching values correspond to the color classes one by one; obtaining a speed matching list of the exercise report, respectively comparing a plurality of speed matching parameters in the speed matching list with standard speed matching values, and matching the standard speed matching value which is closest to each speed matching parameter; extracting a motion track in the motion report, and coloring track points in the ith kilometer track by selecting corresponding color classes according to the closest standard speed matching value matched with the ith kilometer track; defining the last track point of the ith kilometer track and a plurality of adjacent track points as a critical point set of the ith kilometer, and performing gradient color processing on the track points in the critical point set by adopting color classes corresponding to the ith kilometer track and the (i + 1) th kilometer track; and returning to the previous step to perform coloring processing on the track points in the ith kilometer track by re-selecting the color class until all kilometer tracks are processed.
In the coloring processing method for a motion trail provided in this embodiment, a reference table of matching speed values is pre-constructed, and color classes corresponding to the standard matching speed values are configured, so as to distinguish and represent different standard matching speed values by using colors, after a motion report is generated from motion data of a user, a matching speed parameter is obtained, since the matching speed parameter can represent time spent in each kilometer of the track, the larger the value of the matching speed parameter is, the longer the running time of the user is, i.e., the slower the running speed of the user is, the closest standard matching speed value of each matching speed parameter is obtained by sequentially comparing each matching speed parameter with the standard matching speed value, and then the kilometer of the motion trail is colored by using the color class corresponding to the closest standard matching speed value of the matching speed parameter according to the matching speed parameter corresponding to each kilometer of the motion report, because the presented color difference of the adjacent kilometer tracks is large, in order to avoid a sharp vision, the embodiment also performs gradient color processing on track points between the adjacent kilometer tracks, so that the color conversion of the adjacent kilometer tracks can be uniformly transited, the finally presented motion track not only can clearly distinguish the speed matching parameters corresponding to each kilometer track, but also can present a more gorgeous and softer UI visual effect through the gradient color design.

During specific implementation, a track point set of a motion track is extracted from a motion report of a user, each track point in the set comprises longitude and latitude information, after track point set data is obtained, the SDK-integrated motion APP calls project-to-Screen location (LatLng var1) of an electronic map to correspondingly convert the longitude and latitude track points in the geographic position into coordinate track points which can be displayed on an electronic screen, the motion track of the user is displayed on the electronic screen, meanwhile, the track points corresponding to each kilometer track in the motion track are distinguished and colored by using the matched colors, and the user can clearly see the approximate time of the user on each kilometer track through the colors.
Specifically, in the above embodiment, the last trace point of the ith kilometer track and a plurality of adjacent trace points are defined as an ith kilometer critical point set, and the method for performing gradient color processing on the trace points in the critical point set by using color classes corresponding to the ith kilometer track and the (i + 1) th kilometer track includes:
arranging a plurality of track point subsets according to a generation time sequence, and defining the last track point of the ith track point subset as a critical point; selecting n track points on the left side and the right side of the critical point, and constructing a critical point set of the ith kilometer; and performing gradient color processing on the track point on the left side in the critical point set by using the color class corresponding to the ith kilometer, and performing gradient color processing on the track point on the right side in the critical point set by using the color class corresponding to the (i + 1) th kilometer, so that the coloring of the track point in the critical point set is uniform and gradually changed from left to right.
In the specific implementation, firstly, the position of a critical point of each kilometer track is searched, namely the position of the last track point in each track point subset, then n track points on the left side and the right side of the critical point are selected to construct a critical point set, each critical point set comprises 2n +1 track points, wherein n is more than or equal to 1, i is more than or equal to 2, and n and i are integers, in addition, in order to ensure the appearance of gradient color display on the motion track, the numerical value of n is limited to be far less than the number of track points in the track point subset, then the left track point in the critical point set is subjected to gradient color processing by using the color class corresponding to the ith kilometer, the right track point in the critical point set is subjected to gradient color processing by using the color class corresponding to the ith +1 kilometer, so that the coloring track in the critical point set uniformly changes from left to right, and the coloring track points at the joint position of two adjacent kilometers are subjected to gradient color processing, and returning to the previous step to re-select the corresponding color class to perform gradient color processing on the next adjacent kilometer track connection position until all gradient color processing at the adjacent kilometer track connection position in the motion track is finished. It can be understood that the track point is a coordinate point of the user position uploaded at regular time in the motion process.
For convenience of understanding, it is assumed that the color of the ith kilometer track is color a, the color of the i +1 kilometer track is color b, wherein the color a and the color b respectively belong to any one of color1, color2, color3, color4 and color5, the color a and the color b may be adjacent color types or non-adjacent color types, which is not limited in this embodiment, 2n +1 track points in the critical point set of the ith kilometer need to be averagely divided into a plurality of parts according to the values of the color a and the color b, for example, color a is color1 and color b is color2, in order to allow the color2 and the color3 to participate in the gradual change color processing, at this time, 2n +1 track points need to be averagely divided into 3 parts, the 1 track point is from color1 to color2, the 2 nd track point is from 73725 to 3, and the color gradually change points are finally exhibited from 3 to 3884 color gradually change points.
